Correct cycle track definition and rendering #20

Closed trivisonno closed 1 year ago

trivisonno commented 1 year ago

Right now a cycle track is assumed to be two-directional, which is not necessarily always the case. Cycle tracks only mean, generally, that there is a physical/vertical separation element between the bicycle lane and the motor vehicle lanes.

See slides 12/13: https://raw.githubusercontent.com/OSM-DCT-Lyft/US/master/osmtrainingmaterialsfeatures/Bike%20Lanes.pdf and other OSM cycleway definitions. See also: https://www.fhwa.dot.gov/environment/bicycle_pedestrian/publications/separated_bikelane_pdg/page01.cfm#chapter1

Also need to update the length metric calculations, I think a cycle track is assumed bi-directional.

Check also what color blue the track renders--since tracks include physical separation, they should be dark blue.
