Design of a new electronic tagging device for cars using the new toll roads in Australia. As part of the design advice to Transurban, Denton Corker Marshall has designed a new electronic tag to be placed on car windscreens to allow them to be electronically tolled when using the company’s toll roads in Australia. The existing tag was re-interpreted to take the shape of a black tube. This form allows it to fit discretely along the top edge of the car windscreen.
