ADEC Technologies delivers 60 of its top-of-the-line TDC3-8 vehicle-classification detectors to ASFiNAG for installation at IGL sites. IGL refers to an Austrian law that codifies air pollution limits on highways.
Each IGL measurement point comprises a gantry with detectors and a VMS indicating the current speed limit. The limit is reduced when the emissions calculated from the actual air quality, as well as the speed and number of vehicles in each class, exceed a certain threshold. Conversely, the speed limits are raised when the opposite occurs.
TDC3-8 devices classify vehicles into 8+1 vehicle classes according to TLS. Classification accuracy meets or exceeds TLS A1 level for all but car with trailer (79.3%), trucks with trailer (A2) and busses (A2). Vehicle speed measurement is also well above the TLS-required accuracy levels, at 2.48km/h (for vehicles with speeds ≤ 100km/h) and 2.11% respectively (for vehicle with speeds > 100km/h).
Markus Güntensperger, product manager at ADEC Technologies says: "Our engineers have done an outstanding job in bringing out this next version of the three-technology traffic detectors.
"It’s a significant step forward and we are excited to be able to offer such superior detection quality."
The tests were commissioned by an independent ITS provider in Austria on an ASFiNAG testing site. The detailed test report will be published on ADEC Technologies’ website.
