Figure 11 illustrates the interpolation in action where the black colored dots are imprecise GPS points and colored dots are points snapped on to the street or bike lane. A clear limitation is that points too far away from the bike-lane (outside the chosen buffer) will not have a bike-lane assigned to it, and therefore they won't have a new point on the bike-lane. In the intersections, we can have competing candidate's bike-lanes and therefore, points may be assigned incorrectly.
