Community Engagement Phase I Overview From August 2019 to January 2020, we gathered input from residents across the County via an interactive website and a series of pop-up events. The same input mechanisms were available online and offline. Input was used to inform the draft Transportation Plan. Online engagement opportunities: ● ● ●

Survey to understand community transportation needs Interactive Map to gather ideas for transportation improvements Poll to gather data on current transportation usage

All online engagement opportunities were also available in analogue form at community events. Community engagement events:

Phase I Community Engagement Process To gather input on the NVTA Countywide Transportation Plan 2045 (“Transportation Plan”) from Napa County’s community members, NVTA worked with contractors DKS and CivicMakers (NVTA team) to conduct a series of in-person and online engagement activities from August 2019 to January 2020.

In-Person The NVTA team hosted a series of pop-up events during popular community events in Napa, St. Helena, American Canyon and Calistoga. At each event, the public was presented with a set of engagement posters to share project information and solicit input on focus areas and measures for the Transportation Plan. The posters were translated to Spanish for targeted events.

Online In addition, a digital engagement platform was launched to amplify reach. The platform was also designed to make it easier, more convenient and accessible to share input on the Transportation Plan. The website (https://www.nvtatransportationplan.org/), available in English, Spanish and Filipino, was set up as a hub for sharing project information, as well as for gathering input via interactive maps and survey components. Text messaging integration was included in order to better reach those people who may not have computers or smartphones at home. All online engagement opportunities were also available in analogue form at community pop-up events. Below is a screen capture of the webpage.

Promotional Campaign To promote the pop-up events and online engagement activities, the NVTA team developed a promotional campaign that included emails, social media, press releases, and printed poster ads on buses, in bus shelters, and in other public places. All materials were translated into Spanish.

Discussion Findings by Focus Area Community sentiment from comments received via digital engagement and pop-up events is summarized below according to the goals of the Countywide Transportation Plan 2045.

Equity Goal: Serve the transportation needs of the entire community regardless of age, income or ability. Most comments related to equity emphasized the need to provide and maintain safe, reliable, and comfortable transportation options to schools for youth (e.g., increase bus service, expand bike routes, and maintained sidewalks). Some comments expressed a desire for better or alternative transportation options for seniors and persons with disabilities, such as on-demand rideshare services because existing transportation options are not considered accessible or comfortable.

Safety Goal: Improve system safety in order to support all modes and serve all users. Most comments expressed a desire to see more safety improvements for bikers and pedestrians (e.g. designated bike lanes, pedestrian signal crossings, etc.). Many comments raised concerns over dangerous vehicular traffic, identifying specific unsafe intersections or crossings and calling for increased traffic calming measures and road enforcement. A few comments asked about planned evacuation routes in the case of an emergency or natural disaster.

Reduce Congestion Goal: Use taxpayer dollars efficiently and reduce traffic congestion. The majority of comments (over 200) were concerned with traffic congestion. Over half of the comments advocated for more frequent, reliable public transportation services that better connect Napa County cities to each other as well as to San Francisco, East Bay, and Sonoma County (at least to the Vallejo Ferry or Richmond Bart). The other comments want traffic congestion alleviation via roadway improvements, such as via synchronized traffic signals, roundabouts, road widening, designated turning and passing lanes, and over/underpasses.

24


Economic Vitality Goal: Support Napa County’s economic vitality. Most comments related to economic vitality want to see better coordination with the wine and tourist industry to manage transportation demand. A few comments (also related to equity) want to see better public transportation options for existing residents/workers and more reliable service to connect residents to economic opportunities inside and outside of Napa Valley.

Sustainability Goal: Minimize the energy and other resources required to move people and goods. Overall, there were few comments explicitly about sustainability. Of those related, some comments advocated for electric vehicles while others discouraged driving in favor of promoting alternative modes of transportation, such as public transit, e-scooters, biking, and walking, through improving efficiency and safety or providing incentives (e.g. free transit passes, helmets, etc.) to protect the environment.

Maintenance & Preservation Goal: Prioritize the maintenance and rehabilitation of the existing system. Many commenters want to see roads maintained and repaved, biking and pedestrian networks continue to be expanded and maintained, and public transportation frequency improved to encourage ridership. Additionally, some commenters felt public transportation could be improved through easier, seamless payment methods and better real-time trip planning tools.

TRANSIT ACCESSIBILITY


TRANSIT BUFFER ANALYSIS MEMORANDUM DATE:

August 19, 2020

TO:

Alberto Esqueda | Napa Valley Transportation Authority

FROM:

Aditi Meshram | DKS Associates Erin Vaca | DKS Associates

SUBJECT: NVTA Countywide Transportation Plan

Project #19118-000

OBJECTIVE

This memorandum describes the methodology for estimating the number of households with lower than median income that are served by Napa’s Vine Transit stops. The accessibility of Vine Transit service is determined by the walkable distance to these transit stops, which is assumed to be one quarter of a mile.

DATA

The following data was utilized for this analysis: 1. Number of households in Napa County – obtained from the American Community Survey (ACS) 2014-2018 2. Census Block Groups shapefile – obtained from TIGER (Topologically Integrated Geographic Encoding and Referencing 3. Vine Transit Stops shapefile – obtained from the NVTA web site.

METHODOLOGY

A combination of Microsoft Excel and ESRI’s ArcGIS was used for this analysis. 1. Load the Napa County Basemap ArcMap file. 2. Add the Vine Transit Stops shapefile to the map. 3. Use the Geoprocessing  Buffer tool in ArcMap to create a 1/4th mile buffer around Vine stops. Select the dissolve option to merge overlapping buffers. Save this buffer polygon feature class in the desired geodatabase.


4. Load the Block Groups shapefile. Using the Geoprocessing  Clip tool, clip the Block Groups to the existing Napa County boundary. This will create a subset of the Block Groups that only lie within Napa County’s boundary. 5. Certain block groups have houses build only over a small portion of their entire area. This is especially evident in block groups outside the dense city center, where built-up area does not cover the entire block group. To obtain the number of households within such transit buffers that lie along the periphery of cities, we calculate the ratio of area covered by transit buffers to the area of residential build-up in the block group, and multiply by the total number of households in that block group. Polygons around built-up residential area are created in Google Maps and imported into ArcMap as shown below.

FI GURE 1. EX AMPLE OF BLOCK GROUPS WI TH S MALL BUILT-UP AREA

6. Load the residential built-up area polygons onto ArcMap. 7. Using the Geoprocessing  Clip tool, join the Block Groups and Residential Polygons. Save as shapefile. Let’s call this “BlockGroup_Poly” for purposes of referencing. The Clip tool will attach the Block Group’s GeoID field to the Polygons shapefile, for easy cross-referencing later.


8. Using the Geoprocessing  Intersect tool, create an intersect between the Block Groups and Transit Buffers. This will split the buffers and divide them across block groups as highlighted in teal below. Save as shapefile and call this “BlockGroup_Buffer_Intersect”

FIGURE 2. CREATE AN INTERSECT OF TRANSIT BUFFER AND BLOCK GROUP SHAPEFILES

9. Using the Geoprocessing  Clip tool, join the BlockGroup_Poly and BlockGroup_Buffer_Intersect obtained in Step 8. Save this as a shapefile and name it as “BlockGroup_Poly_Buffer”. This gives the residential area that is intersected by transit buffers. Area of these polygons can be found under the field “Shape_Area”. Refer Figure 5 to view how each of the layers from Step 7 to 9 look on the map. 10. Export the table data of shapefiles BlockGroup_Poly and BlockGroup_Poly_Buffer. 11. In an Excel Worksheet, import the data from BlockGroup_Poly, BlockGroup_Poly_Buffer and the Demographic data obtained from ACS. Note that GeoID in ACS data is in a slightly different format than that in Block Groups. Edit the ACS GeoID field to match the Block Groups.

FIGURE 3. GEOID FIELD IN ACS 2014-2018

F I G U R E 4 . G E O I D I N B L OC K G R O U P S


12. Using VLOOKUP function in Excel, for every block group obtain the built-up area i.e. Shape_Area of BlockGroup_Poly, and the built-up area intersecting the transit buffers, i.e. Shape_Area of BlockGroup_Poly_Buffer. 13. Calculate the ratio of “Built-up area intersecting transit buffer” to “Built-up area”. Let’s call this “Area Ratio”. 14. Again using the VLOOKUP function obtain the total number of households for every block group. Multiply these by the Area Ratio to obtain an estimate of the number of households served by Vine Transit in that block group. 15. Summarize the number of households within 1\4th mile of Vine transit stops by income category, as shown in Table 1. 16. Obtain the number of households that lie below the median income of Napa, as shown in Table 2. Note that Napa’s median income is $84,753, however ACS income bins are broad, therefore $75,000 has been considered as the threshold income.

Project #19118-000

OBJECTIVE

This memorandum discusses the methodology used in obtaining the number of traffic collisions in Napa County and depicting them on a map.

DATA

Traffic collision data for the state of California is available through the Statewide Integrated Traffic Records System (SWITRS). This data has been geocoded for ease of mapping, and has been made available on the Transportation Injury Mapping System (TIMS) maintained by the University of California, Berkeley Safe Transportation Research and Education Center. Note that the TIMS system includes only injury collision data and does not include property-damage-only (PDO) records. Collision data within the County of Napa was acquired for the years 2015 to 2018.

METHODOLOGY

The SWITRS collision data is mapped in ArcMap of ESRI’s ArcGIS Suite through the following steps: 1. Download the collision data from TIMS and save it as Comma Separated Value (csv) file. 2. Load the Napa County Basemap ArcMap file. 3. Using the Add Data feature, add the collision data csv file to ArcMap. 4. In the Table of Contents, right click on the collision csv layer and select ‘Display XY Data’. Using the dialogue box, set the X Field as LONGITUDE, and Y Field LATITUDE as shown


below. Click OK.

5. A Point feature layer will be added to the map. Right click on this layer, select Data then Export Data. Set the file path for where you wish to save the output feature class, rename the shapefile and hit save. Add the exported data to the map as a layer. 6. Go to Layer Properties of the layer added in Step 5. Under Symbology  Categories  Unique Values, select the value field COLLISIO_1. Use the Add Values button to add collision severity values of 1 and 2, which correspond to Fatal and Severe Injury collisions, respectively.


7. Change the Symbol properties as desired and edit legend to display the feature counts. 8. The raw collision data obtained from TIMS was summarized in Excel using a Pivot Table.

The traffic collisions map of Napa County between 2015 and 2018 is shown in Figure 1. Traffic collisions involving pedestrian and bicycle fatalities are shown in Figure 2. Table 1 summarizes the collisions by city and mode involved. T ABLE 1 . FAT AL AN D SEVERE I NJURY COLLISIONS BY CITY 20 15- 2018

OBJECTIVE

This memorandum describes the methodology for calculating on-time performance and ridership of Vine Transit in Napa county.

DATA

Transit Ridership: •

Vine Transit ridership data from NVTA (FY 2018-2019)

On-Time Performance: • • •

Vine Transit on-time performance data by route for year FY 2018 (routes changed December 2019) Vine Transit ridership data by route for year FY 2018 Routes categorized by o City (Routes 1 to 8) o Intercity (Routes 10 and 11) o Regional routes (Routes 21 and 29)

METHODOLOGY AND RESULTS TRANSIT RIDERSHIP

The Vine transit ridership data obtained from NVTA has ridership data for FY 2018-19 broken down by routes. This data was simply summarized for Commuter Service (routes 10X, 11X, 21 and 29), Regional Service (routes 10, 11, 10X, 11X, 21 and 29) and Local Routes (routes 1 to 8). These are


shown in Table 1. It is recommended that transit ridership be maintained or improved from current levels. T ABLE 1 . VIN E TRANSIT RI DERS HI P BY SERVI CE TYP E SERVICE TYPE

ON-TIME PERFORMANCE

On-time performance and ridership data for year 2018 is available individually for routes 1 to 8, routes 10, 10x, 11, 11x, 21 and 29. Out of these, routes 1 to 8 are considered City Routes, 10 and 11 are Intercity Routes, and 21 and 29 are Regional Routes. This data is depicted in Figure 1 and Figure 2. Since the level of ridership varies across routes, performance was measured to capture how many riders are impacted when a bus is late. Therefore, on-time performance is weighted by ridership for each route category - City, Regional and Intercity. For this, weights are first calculated for each route within a route category based on ridership. These ridership weights are then applied to on-time performance to obtain a weighted average. Calculations are shown in Table 2. On-time performance for City Routes is 79%, for Intercity 63% and for Regional Routes is 65%.

TRUCK TRAVEL TIME RELIABILITY

SUBJECT: NVTA Countywide Transportation Plan

Project #19118-000

OBJECTIVE

This memorandum describes the methodology for calculating the Truck Travel Time Reliability (TTTR) Index for a given set of corridors within Napa County. This index will serve as the freight performance measure for the Napa countywide transportation plan. Results from this analysis are also discussed in the final section of the memo.

TRAVEL TIME RELIABILITY

The TTTR is calculated using data from the National Performance Management Research Data Set (NPMRDS), which provides travel time data for trucks on a given system of roads, mainly Interstate and State highways. 1 The TTTR compares days with extremely high delay to days with average delay, which gives an estimate of unexpected or unplanned delays or reliability. Travel time reliability measures the extent of this unexpected delay. As per FHWA, a formal definition for travel time reliability is the consistency or dependability in travel times, as measured from day-today and/or across different times of the day. 2 Truck Travel Time Reliability (TTTR) is simply the travel time reliability calculated for truck traffic. TTTR is the ratio of the longer travel times (95th percentile) to a “normal” travel time (50th percentile). The TTTRs of a highway corridor’s segments are then used to create the TTTR Index for

2

https://ops.fhwa.dot.gov/publications/tt_reliability/TTR_Report.htm


the entire corridor using a weighted aggregate calculation for the worst performing times of each segment. 3 A higher TTTR Index denotes a less reliable highway. A TTTR Index of 1 represents freeflow conditions. For Interstate highways, a TTTR Index less than 1.69 is considered desirable. 4 For non-interstate highways studied within smaller regions (e.g. Counties or Cities), the TTTR Index can be of much higher value due to the constricted nature of traffic flow in these regions.

The download will contain segment performance data for trucks as well as a segment identification file named “TMC_Identification.csv”. The segment performance data contains speed and travel time information for each segment and for each time stamp. In this case we have obtained data averaged over fifteen minutes. As shown in Figure 2, the data has a column named “tmc_code”. TMC stands for Traffic Message Channel, the purpose of which is to deliver information about traffic. As discussed earlier, each highway is divided into numerous segments and data is collected for each of these segments by TMCs which are identified by unique TMC codes.

METHODOLOGY

The methodology for calculating Travel Time Reliability Index is obtained from a FHWA presentation on “National Travel Time Data Processing and Utilization” by the Office of Highway Policy Information. 5 The freight reliability measure, TTTR, is the sum of maximum TTTR for each reporting segment, divided by the total study corridor miles. The higher the TTTR Index, less reliable is the highway. The method to calculate TTTR for each segment of a given study corridor is detailed in this section. 1. Join the obtained truck data with the TMC Identification information. Filter out the data based on road name of desired highway and create a sub-data set for each highway. For this analysis, four highway corridors have been studied: • • • •

CA-12 CA-29 CA-121 Napa-Vallejo Highway

2. Group the sub-data into 5 time periods for each TMC: • • • • •

Weekday 6:00 - 10:00 am Weekday 10:00 am - 4:00 pm Weekday 4:00 - 8:00 pm Everyday Overnight 8:00 pm - 6:00 am Weekend 6:00 am - 8:00 pm

3. Sort and rank the travel times in each group to obtain 95th and 50th percentile travel times for each TMC segment as shown below. Calculate their ratio to get Truck Travel Time Reliability (TTTR). TTTR = 95th percentile travel time / 50th percentile travel time for each TMC. Find the maximum TTTR out of these. A maximum TTTR will be obtained in this manner for every TMC segment.

4. To obtain the TTTR Index for the entire study corridor, we need length of the TMC segments, obtained from the ‘TMC Identification’ data. Multiply the length of each TMC segment by the Maximum TTTR of that segment. Add all the length-weighted TTTRs for this study corridor and divide by total length of the corridor. This gives the TTTR Index, as illustrated in Figure 5.

5. An overall TTTR Index can be calculated for all four study corridors combined in a similar way by summing the length-weighted TTTR obtained in Step 4 for all corridors and dividing by the sum of lengths of all corridors.

This process (Steps 1 to 4) needs to be repeated for all study corridors. The task of grouping data by time window and sorting to obtain 95th and 50th percentile travel time can become cumbersome when dealing with an entire year’s data containing more than 740,000 records. To make this process easily reproducible, a Python code has been written that calculates the TTTR Index for chosen study corridors. The same inputs are used by this code – NPMRDS Truck Data and TMC Identification file. The code is attached in the Appendix. In order to run the code it is essential to download and install Python 3 (Python 3.7.4 was used for this analysis) 6. An interactive python development environment (IDE) ‘Spyder’ was used to edit and run the code 7. Spyder can be installed using Anaconda Navigator. Python packages NumPy and Pandas have been utilized in the code. Since Spyder is a Python environment, there is usually no need to set up the mentioned Python packages separately. However, in case Pandas and NumPy need to be installed for Spyder, detailed instructions can be found here.

These numbers denote how much longer it takes to traverse a roadway in extremely congested situation (e.g. during an accident) compared to normal conditions. For Westbound CA-12, thirteen miles of corridor length has been analyzed for 2019 giving a TTTR Index of 2.88. With a posted speed limit of 60 mph, under normal conditions the truck travel time along this corridor is thirteen minutes. During an extreme incident this travel time might increase to about thirty seven minutes, obtained by multiplying the normal truck travel time (13 minutes) to the TTTR Index (2.88). Thus, lower TTTR Index implies higher reliability of highway and therefore better on-time performance of freight. The numbers here look slightly amplified because the lengths of study corridors considered are very small compared to statewide Interstate corridor lengths, which have long segments with near free-flow conditions for freight traffic. On the other hand, segments considered here pass through busy regions of Napa County for their most lengths, thereby showing a higher TTTR Index. However, these numbers are useful for defining a baseline at present conditions and setting targets for the Countywide Transportation Plan.

PROPOSED TARGETS

As seen in Figure 7, the Overall Truck Travel Time Reliability Index has seen a decrease from 2017 to 2019. With increasing traffic over time, this decline can be very slow in the future. For the Napa Countywide Transportation Plan (CTP), it is recommended to maintain, or reduce by planned highway improvements, the current overall TTTR Index of 2.09.

SUBJECT: NVTA Countywide Transportation Plan

Project #19118-000

OBJECTIVE

This memorandum describes the methodology for estimating the number of jobs accessible by transit within sixty minutes of travel time.

DATA AND TOOLS

Isochrones of transit coverage were obtained from www.remix.com, centered at five jurisdictions with Napa County and at three different start times per bus schedules: 6:40 AM, 7:00 AM and 7:40 AM. Jobs data was obtained from Census Transportation Planning Product (CTPP) at TAZ level. Data was exported as shapefiles to obtain the area of TAZs. The shapefile also contains job information. Open the shapefile in ArcMap, export the attribute table and save as a CSV file. ArcMap by Esri was used to map the transit coverage and relate the jobs data to the area of coverage.

METHODOLOGY OBTAINING ISOCHRONES FROM REMIX

Go to www.remix.com. Add the Vine Transit lines using Add Transit Line option. Place the isochrone marker “Jane” at the desired location (city center or City Hall). Select the desired start time, wait times based on ‘Timetables’, travel time of 60 minutes and coverage option for jobs.

Select the polygons for “60 minutes” travel time and merge them using the Edit layer option. Save this merged transit coverage shapefile. JOINING JOBS DATA TO SHAPEFILE

Import jobs data into ArcMap. Using the Geoprocessing tool in ArcMap, Clip the jobs data to the transit coverage shapefile. The clipped polygons are shown below. In the attribute table, add a field and calculate the shape area of the clipped polygons. Export the attribute table of the obtained Clip file. This should contain the area of clipped polygons which will be used to calculate the ratio of area of polygons to the total area of TAZs to estimate the number of jobs accessed.

OBTAINING NUMBER OF JOBS ACCESSIBLE

In an excel workbook, import the attribute tables exported in the previous steps as well as the jobs by TAZ data obtained from CTPP. For each field, calculate the ratio of the area of polygon to the area of TAZ. Multiply this ratio by the number of jobs corresponding to that field. This gives an estimate of the number of jobs within the coverage area reachable by transit under sixty minutes from the given start point and within the given time period. In this case, start times of 6:40 AM, 7:00 AM and 7:40 AM were considered to observe maximum transit coverage and number of jobs accessible during the morning commute hours.

TO:

Alberto Esqueda | Napa Valley Transportation Authority

FROM:

Aditi Meshram | DKS Associates Erin Vaca | DKS Associates

SUBJECT: NVTA Countywide Transportation Plan

Project #19118-000

OBJECTIVE

This memorandum describes the methodology for mapping the pavement condition index for Napa county.

DATA

Pavement Condition Index (PCI) at street level and at county level from MTC Vital Signs (2018)

METHODOLOGY

The overall score for pavement condition of Napa County and all jurisdictions within the county are reported at https://www.vitalsigns.mtc.ca.gov/street-pavement-condition under Regional Distribution. The following steps were applied to obtain street level PCI data from MTC: 1. Go to https://www.vitalsigns.mtc.ca.gov/street-pavement-condition


2. Scroll down to the Local Focus section that displays PCI by street segment.

3. Click on “Download Indicator Data From This Page.


4. Select the Street and Roads [Shapefile] data

5. Select Export  Shapefile.

6. Map the PCI for street segments using ArcGIS or other mapping software.

RESULTS

The overall pavement condition index for Napa county is 58, as reported by MTC for 2018. PCI score by jurisdiction is presented in Table 1. The pavement condition of street segments is mapped in Figure 1 and summarized in Table 2. Currently 64% of the streets have Good/Fair or Excellent/Very Good pavement condition. The proposed target is to achieve a countywide PCI score of 80.

TO:

Alberto Esqueda | Napa Valley Transportation Authority

FROM:

Aditi Meshram | DKS Associates Erin Vaca | DKS Associates

SUBJECT: NVTA Countywide Transportation Plan

Project #19118-000

MEMO OBJECTIVE

This memorandum describes the methodology for estimating freight flows of Napa County. Freight flow data is described by its associated travel patterns, which include inbound to the County, outbound from the County, and internal trips that start and end within the County. In addition, freight flows were assessed for two basic categories: •

Flow by weight of shipment

Flow by value of shipment

DATA

Freight Analysis Framework version 4.5.1 (FAF4) estimated 2018 flows Note that the FAF data is aggregated at the San Jose-San Francisco-Oakland, CA area (FAF zone 64). This includes the nine counties of Bay Area: Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano and Sonoma county.

Employment by industry data for the nine-county Bay Area (FAF zone 64) and for Napa County, from Employment Development Department (EDD) 1

Household income and number of households by county from American Community Survey (ACS) 2018 5-year estimates 2

https://www.labormarketinfo.edd.ca.gov/data/employment-by-industry.html

2

Table S1901 for the Bay Area counties.


METHODOLOGY

For disaggregating the regional FAF goods flow data to obtain county-level flow, proportional weighting allocation method has been used. This method allocates values from a source unit to target units proportional to a proxy variable. A proxy variable is a variable that can be easily measured in lieu of another variable that is difficult to measure. We applied employment data as a proxy variable to represent “goods production”, since this data is readily available for Napa County based on industry type. Outbound and inbound goods flow has been assumed to be proportional to the level of relevant industry-specific employment of the County relative to other Bay Area counties. Similarly, median income is the proxy variable for “goods consumption”. For goods flow within Bay Area counties, consumption factor has been calculated using household median income weighted by number of households. The desired FAF flow data was disaggregated to the county level based on these production and consumption factors. The steps to obtain the goods flow estimate for Napa County are detailed below. A screenshot of the resulting calculating is shown in Figure 1. 1. Identify the appropriate proxy variable. Employment by industry and median income weighted by number of households have been chosen as proxy variables for this disaggregation process. 2. Obtain the employment data of the relevant industries mentioned in Step 4 for the entire San Francisco-San Jose-Oakland area (FAF zone number 64), as well as for Napa County alone. 3. Calculate the percent proportion of median income weighted by number of households for each county relative to the parent FAF zone 64. Call this the consumption factor. 4. Calculate the percent proportion of industry employment of each county to the parent FAF region using EDD employment data. This will be referred to as production factor. This should be calculated for the following industry sector groups: a. Total Farm b. Mining, Logging, and Construction c. Manufacturing d. Wholesale Trade e. Retail Trade f. Transportation, Warehousing & Utilities 5. For each of the above industries, identify relevant commodities from FAF data. The complete list of FAF commodity codes is included as an attachment.

For internal goods flow within zone 64 (i.e. the intra-Bay Area flow), multiply the internal flow totals by production factor of the origin county and by consumption factor of the destination county. 8. For outbound goods flow, multiply the total outbound flow from zone 64 with production factor of the origin county.

9. For inbound goods flow, multiply the total inbound flow to zone 64 with production factor of the destination county. 10. Repeat the steps for each industry. Note: As the FAF commodity codes for Manufacturing, Wholesale Trade, and Retail Trade coincide, the estimated goods flow for these industries have been combined as an average of the three.

RESULTS

Out of total 26,798 thousand tons of shipment to, from, and within Napa County, 62% is outbound and about 37% is inbound. As expected, farm products are the largest exports from the county, in terms of both shipment weight and value.

TO:

Alberto Esqueda | Napa Valley Transportation Authority

FROM:

Erin Vaca | DKS Associates Aditi Meshram | DKS Associates Jim Damkowitch | DKS Associates

SUBJECT: NVTA Countywide Transportation Plan

Project #19118-000

OBJECTIVE

This memorandum describes the methodology for estimating the reduction (or savings) in on-road mobile source greenhouse gas (GHG) emissions for the following scenarios: 1. Potential GHG savings if passenger loading on existing express commuter route services provided by NVTA increase by 80%. 2. Potential GHG savings if a 10% mode shift to transit were to occur for the top five divertible commuter markets as identified in NVTA’s Travel Behavior Study (TBS). 3. Potential GHG savings if a 10% mode shift 1 to active transportation were to occur for all trips under 3 miles in length (one-way trip end) based on the TBS. The 10% mode shift is consistent with a goal from the Bike and Ped Plan goal).

DATA AND TOOLS

The following data sources were utilized to inform the mode shift analyses and resulting GHG emission benefits: 1. Streetlight OD trip data and zones for Fall 2018 (August-November) 2. Vine Transit commuter route load factors 3. Vine transit stops and routes

1

A ten percent mode shift is part of the vision statement for the Napa Countywide Bicycle Plan (NVTA, 2019).


4. Google distance API - a service that provides travel distance and time for a matrix of origins and destinations. The API returns information based on the recommended route between start and end points, as calculated by the Google Maps API. 5. QGIS mapping tool - QGIS is an Open Source Geographic Information System (GIS) 6. SB1 emissions calculator – developed by the California Transportation Commission (CTC) to estimate on-road mobile source emissions changes for transportation projects. The tool applies vehicle speed, vehicle type and vehicle technology group corrected on-road mobile source base emission rates consistent from EMFAC emissions model developed by the California Air Resources Board (CARB) for application in California. The methodology is similar to CARB’s California Freight Investment Program.

METHODOLOGY

The following steps were undertaken to estimate GHG savings for each scenario. SCENARIO 1

1. Using QGIS, map the Streetlight OD zones. 2. Create ½ mile buffers around commuter stops and extract zones that intersect with these buffers.

3. To these zones, add zones in San Francisco and Alameda that can be accessed via transfers from El Cerrito BART and Vallejo ferry. This would be the set of zones that can be accessible by transit. Let’s call these “divertible zones”.

4. Using QGIS, find the centroids of each of these zones. 5. Using Google Distance API, find the travel distance array for divertible zones. 6. For these zones, find the trips from Streetlight OD data for the following combinations: a. Trips from zones in Napa county to zones outside Napa b. Trips from zones outside Napa county to zones within Napa

9. Based on Steps 1-8, an estimated 1,133 vehicle trips will be reduced in the AM and PM combined if load factors of commuter routes are increased to 80% 10. Determine the weighted average trip length of all divertible trips to and from Napa County and multiply by 1,133 vehicle trips to yield the VMT reduction/savings. This results in a daily VMT reduction of 227,302.

SCENARIO 2

1. Identify the top five divertible markets from TBS that have access to Vine transit routes. These were identified as Napa County, Solano County, Contra Costa County, San Francisco County and Alameda County. Though Sonoma County is a significant market, it was not accounted for given that it does not have access to Vine routes. 2. Similar to Scenario 1, find the VMT between zones of the identified divertible markets. The following trips were analyzed: a. Napa County to external counties b. External counties to Napa County c. Trips within Napa county that are accessible by transit 3. Calculate the VMT if 10% of above trips shift to transit. All new transit service needed to accommodate this influx of new riders is assumed to be by electric vehicle technology buses and therefore have zero emissions (point source electric generation is not accounted for). 4. Find the average trip length of trips reduced.
