This paper describes the model simulation of a Personal Rapid Transit (PRT) network for the project of a \“carbon neutral” town. The challenges faced were many: a new, largely unproven technology, a high number of stations, and a very concentrated peak demand. A mixed approach was used for the simulation: a \“traditional” static model for the simulation of large scale effects and a dynamic model with new software specifically designed to simulate PRT systems. The final model was a combination of modelling and forecasting techniques. Several scenarios were tested, the results of the modelling runs allowed to define the performance of the system, a metric for the Level of Service (LoS) of the PRT system as well as a Group Rapid Transit (GRT) strategy to cope with peak demand. The first lot of this PRT system is now operational: it is the first PRT system in the world in commercial operation.

The initiative was daring and the task challenging: a town for 50,000 inhabitants and business activities that would not generate carbon dioxide nor waste. Energy should come entirely from carbon-free, renewable sources, water and waste should be recycled and reused. All the comforts of a modern lifestyle should be guaranteed to residents and workers. Systematica (www.systematica.net) was invited by a major European architecture firm to submit a bid; our role was to define a transport strategy that would respond to the severe and exacting requirements of the tender.
