Dynamic signage, also called digital or electronic signage, is signage whose message can be changed remotely or automatically, using LED, LCD or similar displays, so it can show live information such as available spaces, closures, directions and rates.
In parking, dynamic signs are the visible end of a data system. Counts come from a parking guidance system, space sensors or the PARCS entry and exit counts; rates can come from the pricing system; messages can be scheduled or triggered by events. The sign is only as good as the data and the rules behind it.
Where it is used
- Street and approach. Count signs on the approach tell drivers which facility has space before they commit, reducing cruising.
- Entry. Shows spaces by level or zone, rates, full or closed status, and event messages.
- Inside the garage. Level and row counts, and arrows that change to route drivers to open areas. See wayfinding.
- Pedestrian areas. Elevator lobbies and pay stations can show messages, notices and, in some facilities, advertising.
What makes it work
- Accurate counts. Count drift erodes trust fast. Plan regular reconciliation and sensor maintenance.
- Legibility. Character height, contrast and message length must suit approach speed and viewing distance. See legibility.
- Message rules. Decide in advance what each sign says when a level is full, when a sensor fails, or during an emergency.
- Integration. Signs should draw from one source of truth shared with the PARCS, guidance system and apps.
Considerations
- Local sign codes may limit brightness, animation and changeable copy facing streets.
- Advertising on screens can earn revenue but competes with wayfinding for attention.
The Parkonomics view
Dynamic signs are cheap compared with the stall-hunting they prevent, but only if drivers believe them. Budget for the data, not just the displays: counting, calibration and someone responsible for what the signs say when things go wrong.
