I know... The first subnetwork removal consider the oneway as bi-directional way. (But isFoward==false and isBackward==false, will be considered block.) Map<Integer, Integer> map = findSubnetworks();
like 37.78373608999855,-122.25065187925067 size: 34 It has a oneway connection to the main network. (The other connection has a barrier=gate.) So, they are not treated as the subnetwork at first. Then when try to find the oneway, the directional is considered. So this subnetwork are recognized. unvisitedDeadEnds = removeDeadEndUnvisitedNetworks(singleEncoder); *Best Regards,* *ZhiQiang ZHAO* On Thu, Jul 23, 2015 at 2:03 PM, John Zhao <[email protected]> wrote: > Interesting, > when I increase minOnewayNetworkSize from 20 to 50, the following two > disappeared. > subnetwork start from: 37.32611992939085,-121.9961998312816 size: 24 > subnetwork start from: 37.78373608999855,-122.25065187925067 size: 34 > > *Best Regards,* > *ZhiQiang ZHAO* > > On Thu, Jul 23, 2015 at 1:55 PM, John Zhao <[email protected]> wrote: > >> Hi, >> >> I tried car flag encoder with following parameter on San Francisco bay >> area data from mapzen. >> >> https://s3.amazonaws.com/metro-extracts.mapzen.com/san-francisco-bay_california.osm.pbf >> >> minNetworkSize=200 >> minOnewayNetworkSize=20 >> >> I printed all the remaining subnetworks. >> edges: 591932, nodes 437420, there were 3496 subnetworks. removed them => >> 13121 less nodes.
