盡管事實則是,這家鋼鐵集團就坐落在一個擁擠的城市,就象許多中國大型鋼鐵公司一樣。The engendering source of traffic volumes and their general influential factors have been presented, and the situation of nowadays highway transportation has been discussed. according to the introduction of traffic distribution theory and classical assignment method, analysis of traffic flow path selection among cities and that of special influential factors for traffic flow on toll highways, initial analysis to the forming mechanism of traffic volume on road sections has been made, and a probability model for path selection has been set up with the maximum - utility theory and disaggregating model. detailed analysis to impedances on road sections and their functions ( especially to three main composing factors of the impedances as cost of time, transport and toll and to the functional relations with traffic loads ) was made, at the same time, the relative cost calculating model was set up on the basis of the state - of - art achievements in both international and national researches
主要研究內容包括:交通量的產生根源及一般影響因素分析和當前公路運輸地位討論;從交通分配理論及經典配流方法著手,通過分析城市間交通流路徑選擇行為和收費公路路段交通量特殊影響因素,初步提出路段交通量的形成機理,並採用效用極大原理和非集結模型理論( disaggregationmodel ) ,建立用戶出行路徑選擇概率模型;對路段阻抗及路阻函數(尤其對行程時間費用、車輛營運費用和道路收費這三個構成路段阻抗的主要因素及其與交通負荷間的函數關系)進行較為詳盡的分析,並以現階段國內外較為先進的研究成果為依據建立相應的成本測算模型,其中,特別提出了兩種確定客貨車輛時間價值的分析方法;離散分析法和時間-費率轉換法,後者是在目前基礎調查、統計數據資料不夠齊全的現實下提出的一種確定道路系統內務車型時間價值的較為實用的新方法;對我國公路收費政策的背景和理論、實踐依據及費率的各種影響因素進行重點分析;從數學的角度證明合理費率的存在性,並以最優化理論為基礎,建立在普通收費公路和擁擠路段交通調控型收費公路兩種模式下合理費率的計算模型等。On the basis of the strategy of sustainable development, by our country ' s character of high dense population, high density use of urban land, tight concentrated form, single center tight configuration, paper applies coordinated idea of transport plan and land use plan, insists on the principle of public traffic development priority, seeks a high accessibility low demand model of land use and transport, bringi forward a new plan method of transit - oriented dev elopment to deal until connection between the effective use of urban land source and continual increasing demand of transport, thoroughly solves urban transport congest problem resulted by the imbalance of supply and demand of transport. also paper detailed analyzes and studies the concept, soit. general design principles, particularity of transit - oriented development region
在可持續發展戰略的指導思想基礎上,論文根據我國城市人口高度密集,城市土地高密度利用,以集中緊湊型為主的布局形態,單中心圈層式緊密結構的特點,運用交通規劃與土地利用規劃的協同觀念,堅持優先發展公共交通的原則,尋求高可達性、低交通需求的土地利用? ?交通系統發展模式,提出以公共交通為導向的城市土地利用形態的新的規劃方法,處理好有效利用城市土地資源與不斷增長交通需求之間的關系,從根本上解決交通供求關系不平衡而造成的城市交通擁擠問題,並對公共交通運輸導向開發區的概念、分類、設計總則、特質作了詳細分析研究。
