Building wider highways only creates a greater demand for driving and thus creates a greater demand for foreign oil. This is the old way of thinking.
We need to look at getting back to rail transportation for both freight and passenger service.
I disagree that building highways creates a greater demand for driving - wider highways are built to accommodate demand that is already there.
I agree that freight rail can be used more than it currently is, although it's used a lot more than people want to give it credit for (anyone who went to ISU knows freight trains pass through every 20 minutes or so). That being said -
- You can't attach everything with rail - it's not economically feasible to do so. You need a viable trucking industry to fill in the gaps.
- According to an economics professor in my MBA program that also used to be a forecaster for the rail industry, this nation already has significantly more rail than it needs, so much so that it blows past economies of scale and is actually a drain on the system because track has to be maintained that just isn't used.
