The new Complete Streets Design and Construction Standards, which govern roadway design in the City of Edmonton replace the 2013 Complete Streets Guidelines. The Complete Streets approach moves away from traditional design by designing streets that reflect the surrounding area’s context, land use and users. A complete street integrates all road users...

Data is essential for understanding the demands placed on road assets and transport networks. There is an opportunity through advances in real-time technologies to improve the delivery of network management and asset management activities. This requires an understanding of both the real-time technologies that are available, and the real-time information needs...

This report examines how increasing automation of cars and trucks could affect road safety, and which security vulnerabilities will need to be addressed with the rise of self-driving vehicles. It applies the principles of the Safe System approach and relevance of Vision Zero for road safety to the wider discussion on vehicle automation. It also takes into...

This research report presents an improved process for evaluating the benefits and economic tradeoffs associated with a variety of highway preservation projects. It includes a summary of results from a comprehensive phone survey concerning the use and application of the software developed by the Federal Highway Administration (FHWA), known as the Highway...

Maintaining effective pavement markings year-round is a challenge in Iowa, where winter maintenance causes so much damage due to the harsh winter exposure from snow plow blades, sand, and salt brine. Given these conditions, and a limited painting season, it is critical that agencies select the proper pavement marking materials for the roadways in their network...

In this white paper, the available evidence on the travel and environmental effects of automated vehicles is critically reviewed to understand the potential magnitude and likelihood of estimated effects. We outline the mechanisms by which automated vehicles may change travel demand and review the available evidence on their significance and size. These...

Research shows that pothole prevention requires repairing pavement cracks as they develop. Repairing potholes effectively is more difficult in winter than in summer. Durable winter repairs require expensive patching materials and expensive, on-site heating technologies. Taconite mixes and mixtures modified with graphite nanoplatelets show promise for long-...

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 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...
