The GPU TC Traffic Control System regulates and optimises the passages of motor vehicles on internal roads with limited space. The traffic control system is suitable for roads with one-way passage, e.g. garage entries and exits, passages to yards of residential houses, etc. The traffic control system can be also used as a solution for entries, exits, parking and movement of vehicles around industrial zones. The movement of vehicles in a monitored area is assessed by the GP DET vehicle detector. The autonomous control unit is fully programmable and thus it allows a wide spectrum of solutions to be adopted that comply exactly with customers' needs.
