【摘要】：交通網(wǎng)絡(luò)是城市發(fā)展的命脈,高速發(fā)展的城市需要一個穩(wěn)定、高效的交通系統(tǒng)。然而,實際交通系統(tǒng)的不確定性,出行者在出行過程中因信息缺乏而做出錯誤決策都會導(dǎo)致路網(wǎng)運行效率的急劇下降。為此,本文研究了在先進的出行信息系統(tǒng)環(huán)境中,以一定行程時間可靠性為約束的方式分擔(dān)與交通分配組合模型。論文假定出行者對交通信息的獲取來自先進的出行者信息系統(tǒng)(ATIS),該系統(tǒng)通過提供準(zhǔn)確、高質(zhì)量的交通信息來輔助出行決策。論文首先分析了信息對出行決策的影響,根據(jù)出行者信息獲取能力的不同將其分為“有ATIS裝置”和“無ATIS裝置”兩類,基于兩類用戶對路徑行程時間的不同感知利用路網(wǎng)混合均衡理論建立了信息影響下的路徑選擇模型。進一步,論文分析了交通系統(tǒng)不確定性的來源,以隨機供給路網(wǎng)為研究對象,在均勻分布的路段容量假定下給出了路徑出行時間預(yù)算的計算模型。最后,論文在組合出行決策的層次選擇框架下,假定“有裝置”和“無裝置”用戶對路徑及方式的感知誤差均服從Gumbel分布,采用變分不等式技術(shù),以出行時間預(yù)算為路徑選擇準(zhǔn)則建立了信息影響下考慮一定行程時間可靠性約束的方式分擔(dān)與交通分配組合模型。該模型能同時考慮信息系統(tǒng)的信息質(zhì)量、用戶的可靠度需求以及不同出行方式的吸引力對路徑及方式選擇的影響。論文進一步證明了該組合模型解的等價性并給出了模型求解算法。論文用測試路網(wǎng)開展了仿真分析,驗證了模型和算法的有效性。
[Abstract]:Traffic network is the lifeblood of city development. A stable and efficient transportation system is needed for a city with rapid development. However, the uncertainty of the actual transportation system and the wrong decision made by the travelers in the travel process due to the lack of information will lead to a sharp decline in the efficiency of the road network operation. Therefore, in the advanced travel information system environment, the combined model of sharing and traffic assignment in a certain travel time reliability constraint is studied in this paper. The paper assumes that travelers' access to traffic information comes from the advanced traveller information system (ATIS), which assists in travel decision by providing accurate and high-quality traffic information. Firstly, the paper analyzes the influence of information on travel decision, and divides it into two types: "with ATIS device" and "without ATIS device" according to the different information acquisition ability of travelers. Based on two kinds of users' different perception of path travel time, a path selection model under the influence of information is established by using the road network mixed equilibrium theory. Furthermore, the paper analyzes the source of the uncertainty of the transportation system, taking the random supply road network as the research object, and gives the calculation model of the route travel time budget under the assumption of uniformly distributed section capacity. Finally, under the framework of hierarchical selection of combined trip decision, assuming that the perceived errors of both "with and without devices" users follow the Gumbel distribution, the variational inequality technique is used. Based on the route selection criterion of travel time budget, a combination model of mode sharing and traffic assignment with certain travel time reliability constraints under the influence of information is established. The model can take into account the information quality of the information system, the reliability requirements of users and the influence of different travel modes on the path and mode selection. This paper further proves the equivalence of the solution of the combined model and gives the algorithm of solving the model. The simulation analysis of the test network is carried out, and the validity of the model and algorithm is verified.
