Abstract Urban intersections are faced with complex congestion problems and centralized control system has many drawbacks. To solve this problem, a relatively simple local method - the maximum pressure (MP) strategy is studied. Meanwhile, simulation of proposed MP conducted. After analyzing results, it found that can realize adaptive change phase duration. The makes number throughput vehicles a...

Current capacity manuals do not allow comprehensively evaluating negative effects on lane caused by undisciplined vehicle movements and utilization, such as failure to obey distance rules, blockage roadside parking effect, formation of an extra using in the emergency lane, etc., which are mostly observed undeveloped developing countries. Irregularities traffic flow utilization result decreased ...

A traffic control problem can be formulated as a decision-making problem for a stochastic dynamic system. Optimal traffic signal settings at intersections can minimize the vehicle delay time or the queue length at a stop line. In this paper, a new adaptive control strategy for signalized intersections is developed and tested by simulation. The simulation results show significant improvement ove...

Average delay is perhaps the most commonly used measure for characterizing the performance of signalized intersections. Current methodologies for estimating the average delay rely on the use of models based on volumes and green times. In practice, it is challenging to develop such real-time measurements of delay, due to the difficulty of accurately measuring vehicle arrivals and departures. How...

The primary purpose of this study is to examine the models’ performance for estimating average delay experienced by the passing vehicles at signalized intersection network, and to improve the models’ performance for Intelligent Transportation Systems (ITS) application in terms of actuated signal operation. Two major problems affected the models’ performance have been defined by the empirical an...
