LED Parking Information Boards show motorists car parks with free parking places. They indirectly reduce vehicular traffic in smart city and reduce air pollution, provide information on the actual number of free parking spaces e.g. in the city center, side alleys, shopping malls, museums, office buildings or multi-storey car parks. Stanford’s research indicates that this is one of the most important conveniences in the center of the agglomeration, because most of us do not want to settle important matters and move by bus or tram. Dysten manufactures LED parking displays and LED electronic signs in many configurations.
