【摘要】：道路網(wǎng)絡(luò)容量是道路的一項(xiàng)重要指標(biāo)。它既是道路規(guī)劃設(shè)計(jì)所必須的基礎(chǔ)數(shù)據(jù),也是交通管理的重要參數(shù)之一。通過它可以獲得路網(wǎng)的飽和容量和潛在容量,還可以確定路網(wǎng)中瓶頸路段和路口。交通規(guī)劃不只是協(xié)調(diào)道路交通、軌道交通等城市交通問題,還要實(shí)現(xiàn)交通規(guī)劃與城市規(guī)劃的協(xié)調(diào),與社會(huì)經(jīng)濟(jì)發(fā)展的協(xié)調(diào)。而路網(wǎng)容量又是交通規(guī)劃問題中的一個(gè)重要方面。所以研究道路網(wǎng)絡(luò)容量對(duì)交通發(fā)展乃至社會(huì)發(fā)展都具有十分重要的意義。而隨著科技的進(jìn)步,越來越多的科技力量也滲入到交通系統(tǒng)中,比如先進(jìn)的出行者信息系統(tǒng)(Advanced Traveler Information System, ATIS)。由先進(jìn)的出行者信息系統(tǒng)所發(fā)布的出行信息影響著出行者們的路徑選擇行為,從而進(jìn)一步影響路網(wǎng)容量的變化。所以,研究出行信息對(duì)路網(wǎng)容量的影響是十分必要的。本文研究了現(xiàn)有的路網(wǎng)容量相關(guān)理論,討論了路網(wǎng)容量的定義和分類,以及影響路網(wǎng)容量的相關(guān)因素。然后介紹了現(xiàn)有的路網(wǎng)容量的基本的研究方法,并對(duì)各方法做了評(píng)價(jià)。同時(shí)也研究了ATIS的相關(guān)理論,并討論了ATIS對(duì)出行者路徑選擇行為有哪些正面和負(fù)面的影響。在以上的理論基礎(chǔ)上,運(yùn)用隨機(jī)用戶均衡的分配方法,分別建立了受ATIS信息質(zhì)量影響的路網(wǎng)儲(chǔ)備容量雙層規(guī)劃模型和受ATIS市場(chǎng)占有率影響的路網(wǎng)儲(chǔ)備容量雙層規(guī)劃模型。針對(duì)這兩個(gè)模型分別設(shè)計(jì)了基于連續(xù)平均法的求解算法。最后,通過兩個(gè)算例,分別驗(yàn)證了所建模型和設(shè)計(jì)算法的有效性,并分析了這兩個(gè)因素具體對(duì)路網(wǎng)容量產(chǎn)生了怎樣的影響。第一個(gè)模型的算例表明,一開始儲(chǔ)備容量隨著信息質(zhì)量參數(shù)的增加而減�。划�(dāng)信息質(zhì)量參數(shù)增加到一定程度后,隨著信息質(zhì)量的增加,儲(chǔ)備容量不再變化。第二個(gè)模型的算例表明,隨著ATIS市場(chǎng)滲透率的提升,儲(chǔ)備容量逐漸減小。合理的市場(chǎng)滲透率會(huì)使路段流量分布的較為均勻。但是必須指出的是,市場(chǎng)滲透率的增加對(duì)路段流量的改進(jìn)效果是邊際遞減的。
[Abstract]:The capacity of road network is an important index of road. It is not only the basic data necessary for road planning and design, but also one of the important parameters of traffic management. Through it, the saturated capacity and potential capacity of the network can be obtained, and the bottleneck sections and intersections in the road network can also be determined. Traffic planning is not only to coordinate urban traffic problems such as road traffic and rail transit, but also to coordinate traffic planning and urban planning, and to coordinate with social and economic development. Network capacity is an important aspect of traffic planning. So it is very important to study the capacity of road network for traffic development and even social development. With the progress of science and technology, more and more scientific and technological forces have infiltrated the transportation system, such as the advanced traveller information system (Advanced Traveler Information System, ATIS). The travel information released by the advanced traveler information system influences the route choice behavior of the travelers and further influences the change of the capacity of the road network. Therefore, it is necessary to study the effect of trip information on network capacity. This paper studies the existing theory of network capacity, discusses the definition and classification of network capacity, and the related factors affecting network capacity. Then the existing basic research methods of network capacity are introduced, and each method is evaluated. At the same time, we study the theory of ATIS, and discuss the positive and negative effects of ATIS on the routing behavior of travelers. On the basis of the above theory, using the method of stochastic user equilibrium distribution, the double-level programming model of road network reserve capacity affected by the quality of ATIS information and the double-level programming model of road network reserve capacity affected by ATIS market share are established, respectively. For these two models, the algorithm based on continuous averaging method is designed. Finally, through two examples, the validity of the model and the design algorithm are verified, and the influence of these two factors on the capacity of the road network is analyzed. The example of the first model shows that the initial reserve capacity decreases with the increase of the information quality parameter, and when the information quality parameter increases to a certain extent, the reserve capacity does not change with the increase of the information quality. The example of the second model shows that with the increase of ATIS market permeability, the reserve capacity decreases gradually. Reasonable market permeability will make the flow distribution of road section more uniform. However, it must be pointed out that the improved effect of increasing market permeability on road flow is marginal decline.
