JMT Honored for Development of Traffic Performance Metrics
February 8, 2013Location: Richmond, Virginia
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
