A view from the handlebars: all the the people seen cycling on cycleway 28 in the 2nd week of October 2025 (6 trips).

About 6Β½ riders/km, a decent showing, though a disappointing 22Β½% female participation (picked the wrong week, it’s usually 35%-ish).

Osaka’s showpiece streetscape Midosuji Boulevard has undergone major changes. In the build-up to hosting the 2025 World Expo, the city began experimenting with reallocating parts of the road space: widening sidewalks, limiting car traffic, and creating continuous protected infrastructure for bikes.🧡

What? When I’m in the opposite carriageway and there's plenty of room for everybody? The barriers are over what’s usually a taxi rank. It’s come to a pretty pass when Surrey’s roadworks are signed better than Outer London’s.

56 people waiting on red in the same section of video.

The same 4 riders and car appear in 2 completely different frames in the 0-200 count, and the signals show both red and green in a substantial section, because 2 video tracks have been overlaid. The green light track is fainter which makes it look like riders are jumppig the red.

Using the 0-200 count section in the Blackfriars pedestrian-cycleway crossing video, I can’t verify the claim that over ΒΎ of riders meeting a red light ride through it*, plus there are reporting anomalies as per the third picture.

PS over 300 go through on green.

From video analysis, the main cycle circuit inside Central Park has an elevation profile of 9.9 m/km and has about 8 male and 7 female riders per kilometre, similar to North Holland  with an elevation profile of 7.3 m/km (because of sand dunes) and 8 males, 8 females per km. 

A circuit in nearby city streets has an elevation profile of 3.6 m/km and from video has about 4 male and <1 female rider per kilometre, similar to southeast London with an elevation profile of 3 m/km and 3 males, <1 female per km.

By comparison  the Amsterdam area, with an elevation profile of 3 m/km supports 22 male and 22 female riders.

NYC cycle usage is very different inside and outside Central Park in Manhattan. It’s more like North Holland inside, and southeast London outside, despite inside being a bit hillier. Conclusion - make your cycle infrastructure like your parks. (see also Alt text)
