Communication is crucial to the coordination and efficient operation of public transport systems. However, deployment of infrastructure based communication systems is expensive, esp. due to long-term operational costs. Delay tolerant vehicular networks are a promising alternative since only very few infrastructure elements are required. This paper presents a DTN routing algorithm for urban public transport systems which exploits the knowledge about system characteristics and node mobility to improve the routing performance. Various DTN routing schemes are compared with the presented algorithm. Moreover, the impact of disturbances on the routing performance is examined.
