On a monthly basis, each State is required to report to the Federal Highway Administration (FHWA), the amount of gallons taxed by that state. This data is analyzed and compiled by FHWA staff. The data on the amount of on-highway fuel use for each State is then used to attribute federal revenue to each State. Yearly, the FHWA, Office of Policy, prov

The greatest barrier to using 3D digital design data in highway construction is ineffectively managed uncertainty regarding whether the constraints assumed in design reflect actual field conditions. Verifying the original ground close to construction is an effective, digital preconstruction quality control method to avoid basic construction issues.
...
There are numerous benefits afforded to using 3D digital design data in highway construction. These include: the ability to identify and resolve constructability challenges prior to mobilization, more accurate estimation and better control of pavement material quantities through Automated Machine Guidance (AMG), faster execution of construction wit

Center line rumble strips (CLRSs) and shoulder rumble strips (SRSs) are proven countermeasures for reducing roadway departure crashes, including head-on and run-off-road crashes. The objectives of this project were twofold. The first objective was to develop a rumble strip decision support guide to inform agencies on CLRS and SRS installation. The

Based on current practices, traffic simulation models are calibrated and validated using macroscopic measures such as 15-minute averages of traffic counts or average point-to-point travel times. For an emerging number of applications, including connected vehicles, the realism of simulated driver dynamics at the second-by-second or sub-second trajec
