Route Optimization

ECO-routing today is very simplified Very little research available on

route optimization and navigation for trucks

Could be improved by already available road data

Truck navigation requires more processing and storage capacity than most current navigation systems.

No combination of route optimization and advanced driver assistance systems (ADAS) found

Business Models

No companies have a clearly stated strategy to deliver energy-efficient products to the truck market

The major inhibiting factors are the relatively small number of trucks compared to cars

The cost for wireless communication is still a major barrier for extensive use of real time data
