The Stockholm Traffic Administration Office has been measuring the flows of how cars, cyclists and pedestrians move through Stockholm for several years as part of the city’s accessibility strategy. The measurements provide a basis for improvements such as where sidewalks need to be broadened to reduce congestion and which routes should be equipped with heat pads on the sidewalks.
The technology currently used is a simple infrared beam of light. But the problem with this technology is that it is less accurate when the traffic is heavy and the sidewalk is crowded with pedestrians.
The new advanced measurement stations use a 3D technology capable of counting individual pedestrians even when the sidewalk is crowded with many people. The technology can also distinguish between those who pass by, such as cyclists, dogs and ordinary pedestrians. The cameras that are used take 3D images which are then analyzed by a computer program. But the pictures are never sent on from the cameras and are not stored anywhere.
The technology in the new measurement stations will now be evaluated over a two-year period. The new advanced measurement stations are being tested first within the scope of Urban ICT Arena, along Kistagången. Additional measurement stations are in progress at six separate locations in Stockholm.
