Abstract
To investigate the effects of variable message signs on driving behaviors in urban areas, a logistic model of driving behaviors influenced by variable message signs has been established based on a ...
Highlights
Variable message signs (VMS) can relieve traffic congestion to some extent and improve road traffic efficiency by displaying real-time road traffic information and providing alternative routes
The independent sample T-test was separately conducted for the vehicle speeds of the West Wenchang Road and the North Yangzi River Road under different VMS states, and the null hypothesis H0 was that different VMS states have no significant influence on vehicle speed
Based on the results of T-test, it can be concluded that when the VMS was in operation, driving speed was significantly reduced as a result of reading VMS, which is consistent with the result from the logistic model in section ‘‘Establishment of logistic model and result analysis.’’ It has demonstrated that results of the logistic model are consistent with the field data
Summary
Variable message signs (VMS) can relieve traffic congestion to some extent and improve road traffic efficiency by displaying real-time road traffic information and providing alternative routes. Keywords Variable message signs, driving behavior, factors analysis, logistic model, independent sample T-test This article studies the decision-making behavior for drivers with different attributes when they are reading VMS information, investigates whether there is a significant difference in terms of vehicle speed variation under different VMS situations using T-test to verify the model’s analysis results.
