According to Swedish company Triplesign, its new range of variable message signs (VMS), developed for lane closure operations has a number of benefits over traditional LED VMS. Visually, the sign is like a normal static traffic sign, but appearances can be deceptive. There are actually several signs built into each unit, one for each traffic lane on a multi-lane road. Each lane can be independently operated by the traffic management system.
