RBPIS / traffic system


Road-block press induction system is a new way to control traffic lights by calculating traffic frecuncy. By decreasing the frequency and time of traffic lights shining, this system reduces the amount of electricity city uses. It also helps promote traffic efficiency.
This system set induction pads beneath road-blocks, which collect vehicle movement. The electric counter is linked to inductions to calculate number of passing cars in a fixed time. Every time vehicle presses the road-block,the electric counter will calculate via induction. How long lights remain red or green depending on both crossings’frequency.
