Throughput during peak-period traffic at signalized intersections with high left-turn demand commonly creates a bottleneck. Two intersection configurations designed to increase the capacity at locations without adding lanes are the dynamic reversible left-turn (DRLT) lane at diamond interchanges and contraflow left-turn (CLT) lane at signalized int

The movement of superheavy loads (SHLs) has become more common over the years, since it is a vital necessity for many important industries, such as chemical, oil, electrical, and defense. SHL hauling units are much larger in size and weight compared to standard trucks. SHL vehicles' gross vehicle weights may be in excess of a few million pounds, so

The movement of superheavy loads (SHLs) on the Nation's highways is an increasingly common, vital economic necessity for many important industries, such as chemical, oil, electrical, and defense. SHL hauling units are much larger in size and weight than standard trucks. SHL gross vehicle weights may be in excess of a few million pounds, so they oft

This project aims to develop PedPal, a mobile app that enables pedestrians with disabilities to more safely and more efficiently cross signalized intersections. The proposed technology concept is a smart phone app that interacts directly with a real-time, adaptive traffic signal control system at the intersection via 3G/4G wireless ration technolog

PDF
The purpose of this brief is to explore how children (ages 5–17) travel to school in the United States. The National Household Travel Survey (NHTS) obtains data on children’s usual travel to school in support of policies and plans to encourage more children to walk and bike to school as well as to help local planners make those trips safer.
This Public-Private Partnership Procurement Guide (Guidebook) has been developed in coordination with the U.S. Department of Transportation (U.S. DOT) Build America Bureau, the Federal Transit Administration (FTA) and the Federal Highway Administration (FHWA) to provide advanced guidance on procedures, issues, and considerations involved in public-

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

In 2010, FHWA developed a new systematic, data-driven, risk-based oversight process for monitoring State compliance with the National Bridge Inspection Standards (NBIS). Based on the success of that process, FHWA has now developed a similar process for the recently implemented National Tunnel Inspection Standards (NTIS) required by 23 U.S.C. 144(h)

Congestion pricing works by shifting some rush hour highway travel to other transportation modes or off-peak periods and by encouraging solo drivers to carpool or forgo making a trip altogether. By removing a fraction (even as small as 5 percent) of the vehicles from a congested roadway, pricing enables the traffic to flow much more efficiently, al
