【摘要】：伴隨著城市化進(jìn)程的迅速發(fā)展,城市范圍不斷擴大,原來毗鄰城市的鄉(xiāng)村地區(qū)從以農(nóng)業(yè)為主的單一土地利用形式轉(zhuǎn)變?yōu)楣I(yè)、商業(yè)、住宅及其他用地的混合土地利用形式,同時城市基礎(chǔ)設(shè)施不斷豐富,形成了城鄉(xiāng)結(jié)合部這一區(qū)域。由于不同的土地利用形式對于接入道路的需求不同,因此城鄉(xiāng)結(jié)合部道路接入口的形式也十分多樣。國內(nèi)目前的設(shè)計規(guī)范和準(zhǔn)則對于道路接入口并未有系統(tǒng)性的規(guī)定,一定程度上導(dǎo)致了城鄉(xiāng)結(jié)合部道路接入口的無序建設(shè),降低了城鄉(xiāng)結(jié)合部道路的通行能力和安全性。本文以提升城鄉(xiāng)結(jié)合部道路的通行能力和安全性為目標(biāo),對城鄉(xiāng)結(jié)合部道路接入口的優(yōu)化布設(shè)方法進(jìn)行了研究。首先,通過查閱國內(nèi)外相關(guān)文獻(xiàn)以及實地調(diào)查獲取相關(guān)數(shù)據(jù),分析了城鄉(xiāng)結(jié)合部道路接入口處的車輛行駛特征以及沖突數(shù)據(jù),對城鄉(xiāng)結(jié)合部道路接入口進(jìn)行了分類,運用數(shù)理統(tǒng)計方法分析論證分類的合理性。然后,探討了各等級道路的接入口設(shè)置原則,研究了接入口之間以及接入口和交叉口之間的合理間距,提出了接入口的選位范圍。其次,研究了接入口的幾何設(shè)計,包括接入道路長度、接入口交通組織設(shè)計、接入口開口寬度和接入口處的轉(zhuǎn)彎半徑等,討論了在接入口設(shè)置密集的不利條件下布設(shè)接入口的方法。最后,結(jié)合實例給出了具體的改善措施,并運用VISSIM以及SSAM對改善措施進(jìn)行了論證,評估了改善措施的有效性。
[Abstract]:With the rapid development of urbanization, the urban scope is expanding, and the rural areas of adjacent cities have changed from a single form of land use dominated by agriculture to a mixed form of land use for industrial, commercial, residential and other land use.At the same time, the urban infrastructure continues to enrich, forming the urban-rural junction of this region.Because different land use forms have different demand for access roads, the access access forms of urban and rural areas are also very diverse.There is no systematic regulation on the road junction entrance in the current design code and criterion in China, which to some extent leads to the disorderly construction of the road junction entrance in the urban-rural joint area, and reduces the capacity and safety of the road in the urban-rural junction area.In order to improve the capacity and safety of the roads in the urban-rural junction, this paper studies the optimal layout method of the road entrance in the urban-rural junction.First of all, by consulting domestic and foreign relevant literature and field investigation to obtain the relevant data, analyzed the vehicle driving characteristics and conflict data at the road junction entrance of the urban and rural areas, and classified the road junction entrance of the urban and rural areas.The rationality of classification is proved by mathematical statistics.Then, the principle of connecting entrance is discussed, the reasonable distance between entrance and intersection is studied, and the selection range of entrance is put forward.Secondly, the geometric design of the entrance is studied, including the length of the access road, the traffic organization design of the entrance, the width of the opening and the turning radius of the entrance.This paper discusses the method of arranging the connection entrance under the unfavorable condition of dense connection entrance.Finally, the concrete improvement measures are given with examples, and the improvement measures are demonstrated by VISSIM and SSAM, and the effectiveness of the improvement measures is evaluated.
