Vehicle Collision Warning System and Algorithm at Intersection under Internet-Connected Vehicles Environment

In recent years, research on Intelligent Transportation System (ITS) was done to solve many traffic problems. Considering the problem of traffic safety at blind crossing, a vehicle collision warning system based on Internet-Connected Vehicles was proposed in order to prevent a vehicle collision before it occurs. Internet-Connected Vehicles plays an important role in realizing the next generation ITS. Under Internet-Connected Vehicles environment, the vehicles install communication equipments and can exchange their driving information, including their position, velocity, heading angle and so on. On this basis, physical and logical frameworks of the collision warning system were designed after analyzing the system function. Then time to collision (TTC) was introduced to judge the vehicle collision and a judgment algorithm was proposed based on inter-vehicle communication. Furthermore, time to avoidance (TTA) was introduced to be compared with TTC in order to define the severity of collision and the system could alert the driver according to the level of danger. Finally, the simulation was carried out and results proved that the warning algorithm of the system is effective to give the an driver alert.
