The Oregon Department of Transportation (ODOT) requires an ODOT employee to collect weigh slips from delivery vehicles on road construction. These delivery vehicles may be hauling asphalt mix or aggregates. The person, usually a temporary employee, is given the job title "ticket taker". The job is one of the most dangerous jobs on the construction project. The purpose of this project was to eliminate the dangerous ticket taker job with an automatic system. The ticket taker automation system is a very high frequency radio operating at 2.45 GHz. An interrogator unit, attached to a laptop computer, transmits data to a small transponder that can store 256 bytes of data. Transponders are attached to the trucks hauling asphalt mix. At the hot mix plant, a signal is sent to the transponder and stored. At the jobsite, the interrogator reads the signal and stores the data in the attached computer. Both a scale unit and a job site unit are required for this system. This project was a preliminary test of the system in a road construction environment. The results of the study indicate that the limited range of the system (20 m) would require an operator to move the system as the job progressed forward. Ticket taking would not be eliminated, but made safer by automation. Based on the results of the study, the system is not suitable for implementation at this time. 25 p.
