Interstate highway travel could be getting a little smoother in coming years.
That’s if a Texas Transportation Institute plan to move some 18-wheeler freight above the roadway proves feasible.
Dr. Stephen Roop, Senior Reseach Scientist for TTI on the A&M campus said the system, called Freight Shuttle, is track-based.
He said it’s it’s not like rail freight in that only one container is transported at a time.
The system could address two areas of congestion: border crossings, where removing the driver from the process would allow 100% of cargo to be X-Rayed, and corridors, such as along interstates.
Dr. Roop said a full-scale test track should be available for demonstration by the end of the year.
The all-electric system could operate elevated above interstates in the existing right of way.
Similar to rail systems, the wheels would travel steel-on-steel to reduce rolling resistance.
Dr. Roop said that could help reduce the cost to about $0.10 per mile—about one-seventh the cost of transportation on rubber tires over traditional roadways.
