Mishandling of cycleway:left:oneway=-1? #119

Closed graue closed 1 year ago

graue commented 1 year ago

We're avoiding going northbound on Scott between Oak and Fell, specifically the part at the very north end of the block where motor vehicles are not allowed to travel south:

It's clearly avoiding this little part:

Southbound works:

The way at the very north end is tagged

oneway=yes
oneway:bicycle=no
cycleway:right=lane
cycleway:left=lane
cycleway:left:oneway=-1

These tags seem correct. The bug might be that we treat cycleway:left:oneway=-1 and cycleway:right:oneway=-1 as equivalent to oneway:bicycle=-1. (See isBackwardOneway().) The latter means that bicycles can only travel opposite the OSM way direction on the entire road.

In a possibly related issue, going contraflow on Battery Street is being avoided: https://bikehopper.org/route/Montgomery%20Street%20Station%2C%20One%20Post%20Plaza%2C%2091405@-122.40105019019208,37.7895225/to/Calhoun%20Terrace%2C%2094113@-122.4035842,37.8011083
