Basic Model of Traffic Flow with Discrete Disturber for Mountain Road
摘要
Abstract
Mountain roads, as a part of the road network, are playing a more and more important role in transportation system in China. However, the accident rate of mountain roads is substantially higher than those of other types of roads because of particular alignment, longitudinal slope and road conditions. Discrete disturber has been perplexing the users and the management departments as an important cause of mountain road accidents. Conventional traffic flow models are not suitable for mountain roads. Therefore, the traffic characteristics of mountain road traffic flow with discrete disturber is analyzed in this paper in order to propose a traffic flow model suitable for mountain roads. Then, Euler equation and Lagrange equation are used to build the basic mountain road traffic flow model influenced by discrete disturber. The research on traffic flow theory and safety of mountain road should be enriched, and the safety management of mountain road in China would be improved.关键词
