Canadian Capacity Guide for Signalized Intersections
The Guide provides a set of techniques that can be applied to operational, design and planning problems at signalized intersections. The operational procedures deal with a detailed assessment of operating conditions within a relatively short time frame when all factors are known or can be reasonably estimated. The design process is used to determine specific control parameters and geometric features of an intersection that will meet desired design objectives and performance criteria. Planning techniques, often called functional design, are useful for longer range problems, assisting in the determination of the type of the facility and its basic dimensions. The basic method remains the same for all three application types, but the level of detail varies. Wherever possible, the Guide utilizes formula-oriented techniques that can be applied both in manual calculations and computer programs, including spreadsheet tables. Although advanced simulation and other computerized techniques may prove to be superior to formulThe Guide provides a set of techniques that can be applied to operational, design and planning problems at signalized intersections.

The Guide allows the evaluation of existing or future intersection control or geometric conditions relative to travel demand. It does not deal directly with broad systems or network issues, such as transportation demand management or congestion management. The results of the procedures included in the Guide, however, can be used as information for the evaluation of the impact of intersection control, or geometric alternatives on system aspects, such as population mobility, accessibility of various destinations or land use strategies. Although safety is an integral part of all traffic considerations, the Guide does not address this broad and complex issue explicitly. It is left to other specialized documents. Similar to the First Edition, the new version of the Guide concentrates mostly on urban applications. Although the procedures focus on fixed-time signal operation, advice is provided for their adjustment to the design and evaluation of traffic responsive signal control, including the traffic actuated method.
