Road traffic — Counting points — Département du Loiret — 2011

Geolocation of permanent and temporary road counting points accompanied by annual traffic indicators (TMJA all vehicles/% of heavy goods vehicles/truck weights)

**Collection context**

Knowledge of the total traffic to be flowed on a road (all vehicles combined) is essential in order to give the track geometric characteristics in relation to its importance and the speeds used, to draw up accident checks and to propose route or safety arrangements. It is also essential to calculate the road structure necessary for rehabilitation or development projects, based on heavy goods traffic.

**Collection method**

The departmental road network has been divided into homogeneous traffic sections. In addition to permanent stations, temporary counts are carried out by D2I teams each year to complete the road traffic base. Each year, nearly 500 meter installation and deposit have been carried out on a time-by-day basis. In order to consolidate and secure the road traffic base, it was decided to count at least once every 5 years the traffic of each section. The counting frequency is calculated according to predefined criteria.
