ELECTROMAGNETIC COMPATIBILITY OF ROAD EQUIPMENT

One of the main activities of the DRIVE II project EMCATT (Electromagnetic Compatibility of Advanced Transport Telematics) concerns the electromagnetic compatibility (emissions and immunity) of dynamic roadside equipment that may be subject to malfunction and affect road safety. This paper considers the effects on inductive loops, in particular the French SIREDO system for road data collection. Some known failures and successful solutions are considered. In the absense of directives on the subject the project provides guidance on simple design rules for methods of installation and for the testing of traffic systems once installed.
