摘要
为提高高速公路过江隧道入口段的行车安全性,以上海长江隧道为依托,通过调整匝道转弯半径、合流区到隧道口间距等局部线形参数建立不同驾驶模拟场景,并运用驾驶模拟实验的方法对行车安全风险进行研究。从纵向事故风险、横向事故风险及驾驶员负荷3个方面考虑,运用层次分析法建立高速公路过江隧道入口段行车安全风险评价体系和评价模型,并与驾驶员主观感受对比验证评价模型的有效性。评价模型的应用结果表明,不同局部线形设计的场景行车安全风险不同,当合流区到隧道口距离为350~425 m、匝道转弯半径为350~450 m时,行车安全风险指数较低,行车安全性更好。
In order to improve traffic safety in the entrance section of express cross-river tunnel,based on the Yangtze River Cross tunnel in Shanghai,this paper adjusts partial linear parameters such as the turning radius of the ramp,the distance from confluence zone to tunnel entrance and so on,to establish different driving simulation scenarios,and use driving simulation method to explore the traffic safety risks.Considering vertical risk,horizontal risk and driving load,analytic hierarchy process is used to establish a traffic safety risk evaluation system and an evaluation model,and the comparison with the drivers’subjective experience verifies the effectiveness of the evaluation model.The application results of the evaluation model show that different partial linear parameters have different traffic safety risks.When the distance from the confluence zone to tunnel entrance is 350~425 meters and the turning radius of ramp is 330~450 meters,the traffic safety risk index is lower and the traffic safety is better.
