The time choice determines the start time of the main activity of a tour. This allows scenarios to be modeled that lead to time shifts. Examples of this include, in particular, time-varying measures such as a toll that is only collected during rush hour, increased frequency of public transport services in the morning, or temporary freeing of highway hard shoulders. The time choice for the main activity automatically influences the start times of all other activities on a tour. To avoid unrealistic execution times, Visum’s ABM uses the concept of opening hours: a tour can only be selected in such a way that all activities on the tour take place during the corresponding opening hours.

Note: The start times of the secondary activities as well as the start times of the trips and their duration are always recalculated, regardless of whether the option Start time of main activity executions is active. |
