Faster bike speeds or switching from walk to bike causes accessibility decreases #210

Closed mattwigway closed 8 years ago

mattwigway commented 8 years ago

Increasing the bike speed on the request can cause decreases in accessibility, clearly a bug:

Additionally, switching from walk to transit to bike to transit can cause decreases in accessibility. It may be that we're using a slower walk speed when walking a bike, or because we're taking into account turn costs even in the walk search when doing the bike search.

mattwigway commented 8 years ago

It may be that we're not properly combining the non-transit search with the transit search.

mattwigway commented 8 years ago

One bug: we were always calculating travel time based on walk distance in bike-to-transit mode, which obviously is nonsensical.

This should be fixed. I'll run another multipoint job to confirm.

mattwigway commented 8 years ago

Confirmed fixed.
