System Capability Assessment of Cooperative Intersection Collision Avoidance System for Violations (CICAS-V)
This report describes the system capability assessment for the Cooperative Intersection Collision Avoidance System for Violations (CICAS-V) based on data collected from objective tests and a pilot test. The CICAS-V is a vehicle-to-infrastructure system that provides visual, audio, and haptic (brake pulse) warnings when a vehicle is in danger of violating a traffic signal or stop sign at an intersection. A series of objective tests were conducted at the Virginia Tech Transportation Institute. Each test was defined by an initial geometry, a set of validity constraints [such as the sufficient Global Positioning System (GPS) accuracy], and a set of pass/fail criteria. The test series investigated the ability to appropriately warn or not warn at various speeds, in appropriately discerned lanes, under dynamic lane changes, under changing signal conditions, and in the presence of multiple equipped intersections. A pilot test was run with nearly 100 naïve drivers on a two-hour prescribed course in the Blacksburg, VA area. During the pilot test, drivers were appropriately warned when in danger of violating an obscured stop sign and when intentionally distracted. An algorithm was found to produce occasional nuisance warnings and remedied. An erroneous lane location in a geographical intersection description and a de-synchronized set of roadside equipment also produced some nuisance warnings and were also remedied.
