<p>A decentralised anti-collision system comprises vehicles 12a, 12b and pedestrians 14 with devices 20 and 18 that transmit their own positions, for example using GPS, with devices 20 also receiving this position information to determine proximity between vehicles 12 and/ or pedestrians 14, allowing the issuing of visual or audible alarms (74, 76 in Fig 3), or disabling or modifying the operation of the vehicle (38 in Fig 2). The system may calculate degrees of danger based on proximity, proximity ranges or zones (46, 50 in Figs 4, 5), and the speed/ direction, number, and/ or identity or type of transmitting devices, where the proximity may also take account of the shape or extremities of the vehicle, and which may be based on data stored in a database (96 in Fig 7), and alert and provide zoned proximity information graphically to the user (42 in Fig 2). The system may be applied at a building or industrial site.</p> |
