1.2.7.6–Provide Intersection Collision Avoidance Data (Pspec*)
This process shall provide collision avoidance data to vehicles that are approaching intersections served by the Manage Traffic function. The process shall use the data available from traffic sensors to determine any vehicle position conflict(s) that will arise if no action is taken. This process shall output data giving the direction from which the potential collision hazard will arise to the vehicle(s) that is(are) likely to receive the impact. This process shall, where possible, provide controls to the intersection controller and other nearby traffic control devices to avoid or minimize a crash.This Pspec is associated with the Roadway Subsystem*.
This Pspec is associated with the following Equipment Packages*:
