1. A method of detecting overspeeding for a vehicle of a fleet, the method comprising:
obtaining historical trajectory data of the fleet of each geographical area of a plurality of geographical areas from an electronic database;
determining, by a microprocessor of a server, a distribution of speed of the historical trajectory data for each geographical area;
de-skewing the distribution of speed based on an inverse proportional relation to a speed associated with each of a plurality of datapoints of the distribution;
based on the distribution of speed, determining, by a microprocessor of an electronic device-associated with the vehicle, that a current speed of the vehicle is above a threshold speed corresponding to a pre-determined percentile of the distribution of speed in a current geographical area in which the current speed is recorded, which current geographical area corresponds to at least one of said each geographical area,
transmitting, for display to a driver of the vehicle, an alert about current unsafe speeding,
wherein the server and the electronic database are communication coupled to each other via a communication interface,
obtaining includes communicating, by the server an electronic request to the electronic database for the historical trajectory data, and communicating the historical trajectory data from the electronic database to the server via the communication interface.
