Automated vehicle (AV) technology has the potential to completely change how we travel, how we ship goods, and on a larger scale, how we think about mobility. While fully automated vehicles are not yet commercially available, the technology is developing rapidly and some robotic driving functions are already on public roads today. Nevertheless, the challenges...

Le rapport présente l’état actuel des connaissances sur les risques climatiques pour le secteur canadien des transports et identifie les pratiques d’adaptation existantes ou potentielles. Le rapport comprend six chapitres sur les régions et un chapitre sur le secteur urbain qui reflètent les différentes répercussions des changements climatiques et...

This report presents the current state of knowledge about climate risks to the Canadian transportation sector, and identifies existing or potential adaptation practices. The report includes six regional chapters and one urban chapter which reflect the different climate change impacts, vulnerabilities and opportunities across Canada. Adaptation approaches are...

This paper investigates the trends of longitudinal and transverse cracking in jointed concrete pavements based on Long-Term Pavement Performance (LTPP) Program Strategic Study of Structural Factors for Rigid Pavements (SPS-2) data. The impacts of slab properties, base type, traffic volume, and environmental factors on the occurrence and extent of longitudinal...

Center line rumble strips (CLRSs) and shoulder rumble strips (SRSs) are proven countermeasures for reducing roadway departure crashes, including head-on and run-off-road crashes. The objectives of this project were twofold. The first objective was to develop a rumble strip decision support guide to inform agencies on CLRS and SRS installation. The second...

This report describes the efforts undertaken to review the status of falling weight deflectometer (FWD) equipment, data collection, analysis, and interpretation, including dynamic backcalculation, as they relate to the models and procedures incorporated in the Mechanistic-Empirical Pavement Design Guide. The full report is available from the FHWA web site at...

Snow and ice control operations are a vital function often conducted by state and local transportation agencies. Many states are choosing to contract snow and ice response services, instead of or in addition to the use of in-­house forces, to maintain lean departments and avoid the equipment responsibilities. This has been a common practice for years, at...

Automated vehicles are gradually entering our roadway system. Before our roads will be solely used by fully automated vehicles, a long transition period is to be expected in which fully automated vehicles, partly automated vehicles and manually-driven vehicles have to share our roads. The current report looked into the position of pedestrians and cyclists in...

Increasing travel demands and an aging highway infrastructure drive the need for extensive construction, maintenance, and utility work zones. The introduction of work zone environments creates risks for both drivers and construction workers due to changes from the normal driving environment. Temporary speed limit reductions are a common countermeasure aimed at...

The bump at the end of the bridge has long been studied for highways and railways, yet experts from across the transportation industry continue to identify it as one of the most prevalent substructure factors affecting bridge performance. Often, rideability is a subjective measurement used by transportation departments to define the presence of a bump. User...

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 505: Current Practices and Guidelines for the Reuse of Bridge Foundations provides guidance on reusing bridge foundations, a sustainable option for many bridge replacement and rehabilitation efforts that can result in time and cost savings as well as reduced mobility impacts and...

This paper presents a risk-based approach for classifying the road surface conditions of a highway network under winter weather events. A relative risk index (RRI) is developed to capture the effect of adverse weather conditions on the collision risk of a highway in reference to the normal driving conditions. Based on this index, multiple risk factors related...
