【摘要】：隨著城市人口的迅猛增長,城市用地規(guī)模的逐漸擴(kuò)大,市區(qū)用地不斷向四周蔓延,城市居民出行的需求也不斷增加。在這種背景下,城市軌道交通容量大、環(huán)保、快捷的特性,提升了城市交通業(yè)的服務(wù)水平、改善了居民出行質(zhì)量和效率、有效減少了私家車出行數(shù)量、緩解了城市擁堵和污染情況,對節(jié)能減排、實(shí)現(xiàn)可持續(xù)發(fā)展具有現(xiàn)實(shí)意義。近年來,城市軌道交通建設(shè)在我國已進(jìn)入蓬勃發(fā)展的時期。城市軌道交通的建設(shè)受社會政治經(jīng)濟(jì)條件的制約,選擇適宜于城市規(guī)模和交通形態(tài)的線網(wǎng)規(guī)模一直是國內(nèi)外研究的重點(diǎn)。城市軌道交通的合理線網(wǎng)規(guī)模決定了其與城市地域、經(jīng)濟(jì)、人口和出行的平衡關(guān)系。本文首先介紹了城市軌道交通的技術(shù)經(jīng)濟(jì)特性和類型,然后對線網(wǎng)的類型和線網(wǎng)規(guī)劃的主要內(nèi)容做了梳理,最后考慮軌道交通與城市的協(xié)調(diào)發(fā)展,分析了人口和城市形態(tài)布局對城市軌道交通線網(wǎng)的影響。根據(jù)城市軌道交通規(guī)劃的目標(biāo)和分析指標(biāo),將線網(wǎng)長度作為分析線網(wǎng)合理性的重要標(biāo)準(zhǔn)。本文利用層次分析法,對影響軌道交通線網(wǎng)規(guī)模的因素進(jìn)行分析,得出影響線網(wǎng)規(guī)模的遞階層次結(jié)構(gòu)。并詳細(xì)分析了人口與城市軌道交通線網(wǎng)規(guī)模的關(guān)系。然后,利用神經(jīng)網(wǎng)絡(luò)獲得各因素的影響權(quán)重。基于影響因素層次分析中城區(qū)人口、城區(qū)面積、地區(qū)生產(chǎn)總值(GDP)三個可量化的指標(biāo),提出以下三種方法計(jì)算城市軌道交通線網(wǎng)合理規(guī)模：1、基于城區(qū)人口規(guī)模的出行需求法；2、基于城區(qū)面積的服務(wù)水平法；3、基于地區(qū)生產(chǎn)總值(GDP)的成本效益法。然后,結(jié)合神經(jīng)網(wǎng)絡(luò)得到的影響權(quán)重,得出兼顧城區(qū)人口、城區(qū)面積、地區(qū)生產(chǎn)總值(GDP)三個方面的城市軌道交通線網(wǎng)合理規(guī)模。利用本文得到的線網(wǎng)合理規(guī)模計(jì)算模型,具體分析內(nèi)江市城市軌道交通的合理線網(wǎng)規(guī)模,為內(nèi)江市城市軌道交通的建設(shè)者提供了較有價值的規(guī)劃意見。
[Abstract]:With the rapid growth of urban population, the scale of urban land is gradually expanding, the urban land is spreading to the surrounding area, and the demand for urban residents is increasing. In this context, the large capacity, environmental protection and fast characteristics of urban rail transit have improved the service level of urban transportation and improved the quality and efficiency of the residents' travel. In recent years, the construction of urban rail transit has entered a period of vigorous development in China. The construction of urban rail transit is restricted by social and political and economic conditions, and it is suitable for urban scale and traffic. The scale of line network has always been the focus of research at home and abroad. The rational line network size of urban rail transit determines its balance with urban area, economy, population and travel. This paper first introduces the technical and economic characteristics and types of urban rail transit, and then combs the types of line network and the main content of line network planning. Finally, considering the coordinated development of urban rail transit and city, the influence of population and urban layout on urban rail transit network is analyzed. According to the target and analysis index of urban rail transit planning, the length of line network is regarded as an important criterion for the rationality of line network analysis. The factors that affect the scale of the network scale are analyzed, and the relationship between the population and the urban rail transit network scale is analyzed in detail. Then, the influence weight of the factors is obtained by using the neural network. Based on the influence factor level analysis, three quantifiable indexes of urban population, urban area and GDP are proposed. The following three methods are given to calculate the reasonable scale of urban rail transit network: 1, the travel demand method based on urban population size; 2, service level based on urban area; 3, based on the cost-benefit method based on GDP. Then, combining with the weight of the response of the neural network, the urban population, urban area and regional population are obtained. The rational scale of urban rail transit network in three aspects (GDP) is used to analyze the reasonable scale of urban rail transit in Neijiang by using a reasonable scale model obtained in this paper, which provides a more valuable planning opinion for the builders of urban rail transit in Neijiang.
