San Joaquin Valley Blueprint

San Joaquin Valley Blueprint. Smart Growth PrinciplesCreate lower dependence on typical transportation conceptsSteer away from primary mode of automobile travelIncrease viability and attractiveness of alternative modes of transportation (walking, biking, transit, etc.)Translation to local agencies:Adoption of goals and policies in updated General PlansSignificant impact to the traditional development of the circulation systems.

Presentation Transcript

    6. Traffic Signal Management Benefits of active signal management Travel time savings for all modes of travel Reduces problems associated with aggressive driving Postpone additional capacity improvements Reduces accidents through smooth flow and reduced stops Improved pedestrian flows Active side street flow with minimal main street delay

    7. Traffic Signal Coordination

    8. Traffic Signal Coordination Coordination Goals Key modes of travel Key travel times Coordination Process Preliminary Study Analysis of Existing conditions Benefits of coordination Reduction in travel time, stops, fuel, emissions, etc. Hardware upgrades Preliminary coordination plan Report (Cost – Benefit Analysis)

    9. Funding Options Federal SAFETEA-LU Surface Transportation Program (STP) Congestion Management and Air Quality (CMAQ) State Proposition 1B State Transportation Improvement Program (STIP) Traffic Congestion Relief Program (TCRP) Regional and Local Transportation Development Act (TDA) Developer Funded Improvements Regional Sales Tax Gas Tax

    10. Traffic Signal Coordination (cont’d) Types of coordination Time based coordination Closed loop systems Hardwire interconnect (coaxial, fiber optic, telephone) Wireless (spread spectrum radio, wi-fi) Monitoring Traffic Operations Center (TOC) Centralized location to monitor multiple signals and coordinated corridors Monitoring available via intersection detection (loops, video) Provides immediate observation and response to signals

    11. Traffic Signal Coordination (cont’d) Analysis Synchro – Simtraffic Input signal timing parameters Develop coordination offsets Calculate changes

    12. End Results Determine final results Field observation Actual travel times Queue lengths Monitoring Software analysis Emissions, stops, fuel reduction

    14. Project Map

    15. Project Overview Data gathered by consulting team Synchro used to develop a coordination model Optimization of model Field implementation and final report

    16. Synchro Analysis Package Purpose and Use Overview of Process Discussion of Output Timing plans for individual intersections Phase plans for individual intersections Optimization plans Time – Space diagrams Measures of Effectiveness Volume to capacity ratios Vehicle delay Vehicle stops

    17. Specific Hardware and Timing Changes Hardware Upgrades and Changes Changes in Intersection Timings Time – Space Diagrams New Timing Plans Public Reaction to Coordination

    18. Time - Space Diagram (Westbound plan)

    19. Time - Space Diagram (Average)
