Any single route is defined in tables with an expected travel time (which does not always include taxi time on the grund), so for instance, it would be expected that a flight between two airports have a determined time consume. Further, you need to do checkin at a certain time before scheduled departure, and retrieval of luggage have an expected time, as well as a minimum time for connections. This way, the router will only need to know end-points of the route, but it need to be able to link up against departure times. Since each airline most likely have multiple services (with different ID number) between the same two airports, the data is more likely to be a table, best stored in a separate database, but with end-points linked to OSM-objects. The air-route relation is far from an ideal solution, only a work-around for not needing the routing engine to check multiple databases.

A pedestrian routing engine would use average walking speed as a base for travel speed instead of signed motor vehicle speed, and if intelligent enough allow to combine with public transportation.
