This project studied the performance of geotextile-reinforced test sections when compared to an unreinforced case to assess benefit in terms of an extension of the life of the pavement. A single test track was constructed in an indoor test facility and contained two test sections with a reinforcement geotextile (woven and non-woven) while the third section was...

Municipalities across Minnesota have turned to Complete Streets in an attempt to develop more usable roads for their residents. This report investigates how Complete Streets are reshaping one Minnesota community. In 2013, Richfield, a suburb of Minneapolis, enacted a particularly innovative Complete Streets policy. Known locally as "Richfield Sweet Streets...

A study was undertaken to investigate the source of the Ohio DOT culvert outlet protection design methodology and to compare this method with other State DOTs and FHWA methodologies.  The original source of the Ohio DOT methodology was long thought to be a study conducted by The University of Cincinnati (Laushey, 1966).  However, a meaningful...

Application of exterior coatings and membrane waterproofing on precast reinforced concrete box culverts, three-sided flat-topped culverts, and precast reinforced concrete arch and round sections is required by Ohio Department of Transportation (ODOT). Sealing and waterproofing limit the intrusion of ground water through the top of the joint and it protects the...

This pilot project is one among many efforts by the Iowa Department of Transportation (DOT) and the Iowa Highway Research Board (IHRB) to develop and enhance a risk-based transportation asset management plan (TAMP). This project specifically focused on flooding and developed a suite of methodologies and proxy indicators to assess the risk of transportation...

Estimating latent, or suppressed, demand for walking and cycling is an emerging science in New Zealand, with limited research into the application and effectiveness of the different methods employed around the country over the past decade. This first stage of this research employed a literature review, and a survey and interviews of practitioners, to understand...

This report presents an analysis of the potential macroeconomic impacts resulting from the adoption of higher level automated driving systems (ADS) of the long-haul trucking industry in the United States. The analysis uses USAGE-Hwy, a computable general equilibrium (CGE) model of the U.S. economy that includes detail on transportation related industries...

Digital terrain models (DTMs) are three-dimensional (3D) models of the ground surface showing natural features such as ridges and breaklines. The TRB National Cooperative Highway Research Program's NCHRP Synthesis 560: Practices for Construction-Ready Digital Terrain Models documents processes and strategies used by state departments of transportation (DOTs...

The objective of this study was to perform rigorous safety effectiveness evaluations of adaptive signal control technologies (ASCTs) used on urban corridors. To accomplish the goal of this study, the research team compiled safety data from Florida, Texas, and Virginia. Results from Florida and Texas did not offer statistical evidence of a change in safety...

In 2015, the Road Ecology Center at UC Davis developed a web-based method to collect all incident data that appear on the CHP real-time incident-reporting website (https://cad.chp.ca.gov/). These data are assembled into a database called CHIPS, the California Highway Incident Processing System. Previous analyses suggest that these data are more spatially...

The overall objective of this project was to create a set of guidelines that can be used to inform the development of risky driving countermeasures that are evidence-based, guided by theory, and lead to sustained behavioral change. Several tasks were completed to achieve this objective including: developing a behavior change inventory; identifying candidate...

The remaining service interval (RSI) is a pavement lifecycle–management framework intended to help highway agencies make sound long-term investment decisions. The RSI approach uses one or multiple performance measures as the basis for setting and achieving highway performance goals. The approach can also be used for pavement lifecycle planning (LCP). This...
