چکیده
Rear-end traffic collision has been a crucial problem due to numerous injury even death and corresponding economic and social damage. In order to eliminate these threats, a large number of researchers have paid effort on this area, with timeconsuming artificial intelligence-inspired methods or mathematical method in strict assumptions. In this paper, we propose a VANET-based real-time rear-end collision warning algorithm (VERCWA), to carry on real-time traffic risk assessment and inform drivers collision warning message in appropriate time. Traffic risk is evaluated with the consideration of space headway of the preceding vehicle and following vehicle, current speed of the relevant vehicles, drivers’ behavior characteristics (i.e. perception-reaction time) in a real-time way. Experiments conducted show that our VERCWA can obtain better performance, compared with HONDA algorithm with the utilization of a public dataset in California.

A Monte Carlo Simulation of Chain Reaction Rear End Potential Collisions on Freeways
In recent research on modelling road collisions very little attention has been paid to rear-end chain reaction collisions, which is characterized by more than two vehicles involved in a collision at the same time. The core aim of the present research is to develop a methodology to estimate such potential collision probabilities based on a proactive perspective, where deceleration rate to avoid...
متن کاملA real-time warning system for rear-end collision based on random forest classifier
Rear-end collision warning system has a great role to enhance the driving safety. In this system some measures are used to estimate the dangers and the system warns drivers to be more cautious. The real-time processes should be executed in such system, to remain enough time and distance to avoid collision with the front vehicle. To this end, in this paper a new system is developed by using rand...

Collision warning systems offer a promising approach to mitigate rear-end collisions, but substantial uncertainty exists regarding the joint performance of the driver and the collision warning algorithms. A simple deterministic model of driver performance was used to examine kinematics-based and perceptual-based rear-end collision avoidance algorithms over a range of collision situations, algor...

Rear-end collisions account for almost 30% of automotive crashes. Rear-end collision avoidance systems (RECASs) may offer a promising approach to help drivers avoid these crashes. Two experiments performed using a high-fidelity motion-based driving simulator examined driver responses to evaluate the efficacy of a RECAS. The first experiment showed that early warnings helped distracted drivers r...
