Abstract: Embodiments provide techniques, including systems and methods, for locating and navigating to the location of a requestor based on proximity between a requestor device and a provider device. For example, embodiments display proximity indicators to allow a provider to quickly, easily, and safely locate a requestor upon arrival near a request location. Further, in some embodiments, graphics associated with a proximity vector may be presented on a provider communication device to clearly display the navigation directions to the provider so that the provider may easily find their matched requestor without requiring additional communication between the provider and the requestor. Additionally, embodiments provide efficient navigation to riders by limiting display of proximity indicators for navigation until the provider is within a threshold distance to the request location to conserve system resources and communication between an on-demand matching system and the provider computing device.

Abstract: Personalizing travel route planning based on past actual user travel behavior and reasons that the user deviated from planned routings. The route planning algorithm is revised based on analysis of user input related to a deviation from a planned routing. If a new trip in the planning stage entails considerations similar to those that caused the user's deviation on a previous trip, then the revised route planning algorithm can take these considerations into account when planning the route for the new trip. Changes in route planning may apply when the user: (i) plans to make a trip similar to a previous trip when the deviation occurred; (ii) plans to make a different trip, but the trip entails considerations that lead to the deviation on the prior trip; (iii) is using the same vehicle as for the previous trip with the deviation; and/or (iv) is using a different vehicle.

Abstract: The present invention is a computer-implemented system for providing guidance information to aid a user in traveling along an off-road route. This system assumes that the route has already been determined. Also, it is assumed that the user's position and orientation can be determined, for example using existing techniques such as the global positioning system (GPS). The present invention uses a Look-Ahead-Point Finder (100) to find a point, which we refer to as a look-ahead point, located on the route ahead of the user's current location. A Guidance Message Constructor (102) and a Guidance Presenter (106) are used to present the user with guidance information directing him towards the look-ahead point. If the user is already headed towards the look-ahead point, then a Turn Analyzer (108) is used to search the route in order to find the next turn location.

Abstract: The described method and system provide for treatment of certain areas as neutral zones during GPS navigation to avoid unnecessary off-route notifications and route recalculation. A GPS unit determines whether the user has entered a geographic region designated as a neutral zone, and does not provide the user with off-route notifications while the user is within the neutral zone. Not providing off-route notifications may be implemented by the GPS device by considering the user to be within the calculated route while the user is within a neutral zone, or by disabling off-route notifications (and route recalculation) while the user is within the neutral zone. The neutral zone may be defined by a set of GPS coordinates. The neutral zone may further be polygonal, and the size of the neutral zone may be based on the accuracy of the GPS device.

Abstract: Techniques are described for monitoring whether a user is following directions to a destination during electronic navigation to the destination provided by an electronic navigation device. When the electronic navigation device determines that the user is not following directions to the destination (e.g., the user has missed several turns suggested by the electronic navigation device), the electronic navigation device determines that the user appears to be avoiding the route (or a primary component thereof) to the destination. In response to a determination that the user appears to be avoiding the route (or a primary component thereof) to the destination, the electronic navigation device may automatically, without human intervention, perform an operation directed to using an alternative route (or alternative primary component) to the destination despite the current route remaining preferred according to current routing settings.

Abstract: Alternative routes to an optimal route may be determined and presented to a user via a computing device. Alternative routes are selected from candidate routes that meet admissibility criteria. In an implementation, admissibility of a candidate route (in order for it to be considered an alternative route) may be determined based on three criteria: “limited sharing”, “local optimality”, and “stretch” such as “uniformly bounded stretch”. Limited sharing refers to the amount of difference between the alternative route and the optimal route, local optimality refers to lack of unnecessary detours, and uniformly bounded stretch refers to a length of the shortest path to travel between two points on the alternative route.
