In Automated Highway Systems (AHS), vehicles are equipped with automatic control systems to govern the accelerating, steering and braking functions in order to maintain an appropriate speed and spacing with respect to the surrounding vehicles. One concept of AHS suggests the implementation of...

Mobile radio communications systems are attracting more and more attention since they provide a means for users on the move to exchange information with other stationary or mobile stations. The capability of communication on the move can support many services and create lots of applications. For...

This documentation and software provides a tool which enable a user to perform the following tasks regarding vehicle spacing:; calculate the minimum initial spacing between two vehicles, calculate the possibility and severity of collision between two vehicles, visualize the motion of the two...

This paper discusses the effects of collisions in vehicle-following operations, especially for short-spacing scenarios. The collision analysis is conducted with a two-dimensional simulation program by which the translational and rotational movements of vehicles can be fully represented. Also...

This research project investigates the behaviors of vehicles in collisions, especially when they are closely spaced. The study uses a two- dimensional simulation program, EDSMAC, which allows longitudinal and lateral movements as well as the yaw motion of vehicles. The simulation model...
