【摘要】：高速公路運(yùn)輸業(yè)的快速發(fā)展促進(jìn)了經(jīng)濟(jì)的繁榮,但是經(jīng)濟(jì)發(fā)展所帶來的交通量的增長超出了高速公路規(guī)劃時的預(yù)測量,這使得高速公路提前破損和老化,行車服務(wù)水平降低,不能與快速增長的交通量相適應(yīng)。高速公路在運(yùn)營一定年限后,需要對路面進(jìn)行局部施工維護(hù),保證高速公路的使用質(zhì)量和服務(wù)水平。為了保障行車安全,降低事故危險系數(shù),保持高速公路的良好運(yùn)營環(huán)境,在運(yùn)營期間需要及時養(yǎng)護(hù)和維修高速公路,消除安全隱患,提高高速公路的抗災(zāi)害能力。高速公路上將會有更多的改擴(kuò)建施工區(qū)段,研究改擴(kuò)建施工區(qū)的相關(guān)問題,確保施工區(qū)交通安全,成為日益突出的首要工作。論文首先從施工區(qū)交通特性分析,研究高速公路交通各要素的特征,分析各個要素之間的相互影響,即交通流的特性。交通特性的分析是高速公路施工區(qū)交通安全管理與控制的基礎(chǔ)和科學(xué)依據(jù)。為保障高速公路的服務(wù)水平,對影響改擴(kuò)建施工區(qū)交通安全的因素進(jìn)行研究分析,使得高速公路在改擴(kuò)建工程施工過程中,既不全部封閉道路,又要滿足行車安全的需求,經(jīng)濟(jì)效益達(dá)到可觀的期望值。其次,研究合理設(shè)置施工區(qū)的長度,一方面盡量減少施工區(qū)對車輛通行能力的影響,減少交通隱患和交通事故;另一方面能夠綜合考慮有利于施工作業(yè),使施工成本穩(wěn)定在一個合理的區(qū)間。優(yōu)化的施工區(qū)長度達(dá)到誘導(dǎo)交通流的流向,降低施工區(qū)車輛擁堵的幾率,防止事故發(fā)生的目的。最后,采用多級模糊綜合評價法,選取評價指標(biāo),對指標(biāo)量化處理,確定指標(biāo)權(quán)重,建立施工區(qū)交通安全評價模型,結(jié)合工程實例對施工區(qū)交通安全進(jìn)行綜合評價并驗證評價模型的適用性。
[Abstract]:The rapid development of the expressway transportation industry has promoted the economic prosperity, but the growth of the traffic volume brought by the economic development has exceeded the forecast amount of the expressway planning, which makes the expressway damaged and aging ahead of time, and the driving service level is reduced. It can't keep pace with the rapid growth of traffic. After running for a certain number of years, the expressway needs to carry on the partial construction maintenance to ensure the use quality and the service level of the expressway. In order to ensure the driving safety, reduce the accident risk coefficient and maintain the good operating environment of the expressway, it is necessary to maintain and maintain the expressway in time during the operation, eliminate the hidden danger of safety, and improve the anti-disaster ability of the expressway. There will be more reconstruction and extension sections on the expressway. It is increasingly important to study the related problems of the reconstruction and extension construction area and to ensure the traffic safety in the construction area. Firstly, from the analysis of traffic characteristics in the construction area, this paper studies the characteristics of each element of expressway traffic, and analyzes the interaction between each element, that is, the characteristics of traffic flow. The analysis of traffic characteristics is the basis and scientific basis of traffic safety management and control in expressway construction area. In order to ensure the service level of the expressway, the factors affecting the traffic safety in the reconstruction and extension construction area are studied and analyzed, which makes the expressway not only close the road but also meet the requirements of the traffic safety during the construction process of the reconstruction and extension project. Economic benefits reach considerable expectations. Secondly, the reasonable setting of the length of the construction area is studied. On the one hand, the influence of the construction area on the capacity of the vehicle is reduced as far as possible, and the traffic hidden trouble and traffic accident can be reduced; on the other hand, the comprehensive consideration can be beneficial to the construction operation. Make the construction cost stable in a reasonable range. The optimized length of construction area can induce the flow of traffic, reduce the probability of traffic congestion and prevent accidents. Finally, the multilevel fuzzy comprehensive evaluation method is adopted, the evaluation index is selected, the quantification of the index is processed, the index weight is determined, and the traffic safety evaluation model of the construction area is established. Combined with engineering examples, the comprehensive evaluation of traffic safety in the construction area is carried out and the applicability of the evaluation model is verified.
