A Study on Low-Overhead Collision Warning Scheme using Vehicle-to-Vehicle Communications

Cooperative Intersection Collision - Warning System Based on Vehicle-to-Vehicle Communication

Intersection-collision warning systems use vehicle-to-infrastructure communication to avoid accidents at urban intersections. However, they are costly because additional roadside infrastructure must be installed, and they suffer from problems related to real-time information delivery. In this paper, an intersection-collision warning system based on vehicle-to-vehicle communication is proposed i...

The Front Vehicle Distance and Time to Collision Warning System

The front vehicle detection and alarm system proposed by this article can be applied to forward collision warning (FCW), forward distance estimation (FDE), and time to collision (TTC) estimation. Using the CCD camera to capture the road image in front for the image processing algorism, the image processing algorism is the key point which decides the accuracy and reliability of vehicle safety sy...

Prometheus: Vehicle to Vehicle Communications

Ray-tracing for Vehicle-to-vehicle Communications

A comprehensive model of the transmission channel between moving vehicles in realistic environments is presented in this paper. The approach consists of tree major parts: the modelling of the road traffic, the modelling of the environment adjacent to the road and the actual modelling of the wave propagation between the vehicles. A ray-tracing approach is used for the wave propagation, which all...

Weather-adapted Vehicle Detection for Forward Collision Warning System

A preceding vehicle detection method for forward collision warning system is proposed. The proposed method utilizes the horizontal and vertical edges instead of underneath shadow to detect preceding vehicles without being influenced by variant weather conditions. We first extract horizontal edges and then check the vertical edges above horizontal edges to confirm the location of a horizontal ed...
