If you find that some traffic flows in your wide-area matrix are not being assigned to the local matrices, this can be due to one of the following reasons:
1. Paths connecting the two locations have not been established, probably due to a missing connector between two traffic streams (or links). Note that this applies equally to local matrix flow allocation. You can use the “Show Downstreams” network diagram option to check that the connections you have ensure traffic reaches all the locations it should do. You can also use the flow allocation paths “filter” to systematically check that all the paths you think should exist have been created.
2. Paths have been disabled. N.B. bus and tram paths are, by default, “Disabled” and need to be enabled for them to carry traffic.
3. A wide-area matrix “Location” has been connected to a local matrix location which is not itself attached to an ENTRY traffic stream (or link). This is an absolute requirement – if the local location is not feeding an ENTRY traffic stream (or link) the flows will not be assigned from the wide-area matrix for that movement.
