In the mid-continent transportation corridor, a study of electronic screening technologies found that benefit-to-cost ratios for motor carriers and state agencies range from 6.0:1 to 11.9:1.
- Electronic Credentialing
- Electronic Screening
- Electronic Border Screening
To evaluate the benefit-to-cost (B/C) ratios for each of these technologies three different growth scenarios (conservative, expected, and aggressive) were analyzed to account for future market penetration . These three scenarios were then evaluated against estimates of high and low deployment cost to account for large-scale as well as small-scale motor carriers.
Electronic Screening data was derived from 19 static scales. The following were evaluated: hours of operation, the number of trucks weighed, and the number of safety inspections performed (level I,II, or III).
Electronic Screening benefits for carriers included savings on fuel and time as carriers were able to bypass static-scales and reduce mainline delays. Benefits to states included reduced weigh station pavement repair costs and other labor savings. The deployment cost to motor carriers included the purchase of electronic transponders at a price of approximately $50 per vehicle. The cost to state agencies was much higher and included the purchase of automatic vehicle identification readers (AVI), weigh-in-motion (WIM) scales, and other equipment and maintenance at a cost of approximately 150,000 to 780,000 dollars per station.
The benefits of Electronic Screening exceeded the costs for both motor carriers and state agencies . The B/C levels were positive even at low truck volumes and low enforcement levels. The relative low cost of deployment contributed to the increased levels of benefits.
The B/C ratios for motor carriers and state agencies were combined to give the following overall results for Electronic Screening.
