【摘要】：為實(shí)現(xiàn)干線協(xié)調(diào),提高運(yùn)行效率,基于線控系統(tǒng)中車流以波的形式到達(dá)的基本認(rèn)知,分析了相鄰交叉口車輛排隊(duì)的時(shí)空特性,指出了干線協(xié)調(diào)的內(nèi)在機(jī)理是當(dāng)車流到達(dá)隊(duì)尾位置時(shí)排隊(duì)完全消散。然后針對(duì)排隊(duì)的集結(jié)與消散建立了基于交通波的交叉口相位差模型。并鑒于干線各交叉口間的關(guān)聯(lián)性以及交通需求與供給關(guān)系,提出了對(duì)干線控制參數(shù)的優(yōu)化策略。最后選取青島市漓江路沿線交叉口進(jìn)行案例分析,驗(yàn)證相位差模型以及周期、相位相序、綠信比等優(yōu)化策略的可行性與實(shí)用性,結(jié)果表明該控制方法對(duì)車輛旅行時(shí)間、停車次數(shù)的優(yōu)化效果顯著。
[Abstract]:In order to realize the coordination of trunk lines and improve the running efficiency, based on the basic cognition of the arrival of the traffic flow in the form of wave in the line control system, the space-time characteristics of the vehicles queuing at the adjacent intersections are analyzed. It is pointed out that the inherent mechanism of trunk line coordination is that the queue dissipates completely when the traffic reaches the end of the queue. Then the phase difference model of intersection based on traffic wave is established for the assembly and dissipation of queue. In view of the relationship between the intersections and the relationship between traffic demand and supply, the optimization strategy of the main line control parameters is put forward. Finally, a case study of the intersection along Lijiang Road in Qingdao is carried out to verify the feasibility and practicability of the phase difference model and the optimization strategies such as period, phase sequence, green letter ratio, etc. The results show that the control method is effective for vehicle travel time. The optimization effect of parking times is remarkable.
