This document reviews notable practices and considerations for accommodating pedestrians with vision disabilities on shared streets. It focuses on streets where pedestrians, bicyclists, and motor vehicles are intended to mix in the same space. The guide includes a description of shared streets, an overview of vision disabilities and the strategies people with...

Gender is one of the key socio-demographic variables that can influence travel behaviour, but it is often the least understood. Understanding travel behaviour by gender will help better design transport policies that are efficient and equitable. Due to the gendered division of work in households, women often have multiple tasks and activities. As a result,...

The accumulation of chloride in surface waters and groundwater from road deicing and other sources is a growing problem in northern cities of the U.S., including the Minneapolis-St. Paul metro area. To inform mitigation efforts, the transport of chloride in surface waters of a metro-area watershed (Lake McCarrons) was studied in this project to characterize...

Precast/prestressed double tee bridge girders are widely used for accelerated bridge construction on local roads in South Dakota. A common issue among existing double tee bridges in South Dakota is the rapid deterioration of longitudinal joints (shear keyways) between adjacent girders. Deteriorated joints allow moisture and deicing chemicals to reach the deck...

This study evaluated the application of edge line rumble stripes (ELRSs) on rural, two-lane horizontal curves. This strategy was intended to reduce the frequency of run-off-road (ROR) crashes and nighttime crashes by alerting drivers that they are about to leave the traveled lane and by enhancing visibility of the edge line during nighttime and wet-weather...

This report documents the results of IDEA project 179, Development of a Portable Stress Measurement Instrument. An ultrasonic stress measurement (USM) instrument has been developed that provides bridge engineers with quantitative measurements of the in-situ stresses in bridge members. The instrument is very unique because there are no other practical total...

To address the need for a rational but fast method to determine costs and a proposed permit fee, the research team developed the Stage 1 Expedient Analysis Method. The method was used to evaluate potential oversize/overweight (OS/OW) freight corridors that will serve Texas coastal port regions and border POEs during Stage 1 of this project. Using the method...

Bridge decks are commonly rehabilitated using overlays depending on the cause of deck deterioration, available budget, and desired service life of the rehabilitated structure. One emerging solution for bridge deck rehabilitation is thin, bonded ultra-high performance concrete (UHPC) overlays. As an overlay material, UHPC can provide both structural...

A comprehensive laboratory testing program was conducted in this research project to examine the blending between reclaimed asphalt pavement (RAP)/recycled asphalt shingles (RAS) and virgin asphalt binders and to evaluate the factors that may affect fatigue and low-temperature cracking as well as moisture-induced damage in asphalt mixtures prepared using these...

This Transportation Research Synthesis (TRS) summarizes non-chloride based deicers available on the market at this time, including acetate, formate, glycol, and succinate based deicing products. This report explores their feasibility for use as alternatives to chloride based deicers, and identifies next steps to determine if a non-chloride based deicer is a...

A number of Connected and/or Automated Vehicle (CAV) applications have recently been designed to improve the performance of our transportation system. Safety, mobility and environmental sustainability are three cornerstone performance metrics when evaluating the benefits of CAV applications. These metrics can be quantified by various measures of effectiveness (...

This guideline document is prepared to guide pavement maintenance personnel in the selection, installation, and evaluation of materials for hot-poured crack sealant treatments for flexible pavements. The information provided in this guideline is based on the field performance of 17 conventional sealants installed at five different sites in North America as part...
