Study on Calculation Methods of Intersection Unblocked Reliability based on the Random Arrival of Vehicle

摘要

The purpose of this paper is to study the calculation methods of intersection unblocked reliability based on the random arrival of vehicle Using theories of probability and traffic flow, with primary consideration of random arrival of vehicle, the unblocked threshold of the urban signal intersection is determined by analyzing the intersection vehicle arrival distribution model. Besides, the model is verified with simulation software Paramics. This study proposes a new approach for calculation method of unblocked reliability.
