1. A method of enhancing road safety for vehicles traveling on a network of roads, the method comprising:
- receiving, at an interaction detector, a plurality of monitoring vectors from a plurality of vehicles travelling on the network of roads, the plurality of vehicles including at least a first vehicle and a second vehicle, the interaction detector being remote from the plurality of vehicles;
determining, from the plurality of monitoring vectors, whether there is an interaction between the first vehicle and the second vehicle, the interaction existing when the first vehicle is within a risk radius of the second vehicle, wherein;
the risk radius is a predetermined distance such that the first vehicle and the second vehicle have a risk of collision, andthe second vehicle is offset from, and not at, the center of a circle defined by the risk radius;
the interaction being determined without use of prior knowledge of a pre-planned route of either of the first vehicle and the second vehicle on the network of roads; and
alerting an occupant of at least one of the first vehicle and the second vehicle that the interaction on the network of roads has been determined.
