Luminous platform

If you are really right, you see when the light is on!

When passengers wait for the S-Bahn lines 1, 2 and 3 at platform 2 in Stuttgart-Bad Cannstatt from the beginning of  2018, they will see colorful lights flashing. Illuminated symbols indicate where the train stops and show the exact positions of the doors shortly before the next train enters the station. Passengers are thus always in the right place at the platform, boarding is faster and the S-Bahn can leave on time.

In a six-month pilot operation, Deutsche Bahn tests the nation's first dynamic route guidance system with light strips at the S-Bahn Stuttgart. The innovative solution is based on light fiber concrete developed by the Berlin start-up SIUT.

The platform on track 2 in Bad Cannstatt is fitted with light fiber concrete behind the security strip at a distance of about 200 meters, one meter from the edge of the platform.

• The maintenance-free light strip consists of 670, eight centimeter thick and 30x30 centimeter wide light fiber concrete slabs.

• Fiber optic concrete contains 15 different components. These enable the light fiber systems to connect to the concrete without loss of quality.

• The slab surfaces are sealed so that they are protected from penetrating water, dirt and damage.

 Below each fiber optic slab is a small computer that can send and receive digital signals.

• The electronic is composed of a control board and a LED board, three times equipped with the colors red, green and blue, which can be interconnected to different mixed colors.

• Each individual fiber optic concrete slab can be individually controlled.

• Train type and train length are transmitted iin real-time to the optical fiber concrete slabs to display the train length and door positions.

• Symbols can be displayed, static or pulsating in the colors white, yellow, red and green.
• The holding position of the trains is indicated by a static yellow double line. Outside the holding position guide white pulsating arrows towards it.
• The door positions are marked by a static white double line.

High volumes of traffic can lead to delays in the processing of trains.
• Passengers do often concentrate at the platform entrances. This can lead to a delayed entry at busy doors.
• Passengers are often not at the right place on the platform where the train stops.
• Longer entry times can affect punctuality.

Easier to find place

From the beginning of 2018, the innovative passenger guidance system with optical fiber concrete will also display the occupancy rate of incoming trains in real time. The solution is based on a load measurement System developed by the English start-up OpenCapacity. In the first three moves data protection patterns are generated from the video recordings in the trains. The information on how heavily the individual cars are occupied is transmitted to the platform edge and displayed in traffic light logic.

The English start-up OpenCapacity develops for DB hardware and software, which determines the utilization of the wagons in real time based on data of the video surveillance in the trains. The British founders participated in 2016 in the network event "meet @ mindbox" of Deutsche Bahn.
• An additional on-board computer is connected to the video surveillance system in the S-Bahn trains.
• The computer records and determines an assignment pattern in real time using learned algorithms.
• This is used to calculate the occupancy rate, which is transmitted to the platform edge, which uses red, yellow and green illuminated double-lines to show in real-time how busy the wagons are.
• Passengers can easier find free places
