| Research Abstract |
This research focuses on the travel time reliability and connected reliability for a high-grade highway network. Travel time reliability assessment model is developed for the variation of both demand and service level under uncertain environment of snow fall and traffic regulation in winter season. The framework considers the process that weather forecast affects implementation of traffic control and that the traffic control changes the travel speed. A multi hierarchical stochastic model under uncertainty of demand and service is developed. Two types of dependency of both traffic regulations and driving status between adjacent sections are considered. Travel time reliabilities are calculated and compared for several routes, and for normal and abnormal period under the given weather forecast pattern.
