FUTURE DEVELOPMENTS IN TRAFFIC MONITORING

The first part of the paper describes carriageway-based and other fixed point sensors used for the automatic detection of vehicles. There is a growing demand for portable systems which use video recordings. Unfortunately, the abstraction of data from these records remains tedious and expensive when semi automatic data abstraction techniques are adopted. Examples of both simple and sophisticated video analysis systems based on different automatic image processing techniques are discussed. As costs of typical microprocessors and other microelectronic devices continue to fall, their use will increase in the field of traffic information and control. This paper considers the development of driver information systems in which individual vehicles will transmit data to roadside units and in return receive route guidance and local information. Based on received information, the roadside unit may actuate control measures or warning signs and store any data necessary for monitoring purposes.
