1. A method for controlling vehicular congestion at intersections, the method comprising:
detecting, by one or more processors, a group of two or more vehicles stopped at an intersection regulated by a traffic light, including determining that a head vehicle in the group is within a first distance from the intersection, and that each subsequent vehicle in the group is within a second distance from the head vehicle, wherein for each of the vehicles in the group, movement through the intersection in response to a change in a state of the traffic light is affected by movement of at least one other vehicle in the group;
determining, by the one or more processors, a time when the state of the traffic light changes to allow the group of vehicles to start moving through the intersection;
determining, by the one or more processors, one or more acceleration parameters for a certain vehicle in the group in view of potential and/or actual movement of the other vehicles in the group through the intersection;
providing, by the one or more processors, guidance to a device operated by a driver of the certain vehicle regarding the determined one or more acceleration parameters, in accordance with the determined time.
