| Abstract: |
| Process of optimizing coordinated control is divided into two stages. At the first stage, the study improves a robust optimal control model of single-point intersection to optimize cycle and split. At the second stage, the study combines all links with intersections of arterial road as a complete system, and applies cell transmission model to simulate traffic flow on urban signalized arterial road. We propose a coordinated control model based on the platform to optimize offset between adjacent intersections. Genetic algorithm is executed by MATLAB to solve the model. The performance evaluations show that the model not only effectively reduces average delay and stopping rate of vehicles on arterial road and largely enhances traffic capacity of arterial road, but also lowers the sensitivity of signal control for flow fluctuations. |
