[pgrouting-users] filtering the data used for shortest path calculations

You can effectively doing this by making the travel costs of Street X's segment very high. Doing this causes the algorithm to exclude the those segments from the solution since using them is costs.

Is it possible to filter out subpaths on the shortest path calculations? For example, if I wanted to use djikstra's algorithm to calculate the shortest path between point A and point B without using Street X?
