Digital Alerting Helps Reduce Hard Braking by 80% in Purdue University Study
Work zones are some of the most dangerous places to be on the road. With narrow lanes, changing traffic patterns, changing speed limits and the presence of workers and equipment make being around the area a nightmare for workers and drivers alike. In 2019 alone, there were 115,000 work zone crashes, with 762 of those being fatal.
Purdue University recently completed a three-month study to measure the impact of queue warning trucks with digital alerts on hard-braking events. Their goal: to learn if warning drivers of work zones earlier with digital alerting could help reduce hard braking events on highways. Researchers used Queue Trucks, which are trucks deployed ahead of a work zone or crash incident to warn drivers of a hazard ahead. 19 Queue Trucks were equipped with Safety Cloud® digital alerting, which delivers digital alerts to approaching drivers through connected car systems and navigation apps such as Waze.
Across 12 weeks of research and 370 hours worth of observation of queues, the study found that queue trucks with digital alerting decreased hard braking events by 80%. The findings are similar to a 2013 University of Minnesota study, which found a 90% reduction in the likelihood of collision with an emergency vehicle when drivers received advance warning.
