【摘要】：隨著我國社會經(jīng)濟的高速發(fā)展，高速公路建設取得了巨大的進步。高速公路規(guī)劃作為高速公路建設的前期工作，為其科學發(fā)展提供了重要支撐。而其中交通量預測又是交通規(guī)劃的重要環(huán)節(jié)，直接影響著規(guī)劃的科學性。因此，對交通量預測進行研究有著十分重要的現(xiàn)實意義。 首先，本文對交通量研究的國內(nèi)外發(fā)展歷程進行了介紹，分析了當前存在的問題，明確了研究方向。其次，在對交通量變化規(guī)律和影響因素研究的基礎上，針對傳統(tǒng)四階段法適用性不強、忽略全局的弊端進行了改進。最后，依托鄧州至豫鄂省界高速公路項目，對交通量預測進行了實例研究。在交通調(diào)查與分析方面，利用“Foxpro軟件包”和“串并聯(lián)法則”對原始數(shù)據(jù)進行校核，并對綜合交通運輸進行分析；在社會經(jīng)濟預測方面，利用二次多項式法和三次平滑指數(shù)法進行經(jīng)濟預測，并進行了定性定量分析；在交通發(fā)生方面，利用未來彈性系數(shù)法計算了集中發(fā)生交通量；在交通分布方面，利用弗雷特法、重力模型和logit模型分別對正常交通量、誘增交通量和轉(zhuǎn)移進行預測，并匯總得到了未來特征年OD表；在交通分配方面，采用均衡模型對相關(guān)道路進行交通量分配，并對互通立交轉(zhuǎn)向交通流量進行了模擬，最后對未來交通量進行了分析。在交通量預測整個實例研究過程中利用TransCAD軟件并結(jié)合優(yōu)化方法進行，，提高了預測的科學性。 本文結(jié)合相關(guān)理論對傳統(tǒng)四階段法進行了優(yōu)化，并結(jié)合鄧州至豫鄂省界高速公路進行交通量預測進行了實例論證，為以后同類工程提供一定參考。
[Abstract]:With the rapid development of China's social economy, highway construction has made great progress. Highway planning, as a preliminary work of highway construction, provides important support for its scientific development. Among them, traffic volume prediction is an important link in traffic planning, which directly affects the scientific nature of the planning. Therefore, the study of traffic volume prediction has a very important practical significance. Firstly, this paper introduces the development of traffic volume research at home and abroad, analyzes the existing problems, and clarifies the research direction. Secondly, on the basis of the research on the law of traffic volume change and the influencing factors, the traditional four-stage method is improved because of its weak applicability and neglecting the whole situation. Finally, based on the highway project from Dengzhou to Henan and Hubei province, a case study on traffic volume prediction is carried out. In the aspect of traffic investigation and analysis, we use "Foxpro software package" and "series-parallel rule" to check the original data and analyze the comprehensive transportation. In the aspect of social economic prediction, the quadratic polynomial method and cubic smoothing index method are used to carry out economic prediction, and qualitative and quantitative analysis are carried out, and in terms of traffic occurrence, the volume of concentrated traffic is calculated by using the method of elasticity coefficient in the future. In terms of traffic distribution, Fret method, gravity model and logit model are used to predict the normal traffic volume, induced traffic volume and traffic transfer, and the OD table for the future characteristic year is obtained. In the aspect of traffic allocation, the traffic volume of relevant roads is allocated by using equilibrium model, and the traffic flow of interchanges is simulated. Finally, the traffic volume in the future is analyzed. In the whole research process of traffic volume prediction, the TransCAD software and the optimization method are used to improve the scientific nature of the prediction. In this paper, the traditional four-stage method is optimized based on the relevant theory, and the traffic volume prediction of the highway from Dengzhou to Henan and Hubei province is demonstrated by an example, which provides a certain reference for the similar projects in the future.
