【摘要】:為了緩解宏觀交通網(wǎng)絡(luò)擁堵區(qū)的擁堵狀況并降低機(jī)動車燃油消耗,首先依據(jù)路網(wǎng)狀態(tài)劃分的宏觀基本圖控制子區(qū),建立了擁堵區(qū)邊界車流平衡方程.其次將路網(wǎng)分為交叉口和路段兩類,根據(jù)宏觀基本圖參數(shù)建立了網(wǎng)絡(luò)能耗估計模型.再次以宏觀路網(wǎng)出行車輛完成率最高同時能耗最低建立了能耗節(jié)約擁堵區(qū)邊界雙目標(biāo)優(yōu)化控制模型.最后以實(shí)際城市道路網(wǎng)絡(luò)為測試對象,通過比較無區(qū)域邊界控制、擁堵區(qū)入口Bang-Bang邊界控制和本文提出的雙目標(biāo)優(yōu)化控制方案,仿真結(jié)果表明:1)在高峰時段,雙目標(biāo)優(yōu)化控制方法路網(wǎng)疏散能力比無區(qū)域邊界控制、Bang-Bang控制分別提高20.14%、2.1%,同時機(jī)動車燃油消耗分別降低43.14%、24.48%;2)本文提出的雙目標(biāo)優(yōu)化控制方法可有效改善擁堵區(qū)內(nèi)外交通密度的均衡性;3)宏觀路網(wǎng)擁堵區(qū)的邊界控制可有效降低高峰期間擁堵區(qū)的擁塞程度,提高整個路網(wǎng)的疏散能力.
[Abstract]:In order to alleviate the congestion in the macroscopic traffic network and reduce the fuel consumption of motor vehicles, first of all, according to the state of the road network, the macroscopic basic map is used to control the sub-area. The equilibrium equation of traffic flow at the boundary of congested area is established. Secondly, the road network is divided into two types: intersections and sections. The network energy consumption estimation model is established according to the parameters of the macroscopic basic diagram. Finally, the model of dual objective optimal control of the boundary of energy saving congestion zone is established with the highest completion rate and the lowest energy consumption of the macro road network. Finally, the actual situation of the network energy consumption estimation model is given. The urban road network was tested, By comparing the no-region boundary control, the Bang-Bang boundary control in congested area and the two-objective optimal control scheme proposed in this paper, the simulation results show that: 1) in the peak period. Two-objective optimal control method the evacuation capacity of road network is 20.14% higher than Bang-Bang control without regional boundary control, while the fuel consumption of motor vehicle is reduced by 43.14% 24.48%. 2) the dual objective optimization control method proposed in this paper can effectively improve diplomacy in congested area. The boundary control of the macroscopic network congestion zone can effectively reduce the congestion degree of the congestion area during the peak period. Improve the evacuation capacity of the entire network.
