A-26 Method Selection for Travel Forecasting: User Guide Long Description Tour frequency models can be implemented as a component of an activity-based travel modeling system, or as a stand-alone component of a tour-based modeling system. The key difference between a tour-based modeling system and an activity-based modeling system is that an activitybased modeling system explicitly recognizes temporal and spatial constraints on the generation and scheduling of activities.
