Service summary
Link counts measure directional volumes and agreed classes on a defined road section.
When it is used
Use it for corridors, route assessment, transport modelling inputs and access studies.
Methodology
Define the count line, directions, road-user classes and treatment of adjacent access movements.
Inputs and source requirements
Provide a count location, travel directions, dates, periods, classes and desired reporting interval.
Movements and classifications
The service normally records directional passage across the count line rather than junction turning paths.
Time intervals
Retain requested interval detail for peak and directional comparison.
Typical deliverables
Directional interval totals, classification splits where scoped and location notes.
Quality control
Check continuous coverage, directional coding and total reconciliation.
Limitations
A link count does not explain route origin, destination or turning behaviour without further data.
Privacy and security
Only secure approved methods are used for project sources.
Frequently asked questions
How is a link count different from a TMC?
A link count measures passage across a road section; a TMC allocates movements through a junction.
Can it be classified?
Yes, if the source and brief support the requested classes.
Can a link count cover a multi-lane road?
Yes. The brief should identify directions, lanes or lane groups and the count line.
Does a link count show origins and destinations?
No. Origin-destination or route-choice work requires an additional study design.
