Who is… Daniel Kerwien?
For more than 25 years now, Daniel Kerwien has been working for Gauff Consultants in the most various transport planning projects, both in Germany and abroad. One year ago, he assumed project management responsibility in the IT Solutions department of Gauff Mobility Solutions. During the 1980s, he studied at the University for Traffic/Transport Engineering in Dresden specialising in the field of rail transport technology. Presently, Daniel Kerwien is responsible, among other projects, for the introduction of an Advanced Driver Assistance System (ADAS) in the scope of the DatNet application, a Gauff Mobility Solutions product that is presently being provided for numerous rail transport companies.

Gauff Consultants to equip railway companies with Advanced Driver Assistance System ADAS
The application of the ADAS system is based on the common approach to use the product DatNet, developed by Gauff Mobility Solutions, together with the ADAS system, an application that has been developed by the Institut für angewandte Verkehrstelematik GmbH (Institute for applied traffic telematics – intelligent transportation system – INAVET) in Dresden.
The following expectations are met with the introduction of the ADAS:
- Easy and individual driving recommendations and information provided to the engine driver with regard to energy needs
- Energetic optimisation between two stops and on the entire itinerary of the train
- Smoother procedures for all railway operations
- Optimised used of driving time reserves
The ADAS application is based on a sophisticated algorithm, which guarantees an energy-optimised driving mode between two stops always adhering to timeliness requirements. Energy savings can be achieved when forecasted arrival is sooner than scheduled arrival since this particular constellation allows an optimum distribution of available driving time reserves for each individual journey. The algorithm determines the optimum switching moment between the two driving regimes acceleration and traction switch-off (run-out). Recommendations for the driving staff are displayed on the Tf-units, available in the train vehicles, via a special ADAS application.
Between the stops, the precise arrival forecast for the next stop, which has been calculated by the ADAS, will be displayed. In the event of an unscheduled stop (e.g. due to a signal), the forecast will be updated on the grounds of infrastructure and train vehicle data available in the ADAS.
During this process, operation-specific requirements will be taken into account, such as delay allowance, important stops, train crossings, request stops, etc. The collection of infrastructure data is made by precise measuring runs with traction vehicles prior to the commissioning of the system.
The use of the ADAS system is possible both on diesel-operated vehicles and on electrified lines. In the second half of 2016, the system was provided for the entire railway network of the cantus Verkehrsgesellschaft mbH/Kassel. Presently, the system is being introduced in the network Mitte of the NBE nordbahn Eisenbahngesellschaft mbH & Co. KG/Hamburg.
The Advanced Driver Assistance System leads to considerable savings in terms of energy costs, it reduces prior-to-schedule arrivals and delays in the train operation thus having a positive effect on penalty fees imposed by the client. In addition, the system leads to a decrease of maintenance costs by reducing vehicle wear.
