Hi, i am seeing interesting issues with 0.4.3 - I used to calculate routes with 0.3.8 and the route was always exactly returning the OSM geometry/nodes.
No i am seeing what seems to be rounding/nearest street match errors. A small image i created with QGis with a OSM WMS below created routes. You see approx. 100 routes above each other. Every "house" starts it own route. You can now see that the nearest road is not matched exactly but rather "nearly". I havent seen something like this with osrm 0.3.8. http://silicon-verl.de/home/flo/tmp/example-geometry-osrm-0.4.3.jpg The orange lines with the arrows on there are LINESTRING from the route_geometry which i put into a postgis. The smaller blue lines are the connection between the starting point of the route and the first point returned in the route_geometry produced by ST_MakeLine(ST_StartPoint(geometry),a.position) Another thing is that i can not explain the North<->South route on the left side which misses the road completely until the next junction.
