1. A system for automatically navigating a vehicle, said system comprising:
- a data storage for storing one or more data sets physically describing one or more areas;
a first electronic interface for receiving data relating to the one or more areas from external data sources;
a second electronic interface for receiving parameters relating to motion of the vehicle from physical sensors;
a navigation processor comprising processing circuitry adapted to determine an initial optimal route for traversing the vehicle from a given point in the one or more areas to another point in the one or more areas by computationally resolving a constrained minimization problem, wherein;
(iii) constraints of the constrained minimization problem are physical capabilities and limits of the vehicle and a physical space within the one or more areas appropriate for traversing the vehicle; and
(iv) an optimization parameter of the constrained minimization problem is a cost function, which cost function comprises a weighted aggregation of cost values representing each of;
safety of the passengers, safety of other people, safety of the vehicle and other property, obedience to traffic regulations, minimizing travel time and minimizing cost.
