Somewhere in the centre of Bury on a gloomy day. The first image is the standard deviation of 20 seconds of activity in the street. The ‘whiter’ parts of the images are the people moving up and down the street. The map in the middle of the image is clearly directing people to both sides of the street.
The second image is the maximum intensity of the same 20 seconds. As a result the whole image is brighter. The whiter images on the road are also the people walking but I think the vertical lines that go from above the map across the image to the right ‘might’ be sunshine reflecting off the camera lense (either that or aliens were landing in Bury - and given the weather today that seems a bit more likely).
