  1. Overview of Rapid Bus Measures and Effectiveness And Case Studies Presentation to TAC June 17, 2009

  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

  4. 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

  5. Limited Stops with Bus Signal Priority Springfield MA

  6. Springfield MA Project Overview • 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

  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 Project Objective • 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

  9. Springfield MA • Route length: 15 miles • Schedule: 50 trips/day Existing PVTA G1 Route (Non – Express)

  10. Springfield MA PVTA G1 Express Route • Route Length: 8.0 miles • Schedule: 10 trips/day

  11. Springfield MA - Benefits • Travel time • Sumner Ave • 4miles, 3 min saved • Downtown • 4 miles, 10 min saved • Congestion Ratio • Before: 1.23 • After: 1.14 • Ridership + 8%

  12. Los Angeles Metro Rapid

  13. LA Metro Rapid As of 12/2008: • 26 Metro Rapid lines • 400 miles of service • 250,000 weekday boardings

  14. Ventura Blvd Performance Topanga Canyon to Vineland, 14 miles

  15. Ventura Boulevard Travel Delay Analysis

  16. Conclusions from Ventura Boulevard • Travel times reduced 23% • One-third of savings due to traffic signal priority • Two-thirds of savings due to lane priority and fewer stops

  17. LA Metro Rapid – Wilshire/Whittier

  18. Wilshire/Whittier Boulevard Travel Delay Analysis

  19. New York City +selectbusservice Source: Woodford, et al (2009)

  20. New York +selectbusserviceOverview • Local funding • Dedicated curb lane • Transit signal priority • Off-board fare collection • Leading bus interval • Customer ambassadors • On-board cameras • Branding • New stations

  21. New York +selectbusserviceFirst Implementation – Bx12 - Fordham Road

  22. New York +selectbusserviceBx12 – SBS 6-Month Outcomes • 18-20% improvement in running time, • Ridership increased 11% • Customer response: • 89% say SBS service is better than the limited. • 30% say that they are riding more frequently than before • 68% say that paying on the street is more convenient

  23. New York +selectbusserviceLane Configuration Between stations At stations

  24. Kansas City BRT Metro Area Express (MAX) TRB BRT Conference, July 21, 2008

  25. KC MAX Bus-Only Lanes • Street Capacity Available • Peak Hour Bus-Only Lanes • Full –Time Bus-Only Lane Downtown • Bus-Only Lanes 52% of MAX • Meets FTA “Fixed Guideway Requirement” for New Starts

  26. HNTB Graphic

  27. 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

  28. 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

  29. KC MAX Street Operations • 7 days per week • 4:30 AM to midnight • 9 minute headways AM & PM • 15 minute headways midday, Saturday, events • 30 minute headway nights and Sundays • Plaza to Downtown: 18 minutes down from 24 minutes • Local bus service paired with MAX in corridor

  30. Las Vegas Metropolitan Area Express

  31. LV Travel Time Results Average Weekday Travel Times (min) on Route 113 and MAX by Time of Day

  32. LV Dwell Time Results Average Weekday Dwell Times (sec) on Route 113 and MAX by Time of Day

  33. How LV Passengers Felt Their Travel Time Changed

  34. Summary Findings

  35. Effect of Bus Stops on Bus Speeds

  36. Dedicated Bus Lane vs. General Purpose Bus Lane

  37. Dedicated Bus Lane vs. General Purpose Bus Lane

  38. Use of Exclusive or Semi-Exclusive Lanes

  39. Traffic Signal Priority Results

  40. Observed Priority Bus Station Spacings

  41. On-Board vs. Off-BoardFare Collection Bus Passenger Service Times (sec/passenger)

  42. Riders from Private Vehicles

  43. PCN Corridor Segmentation

  44. PCN Evaluation Analytical Approach • 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

  45. 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

  46. 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)

  47. 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

  48. Segment Overview • 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.

  49. Next Steps to go from Segments to Characteristics Review segments with TAC Determine recommended improvements for each type of urban form for each level of investment.
