Waycare’s predictive AI showed an 18 per cent reduction in primary crashes and a 43 per cent reduction in the percentage of speeding drivers along key corridors.
The results of a year-long programme aimed at curbing traffic incidents on Southern Nevada roads have been announced.
Funded by the National Safety Council’s Road to Zero grant, the programme was designed to expand the use of artificial intelligence (AI), intelligent transportation system (ITS) devices, and strategic police positioning to decrease speeding on high-risk roads.
The programme 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, which leveraged transit solutions provider Waycare’s predictive AI, showed an 18 per cent reduction in primary crashes and a 43 per cent 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 16x return on the initial investment and more than $3m in economic benefit and savings.
Waycare used 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.
“The use of AI-based insights helped identify potential target areas, allowing us to increase safety and plan for preventative actions in the future”
Nevada Highway Patrol (NHP) troopers were periodically positioned at strategic traffic management sites (STMS) to increase driver caution and vigilance. In tandem, the RTC regularly activated dynamic messaging signs (DMS) to reinforce speed limits and pre-emptively slow traffic.
“The combination of emerging technologies together with the collaboration of law enforcement has proven to be successful in enhancing safety, preserving capacity and effectively communicating with Southern Nevada drivers,” said MJ Maynard, chief executive officer, RTC.
“The use of AI-based insights helped identify potential target areas, allowing us to increase safety and plan for preventative actions in the future.”
In addition to safety benefits, the agencies report the programme resulted in economic savings of $3.993m as a result of preventing property damage, medical costs, productivity loss caused by travel delays, and other agency-incurred expenses due to road crashes.
“Waycare’s innovative programme has shown real promise in helping improve traffic safety across Southern Nevada,” added Kristina Swallow, director of NDOT.
“As NDOT continues to build wireless infrastructure throughout Nevada, programmes leveraging crowdsource technology such as Waycare may prove to be a cost-effective strategy in providing quick and proactive incident response.”
The RTC is the transit authority, transportation planning organisation, regional traffic management agency and administrator of Southern Nevada Strong, the regional planning effort for the Las Vegas valley. RTC’s vision is to provide a safe, convenient, and effective regional transportation system that enhances mobility and air quality for citizens and visitors.
