Increased importance of public transport systems
Day in, day out, several hundreds of millions of people all over the world use public transport systems. Within a metropolis, this is usually the only cheap and efficient way to get from one place to another. Considering the rapidly escalating individual automobile traffic and congestion in big cities, public transport systems appear as an increasingly attractive alternative, and this trend poses a major challenge with regard to the existing infrastructures.

This evolution makes new demands on the rail-bound mass transit:

  • Growing metropolises require increased transport capacities
  • Fatal and serious accidents call for higher safety levels
  • The passengers expect enhanced safety and convenience
  • To increase the efficiency and reliability of their transport systems, metro operators switch to automatic and driverless train system requiring automated safety barriers.

Platform screen doors are thus absolutely essential in order to safeguard the security and comfort of the passengers.

The principal advantage of "Platform Screen Doors (PSD)"
Full- and half-height platform screen doors (PSD) ensure safe separation of passengers from the danger of falling on to the railtrack.

  • Enhanced safety: A separation of the platform area from the dangerous track zone offers the passengers optimum protection from arriving and/or passing trains.
  • Increased convenience: Passengers are protected against pressure waves. Air-conditioning systems can operate more efficiently. PSDs offer the metro operators additional information and advertising surfaces for a direct communication with the passengers.
  • Improved reliability and punctuality: The pedestrian flow on the platforms can be channeled and controlled according to the requirements, which results in shortened stopping times of the trains. The punctuality and reliability of the transport system are enhanced.
  • Increased train frequency: Shorter intervals between the arriving trains increase the transport system’s capacity.
  • Enhanced economic efficiency and profitability: The energy costs for the air-conditioning systems in the stations can be reduced. Consequential costs caused by accidents and other occurrences can be prevented by a PSD.
  • No more jostling on the platforms: The presence of a PSD confers a sense of security to the passengers; as they instinctively feel protected against the risk of being pushed into the track area, they are encouraged to use the full platform width.
  • More attractive stations: PSD systems distinctly change the passengers’ spatial perception and therefore exert a direct influence their personal sense of well-being. A wide range of options with regard to color and material selection, interior lighting, communication media, etc., are available, allowing the planners maximum freedom when designing the interior architecture of a station.
