Slide 1: Transit Signal Priority Program Timeline, cont’d

2002 – Final acceptance & Aurora Ave. evaluation
2002 – Software Updates contract
2003 – Smart Bus demonstration
2004 – Reengineering concept development and research
2006 – Peer Visit to LA
2007 – OBS contract signed, RapidRide (BRT) program begun
2010 – First RapidRide corridor in service

Slide 2: Existing King County TSP System

1991 – Rainier Ave HOV study recommends demonstration of Transit Signal Priority
1993 – Regional Oversight Committee formed
1994-1996 – RFI, RFP, Contract Award

[Diagram that shows existing King Country TSP system. Shows location of signal priority equipment installed around the intersection. Installed equipment consists of 1) antenna, 2) reader, 3) traffic signal controller, 4) lonworks to interface unit. Diagram shows bus with a transponder traveling through the intersection, activating the signal priority system. ]

Slide 3: TSP System Reengineering Concept

Communication using Wi-Fi Technology
Location using GPS
Eliminate costly reader
Improve system flexibility

[Slide shows same intersection diagram as shown in slide 3 with a reengineered concept of the TSP system. In this system, the reader has been replaced by 802.11 wireless communications. ]

Slide 4: LA Peer Visit Key Findings

802.11 WiFi appropriate for vehicle-to-roadside communications
Latency issues are resolvable
Communication Network O&M access will be critical

The network can be more than just a detection system

Slide 5: RapidRide ITS Architecture
