The Crash Avoidance Metrics Partnership (CAMP) Vehicle Safety Communications Consortium (VSCC) comprised of BMW, DaimlerChrysler, Ford, GM, Nissan, Toyota, and Volkswagen, in partnership with USDOT, established the Vehicle Safety Communications (VSC) project to: estimate the potential benefits of communication-based vehicle safety applications and define their communications requirements; ensure that proposed DSRC communications protocols meet the needs of vehicle safety applications; investigate specific technical issues that may affect the ability of DSRC to support deployment of vehicle safety applications; and, estimate the deployment feasibility of communications-based vehicle safety applications. A comprehensive list of communications-based vehicle safety and non-safety application scenarios was compiled. More than 75 application scenarios were identified and analyzed resulting in 34 safety and 11 non-safety application scenario descriptions. Preliminary communications requirements were developed and an analysis of alternative wireless technologies was completed. Potential advantages of DSRC technology are the capability for 1) very low latency communications, and 2) transmission of broadcast messages. Each safety application scenario was further defined to include an initial estimate of potential safety benefits. Eight high potential benefit safety application scenarios were selected for further study: Traffic Signal Violation Warning, Curve Speed Warning, and Emergency Electronic Brake Lights, Pre-Crash Warning, Cooperative Forward Collision Warning, Left Turn Assistant, Lane Change Warning and Stop Sign Movement Assistance. These are representative of the range of communications requirements for vehicle safety applications. These scenarios were further analyzed and more detailed communications requirements were developed. Task 3 analysis suggests that DSRC is a potential enabler for a number of vehicle safety applications.
