City of Carrollton Partners with NCTCOG for Signal Timing Improvements on Belt Line Road

Belt Line RoadThe City of Carrollton is partnering with the North Central Texas Council of Governments (NCTCOG) to reduce delays and vehicle emissions by retiming 16 traffic signals on Belt Line Road along a nearly 4-mile stretch from the southbound ramp of President George Bush Turnpike (PGBT) to Trend Drive, just west of Marsh Lane. 

The project is part of NCTCOG’s Regional Signal Retiming Program, an effort to reduce the number of stops at traffic signals throughout the DFW Metroplex, thus reducing an estimated 5 percent of regional vehicle emissions and resulting air pollution. NCTCOG selected the Belt Line Road corridor in Carrollton and Coppell for funding. 

Carrollton City Council approved the agreement with NCTCOG at a November meeting. The total cost of the project is $89,600; the City is responsible for a local match of $15,680.

“This project will support the City Council’s vision of building a community that families and businesses want to call home by simultaneously increasing residents’ mobility and reducing their fuel usage and emissions,” Marc Guy, Assistant City Manager for Public Safety and Development Services, said. 

Over the past few years, the City has retimed several major corridors to improve traffic flow as Carrollton’s population and traffic volume continue to increase. These include Hebron Parkway from Marchant Boulevard/Crawford Drive to International Parkway; Rosemeade Parkway from Old Denton Road to Josey Lane; Frankford Road from the IH-35E ramp to Furneaux Lane; Keller Springs Road from Old Denton Road to Midway Road; Old Denton Road from Carrollton Parkway to Trinity Mills Road; Josey Lane from King Arthur Boulevard/Diamond Ridge Drive to Fyke Road; and Marsh Lane from Trinity Mills Road to Country Place Drive/Country Square Drive. The majority of these projects were part of earlier phases of NCTCOG’s Regional Signal Retiming Program. 

Through the 2011 retiming of Old Denton Road from Carrollton Parkway to Trinity Mills Road during Phase I of the program, NCTCOG estimates that travel time for the average of 24,272 drivers traveling through the corridor on a weekday was reduced by 672 hours. Daily user savings are estimated at $8,676.25 for weekdays with an estimated savings of 84 gallons. Volatile organic compounds (VOC) emissions are estimated to have been reduced by 459 grams per weekday. That corridor was again retimed through the second phase of the program in 2016, which resulted in reduced stops even with the reconstruction of the IH-35E corridor and Josey Lane at FM 544 at the time. 

Carrollton Police Chief Derick Miller said that the department has seen a decrease in backups and traffic accidents on Old Denton Road and other corridors that have been retimed. 

The Belt Line Road signal timing improvements are estimated to be completed by the end of 2019. The City’s Engineering Department will be working with a consultant contracted through NCTCOG to implement the improvements.
