Presentation Transcript

  1. Transit in TSMO:Bus On Shoulder June 25th, 2019 Caralee Jaeckels, Kimley-Horn

  2. Agenda • TSMO Basics • Bus On Shoulder Basics • San Diego Case Study

  3. Transportation Systems Management and Operations

  4. Transportation Systems Management and Operations

  5. TSMO Has High B/C

  6. Bus On Shoulder • Leverage existing assets • Bypass freeway congestion • Improve transit schedule reliability

  7. Transit Only Lanes Pilot • 3-year Demonstration Starting 2020 • Convert freeway shoulders into Transit-Only Lanes (TOL) • Demonstrate v2i for ramp metering safety enhancements when buses enter potential conflict areas

  8. Project Map • Chula Vista to Downtown San Diego • Part of the South Bay Bus Rapid Transit corridor

  9. Institutional Collaboration • Project Charter • Decision Document • Ongoing coordination in project meetings

  10. Operational Management • Enter TOL (i.e. shoulder) only when adjacent speeds are below 35mph • Keep the bus speed within 15 mph faster than the adjacent speed of traffic on the regular lanes, and not faster than 35 mph • Operator will always operate with caution in conflict zone

  11. Transportation Systems: V2I Technology Integration of a Transit Priority System with ramp metering Utilizes vehicle-to-infrastructure communications (e.g. DSRC) to support safe maneuvers Vehicles held at ramp meter to allow the bus to travel unimpeded Ramp meter hold includes static and activated signs

  12. Transportation Systems: On-Bus Technology Forward Collision Warning Lane Departure Warning Blind Spot Warning

  13. Performance Metrics Customer: Transit schedule reliability Transit operator: Effectiveness of technology

  14. Summary
