Various researches have shown those vehicles travelling at excessive speed are more likely to cause an accident. In UK, an estimated 1200 fatalities per year on the roads can be attributed to inappropriate vehicle speed. It is believed that if it were possible to control vehicle speed within the legally accepted limits, on the road, the number and severity of these fatalities would be greatly reduced. Therefore, there is a need to develop methods of externally or remotely controlling or adapting vehicle speed limits. One method of affecting the necessary speed limits would be through the development of intelligent remote speed control system that employs the technologies of IntelIigent Transport System that focuses on infrastructure - vehicle - infrastructure communication.There are existing Intelligent Transport Systems technologies that can be developed for speed control/adaption system.One such system is that based on the deployment of infrastructure-based beacons. These beacons transmit the speed limit signal to the approaching vehicle and control its speed by activating the in-vehicle speed limiter. Another alternative systems architecture to provide the same external speed control similar to the beacon based approach, is based on an autonomous architecture in which the vehicle would be aware of its location from a GPS-base navigation system. This is where the vehicle is aware of the speed limit tor that location tram an on board digital road map in which the speed limit tor each link in the network has been encoded. This GPS based system has a number of drawbacks, one of which is that it will be difficult to implement dynamic speed adaptation. However, the underlying theme is to communicate with the vehicle (send the speed signal). Various technologies like General Packet Radio Service (GPRS), Global System for Mobile Communications (GSM), Code Division Multiple Access (CDMA), Time division Multiple Access (TDMA), Bluetooth etc. can help in the road-vehicle communications. An intelligent methodology is needed to integrate the technologies, the driver and the vehicle in order to start to address some of the concerns of deploying the systems.This paper presents a brief description of the technologies and a new method of integrating the driver in the decision process of an Intelligent Speed Adaptation system für trucks. A 'chain-speed' adaptation model is described. An experimental truck with the speed control is also presented.
