Abstract


Traffic signal control is through the control of the traffic flow to improve the safe transport of people and goods, improve the efficiency of operations. Transportation system is a randomness, fuzziness and uncertainty of complex systems, the mathematical model is set up very difficult, sometimes even unable to use existing mathematical methods described. At present domestic intersection traffic light control is generally timer switch control. In today's rapid development of society, traffic problem becomes the social problems of attention, the number of cars soared and the existing limitations timer switch control of the means of transportation has made it necessary to seek a kind of intelligent traffic control system, based on the idea of this paper is: through the detector (that is, the electromagnetic induction coil) detect car traffic automatically adjust the length of the traffic lights. Vehicle traffic counts, traffic lights time control can be made of a programmable controller (PLC) to achieve.
