TransportationCommission | 2007-05-23 | 4 | 7B. AC Transit Line 51 Task Force. Outcome: Review Line 51 data and provide comments to staff. Staff Bergman presented the staff report, and noted that bus bunching along the 51 Line is being addressed by the task force assembled by AC Transit. He described the route of Line 51 and noted that it had the highest patronage in the AC Transit system, with approximately 22,000 boardings daily. Headways were generally eight to 10 minutes, and running time changes would be implemented in June, which would add nine minutes of running time during the afternoon peak period in the southbound direction, and eight minutes in the northbound direction. The operating speed would be approximately nine miles per hour, which is 25% slower than the district system average. The additional running time would require an additional two vehicles to meet the scheduled service frequency. He described the makeup of the task force, and noted that several variables were examined, including running time, boardings, service deployment policies, AC Transit service policies, using the TRB Transit Capacity and Quality of Service Manual. The staff report indicated what tasks had been completed to date, as well as the future items to be examined. The statistical baseline would be developed; service delivery options would be identified; and service design options would be examined. He detailed the attachments distributed to the Commission. Tony Bruzzone, AC Transit, noted that their Board requested that they look into this problem, and added that it was not a new problem. He noted that they were engaged in new data collection. They intended to have AC Transit staff ride the buses with a laptop, inputting every delay that occurs to identify the specific causes. He noted that was an intensive effort that would take about two months, and that they will collect the data after Labor Day. This will allow the new schedule to be implemented, and avoid data collection during the summer when ridership is lower. Chair Knox White noted that the Task Force was a staff body, not a public body. He noticed that the plan did not identify a deliverable, which was the identification of existing problems. Mr. Bruzzone confirmed that was part of the statistical baseline, and noted that the formal work plan included deliverables that were not included in the summary. Commissioner Krueger noted that since 1998, there had been a brief improvement before it slid back. He believed there should be some permanent monitoring, and inquired about AC Transit's commitment to ongoing monitoring. Mr. Bruzzone replied that the section on service delivery addressed that issue, and noted that the Board was very interested in getting good data on a consistent basis. He added that there was an ongoing discussion about what the benchmarks should be. Commissioner Krueger noted that the discussion about running time under "Measurable Objectives" read, "While in motion, the average speed of the bus is 9.9 miles an hour." He inquired whether it discounted dwell time. He inquired what the average speed was, including Transportation Commission May 23, 2007 Page 4 of 12 | TransportationCommission/2007-05-23.pdf |
