2
Agenda Priority Bus Elements and Their Potential Effectiveness PCN Corridor Segmentation PCN Goals, Objectives and Measures of Effectiveness
3
Features of Priority Bus Exclusive or semi-exclusive lanes Fewer stops Off-board fare collection Traffic signal priority Real time information Branding Level boarding

Projects and Case Studies Springfield, MA Los Angeles Metro Rapid (Red Line) Los Angeles Orange Line New York +selectbus Kansas City Silver Line - Boston Salt Lake City (SR 171 / 3500 South) Las Vegas Cleveland

Springfield MA First transit vehicle priority system in region Four Mile - Sumner Ave/ Allen Ave Corridor Includes 9 existing traffic signal locations Facilitate direct service to downtown area Project Overview
7
Transit Priority Priority differs from preemption in that the controller never leaves coordination and no phases are skipped during an event.
8
Springfield MA Desire to provide improved express transit service along existing bus route Reduce Congestion Reduce VMT/Emissions Improved Schedule Adherence Increase Ridership Efficient implementation of system on limited budget Project Objective
9
EXISTING PVTA G1 ROUTE (NON – EXPRESS) Springfield MA Route length: 15 miles Schedule: 50 trips/day

KC MAX Results MAX opened in July 2005 Ridership up 50% Pre-MAX: 3200/day Current: Over 6000/day High Level of Public Acceptance and Satisfaction
29
KC Traffic signal priority Upgraded controllers and interconnect (fiber) New signal timings TSP when >1 min. late No Operator Interaction Goal: 60 % to 70% TSP granted

PCN Corridor Segmentation
45
PCN Evaluation Analytical Approach 45 Divide each PCN corridor into “segments” of no less than two miles Compile characteristics of each segment (number of lanes, density, etc.) and characterize segment by adjacent urban form (urban, inter suburban and outer suburban) Develop list of enhancements by investment level (high, medium or low) and adjacent urban form
46
Analytic Approach (continued) Develop benefits per bus treatment (increased bus speed from TSP, queue jumps, exclusive lanes etc) After initial “full build” model run identify PCN characteristics to be applied to each segment Input into model for “modified” network
47
Corridor Segmentation Methodology Decision factors for where to cut segments: Always cut at intersections Number of lanes, particularly a change from 3 to fewer, and functional classification Household and Employment Density Area Type (as defined by model, compilation of household and employment density)
48
Corridor Segmentation Methodology (continued) Recorded additional corridor and segment characteristics WMATA routes and local bus routes Available median and/or parking lanes Transit ridership Effective headway Availability of existing park and ride locations Characterized each segment by urban form
49
Segment Overview 49 24 Corridors Approximately 233 miles as roughly measured in GIS 120 segments Average segment length is 1.95 Originally planned for segments to be ≤ 2 miles Some portions of the corridors go off the main corridor at beginning and/or end to reach Metrorail Station or transfer center Will be separating those from the main portion of the corridor.
50
Next Steps to go from Segments to Characteristics 50 Review segments with TAC Determine recommended improvements for each type of urban form for each level of investment.

57
Goal 3 Improve Efficiency of System 3.1: Maximize utilization of roadways by people 3.2: Reduce the cost of providing bus service 3.3: Increase average speed for bus passengers in corridors 3.4: Maintain auto passenger speed within corridors 3.5: Improve speed for all passenger trips in corridors 3.6: Reduce vehicle miles traveled (VMT) 1. People served per new lane 2. People served per converted lane 3. Bus hours needed for service 4. Number of buses needed 5. % change in bus passenger times for trips through and within all corridors 6. % change in auto passenger times for trips through and within all corridors 7. % change in times for all (auto and bus) trips through and corridors 8. % change in bus VMT 9. % change in auto VMT ObjectiveSMOEs
