En dépit de données canadiennes abondantes sur les associations entre aménagement urbain et comportements liés à la santé, nous savons peu de chose sur les associations entre aménagement urbain et problèmes de santé. Cet examen de la portée est destiné à offrir une synthèse des données tirées d’études quantitatives ayant examiné la relation entre l’...

Despite the accumulating Canadian evidence regarding the relations between urban form and health behaviours, less is known about the associations between urban form and health conditions. Our study aim was to undertake a scoping review to synthesize evidence from quantitative studies that have investigated the relationship between built environment and chronic...

State highway agencies (SHAs) continually face important financial decisions when planning a new or reconstructed highway. For example, what is the initial investment for the highway? How much is needed periodically to maintain the highway in good pavement condition? What materials should be used to build the pavement? The answers to these questions may require...

This document is the project report for the Connected Vehicle Infrastructure—Urban Bus Operational Safety Platform Project also known as the Enhanced Transit Safety Retrofit Package (E-TRP) project. The report describes the project’s background and purpose, summarizes its activities and results, includes results from an independent evaluation, and...

The British Columbia Active Transportation Design Guide is a detailed planning and engineering reference that provides practical design guidance and application information for active transportation infrastructure for jurisdictions of all sizes throughout the province. Building on international best practices, the Ministry of Transportation and...

Since Safe Routes to Schools (SR2S) methods first gained prominence in the 1990s, researchers and practitioners have been working to determine best practices that can yield improvements in two areas: improved health and increased ATS participation. Many of these projects and programs have focused on the provision of physical infrastructure that can improve...

This report examines how freight transport/goods movement has been addressed in U.S. city climate action planning. Transportation generally is a major contributor of greenhouse gas (GHG) emissions, and freight transport represents a growing component of transportation’s share. Almost all climate action plans (CAPs) address transportation generally, but we...

Detailed Intersection Control Information (ICI), including timing, phasing, geometric, and demand attributes, is an increasingly important resource for researchers, consultants, and private sector companies for many applications, including development of traffic models and technologies such as vehicle information or automation systems. While this information...

Increasing cycling shares is a part of the urban and transport planning mandate for the Norwegian urban regions. The pathways to increase bicycling shares can be plotted at both macro and micro levels. At micro levels, road designs and measures to both improve the conditions for cyclists and make cycling paths safer can lead to potential increase in bicycling....

This reports benchmarks road safety performance for 72 urban areas, mostly in Europe, and illustrates governance solutions to improve urban road safety with case studies conducted in Lisbon (Portugal) and Riga (Latvia). The report proposes new road safety indicators to assess the level of risk for each mode of transport. It finds that a modal shift away from...

Transportation infrastructure intersects challenging terrain that can negatively impact integrity. Minnesota’s climate, geomorphology, and steep terrain along rivers increase the incidence of slope failures such as rockfalls and landslides. WSB was contracted by MnDOT to determine the risk of slope failure along state highways in districts 6, 7, and the...

The purpose of this project was to estimate regionalized safety performance functions (SPFs) for urban and suburban collector roads and at-grade intersections using roadway inventory and crash data from state-owned roadways in Pennsylvania. Five years of crash data (2013-2017) were appended to traffic volume and roadway and roadside features in order to...
