A system for managing vehicular traffic flow within a road network

摘要

A system for managing traffic controlled by sets of traffic signals 11, within a road network, comprising sensors 12 located at various points 13 within the network, each sensor being adapted to detect passing vehicles 14, and which vehicles are carrying a Bluetooth or WiFi enabled device 15. Each sensor communicates with a data server 16 which collates data from all the sensors to generate and store an overall picture of traffic flow across the network; the signal phase of each traffic signal within the road network can then be adjusted in near real time to optimise traffic flow. A vehicle equipped with a Bluetooth or WiFi device can have its unique MAC address recorded by the sensor and its subsequent progress tracked to identify busy or frequently used routes; the traffic signals on these routes can then be adjusted to optimise traffic flow. The sensors can be easily integrated with existing traffic light signal control units.
