Traffic intensities statistics: use of road sensors

Use of road sensors to traffic intensity information

On the basis of road sensor data for Dutch motorways, monthly traffic intensities are calculated for each road per COROP region. The project results in official statistics.

Project Objective:

For the production of statistics

Project Outcomes:

The intended outcomes were official traffic intensities statistics, which were realized in July 2015. See http://www.cbs.nl/nlNL/menu/themas/verkeer-vervoer/publicaties/artikelen/archief/2015/a13-drukste-rijksweg.htm

Project Details
Project Details
Frequency Comments: There are about 60,000 road sensors on Dutch roads, of which about 20,000 are linked to motorways. For each sensor, the number of passing vehicles per minute and the average speed for different categories of vehicle length are measured.
Data Quality
Data Quality
Quality Aspects Evaluated: Completeness, Usability, Time Factors, Validity, Accuracy, including selectivity
Validation Comments: All data per minute from functioning road sensors on major Dutch motorways is collected. These data is immediately filtered to remove any distortions. Once an estimate of the intensity per minute has been made, daily aggregates of the data series are prod
Quality Framework Comments: No existing quality framework has been explicitly used, although all relevant professional quality considerations were respected. See: http://www.cbs.nl/NR/rdonlyres/25CE3592A756-42B7-BABFC3E4C4E9375B/0/a13busiestnationalmotorwayinthenetherlands.pdf
Data Quality Concerns Comments: Not all data obtained are correct, but dysfunctional sensors are detected, and no traffic loop is indispensable.
Quality Assessment Comments: All aspects are relevant, but require a substantial effort.
