Description

MOBILE TRAFFIC ENFORCEMENT DEVICE AND SYSTEM
FIELD OF THE INVENTION
The invention relates to a mobile device for monitoring vehicles and traffic flow along a 0 stretch of road, and in particular, to a device for determining the speed and position of said vehicles and determining if said vehicles are exceeding traffic speed limits, and, if said limits have been exceeded, ticketing said violators through an automated traffic enforcement system.
> · BACKGROUND OF THE INVENTION
Motor vehicle accidents and collisions result in losses of both a financial and personal nature, the very extreme of these resulting in the loss of human life. In an attempt to curb such losses, both financial and personal, governments introduce traffic laws and rules to be adhered to by individuals while using the roads and driving their vehicles. These laws can carry strict penalties to transgressors and serve as deterrents to individuals who will violate or break these laws.
One of such laws, set by governments, is by introducing a speed limit. These limits dictate the maximum, and in some places minimum, speed at which vehicles may travel · along a stretch of road. The limits, while put in place for the well-being of the individuals, are often violated by individuals exceeding the maximum speed limit.
Stationary speeding cameras are used to detect vehicles exceeding speed limits. These devices include a radar arrangement for measuring the speed of the vehicle, and an imaging device for capturing an image of the offending vehicle. The image is transmitted to a hub for processing, after which the offenders will receive a fine or warrant for violating such laws. Additionally, portable speeding devices exist, such as radar guns, which are operated by traffic officers. If a violation is detected the officers commonly flag down the offending vehicle and issue such fine, or may even arrest an offender, on the 7 · spot.
While these techniques do help to curb speeding, they are limited in their physical presence. And hence violators often continue to speed in places were cameras, or traffic officers are not present. This presents a problem as individuals quickly become accustomed as to the whereabouts of such devices. Thus, the efficacy of these devices in reducing the traffic violations is greatly reduced as the individuals avoid these devices.
OBJECT OF THE INVENTION
0 It is an object of the current invention to address these problems, at least partly, and provide a traffic monitoring device which is not limited to a particular physical location, the device being configured to communicate speed limit violations to an authority for ticketing or further processing, so as to condition an individual’s behaviour when it comes to obeying speed limits.

x . BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to Figure 1 which shows a block diagram of the mobile traffic enforcement device 10, in accordance with the invention.
The device 10 may be adapted to be mounted to any vehicle, and the vehicle will be referred to as the host vehicle. The device is mounted to the host vehicle so as to detect the presence, and relative speed, of other vehicles within the vicinity of the host vehicle. These other vehicles will be referred to as the target vehicle or vehicles. The use of the singular vehicle includes the plural, vehicles. Device 10 is made up of a plurality of components 12, which are brought together in a conveniently sized housing. The specific type of housing depends on where the device is mounted on the host vehicle.
0 In one embodiment, the device 10 is mounted within the host vehicle, for example - on the vehicle’s front dashboard, with a front side facing forward, i.e. outward of the windscreen. In a further embodiment, the device may be mounted to the exterior of the host vehicle, such as on the roof of the vehicle. In the latter embodiment, the device would still have a front side facing forward.
i .
Turning to the components 12 of the device 10.
The components 12 comprise a detection and ranging sensor 14, as well as a digital imaging device 18, such as a digital camera. Preferably, these components would be positioned to the front side of the device, in particular the detection and ranging sensor and digital imaging device would face the forward direction.
Further components 12 of the device include, a global positioning satellite module 20, and an information transmission system 22.
x .
Placed in communication with each of the components 12 is a central processing unit 24. The unit includes a memory 26 for storing data. The unit is further connected to a power source 28 for powering the unit and thus, the device 10. The power source may include a rechargeable energy storage arrangement, or may include a connection to the host 'ί 0 vehicle for providing power.
The device 10 also includes an electronic display 30, which provides a graphical user interface. The display may allow for a user to interact with the device, so as to communicate, control, and program the device. Alternatively, the device is controllable 7 · through an accompany mobile application (“app”).
The graphical user interface may include such features as; a live map tracking showing the position of the host vehicle, the current road name and posted speed limit, and the target vehicle or vehicles.
TO
In use, the device 10 is placed in communication with a remote server 32 and a central processing hub 34. The communication is facilitated by the information transmission system 22. In use of the device 10, each of the components 12 and the remote server 32 and central processing hub 34 will come together to identify a target vehicle and determine whether the vehicle is travelling in excess of a posted speed limit while traveling along a stretch of 0 road. If the target vehicle is deemed to be speeding, the information of this violation will be transmitted to a traffic enforcement authority for further processing or ticketing of the target vehicle.
Turning to Figure 2 which illustrates the device 10 in use, while the host vehicle is i · traveling along a stretch of road. The use of the device 10 is broken into a series of steps.
Each of which are set out and described below.
The device is powered using the power source 28.
Step 1 : The detection and ranging sensor 14 begins scanning the road to detect the presence of other vehicles. The detection and ranging sensor will detect target vehicle or vehicles. In this description, the scanner has detected the presence of three target vehicles, target vehicle A, target vehicle B and target vehicle C. Each of the vehicles A, B and C are traveling at different speeds along the road
x .
Once the vehicles A, B and C have been detected they are deemed to fall within a detection area. The detection area is defined as the range to which the detection and ranging sensor 14 can detect the vehicles. Within the detection area each vehicle is tagged by the device 10.
A vehicle’s ‘tagging’ may be based on any number of factors and may include the vehicle’s shape, colour, size, length, width, relative distance from host vehicle, relative angle from host vehicle, or any other identifier which separates and identifies each vehicle.
.
A tagged vehicle will only have its speed detected once, while within the detection area. Thus, a vehicle constantly accelerating away from the host vehicle, and therefore deemed to be continually exceeding the speed limit, will only receive a single violation. Until such time as the vehicle exits the detection area. Should the same vehicle re-enter the 7° detection area, it will be subject to a new detection and receive a new tagging. The vehicle may then be deemed to violate the speed limit, should it once again exceed the speed limit. Step 2: The speed of the host vehicle may be determined. This step may be done in more than one way. One approach may be by connecting the device 10 to the vehicles speedometer system. The speed data may then be extracted directly from the vehicle’s system and fed to the device 10.
Alternatively, the device may provide for the detection and ranging sensor 14to be directed to the ground surface immediately before the host vehicle. The sensor, employing doppler like calculations, will thus determine the ground speed of the host vehicle by measuring the rate at which wave signals are returned to the sensor.
i .
Alternatively still, the global positioning satellite module 20 may be used. The module may determine the location of the host vehicle using global satellite positioning systems, determine the speed at which the vehicle is traveling, and feed this information back to the device 10.
1 o
Step 3: The detection and ranging sensor 14 will then determine the speed of each of the vehicles A, B and C. The sensor will determine the speed of the target vehicles by comparing their respective rates of deceleration or acceleration relative to the speed of the host vehicle.
x .
Step 4: The speed of the host vehicle, as measured in one of the suggested methods, and the relative speed of the target vehicles A, B and C, as measured by the detection and ranging sensor 14, are then fed to the central processing unit 24. All this speed data is then held by the processing unit.
During the detection of the relative speeds of the target vehicles A, B and C as well as the speed of the host vehicle, the device 10 will be determining the speed limit for that stretch of road.
7 · Step 5: The speed limit on the stretch of road is determined by first having the global satellite positioning module 20 obtaining the geoposition of the host vehicle (and hence the target vehicles). This information is then fed to the central processing unit 24.
Step 6: Once the geoposition has been determined (Step 5) the central processing unit 7° 24 will instruct the information transmission system 22 to communicate with a remote server 32 to determine the speed limit along the stretch of road, i.e. at that geopositioned location. The remote server may already include the speed limit information, through a geo-fencing protocol, or alternatively may be accessed by performing an internet based search, further by accessing an internet-based map provider search.
The information on the speed limit is then fed back to the central processing unit 24. The speed limit on that stretch of road has now been communicated to the central processing unit. Speed limit data will be cached locally on the system’s servers, such that speed data is first retrieved from the server before accessing the internet or internet-based map provider. · Step 7: The central processing unit 24 will then run an algorithm to determine whether, and which of, the target vehicles A, B and C are speeding and hence violating the speed limit.
The algorithm is based on using the speed of the host vehicle (Step 2), and measuring 0 the relative speed of the target vehicles (Step 3). The actual speed of the target vehicles is thus calculated (Step 7). This information is then compared with the speed limit data (Step 5 & 6).
Therefore, if the speed of the target vehicle (Step 7) exceeds the speed limit on that · stretch of road (Step 5 & 6) the target vehicle will be deemed to have violated the speed limit.
A target vehicle found to have violated the speed limit will be measured as step 7 (Step 7).
In the current description, and for the purpose of illustration, target vehicle B has been deemed to have violated the speed limit. Target vehicles A and C were not found to be speeding. · Steps 8 to 12 take place once it is determined that Step 7 has occurred.
Step 8: Footage of the target vehicle, in this discussion target vehicle B, which was deemed to be exceeding the speed limit must be documented. 0 The documentation process involves recording footage of vehicle B by way of the imaging device 18. Central processing unit 24 will activate the imaging device to record images and/or a video of the vehicle, thus the footage. The digital imaging device 18 will pass the recorded footage of vehicle B back to the central processing unit 24.
The imaging device 18 is programmed to ensure that the license plate details of the target vehicle are included in the recorded footage. The details of the vehicle license plate are important when the recorded footage is to be further analysed at a later stage in the process.
In order to conserve operational energy and storage of the device 10, digital imaging · device 18 will only be activated, and thus draw power to record footage, once a command is received from the processing unit 24. Such command, will only be forthcoming once it is determined that a vehicle has been deemed to be speeding. Once the recorded images of the vehicle have been passed back to the processing unit, the imagining device will be deactivated and thus, not draw power or storage space until again activated.
o
Step 9: The recorded footage will then be communicated to the central processing hub 34 from the central processing unit 24, via the information transmission system 22.
If, the information transmission system is not within range and cannot communicate with · the processing hub, the recorded footage with be stored within the memory component
26. The communication will be continually attempted until such time as a transmission link can be maintained for transmitting the recorded footage.
Step 10: The recorded footage, as received at the central processing hub 34, are then analysed. The analysis will include the identification of the vehicle license plate details. This process may be a manual process, or may be automated using a type of detection system applied to the recorded footage (this is what is known as automated number plate recognition). · Step 1 1 : Once the details of the license plate of the speeding target vehicle B have been determined, this information will be passed to local authorities for further processing. Such further processing may include ticketing the owner of the target vehicle.
Optionally, Step 12: This provides an incentive for the user of the device 10. Identification° of a target vehicle, which has been deemed to be speeding according to the steps set out above, will generate a reward to the user of the device. This reward may be monetary in form, or may include certain other concessions provided by the local authority. This reward is then communicated, and/or applied, to the user of the device 10, through the electronic display 30 and/or through the mobile‘app’. . Alternatively, the reward is communicated, and/or applied, to the user in a manner suitable for receipt by the user. Figure 3 illustrates the process of determining the speed limit along a stretch of road. This information is then combined with the detection and ranging sensor data set to determine if the target vehicle is deemed to be speeding.
The Global positioning satellite module 20 will determine the geoposition of the host · vehicle. This is done by trilateration of the device 10. Block 100.
Once the location of the device is known, the central processing unit 24 will instruct the information transmission system (GSM module) 22 to communicate with the remote server 32 to determine the speed limit along that stretch of road. Block 101 .
o
If not, the remote server 32 will look to a Speed limit violation cache 36 to determine the speed limit along that stretch of road. The speed limit violation cache comprises a repository of previously saved speed limit data for the position of the host vehicle. This data is saved for a defined period. Once the period expires the data is lost and the · system will be prompted to retrieve the data from the internet or internet-based map provider (discussed below). If the speed limit is known, it will be transmitted back to the remote server 32. Block 102a.
If not, the remote server 32 will look to a RadarX Web API 38 to determine the speed 0 limit along that stretch of road. If the speed limit is known, it will be transmitted back to the remote server 32. Block 102b.
If not, the remote server 32 will look to custom geo-fencing data 40 to determine the speed limit along that stretch of road. The geo-fencing data comprises manually defined · speed limits through a map interface. The borders of each‘fenced’ area are drawn and labelled, both title and speed. This data will override the cached and internet based data. If the speed limit is known, it will be transmitted back to the remote server 32. Block 102c.
If not, the remote server 32 will look to a custom internet search 42 (such as Google° Maps ®) to determine the speed limit along that stretch of road. If the speed limit is known, it will be transmitted back to the remote server 32. Block 102d. The remote server 32 will then communicate with the information transmission system 22 to provide the speed data. The speed data will then be passed to the central processing unit 24. Block 103.
0 The received speed data is then used to determine whether the target vehicle is speeding, by exceeding said speed limit.
Further, speed limit data which is acquired either through the RadarX Web API 38 (Block 102b), custom geo-fencing data 40 (Block 102c) or the custom internet search 42 (Block i · 102d) will be fed to the remote server 32, to update the server with the new speed data for that stretch of road. Block 104.
Turning to Figure 4 which shows the process of recording the footage of the target vehicle, when the vehicle is speeding.
1 o
Information of the speed limit of the stretch of road, and the speed of the target vehicle is known. Footage will only be recorded once it has been determined that the target vehicle has exceeded the speed limit for that stretch of road.
'ί · Prior to the determination of excess speed by the target vehicle the detection and ranging sensor 14 will continually monitor the speed of the target vehicles. This speed data forms a dataset. The analysis of the dataset is placed on a loop. Should no speeding be detected, the dataset will contain no records, and no further action is taken. The analysis will then loop and continually repeat. This is shown by block 200.
If however, a target vehicle is deemed to be speeding, the dataset will return with a dataset that contains records. Block 201 . The dataset is sent to the central processing unit 24. Block 202.
7 · The central processing unit activates the digital imaging device to begin recording the footage of the target vehicle. The command to record images is placed on a loop, if the imaging device does not record, the command will continually repeat. Block 203.
The digital imaging device records footage of the target vehicle. The recorded footage 7° form a New Dataset. Block 204. Recording continues until stopped by processes in Block
205. Once the New Dataset is complete, recording is terminated and the digital imaging device 18 is deactivated. Command to deactivate imaging device is placed on a loop and continually repeated until device 18 is deactivated. Block 205.
0 The central processing unit 24 will process the New Dataset. The New Dataset is passed to the data transmission system 22 for transmitting to a central processing hub 34. Block 206.
The central processing unit 24 will pass the New Dataset to the memory component for 1 · storage. Block 206.
Memory unit 26 will pass New Dataset to data transmission system 22, when transmission to central processing hub 34 fails. Block 207. The passing of the New Dataset is placed on a loop until transmission link with central processing hub 34 is i 0 possible, and the New Dataset has been transmitted.
Central processing unit sends notification to electronic display 30 (once New Dataset transmitted). Notification is additionally forwarded to mobile application (‘app’) provided by the system. Block 208.
x .
Instruction to restart radar speed analysis (loop 200) takes place. Block 209. The instruction as set out in Block 209 takes place during, and at any stage through blocks 200 to 208.
