JMT Technology Group, together with Vanasse Hangen Brustlin, Inc. (VHB) and the University of Virginia, was recognized by the American Council of Engineering Companies (ACEC) of Virginia with a Merit Award for our Traffic Performance with INRIX Data pilot project for the Virginia Department of Transportation (VDOT).

VDOT is a state government organization dedicated to building, maintaining, and operating the state's roads, bridges and tunnels as well as funding initiatives for airports, seaports, rail, and public transportation systems. The agency has a critical need for quality performance measures to validate the need for improvements along its roadway network and to illustrate the impact of those improvements once implemented.

To this end, VDOT's Traffic Engineering Division (TED) contracted with JMT, in association with VHB and the University of Virginia, to develop performance metrics for five pilot corridors using historical travel time and speed data purchased from INRIX. This data was loaded into an Oracle database, and JMT developed methods and scripts to generate 9 performance metrics including Delay per Vehicle, Travel Time Index, Buffer Index, Planning Time Index, Percent On-Time Arrival, Total Delay, Congested Travel, Percent of Congested Travel and Misery Index. JMT's models aggregated the 5-minute data to annual values for each corridor and peak period using weighted analyses and statistical functions.

"The resulting report identified challenges and successes of the pilot study and is envisioned to be a prototype for stakeholders to refer to when developing metrics along additional commuter routes in Virginia," says Candice Ottley-Francois, CAPM, GISP, Analyst and Project Manager for the JMT Technology Group. "The report will help TED support its field operation staff involved with arterial and freeway management."

JMT Technology Group staff accepted the award at the ACEC's Engineering Excellence Awards Gala on Thursday, February 7, at the Jefferson Hotel in Richmond, VA.
