Measuring Improvements in the Movement of Highway and Intermodal Freight
This study is considerably above the average. A number of the measures presented are not only relevant to highway freight but specific to trucks. Annual hours of truck delay is a good example, but it also raises a question about data. The idea of designating a freight system is a good one; the test would be whether roads that carry a disproportionate share of freight or are key links in the freight network were actually selected. If it is simply the high-level roads, then measures based on it are still general highway measures. Percentage of obstacles to freight movement removed would be good in principle. There is an obvious problem of definition and counting; what is an obstacle and how do you establish the base number of obstacles? An appealing feature of this measure is that it actually ties back to actions of the State.
