Research Highlights

Improving Accuracy and Precision of Pedestrian Volume Estimates Using Advanced Machine Learning Approaches

Sirisha Kothuri Banafsheh Rekabdar
Counts provide the foundation for measuring nonmotorized travel along a link or a network and are also useful for monitoring trends, planning new infrastructure, and for conducting safety, health, and economic analyses. Most agencies still use manual counting methods, however over the last decade, several automated technologies have been developed to count bicyclists and pedestrians. Due to cost and other resource considerations, permanent counts are still limited to small subsets of networks… Read More
