  • Challenges faced by bus service:
    • Crowding
    • Slowing travel speeds
    • Route and schedule adherence
    • Customer expectations
  • Limited short-term strategies available to meet challenges:
    • Manage current bus and rail system to maximize efficiency
    • Deploy additional vehicles
    • Expand bus network to serve new and growing markets

Historic and Forecast Regional Growth

bus transit s regional role
Bus Transit’s Regional Role
  • Buses provide many types of services throughout the region.
  • Bus is the only mode used for many trips in the region.
  • Bus service expansion plans have previously been prepared but not implemented.
  • Bus is the primary mode in many areas of the region.
  • Investments in Buscontribute to healthy communities.
  • Bus can be expanded in near term with projects to meet regional needs.
key regional transit strategies
Key Regional Transit Strategies

Regional/Jurisdictional Initiatives:

Short Term

  • Buses on freeways
  • BRT starter projects (K Street busway etc)

Long Term

  • Regional express bus
  • Completed BRT network
  • Jurisdictionally proposed rail enhancements (LRT, streetcar)
  • WMATA Initiatives:
  • Short Term
  • Metrobus service operational enhancements (skip stop service etc)
  • Regional Transit System Plan to integrate strategies into cohesive plan
  • Long Term
  • ROW dedication for bus
  • Rail expansion
bus family of services concept
Bus “Family of Services” Concept

The Metrobus Priority Corridor Network is a key component of a future enhanced regional bus network consisting of a true family of bus services, including:

  • Bus on dedicated right-of-way
  • Express bus routes on HOV Lanes and Freeways
  • Limited-Stop Express routes on Priority Corridors
  • Community/neighborhood shuttles
  • Local bus routes
  • Commuter bus routes

Characteristics of Priority Bus Corridors
  • Metrobus has 171 lines with total daily ridership of 450,000
  • Corridors represent 14% of lines (50% of ridership)
  • Recommended Priority Corridor Plans serve:
    • 220,000 current daily riders
    • 70 million annual riders
    • 246 line miles of service
  • Corridors include:
    • Local Metrobus
    • Express Metrobus
    • MetroExtra (Rapid Bus)
    • Neighborhood Shuttles
  • Proposals add 10 million riders annually (+14%)
comprehensive approach to bus service improvement
Comprehensive Approach to Bus Service Improvement
  • A Regional Priority Corridor Network Plan will:
    • Integrate service improvements, including new MetroExtra routes
    • Improve performance of all routes in the corridor
    • Coordinate stakeholder investments in stops, roadway improvements and safety/security strategies
  • Implementation:
    • Improves street operations to improve travel times and reliability
    • Manages fleet and garage needs
    • Enhances customer information
  • Focus on Priority Corridors:
    • Benefits the most riders
    • Improves service quality, reliability, performance
    • Builds transit market and influences development patterns
traffic congestion adds costs and degrades service
Traffic Congestion Adds Costs and Degrades Service
  • Bus priority is a cost-effective way of moving more people by increasing passenger throughput at intersections
  • Since CY 2000 Buses have experienced a reduction in average speed :
    • Suburbs: up to 30%
    • City: nearly 15%
  • A 30% increase in average speed for buses on the Priority Corridor Network (12.1 to 15.7 mph) would be like putting 100 more buses on the road.
    • Saving $50 million in capital
    • Avoiding operating costs of $40 - $50 million per year

pcn evaluation project purpose
PCN Evaluation - Project Purpose
  • Quantify regional benefits and impacts resulting from implementation of the PCN
  • Identify and prioritize the most effective running-way improvement strategies for implementation along study corridors , but NOT an implementation plan
  • Develop an analytical framework for evaluating the proposed bus improvements and for inclusion into the CLRP process
  • Build regional consensus for PCN implementation
pcn evaluation administrative overview
PCN EvaluationAdministrative Overview
  • Project is being administered through COG and managed by WMATA
  • Funding for project is utilizing WMATA, DDOT, MDOT and VDOT technical assistance funds (portions of 2008 and 2009)
  • Will present key milestones to TAC then JCC and TPB
  • Project timeline coincides with CLRP update
  • Study completion by end of 2009
  • Technical advice and guidance from a regionally represented Technical Advisory Committee
pcn evaluation scope
PCN Evaluation - Scope
  • Development of Analytical Approach
  • Develop transit network input assumptions
  • Network Evaluation
    • CLRP Baseline
    • Full Build
      • Assuming a dedicated transit lane for all 24 corridors
      • Will show the “transit best case” benefit basket of priority corridor implementation
    • Modified
      • Segments that have low performing transit ridership or too high an impact on adjacent traffic will be assumed to have mixed traffic operations with intermittent intersection improvements (ie queue jumps etc)
pcn evaluation analytical approach
PCN Evaluation – Analytical Approach
  • Divide each PCN corridor into “segments”
  • Compile characteristics of each segment (number of lanes, existing transit ridership etc)
  • Develop list of enhancements by investment level (high or medium) and adjacent urban form (urban, inner suburban and outer suburban)
pcn evaluation analytical approach continued
PCN Evaluation – Analytical 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

TAC Involvement (cont.)

  • “Transit best case” is meant to show the upper limits of PCN system benefits.
    • It is a theoretical exercise
    • It will help inform “modified” network run, which is intended to be a more realistic scenario
    • Currently, transit best case run is envisioned to show a bus only exclusive lane on all 24 corridors
    • Model output will be analyzed to discern impacts on traffic, bus ridership etc.
    • TAC input/discussion
the tpb role
The TPB Role

The TPB can provide support of this Bus Priority Corridor Plan by:

  • Ensuring that related policy considerations are discussed in various committees and forums available to the TPB:
    • Regional Bus Subcommittee
    • Management and Operations Intelligent Transportation Systems (MOITS) Task Force
  • Exploring strategies for acquiring additional funding support for the capital improvements included in the plan:
    • Existing and future federal programs
    • Regional pricing initiatives
  • Partnering with stakeholders in the region to develop implementation strategies:
    • This could include convening meetings of regional stakeholders to discuss policy considerations and develop regional consensus on strategies needed to insure success of the plan.

Requested Emerging Corridors

  • Corridors for future consideration as Priority Corridor Network candidates.
  • Local concept development studies are to be conducted to refine proposals for future consideration before implementation as part of WMATA plan.
