Service summary
Origin-destination surveys describe agreed movements between defined source points, destinations, routes or screenlines.
When it is used
Use them for route, corridor, network and access questions that require movement relationships.
Methodology
Set origin/destination definitions, lawful collection method, timing, matching rules and aggregation before work begins.
Inputs and source requirements
Provide study area, source points, periods, privacy/security instructions and target OD format.
Movements and classifications
Represent movements only where the approved method can lawfully and reliably establish them.
Time intervals
Synchronise site clocks and matching windows before processing.
Typical deliverables
Aggregated OD matrices, method notes, coverage/exception information and quality record.
Quality control
Check time alignment, duplicate treatment, aggregation and unknown matches.
Limitations
An OD survey reflects defined source coverage and matching rules, not every trip on a network.
Privacy and security
Personal and registration information is never published; secure handling is project-specific.
Frequently asked questions
Can OD use video?
Yes, where the locations, timing and visible movement cues support the approved method.
Is it a complete network model?
No. It describes the defined sites and periods, not every trip in the network.
