摘要

Two classes of detectors are compared for suitability of use for dilemma zone protection in thisrnchapter: the wide area detector (WAD) and the point detector. WADs provide the ability tornsimultaneously monitor the passage of each vehicle within a wide area and selectively influencernsignal phase timings based upon operational objectives related to measurements such as position,rnspeed, and count. Point detectors are usually loop detectors that influence signal phase timingsrnbased upon the presence of a vehicle at a fixed location. Point detectors are ubiquitouslyrndeployed for volume density operations, detection of congested traffic, and dilemma zonernprotection. In this paper both detector types are examined in relation to dilemma zone protection.rnThe results of this paper show a significant potential improvement in safety and efficiency ofrnoperation of isolated intersection by using an reliable WAD as dilemma zone detector. Thernsecond part of the paper investigates the performance of a radar based wide area detectionrntechnology and in third part investigates the potential improvements that can be made to thernexisting technology by using additional information from camera sensors.
