Realtime socially-derived and shared time-of-arrival estimation to a destination

A method, comprising acts of:

• computing estimated time-of-arrival (ETA) information of users travelling from respective identified locations to a shared destination as associated with navigation of the users to the shared destination along specific routes;
• sharing current locations of the users, associated ETA information, and routes, among the users for viewing by each of the users;
• enabling interactive communications between the users via a navigation system;
• updating the ETA information of the users in realtime during travel of the users to the shared destination;
• and
• utilizing a microprocessor that executes instructions stored in memory to perform at least one of the acts.

One or more memory devices storing processing instructions that, when executed, cause one or more processing devices to perform a method, comprising:

• computing estimated time-of-arrival (ETA) information of users travelling from respective identified locations to a destination as associated with navigation of the users to the shared destination along specific routes;
• sharing current locations of the users, associated ETA information, and routes, among the users for viewing by each of the users;
• enabling interactive communications between the users via the navigation system;
• and
• updating the ETA information of the users in realtime during travel of the users to the shared destination.
