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

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

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
