3.7 SPaT Challenge - Intersection Approach Countdown - Overland Park

Description

Signal Phase and Timing (SPaT) data is supported in the connected vehicle environment through the deployment of roadside equiipment and onboard equipment in the vehicle to exchange signal timing data. The Eco-Approach and Departure at Signalized Intersections service package, upon which this project is based, uses wireless data communications sent from a connected vehicle roadside equipment (RSE) unit to connected vehicles to encourage "green" approaches to and departures from signalized intersections. The vehicle collects intersection geometry information and signal phase movement information using V2I communications and data from nearby vehicles using V2V communications. Upon receiving this information, the service performs calculations to provide speed advice to the driver, allowing the driver to adapt the vehicle's speed to pass the next traffic signal on green or to decelerate to a stop in the most eco-friendly manner. The service package also considers a vehicle's acceleration as it departs from a signalized intersection. In basic applications, this service provides a countdown to the signal change from green to yellow or red to green allowing the driver to adjust their vehicle speed to approach and depart the intersection in an optimal manner. The SPaT challenge is organized by the National Operations Center of Excellence to encourage DSRC device deployment in all states. This particular service is not the only one supported with this technology implementation so more applications can be added in the future using the same RSE and OBE implementations.
