ATCS System- TPS Sub-System

Transit Priority System (TPS)

TPS Data - Intersection Status

(Normal, Failed, Priority)

- Bus Location- Activate/Disable

Priority



TPS - Utilizes specially cut loop

detectors at major intersections and transponders attached to the buses to track the buses



TPS - Bus routes are typically along

the signal timing sync phases of intersections

- The 2070 Controller provides either an early green or late green extension to the sync phase when the bus is behind schedule

- There are more than 26 TPS Routes in LA (1,200+ signals)

TPS - ATCS intersectional

graphical display (Vermont Ave. and Wilshire Blvd.)



2070 Controller - The 2070 Controller allows

for the input of the minimum phase splits, early green values, late green values, and number of cycles to inhibit between bus priority

-Concept of “Partial Priority.”


Orange Line Bus Priority System

Orange Line - Utilizes the 2070 Controller

BRT Program for Bus Priority

- Intersection Status(Normal, Failed, Priority)

- Bus Location


Metro Orange Line Bus TransitwayOrange Line - Buses have dedicated

signal phases - Bus phase may operate

compatibly with some normal pedestrian and vehicular phases
