Evaluating Alternative Operations Strategies to Improve Travel Time ...

SHRP 2 L11: Final Appendices
With potential cost saving benefits ranging from $11.77 to $16.20 per air-freight shipment, Electronic Supply Chain Manifest could
save the freight industry more than $2 billion per year (2).
In Maryland, electronic screening and credentialing systems provide a B/C ratio ranging 3.28 to 4.68 (3).
An advanced routing and decision-making software communications program for commercial vehicles helped dispatchers organize
and route time-sensitive delivery orders. The system increased the number of deliveries per driver-hour by 24 percent (5).
In Washington State, it is estimated that commercial motor carriers save $1.25 for every minute that they are not idling in weigh
station queues. Automated reporting and record keeping technology reduces costly paperwork for government and motor carriers
(30).
Use of e-seals at for a for a dedicated ITS Truck lane at the border Washington/British Columbia order indicates a B to C ratio
ranging from 29:1 to 42:1. These lanes allow freight, equipped with transponders, to pass through the border with lower rate of
inspection (31).
A study of port controls and access appointment systems indicated technology could increase vehicle productivity by 10 to 24%
and access capacity by 30%.
• Energy/Environment: In Chicago, a feasibility study indicated that automated truck-way technologies (automatic truck steering,
speed, and platoon spacing control) would save travel time and reduce fuel consumption (1).
In Colorado, an automated commercial vehicle pre-screening system installed at 3 ports of entry check stations saved 48,200
gallons of fuel per month (2).
• Customer Satisfaction: Carriers surveyed indicated they were very satisfied with the ability of electronic supply chain manifest
systems to duplicate paper-based systems (1).
