10.5.2 Direction logic „Parking Bay“
This direction logic is used for short entrances and exits. This logic suppresses compromising of the count
by cross-traffic on Loop 1. This means it is non-critical whether Loop 1 is placed in the passing lane or in the
maneuvering area.

The placing of the loops depends on which travel direction backups are anticipated in. In travel direction 1 →
2 no backups are permitted! In travel direction 2 → 1 even vehicles in traffic line situations are correctly
counted, whereby the vehicle gap must always enable a loop.
Logic for travel direction 1 → 2
• The counter pulse arrives when both loops have been fully traversed
• Correct count for individual vehicles
• Correct count for maneuvering as well
• Traffic jam situation and traffic lines may not occur for travel direction 1 -> 2!
Logic for travel direction 2 → 1
• The counter pulse arrives as soon as Loop 2 is left in the direction of Loop 1
• Correct count for cross-traffic as well
• Correct count for traffic lines
• Correct count even for maneuvering of a single vehicle
• No maneuverers are allowed within a traffic line!
