How can I extract GPS traces from Open Street Map as individual trajectories of a particular area (Bounding Box). Right now when I get the gpx (GPS trace file) file of a particular area selected by Bounding Box I get a set of points, but they are not organised based on which points belong to which particular trajectory. The reason I am doing this is to collect all the complete trajectories and not some set of GPS points of a particular area.

Please feel free comment if the question is not clear.....

Thanks in advance.....

This is a feature not a bug.

Traces can be uploaded to OSM with various degrees of privacy. The raw trace download is of a point cloud of all traces within a given area. Public traces which are the ones which will enable you to view the trajectory are associated with individuals have unique identifiers (this is a recent one of mine).

I don't believe that there is an API call which allows downloading all such traces in an area. Rather traces can be retrieved by id or by user, or by keyword for a given user.

These limitations are at least partly influenced by the need to offer a basic level of privacy protection to people submitting traces, whilst making them useful for mapping.
