Hi all, I sent this to the talk-us list, but responses have been few. I'm hoping a bit more dialogue could happen on the talk list.
In Portland, Oregon, four interns at the local transit agency (TriMet - http://en.wikipedia.org/wiki/TriMet) are attempting to improve and update OSM so as to make it routable. TriMet will be switching to OpenTripPlanner ( http://opentripplanner.org/, http://wiki.openstreetmap.org/wiki/OpenTripPlanner) in a few months, and will draw its base map from OSM. We are trying to make sure streets have correct geometry, directionality and names; intersections have turn restrictions; bike routes are properly tagged; and trails and pedestrian routes are up-to-date, accurate and tagged. The trip planner is multi-modal, meaning it incorporates bicycling, walking and transit, and combinations thereof. Anyways, the point is... We have been tagging multi-use paths that are also considered bike routes as highway=path and bicycle=designated. Another user prefers highway=cycleway. What criteria do other mappers use to distinguish between a cycleway and multi-use path? Terms: Cycleway: http://wiki.openstreetmap.org/wiki/Tag:highway%3Dcycleway "The highway=cycleway indicates that the used way is mainly or exclusively for bicycles. Some consider it better to use highway=path if use is not restricted to cyclists." Path: http://wiki.openstreetmap.org/wiki/Tag:highway%3Dpath "This tag is used for paths for which all and any of highway=footway, highway=cycleway, and highway=bridleway would be inappropriate or inadequate (or simply not sufficient), but which are nonetheless usable for travel or navigation. They might be not intended for any particular use, or intended for several different uses. Intended uses can be indicated with the access=designated keys. It is also used for hiking trails." Some examples of multi-use paths that have switched between highway=cycleway and highway=path: Eastbank Esplanade http://www.portlandonline.com/parks/finder/index.cfm?PropertyID=105&action=ViewPark Morrison Bridge Multi-use Path http://bikeportland.org/2011/06/10/morrison-bridge-path-to-close-for-construction-project-54559 Hawthorne Bridge, with both pedestrian and bicycle markings http://bikeportland.org/2005/11/21/hawthorne-bridge-gets-new-markings-673. Traffic stats: In 2008, the breakdown for peak-hour (4-6 pm) usage of these trails shows that cyclists usually dominate, but pedestrians make up 15% to 50% of the traffic. http://www.portlandonline.com/transportation/index.cfm?c=34778&a=292746 Thanks! -- PJ Houser Trimet GIS intern username: PJ Houser
