On-Demand Travel Through a Transportation Network

On-demand travel through a transportation network is achieved by receiving, via a communication device, a request for a trip through the network using a vehicle. The request includes criteria for the trip and a goal for the trip, the criteria identifying a target duration of the trip, a starting location of the trip, and an ending location of the trip, and the goal is other than reaching the ending location from the starting location using a shortest time or a shortest distance. Based on the request; a route for the trip between the starting and ending locations is determined that has a predicted duration no greater than the target duration. The route includes a waypoint between the starting and ending locations determined based on the goal of the trip, and the route is transmitted, via the communication device, to a source of the request for traveling the route.
