One of the latest innovations from road safety equipment company Nissen is NiNa (Nissen Navigation) Traffic and NiNa Guard, a combination of sophisticated sensor and a traffic counter which collects data on traffic density and speed.
Data collected by the system can then be used to warn oncoming motorists by displaying the traffic information and warning on variable message signs.
One of the latest innovations from road safety equipment company 3396 Nissen is NiNa (Nissen Navigation) Traffic and NiNa Guard, a combination of sophisticated sensor and a traffic counter which collects data on traffic density and speed.
Data collected by the system can then be used to warn oncoming motorists by displaying the traffic information and warning on variable message signs.
The system can be powered either by mains or solar panel and is mounted on the roadside, while the Nissen controller and sensor is housed in a weatherproof cabinet, and continuously monitors traffic flow. If the average speed of vehicles drops below a preset threshhold, the NiNa Guard detects this as a potential traffic jam, and using NiNa, which is based on GPRS, sends the data either to a control centre to warn motorists of a potential traffic jam, or it can be linked to the VMS system so a pre-determined signs can be displayed.
Recent trials in Germany on various locations are said to prove that the system is highly reliable and offers accurate information.
