Abstract:This project for the Texas Department of Transportation (TxDOT) developed a simple but sound
methodology for estimating the cost of delaying most types of highway projects. Researchers considered the
cost of delays during the pre-construction phases of project development: planning and scoping, preliminary
engineering, final design, and letting. Researchers developed a simplified model that incorporates 16 usercontrolled
variables and produces estimates of the effect of project delay on personal and commercial travel
and the cost to the general economy. While the methodology is simple, there is no rule of thumb because
project delay costs depend on several variables, primarily location, traffic, construction costs, and travel
speeds.
