• Abstract:
  The Texas Department of Transportation (TxDOT) was the administering agency for the Texas Traffic Light Synchronization (TLS) Grant Program III which was funded with Oil Overcharge funds made available by the Governor's Energy Office. The TLS Program was approved by the United States Department of Energy as part of a package of transportation-related programs with the objective of reducing energy consumption. TLS III resulted in a total expenditure of $1. 7 million in program funds and local matches for the optimization of traffic signal timing plans and the replacement of outdated signal controller equipment across the state. As stated previously, the program's objective was to reduce traffic congestion and facilitate the flow of traffic, with the goal of achieving more efficient use of energy resources. With 26 completed projects, the TLS III Program has resulted in benefits that will pay for the cost of the program many times over. These benefits were estimated from the required before and after studies that were submitted by the cities. These studies document the major goals of the TLS III Program -- reductions in fuel consumption and unnecessary delay and stops. All projects were evaluated using the same unit costs. The TLS III Program resulted in 258 intersections in 19 cities being improved; the expenditure of $1.7 million of program funds and local matches; and annual reductions of 13.3 percent in fuel consumption (5.5 million gallons), 19.4 percent in delay (5.7 million hours), and 8.8 percent in stops (139 million stops). The total savings to the public in the form of reduced fuel, delay, and stops will be approximately $64 million in the next year alone. In regard to fuel savings, Texas motorists are realizing $3.28 in savings for every dollar spent, and if stops and delay are included, Texas motorists are realizing $38.13 in savings for every dollar spent. These savings will continue for the next few years without additional expenditures; therefore, the benefits to the public will be even greater.
