A Flexible Platform Screen Door System which is Suitable for Different Train Types
In an always larger number of rail bound urban transport systems in the world the platforms of stations are separated form the tunnel by glass walls which give openings (mostly by sliding doors) where train doors open, when the train has come to stop in the station. These Platform Screen Doors (PSD) are also used to make Bus Rapid Transit lines safer (used in some large cities instead of metro systems).
Platform Screen Doors can prevent passengers from accidents with trains, but also make it possible to undertake driverless metro operation. They are very useful for increasing the comfort and safety level in stations. In cities of Asia platform screen doors make air condition in underground stations possible. In connection with the introduction of driverless metro operation, the investment into platform screen doors breaks even after some time into direct and indirect return on investment. The perception of a metro station with platform screen doors is better, cleaner and more safe.
Some metro systems have different trains stopping along the same platforms. Metroconsult has developed ways for solutions which can make it possible to retrofit Platform Screen Doors into existing metro lines with different types of trains. They can be built also into stations with artwork and special architecture in the stations without changing the character. Flexible PSD can be built into surface stations, underground stations with flat ceilings or with vaulted ceilings. Operation with different types of trains, variation of door positions in the rolling stock is possible.
Flexible Platform Screen Doors consist of a screen wall with only movable elements which open wherever train doors will stop along the same platform edge of a station. The elements of this flexible screen door system can be suspended from the ceiling of the station (door opening ca. 2,10 metres high) or can be only installed on the platform edge on the pavement without touching the ceiling. These half high flexible platform screen doors have door element heights form 1,50 metres to 1,70 metres.
The new development of flexible half high platform screen doors has been granted a German Patent on December 13, 2012. Further applications in other countries are ongoing.
System for passenger flow management
A Newly Developed Passenger Guidance System for Underground Public Transportation Increasing the Passenger Capacity of Stations and Metro Lines
The here presented system is related to the metropolitan public rail-bound transport, presenting a solution proposal that is able to result in quality improvements in any public transit system where a large number of people is transported.
In inner city transport systems, especially in underground railway stations, there are often negative effects by crowding and by problems of orientation. On the platforms of interchange stations, the passenger distribution is often very unequal in density, and it is evident that passengers in crowded underground stations are often not sufficiently guided.
In fastly growing metro systems, there is, additionally, need to increase the capacity of the nodal points - the junctions - of the system: The inner city or central stations of the metro systems, which have been built at a time when the number of passengers transported was less, now have to cope with a increasing number of passengers as soon as the systems grows. During the years of metro system growth, the metro lines become longer, and the passengers using the metro system and its central stations, become more. In this moment, there is lack of capacity in the smaller and older central stations.
With a newly developed combination of already known - and new -technical measurements, it is possible to increase the passenger capacity, the speed of interchange in metro stations, and the speed of the travel of the customers in metro lines, without the necessity of enlarging the built infrastructure.
By technical means, passengers can be counted, as well in trains as in the stations, and the density of the passenger stream can be egalized by displays indicating zones of moving, waiting, entering and leaving the train. The system is dynamic, it is reacting to the different and steadily changing situations in all stations along a metro line, taking into the process also the situation of the other lines in the interchange stations. As the system is able to put in order the process of entering and leaving the train, it results in cutting short the stop time ot the train by regardable time.
