Smart city platform & mobile IoT traffic sign

A*Sign, world’s first mobile IoT traffic sign, communicating with Romcore Smart Cities, a platform for the request management, planning and tracking of digital signage.

The challenge

Nobody likes endless paperwork. Requesting and managing public spaces should be easy, quick and failproof. It shouldn’t take two weeks. Cities have a major problem in dealing with the massive amount of unauthorised use of street parking space.

City of Antwerp

Antwerp, with 520.000 inhabitants the largest city in Belgium. Thanks to the Romcore platform, it now successfully handles over 50.000 requests and permits a year.

Our solution

The A*Sign digital traffic signs are equipped with Sigfox, NFC, GPS and E-ink screens. They are an IoT add-on for the Romcore platform that handles every city user request:

  • Citizens complete their digital request in 2 minutes
  • Civil servants manage requests in a user-friendly interface
  • 2 supporting Romcore components handle asset management and planning

The number of public servants involved in the management of a single request dropped from 7 to 2. Less paperwork, more productivity.


Thanks to the automation of the request management, Antwerp now has 3 times as many approved permits and a much clearer real-time view on public domain usage.


As the amount of requests is multiplied by 3, city revenue increased equally.

The return on investment of A*Sign is spectacular. The number of regularizations has tripled in less than a year.
