Waycare, a leading artificial intelligence (AI) traffic management and transit solutions provider, announced June 14 the results of a year-long program aimed at curbing traffic incidents on Southern Nevada roads.

The program included the collaboration of the Nevada Department of Public Safety (DPS) Highway Patrol (NHP) Division, the Regional Transportation Commission of Southern Nevada (RTC) and the Nevada Department of Transportation (NDOT).


The results showed an 18% reduction in primary crashes and a 43% reduction in the percentage of speeding drivers along key corridors on I-15 and US-95 in Southern Nevada. A cost-benefit analysis showed a return 16 times greater than the initial investment, and more than $3 million in economic benefit and savings.


The program, funded by the National Safety Council’s Road to Zero grant, was awarded to the agencies to expand the use of AI, intelligent transportation system (ITS) devices and strategic police positioning to decrease speed on high-risk roads. By implementing an innovative approach combining AI and predictive analytics, the program was able to strategically identify high-risk corridors and deploy dynamic preventative measures.


Waycare uses proprietary AI algorithms to identify specific corridors and times at a higher risk of crashes derived from existing local data sets.


Based on the analysis of Southern Nevada, the deployment focused on three key corridors along I-15 Northbound near Russell Road, US-95 Southbound near Jones Boulevard and I-15 Southbound near Lake Mead Boulevard.


NHP troopers were periodically positioned at strategic traffic management sites to increase driver caution and vigilance. In tandem, the RTC regularly activated dynamic messaging signs to reinforce speed limits and preemptively slow traffic.


“The Nevada DPS Highway Patrol’s priority is the safety on Nevada’s roadways. This program is one way we can work together with our partnering agencies to help prevent fatalities and serious injury crashes,” said Col. Anne Carpenter with the Nevada DPS Highway Patrol Division.


“The combination of emerging technologies together with the collaboration of...
