Heterogeneous impacts of protected bike lanes on bikeshare behavior across demographic groups in New York - npj Sustainable Mobility and Transport

Decisions regarding the installation of bicycle infrastructure require evidence of whether and to what extent different bicycle-lane types increase ridership. However, associations between bicycle infrastructure and ridership have primarily been studied in the context of individual lanes and corridors, or when analyzed at the scale of entire cities, generalized across different bike-lane types. Drawing upon 72 million bikeshare trips from Citi Bike in New York, we demonstrate that there is an approximately 18% increase in bikeshare trips at adjacent stations in the 12 months following the installation of protected bike lanes and a 14% increase associated with painted bike lanes and ‘sharrows.’ However, using propensity score matching and difference-in-differences analysis to compare bike stations with similar surrounding social and built-environment characteristics, we find a causal effect on bikeshare ridership only after the installation of protected bike lanes, with an average monthly increase of 379 rides per station (p < 0.001).

    after “all of the above” they specify the 30kph as “if it’s only a raised border”

    Yes, that’s why I asked if they really meant “all of the above” - I rather suspect they were just referring to the other measures that do make sense for both protected and unprotected cycle paths (only bicyclists allowed, distinctive paint schemes etc).

    a 2-3in stepped concrete block and keeping the cycling lane raised

    pretty sure this is what is meant by protected cycle lane - some kind of kerb between the cycle lane and the motor vehicle lane. There are many cycle lanes like this in Europe and they are unquestionably way safer. FYI you don’t need to have the cycle path raised to the same height as the kerb - many do not do that, and just have a line of raised kerb stones on the traffic side of the bike lane.
