Daily life is the sequence of activities in which persons participate at specific times and places. The movement between the activities and locations is the traffic. The trips are therefore not independent, but form an interdependent chain, which is the result of an explicit time- and path choice. Current transport policy is directed at these choices through the provision of information, road pricing or changes in the time-space regime.
This study tries to answer the following important questions:
What is the state-of-the-art in activity based models?
How can Swiss practice profit from these models?
Which are then the primary research topics in this area for Switzerland?
The literature review showed, that the activity-based approach uses a wide range of methods and theories. The empirical work provides insight, for example, into activity patterns, into activity scheduling or into the interactions within the household or the social network. Three main modelling approaches were identified, which are often used in combinations:
- Random utility maximising models (normally implemented as logit-models)
- Computational Process Models (CPM), which employ rules to describe choice process
- Microsimulation models
