INCIDENT DETECTION: SELECTION OF APPROPRIATE TECHNOLOGIES AND METHODOLOGIES

The paper investigates various technologies, logarithms and experiences used for incident detection. The most accurate level of incident alarm is sought. However, this does not necessarily need the same level of accuracy as the traffic parameters obtained from the detectors. Guidelines for ranges of change in traffic parameters are analysed in order to obtain a close to 100% incident alarm accuracy. The paper examines various technologies for incident detection in various roadway, traffic and environmental conditions. It recommends the integration of inductive loop detectors, and video cameras with rotation, tilt and zoom capabilities, which are connected to video image processing technology. The methodology and logical commands for an incident alarm are analysed. Language: en
