Abstract

In this research, a model was developed for estimating the queue length of vehicles, based on occupancy time of each vehicle collected by loop detectors which were setup at the upstream of urban street, The estimation model suggested a method which minimizes architectural effects of the street, such as existence of pedestrian crossing, for future applications to the field. The estimation model suggested in this research was established based on real traffic data collected at upstream detectors in Kangnam subway station, Seoul, and the fomula of the model is based on MultiPolynomial equations. Consequence of the experiments showed that the model can adequately and in real-time mode mesure length of the queue which were constructed at the 80 to 90 meters away from the upstream detectors. The estimation accuracy of the model was verified in statistical analysis conducted by regression analysis and test results in real traffic situation.
