RoadRunner: improving the precision of road network inference from GPS trajectories
Hi there,
I am currently doing some research on map construction methods, and have chose to incorporate the RoadRunner algorithm.
I am stumbling however on the config file. In the paper, a case is shown where only a single entrance is given, from which the rest of the map is explored. I am currently trying to achieve the same thing on the athens_small map. However, every entrance point is explored only for a very small amount, even if I tune the parameters of the config file all the way down. Is this unexpected behaviour or is the algorithm only capable of producing a complete result if a lot of entrance points are provided?
Below is an image of what I am getting with the most relaxed parameters.
