Free-space signs that tell drivers exactly where to go.
Slot Guidance counts every free bay with sensors or cameras and updates signs at the entrance, ramps and aisles within seconds. Drivers skip full levels and find a space on the first pass.

What it does
Built for the lane, the level and the control room.
Bay sensors or overhead cameras
Ultrasonic sensors for covered floors, or cameras that each watch 6 to 8 bays on open decks.
Level and aisle signs
LED counters at the gate, every ramp and every aisle, plus red and green bay lights where fitted.
EV bays
EV bays are counted on their own and can be linked to charger status.
Accessible and women-only bays
Reserved bays near lifts are counted and shown separately, so they stay free for those who need them.
Two-wheeler zones
Separate counts for two-wheeler areas, with signs to send bikes to the right basement.
Live map in the control room
Every bay on every level, colour-coded, with the option to block bays for events or maintenance.

On real sites
How Slot Guidance is set up at different car parks.
Sensors or cameras: which is better?
Sensors suit covered floors with low ceilings. Cameras are cheaper per bay on open decks. Many sites use both.
Can we block bays for an event?
Yes. Block any bay or zone from the control room, and the signs adjust their counts at once.
Do the signs work if a sensor fails?
A failed sensor is flagged in the dashboard and excluded from counts, so signs stay accurate.
