Even though some cities have dedicated bicycle infrastructure, it’s of no use if you don’t know where it is. While Google Maps is excellent for car navigation (and the dominant market leader), it often has patchy cycle infrastructure coverage and tends to generate cycle routes on busy roads. The best dataset of cycle infrastructure worldwide (and in Sydney) is OpenStreetMap. OpenStreetMap is like Wikipedia but a map; anybody can edit it, and the sheer number of contributors ensures accurate data. Many cyclists (including myself) contribute to this dataset.
I undertook a four-year project to document the construction over 6 focus trips at various stages of development, as well as after the opening of the Randwick segment.
