UDOT has been using the Deighton Total Infrastructure Management System (dTIMS) for our pavement management system software since the early 1990's. There is an online pavement section database component and an oracle server based deterioration model component. There is also an online dashboard with BI tools to access the system data.
The state highway system is broken into over 1,300 sections that are generally based on construction history. The 0.1 mile collected condition data is averaged for each section and a number of condition Index values are calculated. The Index values are on a 100 to 0 scale to normalize all of the various measures.
The deterioration model then forecast each of the Index measures, and evaluates all of the possible treatment strategies for every section. Each of the treatments in the model have a unit cost, and an associated benefit for each of the condition measures.
Multiple analysis scenarios are used to determine future condition forecasted at various funding levels, and to determine project recommendations using specific budget levels. Based on the available funding, the model selects projects based on the highest benefit to the overall system condition/ cost.
