IRD's traffic products help make your roadways safer and more efficient. Products include Rubber Parking Curbs, Emergency Call Boxes (ECB), and radar speed signs. Rubber curbs are much lighter than concrete for easier handling and installation. They have applications in parking and slow-speed traffic routing. ECBs are used in toll system and HTMS applications.
