Apparatus for managing and/or monitoring traffic

Field of the Invention

[0001] The invention relates to an apparatus for managing and/or monitoring traffic and in a particular to a modular apparatus for vehicular traffic. The invention has been developed primarily for use as a modular apparatus to manage and/or monitoring vehicular traffic and will be described hereinafter by reference to this application. However, it will be appreciated that the invention may be applicable in other fields, including data collection, especially in outdoor environments, and managing and/or monitoring pedestrian traffic.

Background of the Invention

[0002] The following discussion of the prior art is intended to present the invention in an appropriate technical context and allow its advantages to be properly appreciated. Unless clearly indicated to the contrary, however, reference to any prior art in this specification should not be construed as an express or implied admission that such art is widely known or forms part of common general knowledge in the field.

[0003] Systems and devices have been used to control, manage or monitor traffic, either vehicular and/or pedestrian, especially in urban environments. For example, construction, maintenance or repair in relation to roadworks or streets frequently require traffic to be regulated or controlled for the safety of workers on site and passing traffic. Similarly, traffic may need to be redirected due to an accident or hazard, such as a vehicular accident, a traffic light failure or a train crossing failure. Also, access to a construction, maintenance or other work site need to be controlled for security and safety. All these situations require systems and devices that may readily be installed and removed on-site. Consequently, systems and devices are typically designed to be temporary in nature and so are not permanently fixed to the ground or other permanent structure. Examples of such temporary traffic management systems and devices include barriers (fencing or boom gates), information signs (such a speed limit signs) and other directional markers (such as cones and bollards).

[0004] Consequently, these conventional traffic management systems and devices suffer from several disadvantages due to their temporary nature. In the case of traffic signs, a traffic controller is needed to hold the sign and change the sign between the

STOP and SLOW messages marked on opposite sides to control passing traffic. This poses a safety risk to the traffic controller from passing vehicles and is labour-intensive. Similarly, the erection of temporary barriers like fencing or boom gates requires a considerable amount of time and labour. Also, temporary barriers and signs are subjected to outdoor weather conditions and often collapse or move from their original positions, especially in high winds. In addition, these traffic management devices are frequently unattended during parts of the day and/or night. As a consequence, they are often damaged and/or stolen, requiring replacement and so incurring additional costs.

[0005] In response to these problems, several solutions have been proposed but suffer their own disadvantages and are limited in their function. One solution has been to develop a portable boom gate that can be transported to a work site and operated remotely to control passing traffic. However, this portable boom gate is still quite heavy, at around 90kg, requiring a crane and several workmen to install. The portable boom gate also needs a dedicated truck to transport the portable boom gate. In addition, there are significant work safety risks with lifting and installing a heavy piece of equipment like the portable boom gate. Finally, the portable boom gate also has a tendency to topple in high winds, despite its weight.

[0006] Another proposed solution is a so-called Gibney barrier, which uses a boom type pole with STOP and SLOW messages on either side of a sign. Although intended to merge the function of a boom gate and traffic sign, the Gibney barrier still suffers the disadvantage of requiring a person to hold the pole, and so places the person at risk.

[0007] A further proposed solution is a mobile traffic light unit, where a traffic light with red, yellow and green lights is configured to be foldable or collapsible into a stored state, in which it can be transported in a carry bag. However, this unit is top heavy when unfolded and so needs to be anchored for protection against high winds. Also, the unit does not present a physical barrier to traffic and is reliant on vehicles obeying the traffic light signals.

[0008] It is an object of the present invention to overcome or substantially ameliorate one or more of the disadvantages of prior art, or at least to provide a useful alternative. It is an object of the invention in at least one preferred form to provide a portable apparatus that may be easily assembled and disassembled, is resistant to high winds, improves worker safety and is capable of a variety of functions.

Preferred Embodiments of the Invention

[0065] The present invention will now be described with reference to the following examples which should be considered in all respects as illustrative and non-restrictive. In the Figures, corresponding features within the same embodiment or common to different embodiments have been given the same reference numerals.

[0066] Referring to Figures 1A to 1D and 2, an apparatus 100 for managing and/or monitoring traffic comprises a body in the form of a frame assembly 110 that is configured to mount one or more modules 120, 130, 140 for managing and/or monitoring traffic. Four mass elements in the form of portable batteries 150 are removably connected to the frame assembly 110.

[0067] The apparatus 100 is designed to be portable by being composed of modular components that are easily fitted together and disassembled, making transport, installation and removal of the apparatus 100 convenient and quick, and which can be performed by a single person without requiring any heavy machinery due to the reduced weight of the individual modular components, averaging less than 15kg. As such, the apparatus has a number of modular components that may interact or interconnect with each other, and which are described in more detail below.

[0068] The portable batteries 150 are rechargeable batteries capable of being recharged onsite, either when mounted on the apparatus 100 or removed from the frame assembly 110. The portable batteries 150 arranged such that they lower the centre of gravity of the apparatus 100 towards a base 170 of the frame assembly 110. In this embodiment, the portable batteries 150 arranged adjacent to or at the base of the frame assembly 110. In addition, the portable batteries 150 are arranged around the frame assembly 110 to evenly distribute their total mass. This ensures that the base 170 of the apparatus 100 is kept stable while the concentration of the overall mass of the apparatus is towards the ground, increasing the resistance of the apparatus to shifting or movement caused by high winds or other forces, as well as reducing the risk of toppling over.

[0069] The portable batteries 150 also provide power for the various modules 120, 130, whose operation is discussed in more detail below. As discussed above, the portable batteries 150 can be easily recharged onsite. However, as an alternative, when one of the portable batteries 150 runs out of charge, it can be easily removed from the apparatus 100 and replaced with a fully charged portable battery. The expended portable battery 150 can be recharged later offsite, if required. Thus, the portable batteries 150 have a dual function in providing the necessary mass to stabilise the apparatus against toppling over and high winds, while also providing a power source for the modules 120, 130 mounted to the apparatus. The portable batteries 150 are connected to the module 120, 130 via cables (not shown) that are preferably held within the frame assembly 110. In this embodiment, the module 120 is powered by its connection to the module 130, but in other embodiments may be connected directly to one or more of the portable batteries 150.

[0070] As shown in Figures 2, 3A to 3D and 4A to 4D, the frame assembly 110 in this embodiment comprises two frame members 11Oa, 11Ob, each having side sections 1110, top section 1115, bottom section 1120, middle section 1130 and foot portions 1135 formed by rectangular hollow tubing or members welded together. Alternatively, two or more of the sections may be cast as a single component. The top sections 1115 are shorter in length than the bottom sections 1120, which causes the side sections 1110 to be inclined and the frame assembly 110 to have a larger footprint relative to its head or top. This ensures that the locations of the portable batteries 150 are spread as far apart as possible on the frame assembly 110 at the edges to further assist in lowering the centre of gravity of the apparatus 100.

[0071] The frame member 11Oa has a connecting element in the form of a slot or yoke 1140 formed in the middle section 1130. The slot 1140 is open at one end adjacent the bottom section 1120. Similarly, the frame member 11Ob has a corresponding connecting element also in the form of a slot or yoke 1150 formed in the middle section 1130 but with its open end adjacent the top section 1115. The frame assembly 110 is formed by sliding the frame member 11Oa into the frame member 11Ob via their respective slots 1140, 1150 to create the frame assembly having a cross or X-shaped cross-section. Consequently, the portable batteries 150 are located at the corners of the frame members 11Oa, 11Ob in the frame assembly 110. The frame assembly 110 thus provides sufficient rigidity and support for the modules 120, 130, 140 and portable batteries 150, while remaining relatively lightweight due to its frame-like structure and hollowness of its frame members 11Oa, 11Ob. In addition, the frame assembly 110 has a reduced cross-sectional area and permits air to flow through the apparatus 100, avoiding the risk of high winds lifting the apparatus 100 off the ground or applying sufficient force that could topple it over.

[0072] The frame members 110a, 11Ob also have mounting portions in the form of loops or keepers 1180 for receiving locking members on the modules 120, 130 and portable batteries 150 to securely mount the modules and portable batteries to the apparatus. In this embodiment, there are two loops 1170 on the bottom section 1120 and two loops 1180 on the top section 1115 of each frame member 110a, 110b for engaging the locking members of the portable batteries 150 and the control module 130, respectively. The securing mechanism for the modules 130 and portable batteries 150 is discussed in more detail below.

[0073] Referring to Figures 5A to 5E, a sign module 120 mountable to the apparatus 100 comprises an electronic sign having a frame 1210 and a (preferably LED) screen 1220 for displaying traffic information (such as specifying a vehicular speed) and/or a traffic instruction (such as DETOUR, left or right arrow signs, STOP, SLOW, etc.) to manage or regulate traffic. The sign module 120 has mounting elements in the form of anchor pin sockets 1250 for mounting the sign module to the frame assembly 110, as best shown in Figure 5E. There is also a connector 1260 for removably connecting the sign module 120 to the control module 130, as best shown in Figure 5B. There is a control panel 1270 at the rear of the sign module 120 for manually programming messages for the screen 1220 to display, adjusting the screen display brightness and enabling new messages to be installed via a USB interface (not shown). The control panel 1270 is required for Australian Standards, but may be omitted if not required in other applications (such as controlling access to a property).

[0074] As shown in Figures 6A to 6F, the portable batteries 150 each have a body 1510 and a handle 1520 for carrying the portable battery. There is a channel or groove 1530 in the bottom surface 1540 of each portable battery 150 for engaging the base or bottom section 1120 of the frame members 11Oa, 11Ob of the frame assembly 110. The channel 1530 enables the portable battery 150 to fit over and partly enclose the bottom sections 1120 of the frame members 11Oa, 11Ob. This also permits the portable batteries 150 to sit lower on the frame assembly 110, further facilitating lowering of the centre of gravity of the apparatus 100. A charging dock or plug 1550 for the portable battery 150 is located with the channel 1530. The channel 1530 minimises or prevents the ingress of water and/or moisture into the charging plug 1550, and in some embodiments, the channel may be configured to define a tortuous pathway that further inhibits the ingress of water/moisture. The channel 1530 also has a recess 1560, in which a releasable locking member in the form of an electronic latch 1570 having a ramped surface may extend or retract for engagement and disengagement, respectively, with the loop 1180 on the bottom sections 1120 of the frame assembly 110. The recess 1560 in the channel 1530 ensures that the electronic latch 1570 is protected from damage caused by impacts suffered by the apparatus 100 and cannot be tampered with by unauthorised persons.

[0075] Referring to Figures 7A to 7D, the control module 130 comprises a top cover section 1310 and a body section 1315 within which are stored electronics (not shown) for controlling operation of other modules, such as the sign module 120, and a motor (not shown) for operating a boom connector 1320 connected to the motor via an axle 1325. The boom connector 1320 has a plug 1328 for mounting the boom assembly 140. A recessed portion 1330 of the body section enables a person to carry the control module 130 for mounting to and removal from the top sections 1115 of the frame assembly 110.

[0076] The control module 130 may have other electronic equipment, including a camera, traffic sensor and/or an environmental sensor, as well as antennae for wireless communication. The control module 130 can communicate with a central controller (not shown), portable or handheld device over a secure Wi-Fi, Bluetooth, NFC or other wireless network. The central controller is typically a remote base monitoring controller or system, such as a traffic authority or worksite command station, from which electronic signals are sent to the control module 130 to monitor and/or operate the apparatus 100 remotely. Also, the control module 130 may send data collected from any sensors back to the central controller. The camera may comprise a speed camera or a monitor that scans and/or measures traffic, both vehicular and pedestrian, such as a flow meter. The environmental sensor may detect and/or measure a variety of environmental parameters, such as ambient temperature, pressure and/or pollutants. Generally, pollutants of interest in relation to traffic are air pollutants and may comprise volatile organic compounds that affect air quality, carbon monoxide, carbon dioxide and other particulates. It will be appreciated that the control module 130 may have a combination of these electronics and/or devices, or only have a single electronic component or device. For example, the apparatus 100 may omit the control module 130 and be operated as only an electronic sign using the sign module 120 only. In another example, the apparatus 100 may be configured to operate only as a boom gate, omitting the sign module 120 and limiting the electronics in the control module 130 to only those necessary to operate the boom assembly 140. Similarly, while the control module 130 has a boom lever 1320 for the boom assembly 140 in this embodiment, it may omit the boom lever 1320 in other embodiments.

[0077] As best shown in Figure 7D, a cross or X-shaped channel or groove 1340 is formed in the underside or bottom 1345 of the control module 130. The channel 1340 is X shaped to fit over and partly enclose the top sections 1115 of the frame members 110a, 11Ob. This arrangement assists in securing the control module 130 to the frame assembly 110. In addition, the channel 1340 minimises or prevents the ingress of water and/or moisture into the electrical connections in the form of charging plug 1347. For the sake of clarity, only two charging plugs 1347 are shown, but there may be only one or up to four charging plugs, one for each portable battery 150. In some embodiments, the channel 1340 may be configured to define a tortuous pathway that further inhibits the ingress of water/moisture. Four releasable locking members in the form of electronic latches 1350 having ramped surfaces are located in recesses 1360 formed in the channel 1340 towards each end 1348 of the channel. The latches 1350 operate the same way as the latches 1570 described above in relation to the portable batteries 150; that is, the latches 1350 may extend into or retract from the recesses 1360 to engage the loops 1170 on the top sections 1115 of the frame assembly 110. Again, this locking arrangement has the advantage of protecting the latches 1350 from damage and tampering. In addition, the control module 130 comprises connectors 1380 arranged at opposed ends 1385 for engaging the connector 1260 of the sign module 120. By having two connectors 1380, the control module 130 is able to connect to two sign modules 120 or other module fitted to the frame assembly 110.

[0078] The boom assembly 140 is shown in more detail in Figures 8A to 8C and is composed of three boom sections 140a, each having a transparent section 1410 that can be illuminated by LEDs in different colours (green, red, yellow, but other colours may be used) and an opaque body section 1420. Each boom section 140a has a tongue or plug 1430 for insertion into a receiving member 1440 in the form of a socket of an adjacent boom section to connect to boom sections together and form the boom assembly 140. The boom assembly 140 is connected to the boom lever 1320 by inserting the plug 1328 into the socket 1440 of the boom assembly, as best shown in Figures 9A and 9B. Once connected, the motor operated by the control module 130 turns the axle 1325 to rotate or pivot the boom connector 1320 and thus move the boom assembly 140. Generally, the boom assembly 140 is lowered to a "stop" position to prevent to movement of traffic and raised to a "go" position to allow traffic to pass through. The boom sections 140a to form the boom assembly 140 has the advantages of being lightweight to transport and enables easy repair. For example, if a vehicle breaks through the boom assembly 140, any damaged boom sections 140a can be readily replaced and the boom assembly restored. In contrast, in conventional boom gates, damage to the boom or bar usually requires replacement of the entire boom.

[0079] Figures 10A and 10B illustrate the removable connection of each portable battery 150 to the frame assembly 110. The portable batteries 150 are each mounted onto the bottom sections 1120 of the frame members 110a, 11Ob via their respective channels 1530 so that the loops 1180 on the bottom sections 1120 are inserted into the recesses 1560. An electronic signal is sent to the portable batteries 150 to trigger their respective latches 1570 to extend into the recesses 1560 and engage the loops 1170, securely locking the portable batteries 150 into position. Consequently, the portable batteries 150 cannot be removed from their mounted positions on the frame assembly 110 without receiving an electronic signal releasing the latches 1570 from the loops 1170; i.e. the latches 1570 retract back in the recesses 1560 out of engagement with the loops 1170. The electronic latches 1570 can be operated by the control module 130 and/or an external electronic device that transmits secure (usually encrypted) electronic signals to the latches 1570. The electronic device can be a portable or handheld device and may communicate with the portable batteries 150 over a secure Wi-Fi, Bluetooth, NFC or other wireless network. This secure locking arrangement ensures that the portable batteries 150 cannot be removed by action of environmental forces, like high winds, or be removed from the apparatus 100 by unauthorised persons. It also provides security for the portable batteries 150 so that the apparatus 100 can be left unattended on site without worrying about displacement or theft of any of the portable batteries.

[0080] Figures 11A and 11B illustrate the removable connection of the control module 130 to the frame assembly 110, which is substantially the same as for the portable batteries 150. The control module 130 is mounted onto the top sections 1115 of the frame members 11Oa, 11Ob via its X-shaped channel 1340 so that the loops 1180 on the top sections are inserted into the recesses 1360. An electronic signal is sent from a portable or handheld electronic device to the control module 130 over a secure Wi-Fi, Bluetooth, NFC or other wireless network to trigger the electronic latches 1350. The latches 1350 extend into the recesses 1360 and engage the loops 1180, securely locking the control module 130 into position. Consequently, the control module 130 cannot be removed from its mounted position on the frame assembly 110 without receiving an electronic signal releasing the latches 1350 from the loops 1180. To remove the control module 130, an electronic signal is sent and the latches 1350 retract back in the recesses 1360 out of engagement with the loops 1180. This secure locking arrangement thus ensures that the control module 130 cannot be removed by action of environmental forces, like high winds, or be removed from the apparatus 100 by unauthorised persons. As noted above, this locking arrangement provides security for the control module 130 containing valuable electronics. This means that the apparatus 100 can be left unattended on site without worrying about displacement or theft of the control module 130.

[0081] Figures 12A and 12B illustrate the removable connections of the sign module 120 to the frame assembly 110 and the control module 130. The sign module 120 is fitted to the frame assembly 110 by placing the anchor pin sockets 1250 onto anchor pins 1190 that are either welded to the frame members 11Oa, 11Ob or cast with the frame members. In addition, the connector 1260 on the top of the sign module 120 mates with the corresponding connector 1380 on the control module 130 to secure the sign module to the control module. These removable connections ensure that the sign module 120 is securely held on the frame assembly 110 and to the control module 130. Since the control module 130 is securely locked onto frame assembly 110, the sign module 120 is also locked in place. Consequently, a secure locking member is not required for the connection of the sign module 120 to the frame assembly 110, although in other embodiments a secure locking arrangement may be provided, such as the electronic latch and loop arrangement for the portable batteries 150 and control module 130, or any other secure locking arrangement, such as key locks, combination locks, mechanical locks and electronic locks. Thus, the sign module 120 is secured to the frame assembly 110 to resist removal by environmental forces, like high winds, or by unauthorised persons. Hence, the sign module 120 is protected from displacement or theft and so can be left unattended on site.

[0082] In operation, the apparatus 100 is transported to a worksite in a disassembled or partly assembled state. In its disassembled state, the apparatus 100 is separated into its modular components, being the frame members 11Oa, 11Ob, sign module 120, control module 130, boom sections 140a and portable batteries 150. In this disassembled state, the modular components each weigh no more than 15kg, with the modules 120, 130 and the frame members 11Oa, 11Ob each being around 8kg and the batteries 150 each being around 12kg. Hence, the apparatus 100 is easy to transport to various worksites as required, and does not require a dedicated vehicle for transport.

[0083] Once at the worksite, the frame members 110a, 11Ob are assembled to form the frame assembly 110 and the portable batteries 150 are securely locked to the bottom sections 1120 of the frame assembly. The sign and control modules 120, 130 are then mounted and securely locked onto the frame assembly 110. Finally, the boom sections 140a are assembled to form the boom assembly 140 that is then mounted onto the boom connector 1320 on the control module 130. The mounting of the portable batteries 150 and the modules 120, 130 can be done in any order. These steps are simply reversed to disassemble the apparatus 100 once it is no longer required onsite.

[0084] As can be seen, the apparatus 100 can be quickly and easily assembled. Moreover, due to the greatly lower weight of each modular component, the apparatus 100 can be readily installed or disassembled by a single person, instead of requiring several people and/or machinery to install, thus saving considerable time, labour and expense while improving worker safety. In addition, the various modules 120, 130, 140 may be controlled remotely and so obviates the need to a person to operate the apparatus 100, improving worker safety from passing traffic. Also, the apparatus 100 is versatile in application, as it is capable of a variety of functions based on whichever module is mounted to the frame assembly 110. Finally, the secure locking mechanisms in the apparatus 100 protect the modules 120, 130 and the portable batteries 150 from displacement, loss and/or theft when left unattended.

[0085] It will be appreciated that the body of the apparatus 100 is not limited to the illustrated frame assembly 110, but may include other types of bodies and/or shapes. For example, the body may have a lightweight conical shape like a traffic cone. Alternatively, the body may have a square, rectangular, triangular, octagonal, hexagonal, oval or any other prismatic or polyhedral shape, as well as being partly polyhedral or a combination of two or more polyhedral shapes. For example, the frame assembly 110 may comprise of frame members that form a triangular shape or other polyhedral shape, similar to a tripod.

[0086] Moreover, while the embodiment has been described with a plurality of portable batteries 150, in other embodiments a single mass element may be used and is preferably located towards the middle of the body adjacent to or at the base of the body. In other variations, there may be a mixture of portable batteries 150 and other types of mass elements, such as weights, used with the apparatus 100. In further embodiments, the portable batteries 150 and/or modules 120, 130 may be removably connected to the frame assembly 110 using different locking arrangements, such as hook and eye arrangements, clips, ties, interference fit fastening arrangements and the like, with or without locking features, such as electronic or mechanical locks. However, it is preferred to use secure locking arrangements to prevent displacement or theft of the components from the apparatus 100. Similarly, the portable batteries 150 and/or modules 120, 130 may be removably connected to the frame assembly 110 using fastening arrangements like bolts, screws and nuts, but are not preferred as these arrangements frequently require additional tools, assembly time and/or unnecessary labour.

[0087] While the embodiments have been described in the application of the invention to monitoring and/or managing vehicular traffic, especially alongside a road or street, it will be appreciated that the invention, including the apparatus 100, may be used in many other applications. For example, the apparatus 100 may be used for managing or controlling vehicular or pedestrian access to a private or ticketed event, or access to a private property. In particular, the sign module 120 may be adapted to provide non-traffic related messages, such as identifying locations (toilets, tickets, drink station, etc.) or even provide advertising. Similarly, the apparatus 100 may be used as a mobile remote speed camera with only the control module 130 installed having a speed camera and optionally a number plate recognition camera. Other applications for the apparatus may include a mobile sensor, where the apparatus 100 is fitted with one or more sensors that measure or detect wildlife using an infrared and/or motion camera, pollution, temperature, pressure and a range of other parameters.

[0088] It will further be appreciated that any of the features in the preferred embodiments of the invention can be combined together and are not necessarily applied in isolation from each other. Similarly, features in the embodiment may be implemented separately in other embodiments. For example, the control module 130 can be used without the boom assembly 140 and vice-versa. As another example, a single portable battery 150 may be used in the apparatus 100 with weights being used as mass elements on the apparatus. Similar combinations, modifications or divisions of two or more features from the above described embodiments or preferred forms of the invention can be readily made by one skilled in the art.

[0089] By providing an apparatus 100 with removable modules 120, 130, 140 for managing and/or monitoring traffic and one or more removable mass elements 150, the invention confers the advantages of a portable apparatus that is easily assembled and disassembled and stable in operation. As a result, the apparatus 100 is truly portable, making transport, installation and removal of the apparatus convenient and quick, and which can be performed by a single person without requiring any heavy machinery. In addition, the distributed mass elements 150 ensures that the portable apparatus 100 is stable and resistant to environmental forces, such as high winds. Furthermore, the apparatus 100 is more versatile than conventional traffic management devices or systems as any type of module can be mounted, replaced or added as needed without replacing the apparatus for another unit to fulfil a different function. Also, the secure locking arrangement ensures that the mass elements 150 and modules 120, 130 may be left unattended on a worksite with a reduced risk of displacement, loss or theft. As the modules 120, 130 may be controlled remotely, there is a reduced risk of injury to workers from being struck by passing traffic or heavy machinery. In all these respects, the invention represents a practical and commercially significant improvement over the prior art.

[0090] Although the invention has been described with reference to specific examples, it will be appreciated by those skilled in the art that the invention may be embodied in many other forms.
