Oakland Airport Connector Options Analysis Analysis of the Options
August 2010
•
Walk time from the middle of the BART train platform to the middle of the Oakland Airport Connector platform (including time on escalators),
•
Average wait time for the next Connector departure to the airport (assumed to be half the headway),
•
Average one‐way in‐vehicle time on the Connector (from the previous step),
•
Average time to deboard from the Connector, and
•
Average walk time from the middle of the Oakland Airport Connector platform at the airport to a terminal entrance (including time on escalators and an assumed average 30‐ second delay at the crosswalks across the terminal roadway, estimated from field measurements).
Walk time was estimated using a walking speed of 4 feet per second, escalator speed of 100 feet per minute, walk distances from a previous step, and typical escalator dimensions. Boarding time is incorporated into the average wait time for the next Connector departure, as it is assumed the next vehicle will arrive at a station shortly after the previous one departs. Deboarding time assumes 2 seconds per person per door on AGT, 5 seconds per person per door on buses (assuming congestion around the bus luggage racks), 2 doors per vehicle for AirBART, 3 doors per vehicle for the other options, and 25 persons per vehicle. Table 4 gives the transit travel time results. Table 4

Table 4 shows that Rapid Bus and AGT have the same overall transit travel times in 2013 and that Full BRT is faster than either of these by 1.0 minute. AGT’s superior in‐vehicle travel time and deboarding time is offset by the longer walking distances required at both ends of the AGT trip, particularly to Terminal 2. In 2030, Full BRT is faster than AGT by 0.3 minutes, while AGT is faster than Rapid Bus by 1.6 minutes. Kittelson & Associates, Inc.
