1. A method of monitoring the speed of an automotive vehicle comprising:

  • operating a vehicle navigation system to determine a location of the vehicle relative to an approaching road segment lying ahead of the vehicle;

    accessing a first speed profile of the approaching segment, the first speed profile saved in a database and generated by analyzing a statistical distribution of historical speed data collected from probe vehicles that have previously travelled over the approaching segment;

    identifying a baseline road segment over which the vehicle has previously travelled;

    accessing a second speed profile of the baseline segment, the second speed profile saved in the database and generated by analyzing a statistical distribution of historical speed data collected from probe vehicles that have previously travelled over the baseline segment;

    comparing a past speed of the vehicle over the baseline segment with the second speed profile to determine a speed differential; and

    applying the speed differential to the first speed profile to establish a target vehicle speed over the approaching segment;

    assessing whether the vehicle is likely to exceed the target speed over the approaching segment based, at least in part, on a current vehicle speed; and

    activating a vehicle system to a) notify a vehicle driver of results of the assessment, and/or b) reduce vehicle speed.
