Approach to Avoid Collision between Two Vehicles in Intelligent Transportation System

Modern societies are increasingly confronted with the externalities of road traffic, such as congestion, accidents, consumption of scarce space, use of energy, and vehicle emissions. Many measures for controlling these externalities are currently under consideration by public authorities. These measures include incentives (e.g. charging for vehicle use), regulations (e.g. restricting lane access to specific groups, limiting speed under certain traffic conditions) and implementing new transport technologies to make the (road) transport system more ´intelligent´. The last category of measures is often labeled ´Intelligent Transportation Systems´ (ITS). Intelligent Transportation Systems refers to the use of information and communication technologies to collect and process (road) traffic data and to transmit it to transport users and/or operators. A variety of ´Intelligent Transportation Systems measures have been proposed and gradually implemented in order to improve the outcomes of the use of road infrastructure. Emphasis has been placed on traffic management and travel information measures, such as route guidance, ramp metering, speed regulation, flexible lane use, dynamic park and ride, and incident warning systems. The ´Intelligent Transportation Systems measures currently implemented within the field of traffic management and travel information appear to be effective.
