Determining network maps of transport networks
First Claim
1. A computer implemented method for determining a network map of a transport network, the method comprising:
- optimising for each of multiple sets of nodes a travel cost of trips with a start node and an end node in that set to select from each of the multiple sets one node as a hub, wherein the travel cost is based on whether the start node or end node is the hub;
optimising for each node a direct travel time between that node and a hub to select an optimised hub for that node;
determining a network map comprising the selected hubs connected to one another by a first transport mode and the remaining nodes connected to the respectively selected optimised hub by a second transport mode; and
repeating the optimisation steps to iteratively improve the network map wherein optimising the direct travel time further determines the multiple sets of transport nodes as nodes for which the same hub is selected.

Abstract
This disclosure relates a processor determining a network map of a transport network by. The processor optimises for each of multiple sets of nodes a travel cost of trips with a start node and an end node in that set. This way, the processor selects from each of the multiple sets one node as a hub. The travel cost is based on whether the start node or end node is the hub. The processor then optimises for each node a direct travel time between that node and a hub to select an optimised hub for that node. Finally, the processor determines a network map comprising the selected hubs connected by a first transport mode and the remaining nodes connected to the selected hub by a second transport mode. Passengers need to change less often at the hub because the hub is placed at the most popular destination or origin.

17. A computer system for determining a network map of a transport network, the computer system comprising:
-
a data store to store trip data comprising multiple trips; a processor to optimise for each of multiple sets of nodes a travel cost of the trips with a start node and an end node in that set to select from each of the multiple sets one node as a hub, wherein the travel cost is based on whether the start node or end node is the hub, to optimise for each node a direct travel time between that node and a hub to select an optimised hub for that node, to determine a network map comprising the selected hubs connected to one another by a first transport mode and the remaining nodes connected to the respectively selected optimised hub by a second transport mode, and to repeat the optimisation steps to iteratively improve the network map wherein optimising the direct travel time further determines the multiple sets of transport nodes as nodes for which the same hub is selected; and a data store to store the determined network map.
