基于线段模型的高速公路安全与流量关系研究

Relationships Between Security and Flow in Highway Based on Linear Model

高速公路上的车辆行驶速度快,因此保证高速公路上车辆的行驶安全至关重要。通过线段模型分析了高速公路安全与车流量之间的关系,确定了高速公路在轻载与重载中的运行性能标准,把超车过程抽象化,即将车视为质点,把车道视为一条线段,当后一质点每次超越前一质点时,记录并累加求和来替代超车。在上述指导方法下,引入车流量分析车流量与安全的关系,最后引入智能交通概念,对车流量与安全的关系进行深入分析。

Vehicles always travel at high speed on the highway, thus ensuring driving safety is critical. This paper analyzes the relationship between highway safety and traffic flow through the line model. The highway running performance standards in light load and heavy load are identified, the process of overtaking is abstracted, in the abstraction, cars are deemed to points, driveway is regarded as a line, when the latter car overtakes the former, it will be recorded as overtaking with the time counted. On the basis of above method, this paper puts vehicle flow into the model to analyzes the relationship between security and flow, then introduces intelligent transportation systems to make a deeper analysis of the relationship between security and flow.
