AASHT O SPaT Challe nge To challenge state and local public sector transportation Infrastructure Owners and Operators (IOOs) to deploy DSRC infrastructure with SPaT (and MAP) broadcasts in at least one corridor or network (approximately 20 signalized intersections) in each state by January 2020 20 int 20 ntersection ons in n 50 50 st states by by 2020 2020! 26 26 States Committed 450 450+ Signals Operating 3,800+ 00+ Signals Planned
Pilot De ployme nt Obje c tive s Primary goal: Develop back-end infrastructure, network components, and business processes to support broad vehicle to infrastructure applications that is broadcast-medium agnostic, scalable, and sustainable. Secondary goal: Begin broad installation of available roadside units and on-board units to facilitate applications that improve safety and mobility. Primary Application Spaces: Mobility Safety Freight Partnerships
Initial De ployme nt Phas hase 1: P Pilot ot – Active June une 2018 2018 • SR 141 (Peachtree) from SR 9 to I-285 • SR 8 (Ponce de Leon) from Peachtree to SR 42 • 54 traffic signals • 12 ramp meters • Signal Phasing and Timing (SPaT) • Red light warning • Pedestrian in signalized crosswalk (in development) • Phase termination/next signal phase • Green-band speed (Green light optimal speed)
Pha se 1 SPa T / MAP Applic a tions Safety for drivers – alerts of Red light warning inability to safely clear intersection Safety for drivers and pedestrians – Pedestrian in crosswalk turning vehicles have additional awareness of other users Efficiency for drivers – alert drivers Phase service remaining for safe intersection passage or efficient stopping Efficiency for drivers – inform Green speed for drivers of the optimal driving speed through coordinated signals to coordinated signals minimize stops ACTIVE RSUs IN METRO ATLANTA • SR 141 (Peachtree) – 39 intersections • SR 8 (Ponce de Leon) – 15 intersections • North Ave – 22 intersections (Renew)
