Wouldn’t you find it reassuring to have just one traffic light system capable of controlling almost every road traffic situation needing a mobile traffic light?
A traffic-light system consisting of two or several MPB 4400 signal heads can be used to control one-way traffic through to crossroads, ideally with vehicle actuation. The interesting thing about our system is that all traffic lights are 100 % identical and can be combined by the user in any way time and again, depending on the specific traffic situation.
The simple addition of an identical third signal head already lets you control a T-junction. And with just four individual signal heads, i. e. two complete trafficlight systems, you can deal with crossroads traffic or a pedestrian crossing. In other words, with two available MPB 4400 traffic light systems, in practice you can control alternating one-way traffic in two different places on Mondays, a T-junction on Tuesdays, a crossroads on Wednesdays, a pedestrian crossing on Thursdays and on Fridays, local public traffic signalling with special signal patterns for local buses.
Applications:
The MPB 4400 roadworks traffic-light system brings together decades of experience in both the production and daily practical use of mobile traffic light systems, combining them with innovative ideas.
The MPB 4400 is adjusted with the convenient handheld terminal for really easy operation. The traffic-light system can be adjusted in just a few steps without any special previous knowledge. Once the handheld terminal has been switched on, it polls all relevant parameters in a dialogue. The following explanation shows e.g. how to adjust a vehicle-actuated one-way traffic control:
The signal timetable can also be entered in the handheld terminal in the peace and quiet of the office, right away from the actual traffic light. Once the traffic lights have been set up at the roadwork site, the fitter simply places the programming device in the signal head and transfers the already compiled data to the traffic lights – that‘s all!
By the way, all data can be read back into the handheld terminal and changed if necessary before being transmitted to the traffic lights again, without having to switch any part of the system off.
