  • the violation information can be information confirming that a motor vehicle driver has violated the traffic light, identification information of the motor vehicle and location at which the traffic light was violated.
  • the violation information can be stored in a remote database (not shown).
  • the system 100 accessed through Internet (by relevant stakeholders), so as to be able to retrieve violation information.
  • the violation information can be transmitted through to the relevant stakeholders (i) at predetermined intervals of time (ii) when the number of stored unique identifiers of the RFID devices associated with the violation information reaches a predetermined volume (iii) when general cellular communication traffic is low, e.g. after midnight.
  • the traffic violation monitoring unit 106 is communicatively coupled to a A-GPS Server, which itself is communicatively coupled to a GSM cellular network.
  • Each traffic violation monitoring unit 106 has a GSM communication module and a SIM card to enable the communication to take place, via the GSM Cellular network, with the A-GPS Server.
  • the Almanac satellite data received from the stationary A-GPS Server enables the D-GPS software embedded within the traffic violation monitoring unit 106 to compute the differential between the traffic violation monitoring unit 106 and the License Holder 104 attached to the motor vehicle 102.
  • Violation information can be transmitted as zipped files and such files can then be stored at a remote secure database (for security reasons). Once the violation information has been transmitted successfully, the traffic violation monitoring module 1 16 can delete the violation information (stored thereon, temporarily) so as to create space within its internal memory.
  • a Dallas key (not shown), or similar technology, is provided on the traffic violation monitoring unit 106.
  • the Dallas key is used for locking and/or deactivating the traffic violation monitoring unit unit 106.
  • the Dallas Key is used by a technician to identify the technician and allow the technician to gain access to certain software elements within the traffic violation monitoring unit 106, record service events, and provide the system administrator with an audit trail relating to the servicing and maintenance of the traffic violation monitoring unit 106.
  • the invention as exemplified is advantageous in that it provides a method 300 and system 100 for detecting a violation of a traffic light in an effective manner.
  • the detection of the violation will deter motor vehicle drivers from violating the traffic light in future because the motor vehicle owner information and motor vehicle information are routed directly to the law-enforcement agency.
  • the method 300 and system 100 will also enable the law-enforcement agency to save time because all the violation information will be routed directly to the agency and thus the agency is also able to issue traffic fines and/or arrest the traffic light violators.

Abstract

L'invention concerne un système 100 pour détecter le non-respect de feu de signalisation par un véhicule à moteur 102. Un module de détermination de non-respect de signalisation 116 reçoit, par l'intermédiaire d'un agencement de communication 118, une localisation géographique du véhicule à moteur 102 et interroge une base de données de périmètre pré-remplie pour déterminer si la localisation géographique reçue correspond ou non à au moins une coordonnée de localisation. La coordonnée de localisation indique une zone de périmètre désignée associée à une unité de surveillance de non-respect de signalisation 106. En réponse à une détermination selon laquelle il existe une correspondance, le module de détermination 106 reçoit un état du feu de signalisation; détermine si l'état reçu correspond ou non à un événement de non-respect; et, si l'état du feu de signalisation correspond à l'événement de non-respect, le véhicule à moteur 102 n'a pas respecté le feu de signalisation.
