基于賦色Petri網的公交優(yōu)先信號控制建模與分析
[Abstract]:With the development of urbanization, urban traffic problem is becoming more and more serious. Priority development of urban public transport is an effective way to solve traffic problems. In the case of limited road resources, bus signal priority is one of the methods to realize bus priority technology. It can effectively reduce intersections delay and improve the efficiency of bus operation. On the basis of fully considering the characteristics of signal control and bus priority of urban road intersection, this paper adopts two strategies: green light extension and red light early break, and uses colored Petri net (CPN) to model and analyze the bus priority signal control. The main content is: 1. The basic theory of bus priority signal control is introduced by analyzing the research results of bus priority control at home and abroad. Aiming at the phase characteristics of the signal lights at urban traffic intersections, a hierarchical model of signal control for intersections in urban roads is established using colored Petri net, and the signal control CPN model of four phases and two phases is established, respectively. A method of bus priority signal control based on CPN is proposed to solve the problem of bus traffic delay at intersections in urban roads and the inability of road resources and traffic signals to meet the priority rights of public transport vehicles. The method aims at ensuring the priority of bus traffic at intersections and realizes the control of bus priority signals by adopting two bus priority strategies: green light prolongation and red light early break. The four phase and two phase bus priority signal control CPN model. 3. In order to ensure the correctness and reliability of the CPN model for bus priority signal control, the state space of the CPN model is obtained by using the state space construction algorithm to simulate the state of the model. The basic properties of the model are verified by analyzing the state space. It shows that the model has good performance in solving the problem of bus priority signal control in urban roads and can achieve the purpose of bus priority.
