Abstract:
Owing to the rapid development in urbanization and automotive industry, the existing fix period traffic lights has longer been an optimal solution for modern traffic flow control. Dedicated Short Range Communication (DSRC) is an advanced protocol for inter-vehicular communication, which has good stability and has been widely used in Electronic Toll Collection(ETC) . This paper proposes an intelligent traffic lights control system based on DSRC to optimal the traffic flow within acceptable computational effort and cost for the OBU has a high rate of assembly. This paper firstly provide a detailed description for the system configuration and control strategy of the whole system. The proposed system is consisted with Roadside Unit(RSU), On-board Unit(OBU) and data processor. RSU collected the traffic information by OBU through wireless information and send to data processor. Secondly, the relationship between RSU and OBU is modeled and simulated to find the optimal parameters and settings software for the system. Thirdly, In order to verify the system in improving the bearing capacity of the traffic network and ease traffic pressure, we establish traffic flow model and carriy on the simulation.According to the simulation with the traffic flow model, comparing with the traditional traffic lights control system, the proposed system could increase the rate of traffic. The main contributions of this work are: 1. A novel intelligent traffic lights system is proposed. 2.The optimal parameters and settings of the software system is obtained via model-based analysis. 3.The feasibility of the proposed system is validated via simulation using specific traffic flow model.
