干线公路无信号控制交叉口交通事故多发,严重影响干线公路网的安全性。从导致交叉口不安全的影响因素出发,提出交叉口设施规范偏离度的概念,并分别计算交叉口几何特征、交通标志、交通标线和照明设置的规范偏离度。在此基础上,考虑交通流处于理想运行状态和实际运行状态,分别建立交叉口的理想评价模型和修正模型,进而建立综合模型,对交叉口做出安全评价。另外,利用专家调查法和层次分析法确定各影响因素的权重,根据综合模型计算交叉口的潜在危险度,并据此将交叉口安全等级划分为A~D级。
榦線公路無信號控製交扠口交通事故多髮,嚴重影響榦線公路網的安全性。從導緻交扠口不安全的影響因素齣髮,提齣交扠口設施規範偏離度的概唸,併分彆計算交扠口幾何特徵、交通標誌、交通標線和照明設置的規範偏離度。在此基礎上,攷慮交通流處于理想運行狀態和實際運行狀態,分彆建立交扠口的理想評價模型和脩正模型,進而建立綜閤模型,對交扠口做齣安全評價。另外,利用專傢調查法和層次分析法確定各影響因素的權重,根據綜閤模型計算交扠口的潛在危險度,併據此將交扠口安全等級劃分為A~D級。

Most traffic accidents happen at intersections of arterial highways without signal control and seriously influence safety of arterial highways. Starting from influence factors causing unsafety of intersections, this paper proposes the concept of standard deviation of facilities at intersections, and calculates standard deviations of geometric features, traffic signs, traffic lines and lighting setup at intersections, respectively. On this basis, the paper considers ideal and actual running states of traffic flow, and establishes ideal evaluation model and correction model of intersections, and further establishes integrated model to make safety evaluation for intersections. In addition, the paper determines weights of all influence factors by means of expert investigation method and analytic hierarchy process, calculates potential degree of risk at intersections according to integrated model and divides safety classes of intersections into classes A~D accordingly.
