This process was required due to the complexity of the striping operation pattern and telematics device sensors. This study mainly used operation data collected from a single striping season between April 1, 2012, and November 30, 2012. Centerline and edgeline trucks have different patterns of operation. The centerline truck sprayed either single or multiple stripes using solid or skipped lines, while the edgeline truck sprayed a single stripe in a less complicated process. The production algorithm was determined to measure only driving distance while striping. The average productivity (production rate) of a centerline truck was 18.3 miles/day in Crawfordsville and 17.1 miles/day in Greenfield. Crawfordsville and Greenfield districts operated on 66 and 80 days out of 244 calendar days, respectively, during the striping season. The centerline production rate ratio between total driving distance and striping distance is only approximately 15 percent. Productivity rates for the edgeline trucks are 29.5 miles/ day in Crawfordsville and 30.6 miles/day in Greenfield. The edgeline trucks were operated only 46 days in Crawfordsville and 44 days in Greenfield. The edgeline production rate ratio between total driving distance and striping distance is only approximately 25 percent. The productivity analysis revealed that there was a significant opportunity to improve low productivity in terms of actual striping distance as compared to total driving distance. Utilization is defined as the ratio between a number of operation days and calendar days, or weekdays, in a month. An operation day is counted whenever a truck stripes, regardless of the production rate. The Greenfield district operated with the highest centerline truck utilization rate at approximately 46 percent, and lowest edgeline truck rate at 25 percent over all weekdays. The Crawfordsville district operated with a centerline rate at 38 percent and edgeline rate at 26 percent over all weekdays. Idling analysis provides a measurement of vehicle operation inefficiency in terms of excessive unnecessary fuel consumption and idling between striping operations. Idling is defined as cumulative time while the engine is running but a truck is not moving. A total of 268 idling hours were recorded by the telematics, and an estimated 268 gallons of diesel fuel, Introduction
