Description

A TRAFFIC ENFORCEMENT SYSTEM AND METHODS THEREOF

CROSS-REFERENCE TO RELATED APPLICATIONS

[001] This patent application claims priority from US provisional patent

application No. 61/386,528 filed on September 26, 2010, from US provisional patent application No. 61/386,530 filed on September 26, 2010, and from US provisional patent application No. 61/508,644 filed on July 7, 2011 , the content of all of which are incorporated herein by reference in their entirety.

TECHNICAL FIELD

[002] The present invention relates generally to traffic, moving and/or parking monitoring systems, and more specifically to a system for detecting and monitoring of the occurrence of traffic violations and providing respective video and still photographic evidence of the violations.

BACKGROUND OF THE INVENTION

[003] Camera-based traffic monitoring systems are deployed by law

enforcement agencies and municipalities to enforce traffic, moving and/or parking, laws in an attempt to modify unsafe driving behavior and illegal parking. Although video footage has been used for identification and

prosecution of vehicles in violation of traffic laws, prior art solutions cover a low percentage of all traffic violations due to the complexity involved in identifying violations such as lane cutting, unlawful lane crossing, crossing of white lines, blocking a junction, improperly using a public transportation lane, or general reckless driving, as well as parking violations such as blocking a bus stop, parking in a place that obstructs view of a junction, and otherwise not complying with parking regulations. Furthermore prior art solutions are generally static wherein the cameras are affixed in a predetermined location filming a predetermined path in order to locate a predetermined singular type of traffic or parking violation.

[004] Therefore, in view of the deficiencies of the prior art, a system that identifies a higher percentage of traffic violations, and that would be flexibly deployable and efficient to operate, would be advantageous.

SUBSTITUTE SHEE DETAILED DESCRIPTION OF THE INVENTION

[0010] A system and methods thereof for defining, monitoring and reporting incidences of potential traffic violations, motion or parking, utilizing at least video clips thereof, and as necessary still images, is described. The system is an efficient in evidence detection and collection for the purpose of off-line ticket generation respective of traffic violations. The system monitors various types of traffic violation defined at for a particular location or instance and which are usually complex to track. The system maybe stationary, installed for example on a pole, or mobile, installed for example on a patrolling vehicle, or carried by a person such as a police officer or a traffic warden. In one embodiment of the invention the system can also be used for real-time ticketing as well as dispatching a notification to a registered owner of a vehicle.

Reference is made to Fig. 1 where an exemplary and non-limiting block diagram 100 of a basic system according to the invention is shown. The system 100 comprises one or more subsystems 10, each subsystem 10 comprisingat least a camera, for example video camera 120-1 , potentially one or more cameras, for example still camera 1 10-1 , and one or more processors, for example processor 130-1. It should be understood therefore that there may be systems that do not include still cameras as long as the video cameras are able to provide sufficiently high-resolutions to enable legally acceptable enforcement standards. Each subsystem 10 may be independently configured to monitor traffic violations that are specific to the position in which the subsystem 10 is located. This is done be defining the kinds of violations that the subsystem 10 can identify from the data stream from video camera 120. If a potential violation is detected, sufficiently high-resolution evidence of the violating vehicle which is sufficient to enable identification of the vehicle is captured either from a high resolution video stream or from a still camera. The identification of the violation is performed by series of instructions that are executed by the processor 130. Such instructions that are stored in memory (not shown) coupled to the

3

SUBSTITUTE SHEET processor 110 (or in one embodiment integrated therein) enable detection and monitoring traffic violations such as, but not limited to, blocking a junction, lane cutting, lane-to-lane crossing while disturbing traffic, crossing over white lines, driving on the road shoulder, not keeping to the right of the road, dangerous overtaking, tailgating, i.e, driving too close to a vehicle in front of another vehicle, lane blocking, not yielding when so required, not giving the right of way, overtaking from the right when not allowed, running a red light, school bus overtaking, speeding by a predefined threshold speed over the speed limit, failing to maintain safe distance from other vehicles, crossing a railroad crossing when an indication of a nearing train is active, failing to slow or stop at a pedestrian crossing, illegal parking and so on and so forth. Similarly, such instructions enable detection and monitoring of parking violations such as parking or stopping in a restricted area, (such as a no parking zone or a no stopping zone), parking on the curbside, parking on a pedestrian crosswalk, parking on the sidewalk, parking at a bus station and so on and so force. It should be understood that a user interface (Ul) enables the configuration of the system to a particular set of violations and definition the triggering events that lead to an indication of a potential traffic or parking violation. It should be further understood that for each violation there may be one or more video clips and possibly one or more still images associated thereto.

[0011] According to the invention the subsystem 10 communicates with server 160 and database 150 through a network 140 to provide information of a suspect violation which comprises at least one video clip and potentially one or more high resolution images, as well as other data such as time of day, date, location, type(s) of violation, etc. so that such information may be viewed by an enforcement officer. The network may be wired or wireless, and may further be part of a local area network (LAN), wide area network (WAN), metro area network (MAN), a cellular network, the world wide web (WWW), the Internet, local storage to non-volatile media that is later transferred to the enforcement office for further processing and any other network and on-line or off-line data transfer, as well as combinations thereof. The enforcement office may use an enforcement office unit (EOU) 170 to communicate through the network 140 with the server 160 and database 150 for the purpose of retrieving suspect traffic or parking violations. The enforcement officer may view on the EOU 170 the video clip(s) and determine if a violation actually happened and if so determine from the high resolution still images the precise information about the violating vehicle. Upon determination that a violation has occurred a traffic citation (ticket) may be prepared accompanied with the necessary evidence which may now be stored for future use. In one embodiment of the invention the person receiving the citation may receive a web link known as a universal resource locator (URL) to the video clip(s) and the high resolution image(s) so that the violator can view the evidence. In another embodiment of the invention, video clips may be recorded onto video media (such as a DVD) and mailed to the person receiving the citation. In yet another embodiment of the invention the EOU 170 is further capable of receiving from the database 150 data respective of past violations associated with the offending vehicle and allowing the enforcement officer to generate a response that accounts with the violator's history. For example, and without limitations, an enforcement officer may determine that in view of the offender's history and kind of violation that a warning should be generated rather than a ticket.

[0012] Fig. 2 depicts an exemplary and non-limiting flowchart 200 of the configuration of the subsystem 10. In S210 one or more video cameras and potentially one or more still cameras are placed in a desired location. In such a location the subsystem 10 should be able to cover an area where potential traffic violations occur. For example, the camera may be located where it is able to detect a no-cross separation line that may not be crossed. In S220 the subsystem 10 is configured, with respect to the viewing area of its one or more video cameras, to detect one or more potential traffic violations. Once configured, then in S230 the subsystem 10 is activated to be communicatively

SUBSTITUTE SHEET (RULE coupled to the server 160 and database 150 through the network 140 and thus be ready for capturing traffic violations. In one embodiment of the invention the video clips are streamed from the camera to the server, and in the server the stream is recorded in consistent time chunks that have a cryptographic signature attached to them, and are not modified from this point onwards and by that guaranteeing authenticity.

[0013] Fig. 3 depicts an exemplary and non-limiting flowchart 300 of the capture mode of a subsystem 10. In S310 the video camera(s) continuously inputs data to the subsystem 10 and capture high resolution evidence(s). In S320 the system detects, by one or more of the processors of the subsystem 10, one or more traffic violations based on the configuration described in Fig. 2. In S330, if such a violation was detected, the subsystem 10 sends a video clip plus high resolution evidence to the server 160 for the purpose of storage of the potential traffic violation in the database 150. It should be noted, that once a confirmation is received that the information was properly stored in the database 150, the data in subsystem 110 may be erased thereby freeing memory, as noted herein below. In S340 it is checked whether the subsystem 10 should continue capturing and if so execution continues with S350; otherwise execution terminates. In S350 it is determined if older data can be erased from the subsystem 10 and if so data is erased prior to continuation with S310.

[0014] Reference is now made to Fig. 4 where an exemplary and non-limiting flowchart 400 of the citation mode of the system 100 with respect of the EOU 170 is shown. In S410 the EOU 170 retrieves information respective of a suspect traffic violation stored in the database 150. This may include one or more video clip(s) of the suspect violation, one or more still images respective thereof, and as further described hereinabove. In one embodiment of the invention the still camera starts taking still images only after a violation is detected. In another embodiment of the invention the still camera continuously takes still images and if a violation is detected during video clip analysis (realtime or off-line) the system retains the corresponding still images. The information may further include data such as the time and date of the violation, location, audio recordings as may be applicable. For example, in a mobile version of the system, an enforcement officer or a user of the system may record information relating to the violation observed. In S420 the suspect violation is presented to a user, for example, an enforcement officer using the EOU 170. In S430 the user is prompted to decide if a violation actually happened based on both the one or more video clips and zero or more still images. If a violation is detected by the user then execution continues with S440; otherwise, execution continues with S450. In S440 a citation report (ticket) with respect of the traffic violation is issued by the user, e.g., the enforcement officer, to the violator. In S450 it is checked whether the user wishes to store the data provided for future use, for example in database 150, and if so execution continues with S460; otherwise, data is discarded and execution terminates. In S460 the clip and associated data is stored in database 150. Execution may continue therefrom with S410 if additional suspect violations exist or otherwise execution may terminate.

[0015] In one embodiment of the invention the system may also include components that are able to identify vehicle information such as, but not limited to, license plates, colors, make and models of the vehicles in a video clip frame or a high resolution image. Such an embodiment can use these components to annotate the video clip frames and/or the high resolution images. Such annotations may include, for example, pixel geometry of a license plate inside the video frame or high resolution image, and may also include a textual representation of the license plate that is generated by means of optical character recognition algorithms (OCR). [0016] In yet another embodiment of the invention the system is mobile, for example, assembled on a patrolling vehicle wherein cameras can be assembled on at least one side of the patrolling vehicle. The system may be capturing on a continuous basis or otherwise manually activated by a user through, for example, a user interface. Furthermore additional information may be added automatically from Global positioning System (GPS) / License Plate Recognition (LPR) systems, as well as notes and voice recordings.
