Challenges

Heavy, unpredictable traffic rerouted through Grapevine because of accidents, construction and congestion on the many highways surrounding the city

Previous signal management

 Coordinated timing plan

Although fewer than 50,000 people live in Grapevine, more than 300,000 drivers pass through it each day on their way to and from the Dallas-Fort Worth International Airport. Freeway accidents, road construction, shopping centers and events in the area make traffic volume on Grapevine’s arterial corridors highly variable. In July 2010, the city started installing InSync at 52 intersections, representing 90% of the city’s signals. “We wanted a long-term solution rather than a short-term solution that would have to be redone every three to five years,” says Mike Pacelli, transportation manager. “InSync operates with the intention of always keeping vehicles moving. With traditional signal coordination, vehicles can wait at a red light and traffic gets backed up when no one is using the green light on the main street. InSync always keeps someone moving, and it does, therefore, make the intersections appear to be more effectively used and waste less time.”

Benefits

Daily Benefit Annual Benefit
Vehicle Hours of Travel
(reduction)
1126 hours 292,835 hours
Fuel Consumption
(decrease)
988 gallons 256,678 gallons
Stops
(eliminated)
116,654 stops 30,330,276 stops
Total Economic Benefit $31,028 $8,067,234

This independent data shows InSync dramatically reduced stops, travel time and delay on all three corridors at critical times of day. InSync reduced stops by up to 88% and travel time by as much as 45%. Given the heavy volume of vehicles using these corridors, tens of thousands of motorists are experiencing improved traffic flow and shorter travel times. Less stopping and waiting at red lights also reduces fuel consumption and emissions. The result is a positive economic and environmental benefit to the community of Grapevine, Texas.

One Way to Cut Rush-Hour Traffic (Bloomberg Businessweek)

Two years ago, the streets of Grapevine, Tex., like thousands of roads across America at rush hour, resembled a parking lot every afternoon. The town of 50,000 near Dallas/Fort Worth International Airport saw 300,000 outside vehicles pass through each day as drivers sought to avoid highway delays.

Suburb Modifies Traffic Signals to Improve Commutes

Although fewer than 50,000 people live in Grapevine, Texas, more than 300,000 drivers pass through it each day on their way to and from the Dallas-Fort Worth International Airport. Freeway accidents, road construction, shopping centers and events in the area make traffic volume on Grapevine’s arterial corridors highly variable. (…) To improve driving conditions, city engineers considered retiming the traffic signals but eventually decided instead to implement InSync adaptive traffic control from Lenexa, Kan.-based Rhythm Engineering.

Project Highlight

Deployed InSync in a 52-signal network, reducing congestion caused by traffic diverted from freeway incidents



We chose the InSync system for a combination of its cost, its ease of installation and most importantly, its optimization routine – how well it optimizes traffic in real-time. The InSync system is performing great. The travel times and the number of stops have improved dramatically.
