Learn MoreThe 1st National Benchmark of Key Traffic Signal Performance Measures Using Connected Vehicle Data.
Using trillions of data points from connected vehicles and INRIX Signal Analytics, we analyzed all vehicle movements at over 210,000 signalized intersections across the US to provide a systemwide analysis of individual traffic signals on a national level.
The INRIX U.S. Signals Scorecard leveraged a week’s worth of data from October 2020, to provide the first national benchmarking of key traffic signal performance measures, like delay per vehicle (‘Level of Service’) and percent of vehicles arriving on green.
This report analyzed traffic signal performance on a National level, in every state and in the 25 largest MPOs/MPAs. Additionally, we ranked the 25 worst "urban intersections" nationwide based on average delay-per-vehicle.
