There is an increasing amount of road furniture appearing on the highways. This is mainly to assist drivers to be responsible and drive in a manner conducive to safe and efficient travel. In instances where it is deemed that some form of additional information or regulation is required, the general process is to either add a speed camera, add a sign, or add warning paint markings. Inefficiencies with these solutions, such as expense to apply these bespoke solutions and the potential for road users to ignore these different types of warnings present the need for a standardised warning system for various situations that road users are less likely to ignore. In some way this has been attempted on motorways with overhead signs that may show a multitude of different information items, from lane closed to "do not drive tired". These signs are controlled by a central authority, and have can only change upon instruction.

Driver Information Based Upon Wireless Network Field Disturbance

Herein disclosed is the use of modified cat eyes such that they may be used for multiple applications, but all based upon the same principle. Example applications for the modified cat eyes disclosed include anonymous average speed checking of any vehicle, warning if a vehicle is too close to the vehicle in front, warning of an

approaching vehicle on a blind corner or if a vehicle is exceeding the speed limit, amongst other applications. Additionally the system can be used for:

Driver aid systems for "staying within the lane" when lane markings are not

visible (glare/fog/snow)

Assistance to autonomous vehicle navigation
Recording dangerous driving for suitably equipped vehicles
Proving safe driving behaviour for suitably equipped vehicles (able to provide more comprehensive driver statistics to insurance companies than GPS tracking alone)

Determining the current location on the road network for a suitably equipped vehicle (without the need for a GPS tracking device)

    The above objectives are achieved by modifying the cat eyes such that they are each wirelessly enabled and are linked by such a wireless network and have the ability to change their reflective or emitted colour. Through detection of the modified

wireless field, inference of passing vehicles may be made. Since all cat eyes are linked, information may be passed up/down the network to relay pertinent information.

    Based upon the manner in which the wireless field is disturbed, and/or information passed to the cat eye, the cat eye may modify the reflected or emitted colour such that it may indicate a warning to an approaching vehicle. Replacement of existing road infrastructure to use such devices would enable an increase in driver or vehicle information, without the associated increase in road clutter. Additionally, such a system would be future proof in that they could enable extended operational capability with the aforementioned abilities listed earlier.

    Such modified cat eyes are an additional means of providing continued speed limit or proximity to other vehicle violation guidance to a driver, effectively combining distancing and average speed checks with a visual warning system. Whilst this currently operates without the requirement of number-plate recognition or radar, it is not infeasible that the cat-eyes incorporate a visual sensor that may be used for number plate recognition, which would enable identification of passing


    The system herein takes advantage of known wave field disturbance technology, with examples of such technology being shown in whole home gesture

recognition using wireless disturbance (1) and commonly available colour changing LEDs and heat and temperature sensors. It is assumed that the cat eyes are able to communicate via an established wireless mesh network. This mesh network is used both to communicate as the field that is monitored to infer passage of vehicles.
