Manual Review in Traffic Video Analysis

Short answer

Manual review applies project rules to real-world ambiguity: turning paths, road-user overlap, class definitions and source limitations.

Before the project starts

• Agree the observation matrix and class dictionary.
• Define exception and escalation rules.
• Check the footage is suitable for the requested detail.

Practical approach

Analysts apply the same documented rules across locations and intervals, then reviewers check coverage, logic and output consistency. This avoids claiming certainty where the source does not support it.

Checks and limitations

Review ambiguous, high-flow and limitation-prone periods using the approved project rules.

Manual review is only as reliable as the brief, source visibility and documented quality process.
