1	Safety Pilot Model Deployment Transit Safety Applications ITS Workshop on Connected Vehicles Moving from Research Towards Implementation Chicago, IL September 25, 2012 Steve Mortensen Federal Transit Administration
2	Topics Transit Crash Statistics Safety Pilot Model Deployment – Transit Safety Retrofit Package (TRP) Next Steps & Potential Future Research
3	Transit Crashes Over $250M in damages annually Over 100 fatalities with thousands of injuries annually Less than 1% of total traffic crash casualties, but often the front-page news
4	Fatal Crash Characteristics
5	Fatal Traffic Crash Types
6	Transit Safety Retrofit Package (TRP) Five Safety Applications: Pedestrian in Signalized Crosswalk Warning - V2I Vehicle Turning Right in Front of Bus Warning - V2V Forward Collision Warning (FCW) - V2V Emergency Electronic Brake Lights (EEBL) - V2V Curve Speed Warning (CSW) - V2I Phased Deployment: Phase 1: FCW, EEBL, and CSW, August 2012 Phase 2: Integrated Data Acquisition System (DAS), October 2012 Phase 3: Remaining two applications and bus driver training, December 2012
7	Pedestrian in Signalized Crosswalk Warning Provide bus driver a warning when a pedestrian is crossing the street as the bus is making a turn Application relies on infrastructure for pedestrian detection Pedestrians are not equipped with safety awareness devices
