GENERIC VEHICLE SPEED MODELS BASED ON TRAFFIC SIMULATION: DEVELOPMENT AND APPLICATION

This paper summarizes the findings of a research project to develop new methods of estimating speeds for inclusion in the Highway Performance Monitoring System (HPMS) Analytical Process. The paper focuses on the effects of traffic conditions excluding incidents on daily average and excess fuel consumption. The chief contributions of the new speed models are the simplicity of application and their explicit accounting for the effects of queuing. Specific enhancements include: the inclusion of a queue discharge rate for freeways; use of newly defined uncongested flow speed functions; use of generic temporal distributions that account for peak spreading; and a final model form that allows incorporation of other factors that influence speed, such as grades and curves.
