【摘要】：為了研究施工區(qū)上游過(guò)渡段的行車風(fēng)險(xiǎn),保障施工區(qū)的行車安全,應(yīng)用Vissim仿真軟件模擬施工區(qū)交通流的運(yùn)行狀態(tài),分析過(guò)渡段長(zhǎng)度、交通量、行駛速度對(duì)施工區(qū)行車風(fēng)險(xiǎn)的影響;利用沖突率作為評(píng)價(jià)指標(biāo),將路段行車風(fēng)險(xiǎn)分為5個(gè)等級(jí),運(yùn)用模糊綜合評(píng)判理論進(jìn)行綜合評(píng)判。研究結(jié)果表明:過(guò)渡段長(zhǎng)度、交通量是影響施工區(qū)上游過(guò)渡段行車風(fēng)險(xiǎn)最主要的因素,影響程度超90%,因而合理控制過(guò)渡段長(zhǎng)度和交通量對(duì)降低施工區(qū)行車風(fēng)險(xiǎn)具有重要作用。
[Abstract]:In order to study the traffic risk of the upstream transition section of the construction area and ensure the traffic safety of the construction area, the Vissim simulation software is used to simulate the running state of the traffic flow in the construction area, and the length and the traffic volume of the transition section are analyzed. The influence of driving speed on driving risk in construction area; The conflict rate is used as the evaluation index, the traffic risk is divided into five grades, and the fuzzy comprehensive evaluation theory is used to evaluate the traffic risk. The results show that the length of the transition section and the traffic volume are the most important factors affecting the traffic risk in the upstream transitional section of the construction area, and the degree of influence exceeds 90%. Therefore, reasonable control of the length of the transition section and traffic volume plays an important role in reducing the traffic risk in the construction area.
