Introduction

Abstract

This research service compares the accuracy of traffic flow data provided by Inrix Inc. and by Traffic.com in three metropolitan areas -- Philadelphia, Pennsylvania; Providence, Rhode Island; and Washington, DC. Predicted travel times provided by these two services are compared to actual travel times recorded by "ground truth" test runs. The study also lists the metropolitan areas covered by Inrix and by Traffic.com. This study was originally prepared for Inrix and is released by Frost & Sullivan by approval of Inrix. The original study was completed in September 2006, and the Addendum was completed in October 2006.
