1. A system for predicting vehicle collision comprising:

  • a system vehicle including a velocity sensor, and a location sensor for detecting the velocity and location of the system vehicle;

    at least one pedestrian detection system, the at least one pedestrian detection system having a base and a mast extending from the base, and a plurality of sensors mounted on the mast, the plurality of sensors detecting objects, to include pedestrians, and wherein the sensors include a GPS antenna, a thermal imaging camera and a high-resolution camera, an alert mechanism, a radio with an integrated directional antenna, and a short range communication antenna, wherein the at least one pedestrian detection system processes the images captured by the camera with GPS information from the GPS antenna to map the location of the objects;

    a path predicting circuit in communication with the system vehicle and the pedestrian detection system, wherein the path predicting circuit predicts the path of the system vehicle based upon the velocity or location sensor and predicts the path of objects detected within the predetermined range of the pedestrian detection system;

    a path collision circuit in communication with the path predicting circuit, wherein the predicted paths of the system vehicle and the object are mapped onto the path collision circuit so as to determine if the system vehicle and the object may collide, the short range communication antenna communicating with the system vehicle, wherein the short range communication antenna transmits a warning to the system vehicle when a collision is predicted, and wherein pedestrian detection system actuates the alert mechanism so as to warn pedestrians of a potential collision.
