【摘要】：近年來,我國城鎮(zhèn)化建設和新農(nóng)村建快速發(fā)展,為了帶動農(nóng)村地區(qū)的經(jīng)濟發(fā)展,我國政府對農(nóng)村公路建設的投資力度不斷加大,農(nóng)村公路因此取得了巨大的發(fā)展。此外國家越來越重視農(nóng)業(yè)、農(nóng)村、農(nóng)民的相關問題,出臺了一系列的優(yōu)惠政策,農(nóng)村地區(qū)交通發(fā)展迅速,機動車保有量逐年上升。然而,我國在加快農(nóng)村公路建設的初期,過于重視數(shù)量,而忽略了交通安全問題,加上農(nóng)村地區(qū)交通不斷的發(fā)展,導致農(nóng)村公路的交通安全問題突出,交通事故頻頻發(fā)生。由于低流量農(nóng)村公路流量低,道路使用率低的原因,無法得到管理部門足夠的重視。并且其交通安全特征與其他高等級公路有所不同,現(xiàn)有的安全保障技術適用性較低。本文通過對低流量農(nóng)村公路的調(diào)查和對交通事故數(shù)據(jù)的統(tǒng)計,從事故類型、事故車輛車型、事故發(fā)生時間和事故發(fā)生時段四個方面分析了低流量農(nóng)村公路的交通事故特征,總結了目前低流量農(nóng)村公路安全保障存在的問題。同時從人、車輛、道路、環(huán)境四個方面系統(tǒng)地分析的了低流量農(nóng)村公路的交通特征,找出了與其他高等級公路不同的特點。在對低流量農(nóng)村公路交通安全分析的基礎上,結合低流量農(nóng)村公路交通安全改善資金缺乏、沒有適用的安保技術、超速嚴重的情況,提出了基于限速值修正的安全保障技術。建立了結合駕駛員行車識別距離、反應時間、車輛制動性能、道路情況的限速模型,并且在臨水臨崖路段、急彎路段、陡坡路段對限速模型進行了修正和應用�；谙匏俚睦砟羁偨Y了多種適用于低流量農(nóng)村公路的安保設施,為交通安全改善技術人員起到指導的作用。最后,根據(jù)農(nóng)村地區(qū)資金缺乏,需要保證選用的交通安保設施發(fā)揮最大的效果的要求,對選用的交通安保設施進行效益評價。對交通安保設施的成本構成和效益構成進行分析和量化,通過效益成本比進行經(jīng)濟性評價,來選擇交通安保設施。
[Abstract]:In recent years, the construction of urbanization and the construction of new rural areas have developed rapidly. In order to promote the economic development of rural areas, our government has continuously increased its investment in rural road construction. As a result, rural roads have made great progress. In addition, the state has paid more and more attention to the related problems of agriculture, rural areas and farmers, and issued a series of preferential policies. The traffic in rural areas has developed rapidly, and the number of motor vehicles has increased year by year. In the early stage of speeding up the rural highway construction, our country pays too much attention to the quantity, but neglects the traffic safety problem, plus the continuous development of the traffic in the rural area, which leads to the prominent traffic safety problem of the rural highway. Traffic accidents occur frequently. Because of the low flow of rural roads and the low utilization rate of roads, they can not get enough attention from the management departments, and their traffic safety characteristics are different from those of other high-grade highways. The applicability of the existing safety and security technology is relatively low. Through the investigation of the low-flow rural highway and the statistics of traffic accident data, this paper analyzes the type of accident, the vehicle type of the accident, the vehicle type of the accident, This paper analyzes the traffic accident characteristics of the low flow rural highway from four aspects: the time of the accident and the time period of the accident, and summarizes the problems existing in the safety and security of the low flow rural highway at present. At the same time, from the aspects of people, vehicles, roads, The traffic characteristics of low flow rural highway are systematically analyzed in four aspects of environment, and the different characteristics from other high grade highway are found. Based on the analysis of traffic safety of low flow rural highway, Combined with the lack of funds to improve the traffic safety of low-flow rural roads, the lack of suitable security techniques and the serious overspeed situation, the safety and security technology based on the correction of the speed limit value is put forward, and the identification distance and reaction time of the drivers are established. Vehicle braking performance, speed limit models for road conditions, and in the face of water near a cliff, a section of a sharp bend, The speed limit model is modified and applied in steep slope section. Based on the concept of speed limit, several kinds of security facilities suitable for low-flow rural highway are summarized, which can guide the technical personnel to improve traffic safety. Finally, In the light of the lack of funds in rural areas and the need to ensure that the selected traffic security facilities are used to maximize their effectiveness, to evaluate the benefits of the selected traffic security facilities... to analyse and quantify the cost and benefit components of the traffic security facilities, Through the economic evaluation of cost-benefit ratio, traffic security facilities are selected.
