1. A processor-implemented method for vehicle convergence analysis based on a plurality of sparse location data, the method comprising: obtaining, by a processor, a plurality of vehicle location data, wherein the received plurality of vehicle data includes a location associated with a vehicle, a license plate text associated with the vehicle, and a date and time of a sighting of the vehicle; receiving a plurality of input data, wherein the plurality of input data includes at least two license plates that are associated with at least two vehicles, wherein each license plate is associated with a different vehicle, an indicated time span on which to run an analysis on the obtained plurality of vehicle location data, and an indicated time difference between an actual route and an estimated route; calculating, for each vehicle associated with the at least two license plates, a street network route based on each sequential piece of timed data and each piece of location data included in the obtained plurality of vehicle data and the received plurality of input data; identifying a plurality of overlapping routes between the at least two vehicles associated with the at least two license plates based on the calculated street network route wherein the plurality of overlapping routes correspond to at least one portion of the street network route of a first vehicle overlapping with at least one portion of the street network route of a second vehicle, the first and second vehicles corresponding to the at least two vehicles; calculating, for at least one overlapping route in the plurality of overlapping routes, an expected time period for the first and second vehicles to travel through the at least one overlapping route; calculating, for the at least one overlapping route, an actual travel time period for the first and second vehicles to travel through the at least one overlapping route; identifying the at least one overlapping route for displaying based on the actual travel time period exceeding the expected time period by more than a threshold value; and displaying the identified plurality of overlapping routes, including the at least one overlapping route, between the at least two vehicles as a meeting area.
