PALOS-PK Vehicle Count Sensor

More than 99% accurate.Inbound and outbound vehicles are correctly counted.The system ensures accurate counting even when several vehicles pass in opposite directions, side by side, in the wrong direction, or even bumper to bumper.


Counting method

The PALOS-PK Vehicle Count Sensor system uses an infrared sensor installed in the ceiling over the lane to detect and count vehicles passing underneath.
A single sensor is able to count vehicles passing in opposing directions with a high accuracy even in difficult conditions, such as in traffic jams or when a vehicle passes in the wrong direction. In addition, accurate counting of each vehicle is possible even if several vehicles pass side-by-side or in opposite directions.
It should be noted that people, carts, and two-wheeled vehicles other than cars are not counted.

Ensuring accurate counting even in traffic jam

Because it can correctly detect vehicles even if they are traveling in a row or if they have stopped, PALOS-PK is able to provide accurate parking availability.

Accurate counting is possible even if a vehicle remains under the sensor for 30 seconds or for several minutes. High accuracy is also ensured even if the distance between vehicles is short.

other than cars
PALOS-PK 60 min. A vehicle that is stationary for a long time can be detected with Giken Trastem's detection method. As responses from multiple devices are used for detection, it is possible to identify individual vehicles even if the distance between them is short.
Loop coil x The broad detection range prevents accurate counting when the distance between cars is short. For inspection and repair at the time of failure, complete removal may be necessary in worst case scenarios. Some models do not support detection of vehicles stationary for a long period of time.
Photoelectric tube x Objects other than cars are also detected during consecutive counting. If two units are used in order to exclude people from the targets, detection becomes inaccurate with traffic jams. Also, malfunctions may occur depending on the vehicle shape.

Supporting multiple lanes and multiple-point turns

○ Supports wide roads with two or more lanes.
○ Detects two-point turns at car parks.
○ Excludes people and bicycles from the target, and is not subject to the effects of wind or ambient light.
○ Counts vehicles and outputs vehicle detection separately.
*Can be used as a proximity signal for ticket and payment control.

Loop Coils (LC) and Photoelectric Tube

Loop coils and photoelectric tubes are basically used for a single lane and do not support multiple lanes.
In addition, several devices would be necessary to detect different directions.

Loop Coils

An error may occur when two vehicles pass side by side or while passing each other. If a loop coil is installed in each lane, an error will occur when a vehicle drives in the center of the two lanes.

Photoelectric Tubes

Objects other than cars can be detected, but cars cannot be detected correctly when passing each other.
