1. A vehicle traffic management system comprising:

  • an input/output subsystem to receive a plurality of route search requests from a plurality of client devices; and

    a central processing unit to search a route data base for a suitable match for the plurality of route search requests yielding a plurality of routes, wherein;

    the input/output sub-system is operative to receive data related to traffic levels along the plurality of routes;

    the central processing unit is operative to;

    calculate a score for each one route of the plurality of routes a given vehicle can take from an origin to a destination, the score representing an estimated journey time along the one route based on extrapolated vehicle traffic levels along the one route, the extrapolated vehicle traffic levels determined using at least (a) the data related to traffic levels along the plurality of routes and (b) statistics of the plurality of client devices, wherein the score for each route of the plurality of routes is periodically recalculated and a gap until the next recalculation is shortened when a most recent score has changed by more than a predetermined percentage;

    select N quickest routes from the plurality of routes based on the score of each one route of the plurality of routes; and

    allocate the N quickest routes among the plurality of client devices, wherein;

    only one quickest route of the N quickest routes is allocated to each one of the plurality of client devices;

    a first client device of the plurality of client devices is allocated a first quickest route from the N quickest routes, the first quickest route having a first score; and

    a second client device of the plurality of client devices is allocated a second quickest route from the N quickest routes, the second quickest route having a second score which is different to the first score; and

    the input/output sub-system is further operative to send to each one client device of the plurality of client devices data about the one quickest route allocated to the one client device.
