As I was working on improving the visualization of route relations I had to improve the data part of the public transport. now one can get the nearest way to a bus stop and all stops a way is serving. stop can be identified as left or right side according to the direction of the way it is serving. these features of the data will help in making the edges in route relation which will be my next task. By using these it has also improved the sorting of pt_route members including the stop which was not working properly before(was creating the duplication of stops when it was passing through a two-way road).
