A MODEL FOR EVALUATING AUTOMATION IN ROAD MAINTENANCE

Automated road and highway maintenance has extremely high potential because of its many benefits, including direct and indirect cost savings (economic factors); improvements in safety, quality, working environment, and productivity (qualitative factors); and reduction in emissions and fuel/oil consumption due to the expedited maintenance operations (environmental & energy factors). A comprehensive Automated Road Maintenance Evaluation (ARME) model was developed through which the benefits of all these factors can be evaluated by a system's approach. Using the analysis tools of the model, the automation feasibility of the major maintenance activities was evaluated using the ARME model's needs assessment phase tools, and the feasibility of an Automated Crack Sealer (ACS) system was evaluated using the ARME model's technology evaluation phase tools. Of the 25 maintenance activities evaluated, only 13 were found out to be feasible for automation. Most of these activities (7 out of the 13) are pavement related, four are roadside maintenance activities, and two are traffic related. In evaluating the feasibility of the automated crack sealer, estimated maintenance cost savings, user-cost savings, reduction in emissions/energy consumption, and the improvements in the qualitative factors were determined. Several scenarios, from both the Texas Department of Transportation and private contractors' perspectives, were analyzed; and in every scenario the system proved to be very feasible for all the analysis factors (economic, qualitative, environmental & energy).
