... Defining roles will be an essential part of the research plan because most research and data collection will require active participation of state highway agencies. Some of the research and data needs described above would also require local highway agency and private industry participation.

... Comparing the estimates in the past USDOT and TRB truck size and weight limit studies shows that differences from study to study in the magnitude of impact estimates are greater for certain impact categories than for others. A primary example is estimates of the cost of protecting bridges if gross weight limits are increased.

... The potential effects of changes in limits on road safety, traffic, and competition between the trucking and railroad industries are impact categories that have received heightened priority because of this consideration. Potential Value of Research Results for General Highway Management Applications Much of the research and data collection activities that USDOT recommended in its 2016 truck size and weight study's final report (USDOT 2016, 20–24)

... Assumed Objectives of the Regulatory Changes Under Consideration To set research priorities, it will be necessary to make assumptions about the range of truck size and weight policy options that will require analysis. For example, it was noted above that in past studies, the estimated effect of limit changes on pavement costs has been small because changes in axle weight limits have not been regarded as an important policy option.
