Total lenght of bike lanes in the city of Patras.

From wikipedia :

Segregated cycle facilities (a.k.a. bike lanes) are roads, tracks, paths or marked lanes designated for use by cyclists from which motorised traffic is generally excluded. The names and definitions of the various cycle facility types vary from country to country, but besides local naming conventions, one of the main subdivisions is whether the facility is physically separated from other (especially motor vehicle) traffic, or whether the segregation is only due to markings.
