The Canadian capacity guide for signalized intersections includes techniques which allow to analyze different situations and intersection configurations. This second edition emphasizes the importance of a clear definition of the objectives of signal operation at a specific location. It also provides an understand of the role that the intersection plays in the travel patterns, public transportation, and both motorized and non-motorized modes transportation. The Guide provides a set of techniques that can applied to operational, design and planning problems and focuses the movement of traffic flow units, such as cars, trucks, transit vehicles, cyclists, and pedestrians at signalized intersections. With the assistance of this Guide it is possible to assess a vari of solutions using a set of practical evaluation criteria. Analytical and evaluation methods, and a set of numerical paramet for Canadian conditions are provided to estimate intersection capacity, quality of service provided and potential impacts. (A)
