Representing the road infrastructure in open traffic

Abstract

In this paper we focus on the design of network objects for all types of assignment methods, varying from macroscopic assignments to micro simulation models. The basic idea is that the model environment should allow the simulation of traffic at multiple scales, based on standardized data formats. We derive the data requirements from an analysis of driving behaviour. Apart from the functional requirements, we propose a data format that aligns with to an existing international standard for geoinformation, i.e. CityGML (Geographical Markup Language for city and landscape models). Based on the requirement analysis we present a shortlist of objects and their characteristics that should be part of the description of the road infrastructure in simulation models. These objects have been implemented in the Open Source traffic and transportation model environment “Open Traffic”. Open Traffic offers the utility to transform the road infrastructure into logical networks for traffic simulation and assignment at various scales.Transport & PlanningCivil Engineering and Geoscience
