The Development of Crash Modification Factors (CMFs) program conducted safety evaluation of profiled thermoplastic pavement markings for the Evaluation of Low-Cost Safety Improvements Pooled Fund Study. This study evaluated application of profiled thermoplastic pavement markings. This strategy involves upgrading existing markings from flat-line thermoplastic or...

This report presents the implementation of new design method developed using mechanistic-empirical design approach by University of California Pavement Research Center (UCPRC) through building two test sections at California State University Long Beach (CSULB). The study includes a literature review, pavement design procedure, mix design, construction procedure...

This report provides best practice recommendations for the development of Road Safety Infrastructure Programs (RSIPs) that align with the safe system approach. For many years, investment in road safety infrastructure in Australia and New Zealand has taken a bottom-up approach of targeting safety improvements at locations with an established safety...

This study aims to document objectively the relationship between vehicle speed and crash risks. It assesses to what extent recent changes in speed limits or the wide-scale introduction of automated speed enforcement have moderated actual average speeds, and whether this has delivered the safety impacts that theoretical models of the relationship between...

Flexible pavement rutting due to permanent deformation accumulation in asphalt layers is one of the most common modes of road failures. In addition to creating high maintenance costs, rutting is a major concern for traffic safety, as the rut development increases the risk of hydroplaning and introduce difficulties in vehicle steering. In this context, accurate...

Minnesota DOT's current pavement thickness design procedures do not characterize the effects of subgrade soil frost susceptibility. Previous research indicates frost action is the most severe environmental factor on pavement performance. The most accepted mitigation practice is to replace the frost-susceptible material with non-frost-susceptible material to...

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...
