【摘要】：為了便于信號(hào)控制策略的實(shí)施,針對(duì)路網(wǎng)中不同狀態(tài)的交叉口,考慮子區(qū)內(nèi)交叉口的同質(zhì)性和關(guān)聯(lián)性,提出了基于不同擁擠程度的路網(wǎng)動(dòng)態(tài)分區(qū)方法.首先考慮相鄰交叉口的交通關(guān)聯(lián)度和相似度,建立了路網(wǎng)動(dòng)態(tài)分區(qū)模型;然后結(jié)合譜圖理論設(shè)計(jì)了動(dòng)態(tài)分區(qū)算法,根據(jù)特征向量元素,對(duì)路段、交叉口的擁堵程度進(jìn)行劃分;最后提出了動(dòng)態(tài)子區(qū)劃分評(píng)價(jià)準(zhǔn)則.算例結(jié)果表明,本文提出的方法既能有效地保證相關(guān)性較強(qiáng)的交叉口劃入同一子區(qū),又使得各子區(qū)內(nèi)部路段的擁堵程度比較均衡,有利于各種不同擁擠程度的子區(qū)信號(hào)控制方案的選擇和實(shí)施,對(duì)于交通信號(hào)控制方案的設(shè)計(jì)有實(shí)際的指導(dǎo)意義.
[Abstract]:In order to facilitate the implementation of signal control strategy, considering the homogeneity and relevance of intersections in different states of road network, a dynamic partition method based on different congestion degree is proposed. Firstly, considering the traffic correlation and similarity of adjacent intersections, the dynamic partition model of road network is established, and then the dynamic partition algorithm is designed based on spectrum theory, and the congestion degree of road sections and intersections is divided according to the characteristic vector elements. Finally, the evaluation criterion of dynamic subregion division is proposed. The numerical results show that the proposed method can not only effectively ensure the intersections with strong correlation into the same sub-area, but also make the congestion degree of each sub-area more balanced. It is beneficial to the selection and implementation of various sub-area signal control schemes with different congestion levels and has practical guiding significance for the design of traffic signal control schemes.
