While the era of app-based ridehailing services, such as Uber and Lyft, has been credited with keeping more impaired drivers off the road, increasing job opportunities and offering new levels of convenience, it is also linked with more congestion and traffic deaths.

The arrival of ridehailing is associated with an increase of approximately 3 percent in the number of motor vehicle fatalities and fatal accidents, according to research from the University of Chicago Booth School of Business.

The researchers used the staggered roll-out dates from Uber and Lyft to review the eight quarters before and after ridehailing adoption in large U.S. cities from 2001 to 2016—analyzing traffic volume, transportation choices and accidents to arrive at their conclusion.

The documented increase in accidents appears to persist and even increase over time, and that rate has stayed steady through weekdays, weeknights, weekend days and weekend nights, according to John Barrios, assistant professor at Chicago Booth, and Yale V. Hochberg and Hanyi Yi, both of Rice University, in the working paper, The Cost of Convenience: Ridehailing and Traffic Fatalities.

Perspective - Number - Deaths - US - Level

For perspective, while in 2010 the number of roadway deaths in the U.S. stood at 32,885 (the lowest level since 1949), that number increased to more than 37,400 in 2016. The authors find that the introduction of ridehailing services in 2011 accounts for roughly 3 percent annual increase in auto deaths nationwide, or 987 people each year.
