Bureau of Public Roads (BPR) Model

The Bureau of Public Roads (BPR) Model is a method used to estimate how traffic flow on a highway varies with changes in road capacity and congestion. It predicts travel times based on factors like road capacity, current traffic volume, and how much congestion increases as more vehicles are added. Essentially, it helps transportation planners assess how improvements or changes to roads will impact travel times and congestion levels, enabling more informed decisions for infrastructure development and traffic management.
