【摘要】：近年來,隨著我國城市居民生活水平的提高,交通出行需求問題越來越突出,利用有限的土地資源建立完善的公共交通系統(tǒng)是解決這一需求問題的關鍵,而合理規(guī)劃常規(guī)地面公交線網(wǎng)更能實現(xiàn)城市土地資源的有效利用。可達性作為評價公共交通系統(tǒng)服務水平的一個重要指標,不僅可以用來評價公交線網(wǎng)結構布局現(xiàn)狀,還可以為更好地進一步優(yōu)化公交線網(wǎng)起到重要的現(xiàn)實意義。本文基于可達性理論基礎,將常規(guī)公交線網(wǎng)可達性定義為出行者通過常規(guī)地面公交從出發(fā)點到達目的地獲得的廣義綜合效用,并從該定義出發(fā),分析了出行者交通出行需求及常規(guī)公交線網(wǎng)可達性主要影響因素。根據(jù)出行者特性和常規(guī)公交出行特性,對居民常規(guī)公交出行乘車線路選擇行為進行研究分析,建立了包括出行者特性、出行時間、換乘次數(shù)、公交服務質量、公交線網(wǎng)連通性等變量的多元Logit模型。該模型以隨機效用理論為理論基礎,以離散選擇模型為框架結構。采用SP/RP組合調(diào)查法獲取模型所需數(shù)據(jù),然后用SPSS統(tǒng)計軟件處理調(diào)查數(shù)據(jù),對多元Logit模型中的未知參數(shù)進行標定和驗證,最后得出文中所建模型能夠較為精確地對居民常規(guī)公交出行決策行為進行描述,并適用于城市常規(guī)公交線網(wǎng)可達性評價。
[Abstract]:In recent years, with the improvement of living standards of urban residents in China, the problem of transportation travel demand is more and more prominent. The key to solve this problem is to use limited land resources to establish a perfect public transportation system. The rational planning of conventional ground transit network can realize the effective utilization of urban land resources. As an important index to evaluate the service level of public transportation system, reachability can not only be used to evaluate the present situation of bus network structure, but also play an important practical significance for better optimization of public transport network. Based on the theory of reachability, this paper defines the reachability of conventional public transit network as the generalized comprehensive utility that travelers get from the starting point to the destination through the conventional ground transit, and proceed from this definition. The main influencing factors of travelers' travel demand and the accessibility of conventional bus network are analyzed. According to the characteristics of travelers and regular public transportation, this paper studies and analyzes the behavior of residents' choice of bus route, and establishes the characteristics of travelers, travel time, transfer times, and the quality of public transport service. Multivariate Logit model of bus network connectivity and other variables. The model is based on the stochastic utility theory and the discrete selection model as the frame structure. The data needed by the model are obtained by SP/RP combined survey method, and then processed by the SPSS statistical software, and the unknown parameters in the multivariate Logit model are calibrated and verified. Finally, it is concluded that the model can accurately describe the decision-making behavior of residents' conventional public transport travel, and can be used to evaluate the accessibility of urban conventional transit network.
