Every morning, empty seats pass people who need to travel along nearly the same corridor. The useful fact is not that somebody can be dispatched right now; it is that a verified neighbor reliably goes from X to Y on Tuesdays and Thursdays and may be willing to cooperate. That durable overlap is normally invisible unless the two people already know one another.
The cost of that invisibility is not evenly distributed. The Bureau of Transportation Statistics reports that Americans with travel-limiting disabilities make fewer daily trips, are less likely to have a vehicle, and often compensate by asking others for rides or limiting when they travel. A missed route match can therefore become a missed shift, appointment, class, or relationship.
Routes is a mobile social network for verified users. It records motion data automatically and, after the same trip occurs several times, asks whether it is a regular route. The user can register availability or need as “I am traveling from X to Y”, letting the service compare persistent routes without announcing anyone’s live location.
