More information about the visibility sensors can be found here.Langford J, Koppel S (2006) Epidemiology of older driver crashes – identifying older driver risk factors and exposure patterns. This model can be connected via an interface to the OPUS GMA module data logger.
The second visibility sensor has a measuring range of up to 16 km (10 miles), while 3,000 meters (about 2 miles) is usually sufficient for traffic control purposes.
Many traffic control systems on the German Autobahn are equipped with these Lufft sensors. Both available models work with the forward-scatter measurement principle. The digital UMB protocol allows the sensor to connect to a data logger. The VS20-UMB Visibility Sensor is available in two versions offering precise measurement of visibility of up to 2,000 and 3,000 meters (between 1-2 miles), respectively. Many such systems are able to switch on/off automatically because they are connected to visibility sensors on the roadways. Heed any fog warnings you might see on motorways and limit your speed accordingly. Integration of Lufft Visibility Sensor VS20-UMB Road-control installation – German Autobahn A8 near Stuttgart Fog lights may be switched in fog, rain or snow even if you can see more than 150 feet. This is the only situation when you should be using your high beams because they would blind the oncoming traffic if visibility were better.
If fog has cut down your ability to see more than 50 meters (150 feet) ahead of you, you should be driving no faster than 30 mph. That’s why it’s important to adjust your speed to the actual road conditions. Your risk of slipping and sliding on the road also increases when there’s fog or snow. There can be a traffic jam or slower vehicle just around the next curve in the road. Another important rule is: Adjust your speed. You also need to make sure that your headlights are not dirty or covered by leaves and snow.

When visibility is limited, you should turn on your low beams so that other drivers can see you coming more quickly. “See and be seen” – that should be your motto.
Accidents often result when car drivers are unable to recognize the vehicles ahead of them quickly enough to respond in time by braking.Īdopting just a few simple habits can reduce the risk of a traffic accident significantly.
