The Bureau of Public Roads (BPR) function is a widely used link cost function in
transportation planning because of its simple mathematical form, easily measurable field …

The link performance and capacity are important quantitative features in road link
performance assessment, and they play vital roles in many important transportation tasks …

Parameter calibration of the traffic assignment models is vital to travel demand analysis and
management. As an extension of the conventional traffic assignment, boundedly rational …

Cost flow functions are a central class of models in the transport field because they are an
essential ingredient of static user equilibrium traffic assignment and transport policy and …

The use of predictive models to investigate the performance of automated network
management (ANM) under multiple control strategies and given traffic demands will help …

Sag curves, road segments where the gradient changes from downwards to upwards,
generally reduce the roadway capacity and cause congestion. This results from a change in …

Recent advances in communication and computing technology have made travel time
measurements more available than ever before. In urban signalized arterials, travel times …

This study utilizes travel time data from a well-equipped Intelligent Transportation System
corridor to integrate travel time and traffic signal data with the goal of developing a volume …

Travel time is the main transportation system performance measure used by the planning
community to evaluate the impacts of traffic congestion on infrastructure investment projects …

This project focused on developing and evaluating methods for estimating demand volume
for oversaturated corridors. Measuring demand directly with vehicle sensors is not possible …
