A flawless and safe flow of traffic. The conversion of the traffic signs on the A20 contributes to this. Compass has replaced the old traffic signs on the A20 between Terbregseplein and Nieuwerkerk a/d IJssel. The entire process, from design to execution, is aimed at minimising inconvenience to road users and of course a successful system integration with flawlessly functioning links to other systems such as the rotation panels, detection loops and the interface station with the pump station (the Cortlandt Viaduct).
