Note: This function is only available if you have activated the Tour-based demand model add-on ( Enabling or disabling add-ons). |
The following step-by-step instruction illustrates the typical work flow for demand calculation with the help of the Tour-based model (Fundamentals: Activity chain based model (tour-based model)).
1. Construct the network model (transport supply) (Editing the network).
2. Create zones (Creating a zone).
3. Connect the zones to nodes in the network (Creating a connector).
4. Create a demand model, activities, activity pairs, activity chains, person groups, structural properties and demand strata and define their properties (Managing demand objects).
5. Enter zone attributes: population figures by person group (Editing the number of persons in a person group), the values of the strucutral properties (Editing structural property data) and the values of zone-specific procedure parameters (Editing values for non-constant mobility rates and study area shares), if required.
6. Define the exchangeable modes (Properties and options of modes).
7. Specify a procedure sequence consisting of the following steps: Tour-based model - Trip generation and Tour-based model - Combined trip distribution / mode choice (Setting up and starting the procedure sequence).
8. For each procedure, set the parameters.
9. To the procedure sequence, add procedures for skim matrix calculation (Calculating PrT skims and Calculating PuT skims) and, if required, for assignment and iterative repetition of the procedure sequence (Starting the iterative repetition).
10. Start the procedure sequence (Executing procedures in the procedure sequence).
The demand is calculated using the tour-based model.
