Enhancing Safety, Reliability

Safety and reliability are crucial components of a multimodal transportation system serving millions of residents. North Texas’ size means it will always have areas that need to be addressed. One way planners are able to pinpoint problems is through the Congestion Management Process. 

Required for metropolitan areas with populations exceeding 200,000, the CMP outlines a series of steps to improve mobility throughout the region, beyond building expensive infrastructure. The latest CMP, updated in 2013, lists the 25 most congested corridor segments.

The map below shows where the corridors are located. During the evaluation process, planners examined alternate routes, available modal options, demand placed on the system and the reliability of the system. Scores were based on several transportation factors that influence congestion levels.

For example, each corridor was inventoried for the presence of parallel freeways, transit availability, level of traffic volume and severity of crash rates.  Understanding what areas are most congested helps planners prioritize where money can be spent most effectively.

Some of the corridors have improvements scheduled that will likely boost reliability for the driving public. Traffic signal retiming, part of the region’s congestion-mitigation strategy for years, is one way to improve these and other corridors throughout North Texas.

Various enhancements, including upgrades to signals and other infrastructure, help NCTCOG and its partners deliver a safer, more reliable system. FWTAhoroughfare Assessment and Regional Signal Retiming Programs have led to improvements at some 2,000 intersections since 2005, with 500 more to be finished in 2014. Improved and coordinated flow will help residents move more efficiently, enhance reliability for businesses and boost air quality. 

Another tool that helps NCTCOG determine priorities is the crash data received from TxDOT. The collected data helps to identify crash hotspots and assists in the development of improvement strategies for the locations.  

This is a five-year comparison of traffic fatalities in the Dallas- Fort area. NCTCOG offers training to help emergency personnel clear accidents and investigate incidents quickly, allowing the region’s transportation system to run more efficiently.

How the region responds to vehicle crashes is also important to the reliability of the transportation system. The graph shows a five-year comparison of fatality crashes in the 12-county metropolitan planning area provided by TxDOT.

In 2012, there was an increase in fatality crashes in North Texas, but they fell last year. Total crashes increased from 90,282 in 2012 to 97,895 in 2013. Greater attention to eliminating distracted driving is a priority.

To help first responders more efficiently address crashes that do occur, NCTCOG conducts Freeway Incident Management training. The goal of FIM training is to develop a coordinated response to traffic incidents that will build partnerships throughout the region, enhance safety for emergency personnel, reduce upstream crashes and improve air quality. Ultimately, more efficient clearing of crashes will improve the efficiency of the overall transportation system.

As the region grows, it is essential that strategies and programs to help alleviate gridlock are identified and implemented. NCTCOG, through the many elements of its safety program, is helping lead the way.  

The region’s 25 most congested corridor segments have been identified. Improvements are underway or planned in many corridors. Even in those areas that will have to wait, knowing where hotspots exist is crucial as planners and their transportation partners seek a complete picture of regional mobility.
