Road Traffic Accidents are a major cause of disability and death throughout the world. The control of intelligent vehicles in order to reduce human error and boost ease congestion is not accomplished solely by the aid of human resources. The present article is an attempt to introduce an intelligent control system based on RFID technology. By the help of RFID technology, vehicles are connected t...

This paper introduces a new intelligent method to generate vector maps from printed maps to provide a basis for GPS navigation. This new approach has been applied in our GIS-DMG (Digital Map Generation) software, which has four key steps: Map Layers Extraction, Road Network Digitalization, Map Geo-locating and Map Automatic Geo-adjusting, different from typical procedures. These four steps play...

We present a routing guidance approach that can be used in Intelligent Vehicle Highway Systems (IVHS). We consider IVHS consisting of automated highway systems on which intelligent vehicles organized in platoons drive to their destination, controlled by a hierarchical control framework. In this framework there are roadside controllers that provide speed and lane allocation instructions to the p...

Advanced Traveler [r~format~on Systems (ATIS) under the intelligent Vehicle Highway Systems (IVHS) context require efficient information retrieval and updating in a dynamic environment and at different geographical scales. Some problems in ATIS can be solved based on the functionalities provided by GIS systems. However, extra requirements such as realtime response are not readily met in existin...

This paper describes two projects applying computer vision to Intelligent Vehicle Highway Systems. The first project has resulted in the development of a system for monitoring traffic scenes using video information. The objective is to estimate traffic parameters such as flow rates, speeds and link travel times, as well as to detect quickly disruptive incidents such as stalled vehicles and acci...

This paper presents a fast lane changing algorithm for Intelligent Vehicle Highway Systems. The algorithm is based on the use of polinomial approximation of clothoids by using s-series. A new and accurate method that permits to obtain a polinomial with a low degree. Using this approximation we build an elementary path. We introduce a trigonometric approximation of elementary paths for the calcu...

For a given terrain to be traversed, it is computationally intensive to determine the fastest route between two points, and for defense or civilian emergency dispatching applications, computation time is critical. This paper reports the integration of a 24 x 25 random access array of digital processors which are programmed to model a given terrain and determine the fastest (lowest cost) path fr...
