Upon initial deployment of V2X connected vehicle systems, the benefits are not readily available on day-one. Considering that the average survivability of vehicles in the United States is approximately 15 years [NHTSA 2006], the market penetration needed for the benefits associated with connected vehicle systems won’t be fully realized for some time. Even if all new vehicles are mandated to include such systems in addition to aftermarket devices, a disproportionate amount of non-connected vehicles to connected vehicles will continue to exist for some time. Since there will be very few connected vehicles deployed initially, the environment will be incomplete in terms of data available for connected vehicle applications.
To overcome this problem, it is proposed to use ranging sensors that are now becoming increasingly common in new vehicles. By accessing this sensor, relative distances and speeds of other vehicles can be determined. This information can then be packaged into a Basic Safety Message (BSM) and transmitted over-the-air (OTA) by a Generating Host Vehicle (GHV) for use by other connected vehicles or infrastructure applications. By utilizing ranging sensors and connected vehicle systems, early deployment benefits for both drivers and infrastructure are increased.
The proposed research project focuses on development of a BSM generating algorithm implemented to expedite the benefits of connected vehicle systems. If positive performance results are gained, the proof of concept can then be leveraged to support:
