Dynamical route-planning for vehicles based on global traffic information and communication

In this paper, we propose an effective transport system using global information VICS and local information IVC. The VICS (vehicle information and communication system) which is one of the intelligent transport systems, has been developed to release the traffic jam. The VICS is able to give real-time global information to drivers and help drivers to find the fastest route. However, a spatial oscillation of traffic jam will happen, known as hunting phenomena. On the other hand, IVC (inter vehicle communication) is a developing technology which enables cars to give and receive various information by optical communication, millimeter electromagnetic waves and so on. We first investigate the relationship between hunting phenomena and the VICS user ratio, and then realize an effective transport system, in which each car selects a different route and communicate with others by IVC.
