Question
What decision should this evidence help someone make?
Scope
Which locations, movements, classes and periods matter?
Review
How will completeness and definitions be checked?
Output
What format will make the result easiest to use?
Short answer
A traffic-count camera should show the exact count line, approach, movement path or crossing that the study matrix requires.
Frame the decision
Start from the fields needed in the output. A camera that looks attractive but omits a slip lane, crossing or queue reference point is not suitable for that scope.
Balance view and detail
A wide frame can preserve context while a closer view may show class cues. Multi-camera arrangements are useful when one angle cannot show both.
Review before production
Inspect representative periods for glare, shadows, foliage, signage, parked vehicles, overlap and night visibility, then document the accepted coverage.
Frequently asked questions
Is there one ideal camera height?
No. The suitable position varies with site geometry, density, study type and classification detail.
Can a roundabout need multiple cameras?
Yes, when the central island, trees or geometry hides required entry-to-exit paths.
