Metro Orange Line • •

October 28, 2005 Over 83,000 people rode the line on opening day

Page 17


Grade Crossings • 14 mile exclusive ROW • 14 stations

• 6 park & ride lots • 8 miles of bike lanes • 80 acres of landscaping

Page 18


Station Layout


Orange Line is a Success • 25,000 weekday boardings • 1/3 of Orange Line customers are new riders to transit • 77% of Metro customers who previously drove or carpooled indicated reduced travel times • Safety record has improved significantly

ATCS System- TPS Sub-System † Transit Priority System (TPS) TPS Data - Intersection Status (Normal, Failed, Priority) - Bus Location - Activate/Disable Priority


ATCS System- TPS Sub-System † Transit Priority System (TPS) TPS - Utilizes specially cut loop detectors at major intersections and transponders attached to the buses to track the buses


ATCS System- TPS Sub-System † Transit Priority System (TPS) TPS - Bus routes are typically along the signal timing sync phases of intersections - The 2070 Controller provides either an early green or late green extension to the sync phase when the bus is behind schedule - There are more than 26 TPS Routes in LA (1,200+ signals)


ATCS System-TPS Sub-System † Transit Priority System (TPS) TPS - ATCS intersectional graphical display (Vermont Ave. and Wilshire Blvd.)


ATCS System- TPS Sub-System † Transit Priority System (TPS) 2070 Controller - The 2070 Controller allows for the input of the minimum phase splits, early green values, late green values, and number of cycles to inhibit between bus priority -Concept of “Partial Priority.”


ATCS System- TPS Sub-System † Orange Line Bus Priority System Orange Line - Utilizes the 2070 Controller BRT Program for Bus Priority - Intersection Status (Normal, Failed, Priority) - Bus Location


ATCS System- TPS Sub-System † Metro Orange Line Bus Transitway Orange Line - Buses have dedicated signal phases - Bus phase may operate compatibly with some normal pedestrian and vehicular phases


ATCS System-TPS Sub-System † Metro Orange Line Bus Transitway Orange Line - ATCS intersectional graphical display (Chandler Blvd., Coldwater Canyon Blvd., and Busway)


ATCS System- TPS Sub-System † Metro Orange Line Bus Transitway Orange Line - Sample Phase Diagram from 2070 Controller BRT Timing Chart - (Chandler Blvd., Coldwater Canyon Blvd., and Busway)


ATCS System-TPS Sub-System † Metro Orange Line Bus Transitway Orange Line - 2070 Controller BRT Timing Chart Page - This page allows for the input of timing related to the operation of the Bus Line System (e.g. Compatible Phases, BRT detector info, etc.)


ATCS System-Light Rail Transit † Metro Blue Line Light Rail Priority Blue Line - Utilizes the 2070 Controller LRT Program for Light Rail Priority - Intersection Status (Normal, Failed, Priority) - Train Location


ATCS System-Light Rail Transit † Metro Blue Line Light Rail Priority Blue Line - Light Rail Trains have dedicated signal phases - Train phases may operate compatibly with some normal pedestrian and vehicular phases


ATCS System-Light Rail Transit † Metro Blue Line Light Rail Priority Blue Line - ATCS intersectional graphical display (Main St. & Washington Blvd.)


ATCS System-Light Rail Transit Blue Line - Sample Phase Diagram from 2070 Controller LRT Timing Chart (Main St. & Washington Blvd.)


ATCS System-Light Rail Transit Blue Line -The LRT Timing Page allows for the input of timing related to the operation of the Light Rail System (e.g. Compatible Phases, LRT detector info, etc.) -Concept of “Full Priority.”


LADOT SOFTWARE SUITE † LADOT Software Suite: 1. Central Systems: ATCS, TRAFGRAPH; and STPM 2. Type 2070 Controller Firmware: TSCP with BRT and LRT, and HRI (IEEE 1570) 3. Type 2070 Controller Firmware: TPS, match-able to BiTrans 2033 firmware 4. Distribution and Tech Support Available by McTRANS Center, FHWA Software Depot
