Good Statistics are hard to come by for example look at the following:
The Trucking Home page uses total tonnage moved, even if that is a one block move or cross country:
“Trucks hauled 9 billion tons of freight in 2003, or 68.9 percent of tonnage carried by all modes of domestic freight transportation. Motor carriers collected $610 billion dollars, or 86.9 percent of total revenue earned by all transport modes.”
http://www.trucking.org/The federal Department of Transporation, Federal Railroad Administration Uses “Ton per mile”:
“In 2002.... the freight railroad industry produced over 1.5 trillion ton-miles that generated revenue of $36.9 billion. Seven major railroad systems accounted for 92 percent of the industry's total revenue even though the rail industry is composed of over 500 carriers..... The Surface Transportation Board (the Federal agency with jurisdiction over the economic regulation of railroads) classified seven railroads as meeting the Class I threshold with revenues greater than or equal to $272 million in 2002. In addition, according to the Association of American Railroads, there were 31 regional railroads and over 500 local (shortline or switching and terminal) railroads. The industry originated over 31 million carloads on a network consisting of nearly 142,000 miles of road. The industry employed over 177,000 employees.”

“Truck Transportation Estimated Number of Truck Miles Traveled by (in Million of Miles)
2002 86,927
2001 86,350
2000 86,252
1999 82,756
1998 78,834
Safety is clearly on the side of Railroads, so much that the Railroad are bragging about it:
“Railroads have only 10% of the incidents of spilling hazards materials compared to Trucks:”
http://www.uprr.com/she/cts/rvtruck.shtmlOne of the reason for the different statistics is that Railroads do a lot of bulk hauling, for example hauling coal. While most trucks do a lot of one loads shipping but such loads may have little eight (A truck delivering light weight paper products to your local food stores for example).
One thing that does come out of the statistics, trucking increased from 78,834 to 86,927 in four years (which is a good 10% increase in the total number of shipments).
I will try to get better stats.
