English (US)   Are You Feeling Congested?  -  Categories: Opinions, Transportation  -  @ 01:22:00 pm

"Dallas-Fort Worth traffic congestion is fifth-worst in the country and worst in Texas," according to reports from the North Central Texas Council of Governments.
 

Souce: Dr Tim Lomax, TTI Presentation
Congestion

Longtime residents of the Metroplex have witnessed traffic congestion increase dramatically since 1982 when congestion in Houston was three times higher. By 2005, DFW had risen above even Houston, to the "fifth-worst in the country." While the problem was worsening here fast, it was also rising across the state's other large metropolitan areas.
 
The Texas Transportation Institute at Texas A&M University keeps track of this information and conducts studies to address these types of problem. Dr Tim Lomax from the Institute presented this information to a joint meeting of the Dallas Regional Mobility Council and the Tarrant Regional Transportation Coalition. (PDF version of Dr Lomax's presentation below.)
 
More than presenting the extent of congestion in North Texas and information from across the state, Mr Lomax revealed the frustration and cost of congestion. In the DFW area, the average driver during the peak period of congestion wastes 58 hours per year, at a cost of $1050. Across the state that amounts to 360 million motorist hours, 250 million gallons of gas, and a price tag of $6.7 million.
 
Metroplex drivers found roads uncongested 86% of the time in 1982. By 2005 it had dropped to only 34%. Conversely, the extremely congested period had risen from 3% to 28%. For area drivers, at least 57% of the time they drive they will encounter heavy congestion or greater, wasting 152 million hours and 11 million gallons of gas. Time and fuel both considered, that is an annual cost of $2.75 billion. The average trip takes 35% longer than those free-flow periods. Checking the clock face, we experience congested traffic 7.6 hours each day.
 

There is no one reason for congestion …

  • Bottlenecks (40%)
  • Traffic incidents (25%)
  • Work zones (10%)
  • Bad Weather (15%)
  • Poor Signal Timing (5%)
  • Special Events/Other (5%)

and there is no one solution:

  • Accept some level of congestion
  • Diversify development patterns
  • Manage the construction process
  • Manage the demand
  • Improve system efficiency
  • Build more capacity

 
Congestion is expensive, it degrades our quality of life in time lost and the cleanness of our air, it makes planning area trips unpredictable, and its waste of energy resources contributes to our dependence on foreign governments in both energy purchases and foreign capitalization, governments that are oftentimes hostile to our interests.
 
We're not stuck in this conundrum. We can manage our way forward but it will take leadership (which we do have) and money (which we are working to acquire) and planning (where we are doing better).
 
The first problem is recognizing the challenge, the subject of this post. I'll address some of the next challenges in future posts.

I would like to see Garland become a better place to live. I want it to be more attractive and more beautiful and I want the residents to be safer, healther and happier. Does this mean that we need to give them the ability to drive non-stop from one end to the other at a high rate of speed? Probably not. Garland does not have a congestion proplem. If you need to get out of Garland fast than you have probably been up to no good.

These suggestions for mitigating traffic congestion are from what? the 1950's?

Accept some level of congestion - As a planner and leader this is like saying, "we suck and we can't be better and the sooner we accept this the sooner we can move on to face other issues."

Diversify development patterns - This one acutally makes sense, but this needs to be a larger bullet.

We need to diversify the types of transportation available in the metroplex. Bike path, bus routes, rail routes side-walks, etc.

Immgine if we made pedestrial by-ways that actually linked together. People could bicycle or walk or even make it from the bus-stop to home without choosing whether to march through someone's muddy grass or to risk their lives on busy streets.

When Katy trail in Dallas was constructed the property value of the buildings directly adjacent to the trail went up in value by an average of 20%. The trail easily paid for itself in additional property tax revenues.

Adminstrators are ignorant: My child has been scolded for bicycling to school. 3,000 lb SUVs are allowed to drive on school property but a child is not allowed to ride in the parking lot leading up to the bike rack. Make it safe for children to walk, bike, skate, or shuffle to school and soccer moms will no loger clog up the road in the morning.

Manage the construction process. Concentrate on the bottlenecks but also provide alternatives to bottlenecks.

Manage the demand. we need to stop grouping like-use together. When everyone starts and stops their activites at the same time they hit the road at the same time and this causes congestion.

Improve system efficiency - This is too large a concept to even touch.

Build more capacity - this is not the solution. With $4.00 a gallon gasoline, automobiles are not the right answer for our population. Consolidation and diversification are the only viable alternatives.

Todd, you are right on the money. We need LESS roads in North Texas, not more. We should be building bike trails, rail lines, etc. instead of roadways.
