Generally, reduced left-turn conflict intersections are geometric designs that lessen the number or severity of potential vehicle-to-vehicle conflicts associated with left-turn movements. Two of these highly effective intersection designs are included in this FHWA Proven Safety Countermeasure—the restricted crossing U-turn (RCUT) and the median U-t

This example involves the replacement of stringers during re-decking on an existing truss/floorbeam/stringer bridge. The existing stringers are non-composite rolled W24x76 beams, that were designed for HS-20 live loads. The design criteria is to provide new stringers to obtain a HS-25 live load rating factor equal to or greater than 1.0, while mini

Shared mobility services provide users with short-term access to transportation on an as-needed basis rather than through ownership. While ride-sourcing services are recent entrants to the industry, they have come to dominate what is thought of as shared mobility in the United States, often drowning out other shared alternatives. In Europe, the con

PedPal is a prototype mobile (smartphone) app designed to assist pedestrians with disabilities when crossing the street at signalized intersections. PedPal interacts directly with the traffic signal system controlling the intersection to communicate both crossing intent (eliminating the need to seek out and push a pedestrian call button) and person
