Claim 18:
19. An autonomous vehicle (AV) comprising a computer-readable storage medium that, when executed by a processor of the AV, causes the AV to perform acts comprising:
obtaining an origin location of the AV and a destination location of the AV, where the AV is to travel over roadways from the origin location to the destination location, and further where at least one of the origin location or the destination location is within a city;
obtaining a first value for a spatiotemporal factor at a first location within the city;
computing a second value for the spatiotemporal factor at a second location within the city, where the second location is along a roadway within a candidate route from amongst several candidate routes between the origin location and the destination location, where the second value for the spatiotemporal factor is computed based upon:
the first value for the spatiotemporal factor at the first location; and
a distance between the first location and the second location;

computing a likelihood value that is indicative of a likelihood of a predefined event occurring at the second location at a time that the AV is estimated to be at the second location when travelling the candidate route between the origin location and the destination location, where the likelihood value is computed based upon the second value for the spatiotemporal factor at the second location;
selecting the candidate route from amongst the several candidate routes based upon the likelihood value; and
controlling at least one of a propulsion system, a braking system, or a steering system of the AV to cause the AV to travel over the candidate route between the origin location and the destination location.
