The Ohio Department of Transportation created the Pedestrian Safety Improvement Program to rapidly implement low and medium-cost countermeasures along arterials and collectors. The program incorporates STEP countermeasures at midblock locations and intersections.
The Los Angeles Department of Transportation (LADOT) installed a road diet on Rowena Avenue in the Los Angeles neighborhood of Silver Lake in 2013. The four-to-three lane conversion along the high-volume corridor resulted in fewer overall crashes and increased bicycle usage. Since the Rowena Avenue project, LADOT has implemented dozens of road reco

The Rhode Island Department of Transportation (RIDOT) inventoried all uncontrolled pedestrian crossing locations on state-maintained roadways to guide a new systemic analysis for safety improvements. The new inventory is integrated into the state’s Transportation Improvement Program (TIP) project scoping and maintenance activities.
The Broward Metropolitan Planning Organization (MPO) is the federally-designated transportation agency for Broward County, Florida. The county had been consistently ranked as one of the most dangerous places to walk and bike in the country, with an average of 5-6 walking or bicycling crashes per day. In response, the MPO led the development of succ

The dispersed nature of pedestrian crashes often means that pedestrian safety countermeasures are installed in response to pedestrian crashes, rather than regularly installed in locations with factors that contribute to high pedestrian crash risk. The Virginia Department of Transportation (VDOT) combined hot spot and systemic analysis to proactivel

This case study covers the overall building information modeling (BIM) for infrastructure approach used in the Kew Gardens Interchange (KGI) project, as well as considerations for model development and positive impacts to the project as a result of BIM use.
Alkali—silica reaction (ASR) is a chemical distress mechanism that adversely affects the service life of concrete pavements. Key aspects of the reaction, such as the roles of calcium and aluminum on the structure of the gel and their correlation with swelling properties, have not yet been fully understood owing to the complex reaction mechanism. Th
