Practical Examination of Traffic Accommodation Strategy Design Standards in Alberta

The Province of Alberta has begun the construction of Stoney Trail, which will serve as the City of Calgary's ring road once all four segments (NW, NE, SE and SW) are completed. The segment currently under construction is known as South East Stoney Trail (SEST). The project includes 14 km of new freeway and 13 km of upgrades and expansions. Associated with the project, a total of 9 interchanges will be constructed or upgraded. Traffic Accommodation Strategies (TAS) temporarily divert existing traffic during construction to accommodate site activities, at the same time ensuring worker and traveller safety. Various jurisdictions and organizations have published standards and recommendations for TAS design and implementation. While these publications are similar in some cases they can differ greatly from each other in certain critical areas. On the SEST project, the differences at times have become a significant issue. This paper examines various published standards and recommendations applicable to Alberta in order to identify and analyse the similarities and discrepancies between them, such as sign usage, spacing, taper lengths, delineation, lighting requirements, work area protection, etc. The standards are then compared to the practical experience gained on the SEST project to determine any deficiencies in the published material. Finally, attempts will be made to rationalize and streamline the process with recommendations for a practical approach in situations where conflicting standards are in-force.
