AADT and turning movements with triple checking and up to 1% average error.
Classified counts of vehicles, pedestrians and intersections for tariff calculation, contractual monitoring, impact studies and capacity analysis.
When to engage
Monitoring obligation
The concession has to report volumes regularly — and the AADT underpins the tariff calculation.
Impact study or licensing
The impact study requires recent, classified counts with a documented methodology.
Critical intersection
A traffic signal, roundabout or microsimulation requires a turning movement count by period.
Sub-services — Counts & Classification
Classified count (AADT)
Count classified by time, vehicle category and number of axles (lifted and rolling).
Pedestrian count
Pedestrian count for active mobility and urban projects.
Turning movement count
Turning movement count for traffic signals, roundabouts and microsimulation.
How we deliver
Definition of points and periods
Points, vehicle categories and counting windows according to the aim of the study.
Video recording
Filming of the points — the count is made on the video, which allows any period to be recounted.
Independent triple checking
Three independent counts of the same period: discrepancies are arbitrated and documented.
AADT and reports
Volumes by category and period, AADT and spreadsheets ready for the study.
What you receive
- Classified volumes by category, point and period
- AADT (annual average daily traffic) for tariffs and monitoring
- Turning movement matrices by intersection
- Spreadsheets and a report with the documented average error of up to 1%

Frequently asked questions
Through independent triple checking on the video recording, which brings the average error down to 1%.
We count by vehicle category, producing the AADT that underpins tariff calculation and the monitoring obligation.
Turning movement counts feed capacity analysis and microsimulation, and volumetric counts feed impact studies.
The video recording allows any period to be recounted — it is what makes the independent triple checking and the 1% average error possible.
The video recording allows continuous counting windows, including night-time periods, according to the design of the study.
