The Numeric Message Sign (NMS) indicates the number of available parking bays in a specific zone or level, allowing a driver to make a pre-emptive decision as to whether they want to park in that zone or level before they enter. The indication of occupancy can be improved either through the use of a circle/cross, or arrow/cross enhancement to the NMS unit. The NMS receives its configuration and commands from the IdentiPark software and can be either powered from the IB along the sensor bus or from a mains power source.
