Springfield MA Limited Stops with Bus Signal Priority
-
Springfield MAFirst transit vehicle priority system in regionFour Mile - Sumner Ave/ Allen Ave CorridorIncludes 9 existing traffic signal locationsFacilitate direct service to downtown area
Project Overview
-
Transit Priority
Priority differs from preemption in that the controller never leaves coordination and no phases are skipped during an event.

SYSTEMIMPLEMENTATIONBENEFIT
Seattle2.1-mile TSP system on Rainier Avenue.Average signal delay was reduced from 7.9 seconds to 3.3 seconds (57% reduction). Effects to side street and overall intersection delay were insignificant.
Los Angeles: LADOT and LACMTA985 intersectionsUp to 25% reduction in bus travel times due to the TSP system.
Phoenix7 intersectionsReduced signal delay for buses by 16%. Impact on cross traffic was minimal.
Tacoma, Washington222 intersectionsCombination of TSP and signal optimization reduced transit signal delay ~40% in two corridors
Chicago : PACE22 intersectionsAverage 15% reduction (3 mins) in running time. Actual running time reductions varied from 7% to 20% depending on the time of day.

PCN Corridor Segmentation
-
PCN Evaluation Analytical Approach*Divide each PCN corridor into segments of no less than two milesCompile 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
-
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 segmentInput into model for modified network
-
Corridor Segmentation MethodologyDecision factors for where to cut segments:Always cut at intersectionsNumber of lanes, particularly a change from 3 to fewer, and functional classificationHousehold and Employment DensityArea Type (as defined by model, compilation of household and employment density)
-
Corridor Segmentation Methodology (continued)Recorded additional corridor and segment characteristicsWMATA routes and local bus routesAvailable median and/or parking lanesTransit ridershipEffective headwayAvailability of existing park and ride locationsCharacterized each segment by urban form
-
Segment Overview*24 CorridorsApproximately 233 miles as roughly measured in GIS120 segmentsAverage segment length is 1.95Originally planned for segments to be 2 milesSome portions of the corridors go off the main corridor at beginning and/or end to reach Metrorail Station or transfer centerWill be separating those from the main portion of the corridor.
-
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.

Project GoalsGoal 1: Improve competitiveness of bus transitGoal 2: Support existing and planned land use and economic developmentGoal 3: Improve efficiency of transportation system

Project GoalsGoal 1: Improve competitiveness of bus transitGoal 2: Support existing and planned land use and economic developmentGoal 3: Improve efficiency of transportation system
-
Goal 1 Improve Competitiveness of Bus Transit 1.1: Increase average bus speed 1.2: Increase bus ridership1.3: Increase number of jobs that are accessible by a 45 minute transit trip.1.4: Improve travel time of transit relative to auto
Percent increase in average peak period bus speed Percent increase in average off-peak bus speed Percent change in average travel time per passengerAnnual passenger travel time savedPercent increase in average peak period bus ridership Percent increase in average off-peak bus ridership Percent change in regional bus ridershipPercent of jobs within 45 minutes by transit to householdsThe ratio of transit travel time to auto travel time
ObjectivesMOEs
-
Goal 2Support Land Use & Economic Development 2.1: Provide transit service within walking distance of existing and planned households and jobs.
Increase the number of households within mile of express bus stopsPercent of households within 45 minutes by bus to job centersIncrease the number of jobs within mile of express bus stopsPercent of jobs within 45 minutes by bus to corridor householdsObjectiveMOEs
-
Goal 3 Improve Efficiency of System 3.1: Maximize utilization of roadways by people3.2: Reduce the cost of providing bus service3.3: Increase average speed for bus passengers in corridors 3.4: Maintain auto passenger speed within corridors3.5: Improve speed for all passenger trips in corridors3.6: Reduce vehicle miles traveled (VMT)
