Simulation Modeling of Electronic Screening at Weigh Stations

Electronic screening of trucks before reaching points of regulatory compliance checks (typically, weigh stations) would allow for more efficient use of government resources while reducing travel time for motor carriers. A study was done of the effects of electronic screening on reducing travel time and enhancing productivity of the weigh station using a new simulation model. The model illustrates the impact of electronic screening on motor carrier travel time savings and weigh station productivity assuming various levels of transponder-equipped vehicles. The results indicate that as participation grows, enforcement agencies and participating (transponder-equipped) and nonparticipating trucks all share in the benefits afforded by a more efficient system.
