The pedestrian hybrid beacon (PHB) has shown great potential for improving pedestrian safety and driver yielding. However, questions remain regarding under what roadway conditions— such as crossing distance (i.e., number of lanes) and posted speed limit—should it be considered for use. In addition, there are questions about the device’s operations;

There is an increasing emphasis on shifting asset management practices toward cradle-to-cradle approaches (as opposed to cradle-to-grave approaches), where assets are not discarded at the end of their useful life but instead are consistently and systematically transformed into newer assets of equal or greater value. Such a continuous upgrade of the

State transportation agencies (STAs) continue to face the challenge of limited funding to build, improve, and operate their aging transportation infrastructure. At the same time, STAs are coming under increasing pressure from the public to be more transparent in how they use their resources, especially as they have to advocate for increased funding

The total project road length is about 1.35 miles in the City of St. Paul, Minnesota. The project was proposed to improve safety and reduce congestion by increasing roadway capacity, provide a smoother ride, improve drainage in the areas, and extend the service life of the roadway, bridges and drainage system. Figure 2 shows an overview of the proj
