Test field A4: Environmental and traffic data

Description

The environmental data provided here record the state of the atmosphere (precipitation, relative humidity, wind, etc.) and the road surface (road surface temperature, water film thickness, etc.) on test field A4 of the BASt. The selection of sensors primarily refers to the application in road operation (especially smoothness prediction for winter service) and for traffic control. Further use would be conceivable in combination with fleet data for friction value prediction in connection with automated driving. The test field is used for the direct evaluation of the sensors or by comparing measurement data with each other for the validation of laboratory test methods. Where laboratory tests are not yet possible, comparisons to statements of measurement uncertainties are used. Statements on the accuracy of the sensors on the test field and the status of the test methods used can be found in the report ‘New sensors for road weather stations’. Report: New sensors for road weather stations (OPUS)
The data is provided as minute values in two formats:
  • Untreated data (raw data) as provided by sensor manufacturers. They can be used to derive the measurement uncertainties of the sensors. In addition, traffic data in the form of traffic volume and speed separated by lane and class (cars and trucks) are provided for analysis. The data is updated daily.
  • Data from five compiled street weather stations (SWS) with plausible measured values. The plausibility check is carried out according to the rules from the FGSV note paper H PEB SWIS. The data from these stations will be made available to the DWD for predictions as part of the road condition and weather information system SWIS Info. The predictions can be viewed there with the appropriate access authorization. The data is updated daily.

Note: The sensors are regularly serviced by the manufacturers. There is no permanent control by the BASt. High measurement tolerances or sensor errors can only be assessed by means of the plausibility checks shown or by means of photos. No sensor currently serves as a reference for a parameter. In addition to manufacturing-related measurement tolerances, differences between the measured values for a parameter may also be due to the design or location of a sensor in the test field. The latter relates only to the parameters of the roadway. Here, the position of the sensor in the cross-section of the road must be taken into account. In the longitudinal direction of a cross-section, no significant differences could be found in the short test field section. No different influences are seen in the atmospheric parameters. With the exception of precipitation sensors, they measure at a height of about 4 meters above the ground.
