> Transverse ridges are better for bikes > Longitudinal ridges are better for pushchairs
Longitudinal ridges oppose side-slip, which is more dangerous to those on two wheels. When climbing a hill, transverse ridges give better traction; a bike is likely to have some momentum to carry it through the market slabs, whereas a push-chair is likely to stop more quickly without power.
Or at least that was the rationale I deduced upon finding the slabs at the Nuffield Gym (nee Greens) end of the Coldhams Lane railway bridge, where traffic has either just turned left or sharp right when it meets the ribbed paving.
It is not obvious to me that either direction of tile is obviously better or worse for two than four wheels in all, or even most, situations.
