Samenvatting
This paper summarises the findings on current capabilities of detectors for traffic control from a research project for DfT. It then identifies where efforts to improve detectors should be concentrated. The detector technologies and purposes considered are: Infra-red pedestrian detectors for kerbside detection, both passive arrays and active technologies, microwave pedestrian detectors for on-crossing detection, image processing pedestrian detectors for kerbside detection, sub-surface pedestrian detection for kerbside detection, spread spectrum radar pedestrian detectors for both on-crossing and kerbside detection, microwave vehicle detectors for use with SCOOT and active infra-red detectors for use with SCOOT.
