Basically, in the last 20 years the average length of haul for dry van truckload has dropped from 800 miles to around 500 now. This is a graphic that I pulled out of an ATRI report, I think the data was generated by the American Trucking Association. The first trend that we see a lot in the press is the decreasing length of haul for the long-haul trucking or the truckload sector. So, this systems perspective is luckily becoming more prevalent in our thinking. I also work a lot with a 21st-Century truck partnership, and we have a freight efficiency tech team as well. I would also like to point out working at NREL we have taken that mobility perspective recently and made it official in the name of our group.

So, for example, VTO does have a program called exactly that at the Vehicle Technologies Office at the DOE. But, kind of more recently, we have started to take the broader view of energy efficient mobility systems. The classical R&D in terms of truck freight efficiency has looked at powertrain and vehicle technologies and payload capacity, rather than looking at this whole systems view. The condition of the road and also congestion. Instead of network efficiency, I wanted that to say network accessibility so that we are not talking about the Internet, we are talking about our connection or our ability to access the road network. I'm afraid I forgot to change something on here. Then we also have the road system, the network efficiency.
