Requirements for Traffic and Transport Models

To include economic and commercial interactions in traffic and transport models additional objects and aspects have to be included logistical cause-effect relationships, additional stakeholders (e.g. freight forwarder), additional markets (e.g. distribution logistics) and additional instruments to control economic and commercial traffic (e.g. restrictions of access, delivery time slots, etc.). For modelling these objects of economic and commercial interactions standardized approaches are missing in Germany and abroad—there is a gap in the “toolbox of traffic modelling”. There are several model ideas, but both the contracting authorities as well as the modellers in practice usually do not have an overview of the existing approaches, a recommendation of the aspects to be considered and named requirements, which economic transport models should achieve. In this contribution the requirements will be described and explained with reference to examples. The examples are taken from existing and hypothetical models for private and commercial transport.
