地下环形隧道出入口交通延误影响因素研究

Study on Influencing Factors of Traffic Delay at Entrance and Exit of Underground Circular Tunnel

摘要:

为了分析地下环形隧道出入口交通延误的主要影响因素，提高出入口的通行效率，基于地下环形隧道出入口的特点，首先从人、车、路、环境，以及车库吸引率等方面建立地下环形隧道出入口交通延误影响因素体系，然后从系统的角度出发，利用决策与试验评价实验室（DEMATEL）模型对影响因素进行分析。结果表明：地下环形隧道出入口交通延误的主要影响因素是出入口坡度、出入口车道长度和地下车库吸引率，最易受到影响的是车辆速度和驾驶人的反映判断能力。研究成果可为提高地下环形隧道和地下车库的通达性，减小地下环形隧道出入口的交通延误提供一定的理论依据。

Abstract:

In order to analyze the main influencing factors of the traffic delay at the entrance and exit of the underground circular tunnel and improve the traffic efficiency of the entrance and exit, based on the characteristics of the entrance and exit of the underground circular tunnel, the influencing factor system of the traffic delay at the entrance and exit of the underground circular tunnel is established from the aspects of people, vehicles, roads, environment and the attraction rate of garage. Then from the perspective of the system, the influencing factors are analyzed by using the model of decision-making and trial evaluation laboratory (DEMATEL). The results show that the main influencing factors of the traffic delay at the entrance and exit of the underground circular tunnel are the slope of the entrance and exit, the length of the entrance and exit lane and the attraction rate of the underground garage. The most vulnerable factors are the vehicle speed and the driver's reflective judgment. The research effects can provide a certain theoretical basis for improving the accessibility of underground circular tunnel and underground garage, and reducing the traffic delay at the entrance and exit of underground circular tunnel.
