Assessing the Impact of a Local Community Subsidised Rideshare Programme on Road Traffic Injuries: A


A recent study led by PISC International Scholar and Internal Advisory Board Member David Humphreys, PhD, in collaboration with PISC International Scholar Michelle Degli Esposti, PhD, Senior Scholar Michelle Kondo, PhD, and Past Trainee Christopher Morrison, PhD, assessed the impact of the Evesham Saving Lives Program on rates of road traffic injury crashes. Between late 2015 and 2019, the program subsidized rideshare trips from bars and restaurants between the hours of 11:00 pm and 2:00 am in the Evesham and Voorhees townships of New Jersey. Humphreys et al. examined changes to road traffic injury rates using data from the New Jersey Department of Transportation with an ecological difference-in-difference approach.

Results indicated 18% fewer crashes overall. Specifically, night crashes between 11:00 pm and 4:49 am decreased by 38%, while morning crashes decreased by 11%. This study suggests that through providing efficient and inexpensive alternative night-time transportation, road traffic injuries can be prevented throughout suburban communities in the United States.
