2019 Urban Mobility Report Why is traffic congestion getting worse? The answer seems obvious, right? Every day there are more cars on our roadways, lining up bumper to bumper and inching their way toward various destinations.

Texas’ strong economy has generated unprecedented population growth. According to the US Census Bureau, Texas adds approximately 1,100 people daily and that means more cars on Texas roadways. According to the 2019 Urban Mobility Report, “The United States added 1.9 million jobs from 2016 to 2017 — slower growth than the 2.3 million-plus growth in four of the five previous years, but more than enough to exacerbate the nation’s traffic woes. The result is that the average freeway traveler has to allow almost twice the expected trip duration to ensure dependable arrival for time-sensitive things like medical appointments, daycare pickup, and airline flights. Instead of the 20 minutes needed in light traffic, it’s best to plan a 34-minute trip. Furthermore,

  • the number of hours per commuter lost to traffic delay has nearly tripled, climbing to 54 hours a year;
  • the annual cost of that delay per commuter has nearly doubled, to $1,080;
  • the nationwide cost of gridlock has grown more than tenfold, to $179 billion a year; and
  • the amount of fuel wasted in stalled traffic has more than tripled, to 3.3 billion gallons a year.

Austin, Dallas, Fort Worth, Houston and San Antonio represent more than 65 percent of the Texas population. It is estimated by 2050 these metropolitan areas may comprise nearly 74 percent of the state population. They’re also home to 92 of the “Top 100” most congested roadway segments in the state.
