One of the goals of traffic safety in cities and between cities is to increase compliance with Traffic Regulations. For this purpose, the French Ministry of Transportation decided to set up an automated traffic enforcement program. This program currently focuses on several types of violations: speeding, spacing between vehicles, and traffic light and railway crossing. This article presents the main goals of the program and the expected challenges and characteristics of operations that have been implemented on various experimental sites. It then describes the technical architecture of the automated traffic enforcement systems being installed. Traffic regulation violations are on the rise in France. Violations of one or more regulations appear in a growing number of accidents. Today there is a very low probability of a driver being sanctioned; this fact has a direct influence on road safety. In this context the Interministerial Committee on Road Safety that met on October 25, 2000 decided to implement various measures to make traffic controls more efficient. A program for automating violation enforcement was started in 2001. The main goal of this program is to implement a certain number of experimental operations to encourage communication regarding scientific data. These data will be used to determine the concrete elements required for defining a framework to deploy these systems throughout the territory. Automated enforcement systems allow for continuous control without interception by Police. Violations are detected and recorded using fixed devices that are either integrated in the infrastructure or located on especially accident-prone sites.
