  1. City of Alexandria VirginiaTransportation and Environmental Services ITS technologies on Route 1 Transitway Project Ravi Raut, P.E. June 2014

  2. Route 1 Transitway - Location Map • 5-mile corridor between Pentagon City and Braddock Road Metrorail stations • 80% of corridor in dedicated right-of-way • 30 Transitway stops within the corridor • Expected daily ridership of 3,570 by 2017 • First 0.8 mile segment in Alexandria currently under construction

  3. Rt 1 Transitway- Alexandria Section • Route 1 northbound widened by Potomac Yard South Developer • 2-lane transit-only corridor with 12-ft landscaped medians on both sides • Medians taper to allow for left-turn lanes at signalized intersections

  4. Rt 1 Before construction

  5. Rt 1 During Construction

  6. Typical Transitway Route 1 intersection

  7. ITS applications on Transitway Transit Signal Priority Queue jump Costumer Information Electronic Display (CIED) signs Bus Fare collection

  8. Choosing TSP locations Transit Priority and Queue Jump • Intersection LOS/Delays • Bus stop location • Number of passengers • Detectors on side street • 3 TSP and 2 Queue jump locations

  9. TSP Operation AVL system – Clever Devices IVN and BusWare software TSP software run on IVN platform and works with BusWare BusWare looks at all operational data and determines if request is met. If request is met, Busware invokes TSP software. TSP software (via onboard cellular modem) initiate dialogue with intersection (via intersection cellular modem) Intersection modem transmits the data to correct phase selector Phase selector makes priority decision at the intersection Central Management software (CMS) enables system manager to monitor, maintain and configure the TSP system from central location

  10. TSP operation

  11. Traffic signal cabinet - TSP

  12. Transit Priority technics Green extension If the signal is green but about to turn red and if bus is behind schedule – add few seconds of green time for approaching transit Early green If the signal is red - truncate the red phase for approaching transit

  13. Queue Jump

  14. Queue Jump

  15. Typical Transit Station

  16. BRT bus fleet

  17. CIED signs CIED sign ADA Pushbutton

  18. CIED sign Operation

  19. Display sample ETA time – Real time (rt) Schedule time (s) Alert/Ad hoc messages

  20. User Interface Add sign

  21. User Interface Delete sign

  22. User Interface Edit bus stop

  23. ADA pushbutton • Pressure activated • Button produces a beep and LED flashes when button activated. • Audio announcements of what is being displayed on sign can be heard with press of audio push button • Braille Placard with instructions

  24. Fare collection • Proof-of-payment system • Time-stamped paper tickets purchased at vending machine (TVM) on platform • Passengers board at all doors without showing tickets to operator • Inspectors board vehicles or monitor station platforms periodically to inspect tickets • 3 TVMs per platform • 2 SmarTrip-compatible TVMs • 1 machine that accepts credit cards/coins
