StreetLight Speed Validation White Paper 

This mini white paper demonstrates data validation for three of StreetLight’s available Speed Metrics: 85th percentile speed, speed distribution, and hourly speed.

This is a “short and sweet” validation comparing StreetLight’s Speed Metric to publicly available speed data published by Washington State Department of Transportation (WSDOT) and the California Department of Transportation’s Performance Management System (PeMS).

Get the paper to learn more about how StreetLight’s 85th percentile speed and WSDOT’s reported speed have a strong correlation with an R² value of 0.91 and how both StreetLight’s speed data and PeMs have comparable hourly speeds during all times of the day, including peak AM and peak PM hours.
