[OSRM-talk] getting into Oxford Street

Hi Alan,

  Hmm, the best way to figure this out is going to be to use the OSRM debug map:

    http://map.project-osrm.org/debug/#15.79/51.5140/-0.1515 <http://map.project-osrm.org/debug/#15.79/51.5140/-0.1515>

  This shows roads that are routable (colored), and roads that are isolated from the rest of the network (highlighted in pink).

  I can see that there are some missing roads as well - this means that OSRM has removed these from the routing network,
  usually because of access restrictions (i.e. no cars allowed).

  This node:

    http://www.openstreetmap.org/node/2198870645 <http://www.openstreetmap.org/node/2198870645>

  indicates that you can't continue straight along Oxford Street there - you're only allowed to turn left.  I don't know if this is real or not.
  There are also no turns allowed from Regent St onto Oxford St here - this is preventing access to the section of Oxford St just to the
  west here.

  The OSRM demo server updates with new data every couple of days.  If you make changes to OSM, you can check:

    http://router.project-osrm.org/status <http://router.project-osrm.org/status>

  to see what data the OSRM demo server is using, and whether any changes you've made have taken effect yet.
