Modeling Signalized Intersection Using Queueing Theory

چکیده
Modeling the traffic flow at signalized intersections has been discussed in many works [1][2][3][4]. Though streets and intersections and designed to be Ergodic, the traffic flow during busy hours is not necessarily Ergodic. In this paper, we modeled the traffic at intersection during busy hours by using M/G/1 model. And based on the collected data, we modeled a special service distribution pattern for the traffic lights. We showed that the intersection system is not Ergodic, which means during the busy hours, the traffic queueing length and waiting time will keep growing. At last, we gave two approaches to make the system Ergodic and decrease the average system size as well as the average waiting time. We discussed the improvements and the costs of the two approaches.

Modeling Multiple–Vehicle Property Damage Collisions in Urban Signalized Intersections
Development of disaggregate models for estimating different property damage collision type frequencies in urban intersections has rarely been studied, particularly in Iran. It seems very little research work being implemented for studying the effect factors on collision type frequency at intersections. The main objective of this paper is to develop suitable statistical models to predict types o...

Although much is known about the operation of signalized intersections, little or no empirical research has been conducted regarding bicycle capacity at these locations and the correspondent contributory factors. The purpose of this study is to accurately quantify the capacity of bikeway at signalized intersection through a fluid dispersion approach, and ultimately the lane group capacity. Usin...

This paper analyzes the interdependency between the dynamics of queues at isolated signalized intersections and the lane-changing behavior of vehicles approaching the intersection. A dynamic queuing model based on Markov Chain renewal process is combined with a lane-changing behavior model in order to simulate the vehicle distribution in time. We applied this simulation to a two-lane intersecti...
