【摘要】：隨著我國綜合國力的增強，人們生活水平的提高，汽車數(shù)量迅速增長。汽車給人們生活帶來便利的同時，也給我們帶來了新的問題——交通問題。我國現(xiàn)在大中城市正面臨著嚴峻的交通問題，能否高效合理地解決這些交通問題，直接關(guān)系到城市的長遠發(fā)展。一味地通過大規(guī)模的增加道路等基礎(chǔ)設(shè)施建設(shè)來解決交通問題，是不科學(xué)也是不現(xiàn)實的。通過綜合運用交通信號控制技術(shù)，對交通信號的配時進行優(yōu)化控制等措施，來提高現(xiàn)有道路通行能力是解決交通問題的有效辦法。城市干線道路是城市交通重要組成部分，有著不可替代的作用。因此，對城市干線交通信號聯(lián)動控制研究，是解決我國當(dāng)前各主要城市面臨交通問題的有效途徑之一。 本文以合肥市黃山路為研究對象,通過干線道路交叉口交通流波動特性分析，，診斷交叉口交通信號配時的合理性。在此基礎(chǔ)上，建立了以車輛總延誤最小為優(yōu)化目標(biāo)的干線交叉口交通信號配時優(yōu)化模型。交叉口的延誤由干線協(xié)調(diào)方向車輛延誤和支路方向車輛延誤兩部分組成，本模型綜合考慮了支路方向車輛延誤和支路方向左轉(zhuǎn)彎車輛對干線車隊的影響，避免了傳統(tǒng)綠波設(shè)計的不足。利用遺傳算法對干線各交叉口的交通信號進行優(yōu)化求解，通過控制系統(tǒng)周期時長、各交叉口的綠信比和相鄰交叉口間的相位差等參數(shù)獲得最佳優(yōu)化方案。最后將仿真優(yōu)化結(jié)果與當(dāng)前黃山路干線配時方案進行對比和分析，結(jié)果表明優(yōu)化后的配時方案可以明顯改善干線車輛的總延誤。
[Abstract]:With the enhancement of our country's comprehensive national strength and the improvement of people's living standard, the number of cars is increasing rapidly. Automobile brings convenience to people's life, at the same time, it also brings us a new problem-traffic problem. Nowadays, large and medium-sized cities in China are facing severe traffic problems. Whether we can solve these traffic problems efficiently and reasonably is directly related to the long-term development of cities. It is unscientific and unrealistic to blindly solve traffic problems by increasing road and other infrastructure construction on a large scale. It is an effective method to solve the traffic problem by synthetically applying the traffic signal control technology to optimize the traffic signal timing control and so on to improve the existing road capacity. As an important part of urban traffic, urban trunk roads play an irreplaceable role. Therefore, the study of traffic signal linkage control in urban trunk lines is one of the effective ways to solve the traffic problems faced by major cities in China. In this paper, Huangshan Road in Hefei City is taken as the research object, and the rationality of traffic signal timing at intersection is diagnosed by analyzing the fluctuation characteristics of traffic flow at the intersection of trunk road. On this basis, a traffic signal timing optimization model for trunk road intersection with the minimum vehicle delay as the optimization objective is established. The delay at the intersection is composed of two parts: the vehicle delay in the trunk line coordination direction and the vehicle delay in the branch direction. This model considers the influence of the traffic delay in the branch road direction and the left-turn vehicle in the branch road direction on the trunk line vehicle fleet. The shortage of traditional green wave design is avoided. Genetic algorithm is used to optimize the traffic signal of each intersection in the trunk line. The optimal scheme is obtained by controlling the system cycle time, the green signal ratio of each intersection and the phase difference between adjacent intersections. Finally, the simulation results are compared with the current Huangshan Road trunk line timing scheme. The results show that the optimized timing scheme can significantly improve the total vehicle delay.
