Including pedestrian and bicycle traffic into the traffic simulation SUMO

Being available since 2002, the open source traffic simulation SUMO has gained a state of being accepted by a large community. Albeit SUMO allows to model inter-modal trip chains for individually simulated persons it still lacks models for the dynamics of pedestrians and bicycles as well as for the interaction between these traffic modes and motorised traffic. Closing this gap is one of the tasks scheduled within the COLOMBO project. This paper outlines the requirements put on a pedestrian model, list available prerequisites that are used, and show currently followed approaches for implementing pedestrian models into SUMO.
