Abstract:

RTC’s Safer, Smarter, Faster smart technology traffic signal project utilized a cloud-based signal timing optimization system that supports transit signal priority (TSP) and enhances safety using artificial intelligence intersection analytics (AIA). The limits for Stage 1 pilot project encompass UMC hospital and downtown Las Vegas. Intersection analytics were deployed at 20 signalized intersections within the project limits. TSP was deployed along RTC Transit Route 206 at 17 signalized intersections along Charleston Boulevard and Casino Center Boulevard. This route often experiences lower on-time performance (OTP) scores than many other routes in the region, while being the 3rd highest passenger route.

Evaluation results showed weekday on-time performance improved by 3–6%, with delays reduced 7–13% and average savings of up to 78 seconds per trip. The AIA system achieved 92.2% accuracy for traffic detection and 97.6% precision in identifying red-light running and near-miss events.
