Overview

Traffic count data for 4.5 million miles of roadway

StreetLight Metrics cover nearly every road in the U.S. and Canada, providing traffic estimates for multiple road segment types, including highways, low-volume, and recently developed roads. StreetLight’s Metrics include: AADT (Annual Average Daily Traffic), AAHT (Annual Average Hourly Traffic), MADT (Monthly Average Daily Traffic), and more. 

 Validation

• StreetLight AADT data is validated with nearly 3,000+ permanent counter data points across the U.S. and 2,500+ permanent counter data points across Canada.

• R2 of .98 for the U.S. and R2 of .97  for Canada.

• StreetLight’s AADT values correlate closely with AADT values from permanent counters.

StreetLight InSight® Use cases 

• Safety - Overlay traffic counts with crash data to identify locations with the highest crash exposure to prioritize where to invest in safety initiatives.

• Monitor VMT -  Understand how the drop or rise in vehicle miles traveled can affect transportation planning, inform  estimations for gas tax shortfalls, or drive pollution changes. 

• Before and After Studies - Get traffic activity across time to analyze the impact of infrastructure changes

• Site Selection - Select the best corner at an intersection for your next store or gas station with on-demand turning movement counts and directional traffic volumes.

• Corridor Studies - Utilize ‘activity heatmaps’ to determine the most traveled road and neighborhoods in metro areas and regions.

• Equity - Analyze pedestrian, bicycle, and transit activity layered with demographics to ensure equitable access to transportation.

• Congestion Studies - View macro and micro-level traffic activity for all hours of the day layered with speed, demographics, vehicle hours of delay, and trip purpose to diagnose congestion regions and plan for mitigation strategies.

• Freight Studies - Determine the economic activity in areas near warehouses and ports by analyzing trips generated by commercial trucks.
