Research Highlights
Exploring the Use of Crowdsourced Data Sources for Pedestrian Count Estimations
Sirisha Kothuri Nathan McNeil , Kate Hyun , Stephen Mattingly
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. For safety analysis, they are critical in assessing the exposure to risk. Over the last decade, several automated technologies have been developed to count bicyclists and pedestrians. Despite advances in counting technology, cost and other considerations will continue to limit…

BACKGROUND
While non-separated on-street bicycle facilities have been used in the United States for many years, separated on-street bicycle facilities are becoming increasingly popular. Many state and local departments of transportation (DOTs) have recently installed such facilities to address safety concerns and promote bicycling. Numerous other DOTs are exploring the potential for additional facilities to improve and…
