If there are no delay or extend settings, the zone will remain activated until all cars have

exited the zone.

Counting Channel

A counting channel counts each vehicle that passes through the zone. e channel is acti-

vated once the middle of the vehicle crosses the leading edge of the zone (see Figure 8.8).

Note

If you use a counting channel, you need to position the zones so that the vehicle is

detected and tracked before it arrives at the zone. Also, fast-traveling vehicles may

not be counted as accurately as slow-moving vehicles.
