Including Right-of-Way in a Multi-Modal Large-Scale Traffic Assignment Model Suitable for Bicycle-Dense Areas

Abstract

Intersections are typically responsible for a substantial share of the total travel time in urban areas, especially with the presence of mixed traffic. Nevertheless, delays caused by yielding for cyclists at intersections are typically not modelled in large-scale traffic assignment models. This study proposes, implements and applies a computationally efficient methodology for modelling delays caused by conflicting movements at multi-modal intersections. Nodes representing the intersections are classified into three node types which process potential movements across nodes differently. A large-scale case study carried out in the greater Copenhagen area simulating more than a million bicycle trips shows reasonable computation times and sensible added travel times for cyclists. Future work before the conference involves a rather straight-forward implementation of traffic signals as well as resolving an issue leading to unrealistic long delays for a small subset of car trips.
