Most modern jobhunting sites use a vague geographical locator to filter choices. In a large urban area, this may result in an overwhelming number of choices. The user should be able to filter these choices, not simply by distance or city, but by travel mode choices -- that is, is the job on a transit route? Pedestrian accessible? Online job listing sites should provide this service, but if not, it would be possible for a third party to overlay or make this calculation given the home and worksite addresses and access to transit routes and schedules. It might further be possible to advise the jobseeker what the costs of various modes would be.
