Intersection Movement Assist and Lane Change Assist V2V Warnings with DSRC-based Basic Safety Messages

Dedicated Short Range Communication (DSRC) technology has the capability to dramatically improve safety in transportation not only for transit vehicle passengers as well as pedestrians. Connected Vehicles (CVs) utilize onboard units (OBUs) to communicate with other vehicles and/or infrastructure with Basic Safety Messages (BSMs). With such communication, the host vehicle (HV) can accurately determine the position, velocity, and heading direction of nearby remote vehicles (RV s). There exist many hazardous vehicle-to-vehicle (V2V) scenarios such as Blind Spot Warning (BSW) Front Collision Warning (FCW), Intersection Movement Assist (IMA), Lane Change Assist (LCA), etc. With inexpensive embedded onboard units in terms of power consumption, data generation, and financial cost in general, it is possible to overcome constraints presented by vehicles relying on sensors and radars e.g. poor visibility due to weather and objects. By extending previous work on the determination of relative angle with the RV, an innovative approach is proposed to address two V2V applications, IMA and LCA utilizing only BSMs. Furthermore, the aforementioned approach, along with different scenarios, is implemented and simulated using the CARLA simulator.
