Modelling approaches for automatic transport

This work has concentrated on the development of models to describe the potential benefits of automatic transport. Such transport provides the opportunity to eliminate the need for a driver and thus opens up the opportunity to use far smaller vehicles. Several models have been used to provide improved understanding of these possibilities. Initial work on energy usage showed that current forms of public transport provided very limited benefits over private vehicles in terms of energy used per passenger km. However the use of small vehicles operating at low speed can provide a significant energy benefit. Further work has demonstrated the benefits of platooning.

More specifically it has been shown that approaches are available which would allow significant increases of capacity while retaining, or even improving safety levels over those experienced on current roads.

A final set of papers has evaluated a series of models examining the optimum form of transport in a city. Models of larger scale, less frequent transports were compared with models describing smaller scale more frequent transport. New general results for average trip length and other parameters have been discovered. Three very different models of automated transport have been evaluated. In all cases it was found that the smaller vehicles provided significant gains in transport efficiency.

Such systems can only be provided by approaches within the general Cybercar/Cybermove concept. The work therefore provides both a theoretical foundation supporting the Cybercar/Cybermove approach and a series of new results which can be used in further optimisation studies for application of Cybercars in the City of Tomorrow.
