In Progress

Projects are considered to be in progress once sufficient funding has been secured to cover all costs associated with the conduct of the project.

The projects currently in progress are listed below and information about each project is available by clicking on its title. 

Once a project is completed, it is transitioned into a publication, and made available through TAC's Bookstore

Newly constructed or rehabilitated bridges are frequently surfaced with hot mix asphalt (HMA); however, achieving high quality asphalt mats on bridges presents many challenges.  To prevent damage to the bridge, vibratory compaction is usually not permitted...

Chapter 4, Cross Section Elements of TAC’s Geometric Design Guide for Canadian Roads (GDG) addresses design procedures and domains related to road cross sections (e.g. lane widths, special purpose lanes, shoulders, medians, outer separations and...

Most fatal and serious injury motor vehicle collisions in urban areas occur on arterial roadways. Because the risk of death and serious injury in collisions is minimized at lower speeds, a significant opportunity for improved safety lies in the design and...

The Guide to Bridge Hydraulics, Second Edition (2001) addresses hydraulic and hydrologic design issues related to bridge infrastructure, and is referenced in the Canadian Highway Bridge Design Code and other publications. In view of the urgent need to adapt to...

This project will develop a major national guide to complement the Geometric Design Guide for Canadian Roads (GDG) and the Manual of Uniform Traffic Control Devices for Canada (MUTCDC). The guide will focus on engineering aspects while...

Shared micromobility services involve shared-use fleets of small, fully or partially human-powered vehicles such as bikes, e-bikes and e-scooters. Shared micromobility services are either operating or being planned in cities and regions across Canada, reflecting...

Practitioners wishing to provide safe and effective traffic signal timing for all road users increasingly face dilemmas at traffic signal-controlled intersections when high-capacity active transportation facilities are deployed. As an example, bidirectional...

Recycled asphalt pavement (RAP) can be used in roadway bituminous mixtures as a cost-effective portioned replacement of virgin aggregate skeleton and asphalt binder. To be successful, mixtures containing RAP should have similar characteristics to mixtures...
