Idealized Models for Public Transport Systems

The goal of this paper was to describe public transport based on future automatic transport, for example, cybercars or personal rapid transit; however, none of the models used presume automation and it is believed that, in transport terms, the results are equally valid for driver operated or automated systems.The two models used are based on idealized systems meeting uniform trip demand patterns. The models use, a simple line corridor and a more complex synchronous network. The network system proposed may have value in its own right, but is introduced as a model system to enable the effectiveness of meeting transport demand with transport networks of different size to be calibrated. The results for both models were very similar. Minimum trip times, including walk, wait, in vehicle and transfer elements, were found to occur with a station separation of around 0.5 km. Maximum average speed was about 15 km/h. The results demonstrated that transport effectiveness increased with reducing vehicle size. Optimum vehicle size for 0.5 km was projected to be seven passengers. This would require automatic control to be operationally effective. This makes a case for consideration of small automatically controlled vehicles for public transport.
