Traffic counts for design engineers, developers and road authorities

The project calls for a traffic count. Today it’s done by a person with a clicker.

A traffic study rests on a single figure: how many vehicles and how many pedestrians pass a point, per interval. That figure is usually obtained by two or three operators who stand in the field for a few hours and count by hand. We take it from video recordings: the same intervals, the same methodology, but the count can be redone at any time, on the same footage, by anyone.

Illustrative figures. In a real study, the intervals and approaches are set by the design brief.

Why the method matters

A manual count can’t be checked a second time.

When a study’s figure supports a permit, a parking lot or an intersection, it ends up being challenged. And if it was obtained with a clicker, there’s nothing to recheck: the operator has left, the day has passed, only the table remains. On video, the count can be redone on the same footage, at any time.

Re-checkable

The figure has a recording behind it.

If someone challenges the values, the interval is reopened and recounted. Same hour, same footage, same result — or a correction everyone can see.

More hours

Not just the assumed peak.

An operator tires after a few hours, so short intervals are picked around the assumed peak. A camera keeps going all day, so the real peak isn’t assumed, it’s measured.

More points

The same day, in several places.

Manual counts at different points are usually done on different days, which makes comparing them questionable. With cameras, the points are measured simultaneously.

What we don’t doWe don’t read license plates and we don’t identify people.

A traffic study needs no personal data at all: what matters is how many vehicles of each category and how many pedestrians pass through a section, per interval. License plates, faces and identities are not part of the deliverable and aren’t needed for the methodology. This is the only area of our work where Law No. 195/2024 doesn’t come into play at all.

What you get at the end

A table by interval and the recording that backs it up.

The deliverable is built to go straight into the design report, not to look nice on a screen.

01

Count table

Volumes in fifteen-minute intervals, for each approach and each direction of travel. Table format, ready to go into the appendix.

02

Vehicle mix

Cars, light commercial vehicles, trucks, buses, motorcycles, bicycles. Plus pedestrians at the crosswalks in the count section.

03

Peak hour, measured, not assumed

The day’s peak interval and the peak hour factor, calculated from all the measured intervals, not from the two hours someone spent in the field.

04

Flow diagram

The intersection diagram with volumes for each movement: through, right, left. The drawing you use when sizing the intersection.

05

Methodology note

What was measured, when, with what coverage, what was excluded and what the margin of error is. Without it, the figure can’t be verified, and a study that can’t be verified gets challenged.

06

The recording

The footage stays with you for the agreed period. If a challenge comes up, the interval is reopened and recounted.

How a study runs

From the design brief to the table in the appendix.

01

Points and intervals

Together we set the count sections, the days and the hours. The design brief says what needs to be proven; everything starts from there.

Setup

Where cameras already exist, we use them. Where they don’t, we mount temporary cameras on a pole or tripod for the duration of the count.

Counting

Automatic counting across all intervals, with a manual check on a sample: a few intervals recounted by a person, so the real margin of error is visible.

Delivery

The table, the flow diagram, the methodology note and the recording. If the design engineer asks for a different interval breakdown, it’s rebuilt from the same data.

no re-measurement

How accurate the count is

We don’t promise absolute accuracy, and we don’t believe vendors who promise it. At our reference installation we count daily with a parallel manual check, and the measured margin of error is published, not hidden. For a study, the margin of error goes into the methodology note.

Frequently asked questions

Questions from design engineers.

What exactly do I get at the end?

The count table in fifteen-minute intervals, by approach and direction; the vehicle mix by vehicle category; pedestrians in the section; the peak hour and peak hour factor; the flow diagram; the methodology note; and the recording, for the agreed period.

How is it better than an operator with a clicker?

It can be redone. A manual count can no longer be checked: the operator has left, the day has passed, only the table remains. On video, if someone challenges an interval, it is reopened and recounted on the same footage.

Do you collect personal data?

No. We don’t read license plates and we don’t identify people. The deliverable contains volumes by category and interval. This is the only area of our work where personal data isn’t an issue at all.

Do you need power and permits on site?

The temporary cameras run on batteries for typical counting periods. If the point is on public land, we obtain the placement permit together; it’s usually requested by the design engineer, not by us.

How long does a study take?

It depends on how many points and how many days the design brief calls for. Setup takes a day, the count runs as long as you’ve set, and the deliverable arrives within a few days of the count ending.

What accuracy do you guarantee?

We don’t guarantee absolute accuracy, and we don’t believe vendors who do. We manually check a sample of intervals, and the measured margin of error goes into the methodology note. A study without a methodology note can’t be defended when challenged.
