WHITE PAPER

# All Vehicles Aggregated GPS Volume Methodology and Validation

##### StreetLight provides a quick, easy, and cost-effective way to measure hourly or daily traffic averaged at the yearly, monthly, or user-defined time period without any setup or sensor requirement.

##### Transportation professionals can get access to segment-level vehicular metrics for the most recent data period to measure traffic trends, including volume. StreetLight's segment-level volume metrics, powered by Aggregated GPS (AGPS) data, support a wide variety of use cases, including corridor studies, safety & traffic calming studies, existing conditions reporting, and traffic management.

##### Download our white paper to learn:

- Details about the methodology, algorithm development, validation, and data sources
- Validation results for volume metrics broken down by road sizes
- How the model captures month-over-month time trends across seasons

##### "The correlation between estimated MADT and permanent counter MADT is very strong, as the best-fit lines have an R2 of 0.98 in 2022 and 0.97 in 2023."
