Modern transport infrastructure takes advantage of LED technology as well. Large LED digital video and information boards, guidelines and active road signs are usually installed on busy highways, at crossroads and interchanges, on the way to railway and bus stations, airports and in any place where intensive automobile or human traffic is intersected. They can be used both for information and advertising. Usually video screens and all-purpose digital boards represent information about weather and road conditions, transfers, schedules, bookings, departures and arrivals. Such useful information draws people’s attention and strongly increases the advertisements’ effectiveness. Due to their large size LED screens ensure substantial audiences are reached. The possibility to insert bright and dynamic advertising messages into information blocks is an undisputed advantage of LED display solutions as opposed to conventional information boards.
