Beamways AB has the ability to perform different types of PRT studies for cities and city areas. The studies are based on Beamways’ deep knowledge of PRT technology with its inherent ability to solve transportation problems in our cities.

Network design and simulation

Using the BeamEd software Beamways can design and dimension PRT networks based on map information. This work will need assistance from the customer when it comes to knowledge of local conditions. BeamEd can be configured to simulate the parameters of different vendors’ PRT systems which allows comparisons of different implementations of the designed network to be made.

When a first version of the PRT network is finished a preliminary simulation can be performed. This simulation does not use information of the real demographic conditions of the area, but just assumes that housing and work places is evenly distributed among all stations.

To improve the accuracy and to find bottlenecks and over-specified network parts more easily demographic information from external GIS systems can be added. With this additional information a more realistic simulation can be performed. Thanks to the high performance of the simulator it is easy to modify the network and the dimensioning of the stations to optimize the system.

To further enhance the simulation results it is possible to export travel time data from BeamEd and use it in external software to perform mode split calculations. This gives more accurate results when it comes to the PRT system’s ability to attract passengers.

Economic studies

Beamways has developed a model for economical analysis of PRT systems. This model can be used on its own or with a network designed and simulated in BeamEd. If no specific network has been designed you can estimate network size and ridership numbers using an estimation function based on a few key figures like the network area size and the population of the area. This estimation has been calibrated using a number of networks designed and simulated for different cities.

The economic model contains a business part and a socio-economic part. The busniess part calcalates the expected outcome for the operator under selectable conditions. These conditions include ticket fares, operation and maintenance cost, amortization periods etc.

The socio-economic part contains a CBA (cost benefit analysis) study which today is adapted to the methods used by the Swedish railroad authority, and with the official list of CBA values (ASEK) used in Sweden for instance to valuate travel times, environmental disruption and traffic accidents. In addition to these factors the model also valuates public health effects. The CBA model has been verified by researchers at the Linköping University.


Beamways has performed a long term study of a large PRT network catering for all local transit needs in the City of Uppsala, Sweden, 180 000 inhabitants. This study was performed by mid-year 2009, and was commisioned by the City itself.
