• PSItraffic Depot Management

    A clear overview of all processes

Our PSItraffic Depot Management System automates your operations and optimises your personnel and vehicle use.

Optimally dispatch drivers and vehicles.
For the best-possible utilisation of all resources.

The many challenges that a transport company faces can hardly be dealt with without the help of modern information technology. Ensuring daily operations, meeting growing passenger demands on quality and reducing costs – these are the daily challenges of transport companies. Fulfilling these requirements begins at the depots, where buses and trams are prepared for daily operation, cleaned, refuelled, sanded, maintained and repaired.

How can the garage tasks be integrated with the requirements of smooth operation? What maintenance must be completed and at what time? Which vehicles must be refuelled? Which do not? Is there collision damage to a vehicle? When does it have to be pre-heated in the winter? Which driver takes which vehicle in the morning for his trip, and where is this vehicle parked?

These and many other questions are answered automatically by the PSItraffic depot management system (DMS), which at the same time also organises the necessary operations.

With PSItraffic/DMS, you are provided with an overview of your operation and, in case of disruptions, can take prompt action. Whether in disposition, in the garage, or drivers searching for their vehicles – the optimisation potential is enormous. PSItraffic/DMS creates transparency and helps you to adapt processes and thus improve your competitiveness.

PSItraffic/DMS seamlessly integrates multiple depots and different business areas such as tram or bus.

Integrated components for efficient planning and dispatching

From entering the depot to departure: PSItraffic/DMS models all of the processes at the depot and transparently presents the current operational, garage, driver and vehicle situations.

Vehicle tracking
Tracking by radio allows the identification of the vehicles promptly upon their arrival and departure, and the determination of their locations in the depot. Late arrivals and departures are reported as alerts or warning. Vehicle locations are displayed in the system for the dispatcher and for garage employees and form the basis of their work.

Automatic parking position assignment
Upon entering the depot, the driver receives information on where to park the vehicle for refuelling or sanding, for maintenance, cleaning or repair work, or for the next departure. Daily shunting is greatly minimised, thus saving time.

Dispatching garage and supply tasks
PSItraffic/DMS schedules garage and supply tasks, or acquires such information from a garage system (for example, SAP, Maximo, COSware), assigns vehicles to service stations, and informs the garage and service employees and documents all completed work.

Provisioning of driver information
PSItraffic/DMS informs drivers about their shift, the vehicle location and condition, either at terminals or via mobile phones. Simultaneously, the system informs dispatchers about the on-time departure from the parking position and the departure from the depot.

Quality management
PSItraffic/DMS gathers historical operating data, analyses it graphically and in reports, and in this way forms the basis for analyses and process optimisations.

Automatic vehicle and tour assignment
Vehicles are parked in the depot so that the right vehicles are available for all subsequent tours. If a vehicle is not operational, a new disposition is made in real-time. If a tour cannot be filled because there are not enough vehicles available, a vehicle shortage is immediately reported in the system, and the dispatcher can act promptly. The basis for all optimisations is the industry-proven technology Qualicision® from PSI.

Your benefits

Plan, control and monitor bus and tramway operations

  • Transparency at the depots
  • Vehicle parking and assignment in real-time based on Qualicision®
  • Improved vehicle availability
  • Reduction of the vehicle reserve
  • Optimised vehicle supply (cleaning, sanding, refuelling)



  • Optimised refuelling
  • Manual, semi or fully-automatic vehicle dispatching
  • Use of standard interfaces
  • Integration with AVMS (Automatic Vehicle Management System)
  • Integrated quality management system (Business Intelligence System)

Software architecture with maximum flexibility

High usability

Even complex processes must remain simple to control. This is why the design and usability of interfaces and dialogues represent a special challenge for us.

  • Clear menu structure
  • Graphical and table views
  • Individual customisations and views
  • Comprehensive navigation functions
  • Multi-language user interface

Integration and openness

The use of standard interfaces and the creation of new standards make the exchange of data with existing IT systems secure and stable.

  • Standard interfaces for journey and roster planning, for personnel deployment and for maintenance/ERP
  • Sections, switches and gate control
  • Tracking
  • Fuel data system, mileage tracking
  • Automatic vehicle management system (AVMS)

Optimisation with Qualicision - Dynamic, flexible and fast

The dispatching core applied for the DMS is based on PSI's optimisation software Qualicision, which finds a solution based on operational constraints within seconds.

The special feature of Qualicision is not only its outstanding speed and thus the possibility of cyclical use at short intervals, but also the consideration of various restrictions and qualitative criteria. These can have different effects depending on the time of day and be configured differently for different depots.

The core of the optimisation itself calculates a solution across all depots based on any restrictions and qualitative criteria. The optimisation automatically recognises vehicle bottlenecks and adapts the allocation. So non-detachable blocks will be far in the future and thus there is sufficient time to react, for example by vehicles being provided ahead of time by the workshop.
Restrictions and criteria can be switched on and off online or configured on a time-of-day basis. In addition weightings can be configured so that individual criteria have a higher degree of target achievement than others.

The optimisation module has been successfully used by our customers for many years and will be an integral part of the even more complex requirements for charge and load management of alternative drives in the future and will serve the objective to have autonomous trips in tram and bus depots.
