        This article describes a solution of a complex information system for public transportation that provides control of dispatching, vehicles, depots and intelligent stops. This system has already been successfully installed and the Herman company keeps developing and innovating it. Now also a solution for integrated transportation systems is being prepared.

        A digital stop sign is a stop/station sign (hereinafter stop sign) either with a built-in information system containing public transportation vehicle departures or with an independent panel that is a part of the stop sign. Built-in stop sign LED panels are characterized by a small number of lines (1-4) and high LED density – diode spacing 4 – 5 mm. Digital stop signs usually have shorter readability distance (up to 15 m) which corresponds with the script size of about 3 cm.

  • Built-in graphic LED digital stop signs – the ELP 10x series.
  • Stop signs displaying arrival times – the ELP 13x series.
  • Stop signs supplemented with an information panel – the ELP 15x series.
  • Small graphic information stop LED panels – the ELP 16x series.

        Single color graphic LED information panels are designed to display both text information and graphic information. The demanded information or graphics can be displayed in variously defined “windows”. They are produced in various sizes and renderings. The LED surface of these panels is seamless with no spaces between lines. These panels always contain LED diodes of the same color (red, yellow, white and others on demand).

        Electronic station display panels (hereafter ELP) and systems are meant for informing (using images or voice) the passengers at the stops about arrivals, delays, departures of public transportation vehicles and about extraordinary transportation situations or other circumstances in the surrounding region. Up to date information is acquired from the dispatching department or other sources (e.g. induction loops, ISM band communication using the FHSS method).

        Is it necessary to use up to three SIM cards for data transfers in public transportation vehicles or is one SIM card enough? This article deals with the solution of this problem and with connections with a complex public transportation information system and also with the way of interconnecting these systems (dispatching, depots, stops, vehicles, passengers, and transportation technologies for the transportation itself). The article also describes individual types of communication and technology.
