A Review of Prediction Models on Operating Speed for Highways

摘要

The prediction of operating speed is one of the key problems used to evaluate highway safety at the design stage. The research status on prediction models of operating speed for highways is presented, which includes the prediction models related to the parameters of tangent, horizontal curve, vertical alignment and the combination of horizontal and vertical alignment. The existing problems such as the influencing factors of road characteristics, driver perception, data collection devices and vehicle type are discussed. Some research focuses and developing trends on the modeling of operating speed are presented including the driver's model on the basis of preview behavior, the vehicle dynamics simulation model and the model based on the driver-vehicle-road comprehensive consideration.
