The Prague Public Transit Company (DPP) is planning, for September of this year, further tests of a tram anti-collision system, this time from an Israeli company Mobileye. The tests will be performed on 15T tram type in the area of the Hostivař Tram Repair Shop. The anti-collision system should prevent rail accidents, i.e. in Prague transport accidents between trams as well as accidents with cars and especially collisions with pedestrians. It has not been fully implemented in the tram public transport yet. If the system is functional, further testing on selected trams in operation is expected.
„During the 4th and 5th of September, DPP installed the tram anti-collision system on 15T type trams of reg. no. 9286 and 9366. This technology was set up according to the DPP’s requirements for tram transport in Prague. Currently, the system’s testing and simulations of accident states are in progress in the Tram Repair Shop. If the system handles all scenarios of accident actions, the DPP’s technicians will firstly apply this system in testing operation without passengers. If the system corresponds to the submitted requirements, only then it will be released into operation with passengers. Drivers controlling these trams will be trained by a representative of the Israeli company and DPP will draw the information for the system’s further optimisation from their findings.
The system is based on a principle of smart cameras which register objects, vehicles, persons, their speed and direction of movement and work with special SW algorithms. The system itself “learns” to read the surroundings, thus becoming more reliable. The system must not place unnecessary burden to the drivers, but it must activate the acoustic warning in the case a collision is detected. If the anti-collision system holds good, then the subsequent technical step should be the implementation of the output to the vehicle’s driving system for new trams of 14T and 15T type. In the case of a collision, these tram types would then be able to brake automatically, without a driver’s intervention.
If the tram anti-collision system has been tested in operation by DPP without any problems, for the future DPP could purchase it, in a form of public competition, for all DPP trams (approximately 850 pcs). It could especially significantly eliminate collisions with pedestrians, thus preventing serious injuries resulting from a tram impact on a pedestrian, on which DPP draws attention also through the campaign called “Neskákej mi pod kola“ (“Don’t jump under my wheels”): https://www.neskakejmipodkola.cz/
