Abstract
A traffic law enforcement system (18) having one or more enforcement units (20) and decoy units (22), and an engagement mechanism (24) corresponding to each enforcement unit and decoy unit. The enforcement units are capable of vehicle speed detection (30) and identification to enable enforcement of the speed limits by subsequent ticketing. The decoy units have an external appearance substantially indistinguishable from an enforcement unit. Both decoy units and enforcement units are preferably positioned in prominent, highly-visible locations throughout a traffic flow area. The engagement mechanism enables the substitution of enforcement units for decoy units, and vice versa. This enables routine and random exchanging of decoy units and enforcement units which increases the difficulty of a driver discriminating between enforcement units and decoy units, decreasing the number of enforcement units required in the system, and, therefore, the cost of the entire system. The invention provides a means of helping reduce the speed of drivers to safe limits while enabling more effective and safer enforcement of the traffic ordinances by requiring less police interaction and the dedication of fewer police resources, such as police cars and related enforcement equipment. Such a system will play an important role in permitting municipalities to dedicate police resources to the enforcement of more serious criminal laws, or, alternatively, to reduce the municipalities' traffic law enforcement costs.

STATEMENT UNDER ARTICLE 19
Claims 1-4, 6-8, 11-13, 15-20, 23, 24 and 26 as amended more clearly define a traffic law enforcement system and method utilizing remote units in order to more effectively enforce the traffic ordinances. As defined in amended claims 6-12, 20, 24, 26 and 27-28, the invention includes a method of using a system of functional units and decoy units which further enhances enforcement. The functional units further transmit real-time images to an operator/witness at a command station. The witness may be queried to confirm his having witnessed the violation, thus supporting enforcement in court proceedings. The prior art, such as Gross, does not show a comparable manner of using decoy units. Rather, the prior art suggests only that fixed housings may optionally possess components necessary to its function, thus arguably implying that such fixed housing may, at times, not possess such components. The prior art does not show use of decoy units which wholly replace enforcement units. Thus the prior art permits an observer to readily ascertain whether a fixed housing contains a functional camera merely by (a) observing and noting the location of the fixed housings from which cameras are being removed; (b) looking inside of fixed housings through their portals to determine if the camera is missing, or (c) reading newspaper accounts of other persons who claim to have witnessed the removal and installation of cameras from fixed housings at particular locations. By concurrent replacement with another enforcement unit or a decoy unit, the invention thus utilizes decoy units in a manner which helps ensure that no externally distinguishable signs are apparent in a changeout from an enforcement unit to a decoy unit and vice versa. Such represents an important advantage in an age in which information concerning the functional outfitting of a fixed housing is readily available via the Internet or by more conventional means.
The applicant has further amended claims 2, 4, 13, 15, 20, and 23 to recite a violation detection means as opposed to a speed detection system. The change in wording is supported by the specification on pages 17 and 19 which describes use of the invention for purposes other than speed enforcement.
Further, claims 6-7, 13 and 16, as amended, better define the scope of the invention for which protection is sought. These claims define use of decoy units and enforcement units within a fixed housing, such use requiring the concurrent replacement of an enforcement units with a decoy unit and vice versa. Merely failing to functionally outfit a fixed housing is not claimed.
