A RELATIONSHIP BETWEEN VEHICLE DETECTOR OCCUPANCY AND DELAY AT SIGNAL-CONTROLLED JUNCTIONS

A method is described of measuring system performance using vehicle occupancy data collected from inductive-loop vehicle detectors. It provides an effective replacement of the conventional numberplate survey. The factors involved are numerous and complex. The results presented here were obtained inter alia during the investigation of signal control strategies. It is believed that the conclusions lead to a useful and inexpensive method of comparing junction performance. At 3 junctions a linear relationship has been found between observed values of mean delay per vehicle and observed values of mean occupancy per vehicle per detector. This is subject to the proviso that there are enough vehicle detectors, appropriately placed in the traffic lanes approaching the junction. This conclusion is reinforced from a traffic simulation computer program. Proposals are given for detector layouts to enable comparisons to be made between various signal control strategies.
