Abstract

This report opens up a new field of research called “Intelligent Transport Systems” which is an interactive system for the collection, processing and dissemination of information applied to the field of transportation an interactive system for the collection, processing and dissemination of information applied to the field of transportation. As we know, speed is a central issue in road safety. In fact, speed is involved in all accidents: no speed, no accidents. Speed has been found to be a major contributory factor in around 10% of all accidents and in around 30% of the fatal accidents. Both excess speed (exceeding the posted speed limit) and inappropriate speed (faster than the prevailing conditions allow) are important accident causation factors. This work tries to solve this problem by realizing an intelligent speed limit panel; which can determine the suitable speed for a safe driving according to the weather conditions and road characteristics. To do this we have used special kinds of sensors to collect information from the external environment then transmit it to the main unit where the system can decide the real time speed limit and display it for the drivers. Finally, we moved on to the testing part where we demonstrated the effectiveness of our solution and its future extension.
