摘要

在管理城市化地区的交通系统时,基础设施的变化并不总能解决交通问题。与此同时,在智能交通系统框架内实施的组织措施可能是有效的。为了做出行动和战略决策,有必要建立一个典型紧急情况的基础,之前已经在仿真模型上对它们进行了研究。为此,我们选择了一种微观模拟方法,它可以考虑到交通流的随机性。作为计算机实验的结果,我们得到了在给定时间的紧急情况发生在t形十字路口时参数变化的估计(车辆在各个方向上穿过十字路口的平均时间,平均速度)。所提议的方法的新颖之处在于有可能根据各种影响因素的价值来评估紧急情况发展的性质。

Using Simulation for Investigating Emergency Traffic Situations
When managing the transport system of an urbanized area, infrastructural changes cannot always solve transport problems. At the same time, organizational measures implemented within the framework of an intelligent transport system can be effective. To make operational and strategic decisions, it is necessary to form a base of typical emergency situations, having previously studied them on a simulation model. For this, we have chosen a micro-simulation method, which allows taking into account the stochastic nature of the traffic flow. As a result of a computer experiment, we have obtained estimates of changes in parameters (average time for a vehicle to cross an intersection in all directions, average speed) when emergencies of a given duration occur at a T-shaped intersection. The novelty of the proposed approach lies in the possibility of assessing the nature of the emergency situations' development for various values of influencing factors.
