Abstract
Communication between a traffic speed limit sign 1 and an oncoming vehicle wherein the vehicle is detected 4; a signal is transmitted from the sign to a receiver on-board the vehicle; and information is displayed inside the vehicle in response to the transmitted signal. Motion of the vehicle toward the sign may cause the signal to be transmitted. The signal may comprise speed information, e.g. the speed limit 7 displayed on the sign, which may be displayed in the vehicle. The arrangement may be powered by a solar panel at the rear of the sign. The solar panel 6 and transmitter 5 may be located at the rear of the sign such that the vehicle receives the signal when it enters the area governed by the sign-posted speed limit.
Description
tM:;: INTELLECTUAL .*.. PROPERTY OFFICE Application No. 0B1221569.5 R'T'M Date:21 March 2013 The following terms are registered trademarks and should be read as such wherever they occur in this document: ZigBee, Bluetooth Intellectual Properly Office is an operaling name of Ihe Patent Office www.ipo.gov.uk -1** lv Traffic Speed LirnJ.t,igfl.unicatiqmS,ystemsancJN1thocis tIie The invention reLates to traffic speed limit signs, communication systems and methods of communication.
ckgtoindtothlnvent, The closest prior art known to the applicant is satellite navigation technology which is able to inform drivers of the speed iimit of the road they are driving or. However, the disadvantage of this is that this technology requftes frequent updates from the Internet so that speed limit change.s are kept current, These systems cannot take account of temporary speed limit changes such as changes due to road works or pubOc events.
Other prior art known to the appLicant are traffic signs that use radar to detect oncoming vehicLes and a warning is given to an over speed vehicle to remind a driver of the speed limit The disadvantage with these signs is that the warning is observed only outside of the oncoming vehicle.
wanQLbeJnention n the first broad independent aspect the invention provides a traffic speed limit sign comprising a communication system; said communication system incorporating a detector a for detection of an oncoming vehicLe; and a transmitter for communicating to said vehicle; whereby the motion of said vehicle toward said traffic sign activates said communication system; whereby activation of said communication system causes said transmitter to transmit a signal to said vehicle in order to display information inside said vehicle.
iv The advantage of this sign is that ft provides the driver of a vehicle with clearer speed Limit information when the vehicle is passing a particular area, Additionally, the speed limft can be kept up to date to take account of changes due to road works or public events. The clearer speed limit information ensures that a driver is more likely to respond to a change in speed limit of a road.
PreferabLy, said traffic speed hmft sign is further powered by a solar panel that is Located at the rear of the sign. This configuration provides a low maintenance, preferably monolithic and compact sign.
Preferably, said transmitter for communicating to said vehicle is located at the rear of said sign. This provides the means of transmitting a signal to said vehicle once it has passed said sign in order to be received and displayed inside said vehicle whilst it is inside the designated speed limit zone.
PreferabLy, a communication system comprises a traffic speed Limit sign and a vehicle which comprises a receiver, for receiving said signal and a display unit for displaying information inside said vehicle following the receipt of the signal.
This configuration is advantageous because ft enables the communication of speed information between the traffic speed limit sign and an oncoming vehicle so that speed information can be displayed inside said oncoming vehicle, Preferably, a method of communication between a traffic speed Uniit sign and an oncoming vehicle, comprising the steps of; detecting an oncomhng vehicle; transmitting a signal, containing speed information, to a receiver of said vehicLe and displaying the transmitted signal inside said vehicle. This is advaritageou.s because the transmission of a signal, incorporating speed information, to an oncoming vehicle allows the driver of said vehicle to more easily view the speed information of the road. This is especially significant where the speed information is temporary due to changes such as road works or public events. Communication received inside said vehicle will be advantageous over speed limit information displayed outside of the vehicle.

scritionfeFitjres Figure 1 shows the front of a traffic speed limit sign.
Figure 2 shows the back of a traffic speed limft sign.
ikigdDescrIt4!f the Figi Figure 1 shows a traffic speed Limit sign indicated by 1, which incorporates a head unit 2 and a support post 3. Said head unit comprises a front face, facing towards an oncoming vehicle, and a back face, facing in the opposite direction to the front face, Said front face incorporates a visual indicator comprising LEDs 7. Said visual indicator illustrates the speed limit of a particular area of road. Joining said front and back faces is at least one panel comprising the top, bottom and sides of said head unit. Where the front and back faces of the head unit are circular, only one side panel will be present. Where the front and back faces of the head unit are triangular, there will be three side panels. Where the front and back laces of the head unit are square, there will be four side panels. The traffic speed Limit sign also incorporates a support post 3, located at the bottom of said head unit Said support post fits into said head unit and extends down towards the ground so it may offer so support to the traffic speed limit sign. The head unit incorporates a detector 4. The detector is positioned so that it laces in the same direction as said front face of the head unit. The detector is positioned so that, in use, it can detect a vehicle moving towards the front face of the traffic speed Limit sign.
FIgure 2 shows a traffic speed limit sign 1 from the rear, facing towards the back fact The traffic speed Limit sign incorporates a transmitters, and a solar panel 6. The communication system incorporated into said traffic speed Limit sign is powered by said solar paneL Power may be stored in a battery or by similar means. Said solar panel is attachedtoand isthesameshapeasthebackfaceofsaidhead unitandfacesawayfrom said sign. Said transmItterS, is located at the rear of said sign. it faces in the same direction as the back face of said head unit so that It may effectively communicate with vehicles that have passed said sign. Detection of an oncoming vehicle by said detector 4 causes the proliferation of a signal, containing speed information, from the transmItter 5.
io Communication of said signal may be proliferated via radar, Bluetooth, radio-frequency identification (RFID), ZigBee or other wireless methods. The communication of said signal is directed towards a receiver incorporated in said oncoming vehicle. Said receiver subsequently sends said received Information to a display unit within said vehicle. Said display unit may comprise a satellite navigation system or heeds-up-display unit.
Claims (6)
- Cairns 1. A traffic speed limit sign comprising a communication system; said communication system incorporating a detector for detection of an oncoming vehicle; and a transmitter for communicating to said vehicle; whereby the motion of said vehicle toward said traffic sign activates said communication system; whereby activation of said communication system causes said transmitter to transmit a signal to said vehicle In order to display information inside said vehicle.
- 2. A traffic speed limit sign according to claim 1, wherein said communication system is powered by a solar panel, Located at the rear of said sign.
- 3. A traffic speed limit sign according to either claim 1 or claIm 2, wherein said transmitter for communicating to said vehicle is located at the rear of said sign.
- 4. A communication system comprising a traffic speed limit sign In accordance with any of the preceding claims; and a vehicle which comprises a receiver, for receiving said signal and a display unit for displaying information inside said vehicle following the receipt of the signal
- 5. A method of communication between a traffic speed limit sign and an oncoming vehicle, comprising the steps of: * detecting an oncoming vehicle; * transmitting a signal, containing speed information, to a receiver of said vehicle; and * displaying the transmitted signal inside said vehicle.
- 6. A traffic speed limit sign substantially as herelnbefore described and/or illustrated in any appropriate combination of the accompanying text and/or figures.
