Abstract:The Transportation Service Center (TSC) concept originated as a result of the department?s evaluation of its key business processes and its commitment to improve the quality of the goods and services it provides. TSCs are local Michigan Department of Transportation (MDOT) offices that are multi functional, multi modal and the primary focus for MDOT?s external customer contact. The final goal is to locate TSCs so that no employee will drive more than one hour to get from their office to a work site and every customer will be within sixty minutes of a TSC. This paper and presentation outlines MDOT?s Travel Demand Analysis Section (TDA) utilization of the Statewide Travel Demand Model and TransCAD?s GIS and travel demand modeling capabilities to provide technical support to this location determination for the TSCs. The combination of providing data and profiles along with the ability to illustrate this data with maps and graphs, was very useful in communicating the findings to MDOT management and the MDOT work force. Included in this presentation and paper are what technical procedures worked and what didn?t, what was effective in communicating results to others, and suggestions on how the process can be improved. Analyses performed include geocoding and mapping the locations of potential TSCs, Regional Centers and employee home and business locations using TransCAD?s address matching capabilities; using TransCAD?s partitioning procedure to calculate the population within 10 minute travel time increments and the percent of the total state population served within these time bands; and calculation of the average travel time to work for existing employees.
