【摘要】：智能交通系統(tǒng)ITS（Intelligent TransportationSystem, ITS）是現(xiàn)階段交通運輸系統(tǒng)乃至未來交通運輸系統(tǒng)的主要研究領(lǐng)域和重要發(fā)展方向，而智能道路系統(tǒng)（IntelligentRoadway System, IRS）又是ITS的重要組成部分，一直是交通發(fā)達國家研究的熱點。基于該系統(tǒng)，本文提出了交叉口車路協(xié)同實驗系統(tǒng)框架、實現(xiàn)方法并進行了系統(tǒng)平臺的搭建。該實驗平臺主要實現(xiàn)的功能包括：仿真小車自動避碰，仿真小車定位，無線數(shù)據(jù)收發(fā)，交通信號燈配時控制等。進而通過對交叉口交通信號燈的配時控制，減少晚點公交車在交叉口的延誤，提高公交車的準點率。本文的主要工作如下： 1、設(shè)計了雙車道交叉口的道路模型，搭建雙車道交叉口硬件平臺，確定了仿真小車的運行路線。 2、規(guī)劃仿真小車的行駛路線，實現(xiàn)智能仿真小車在既定環(huán)路運行，，包括仿真小車運行的基本動作、仿真小車自動避碰、仿真小車定位及仿真小車通信的功能。 3、設(shè)計交通信號燈控制系統(tǒng)，包括交通信號燈硬件平臺的搭建，交通信號燈相位及配時控制，交通信號燈與仿真小車之間的無線通信。 4、設(shè)計了基于公交車輛優(yōu)先的交通信號燈配時方案，討論了當有少量公交車通過交叉口時的交通信號燈配時方案和有較多公交車排隊通過時交通信號燈的配時方案，后者利用模糊邏輯控制的方法調(diào)節(jié)交通信號燈的配時方案。
[Abstract]:ITS(Intelligent Transportation system (ITSs) is the main research field and important development direction of transportation system and transportation system in the future, and Intelligent Roadway system (IRS) is an important part of ITS. It has always been a hot research topic in developed countries. Based on this system, this paper puts forward the framework of intersection vehicle-road cooperative experimental system. The main functions of the experimental platform are as follows: automatic collision avoidance simulation vehicle positioning wireless data transceiver. Traffic lights timing control. Then through the intersection traffic lights timing control, reduce the delay of the late bus at the intersection, improve the bus punctuality rate. The main work of this paper is as follows:. 1. The road model of the two-lane intersection is designed, the hardware platform of the two-lane intersection is built, and the running route of the simulation vehicle is determined. 2. Planning the driving route of the simulation vehicle, realizing the function of intelligent simulation vehicle running in the fixed loop, including the basic movement of the simulation car, the automatic collision avoidance, the positioning of the simulation car and the communication function of the simulation vehicle. 3. The traffic signal control system is designed, including the construction of the traffic signal hardware platform, the phase and timing control of the traffic signal, and the wireless communication between the traffic signal light and the simulation vehicle. 4. The traffic signal timing scheme based on bus priority is designed. The traffic signal timing scheme when a small number of buses pass through the intersection and the traffic signal timing scheme when there are more buses queueing through the intersection are discussed. The latter uses the method of fuzzy logic control to adjust the timing scheme of traffic lights.
