Draw Lanes, The Count Line And Speed Lines

Traffic Monitor counts vehicles, measures their speed and watches each lane’s direction. You draw what it needs in step 3 of the camera flow (Add a Camera and Draw). The checklist beside the picture asks for:

• A lane for each direction, with its arrow.
• A count line or the speed lines: without a count line, vehicles are counted at the first speed line they cross.
• The two speed lines and the metres between them.
• Detection area (optional): vehicles outside it are ignored.

Step 1: Draw A Lane And Its Direction

1. Select Add a lane.
2. On the picture, click the lane’s corners, then two points along the direction of travel: the arrow shows it. Select Finish the shape.
3. Give the lane an ID, for example northbound (letters, digits, - and _).
4. Type the lane’s speed limit in km/h, for every class or per vehicle class. Speeding is reported above the limit; leave it empty for none.

Draw one lane for each direction of travel. A vehicle against the arrow raises a Wrong-way driver alert.

Step 2: Draw The Count Line

1. Select Add a line.
2. Click two points across the road, where vehicles are counted.
3. Give it an ID, for example count.

Step 3: Draw The Speed Lines

1. Select Add speed lines.
2. Click two points for the first line across the road, then two for the second, further along.
3. Type the distance between the lines in metres, measured on the road, for example between two lane-marking dashes. Speeds are estimates for traffic management, not for tickets.

Step 4: Add A Zone

1. Select Add a zone, click its corners and select Finish the shape.
2. Choose the zone type: No stopping (a vehicle standing there too long raises a Stopped vehicle alert), Plate reading area or Detection area.
3. The checklist ticks as you draw.

Step 5: Review And Save

1. The shapes: the lane, the count line, the speed lines with their metres, and the zone.
2. The checklist with every required item ticked.
3. Select Save the camera.
