Description

The purpose of this guide is to promote uniformity for highway design in Alberta and to encourage the provision of safe and efficient roads for the well-being of the travelling public and society in general. The guide establishes uniform geometric design standards and procedures to carry out the highway design functions of Alberta Transportation. The Highway Geometric Design Guide is currently in the process of being updated and will be published upon each chapter completion. Should there be any contradiction between chapters that have not yet been updated and the new chapters, the information found in the updated chapters shall take precedence.

Description

This Bulletin is issued to inform practitioners of the department’s guidelines on the use of High Tension Cable Barrier (HTCB) installed in the median and on the roadside (or right hand side in the direction of travel) of the roadway. Cable barrier has been proven to effectively prevent or reduce the severity of median cross over crashes and run-off-road crashes. HTCB installed at median and roadside locations has been shown to be the most forgiving barrier system available for reducing the severity of run-off-road crashes in many applications.
