Contextual Guidance at Intersections for Protected Bicycle Lanes

Christopher Monsere
Nathan McNeil
Protected, or separated, bike lanes have become increasingly common around the United States. Studies have consistently found that people prefer bike facilities that are separated from traffic, such as off-street paths and protected bike lanes, with physical separation such as a post or curb providing increased comfort. The preference for these separated facilities appears to be greater amongst cyclists who ride primarily for recreation (as opposed to for transportation) and among those who c... Read More

Bridge Seismic Retrofit Feasibility Case Study Utilizing Ductile Fuses

Peter Dusicka
In an effort to increase the seismic resiliency of our transportation network, a performance centric retrofit measure has been developed as part of State funded research and evaluated through to large scale laboratory setting. With an eye toward implementation, this technology transfer proposal aims to conduct a feasibility study on incorporating this retrofit measure with a recently developed ductile fuse technology and applying the retrofit to a real bridge case study. The intent is to deve... Read More
