面向城市道路交通的传感器组网优化
Urban road traffic oriented sensor networking optimization
摘要
Abstract
The spatial distribution characteristics of traffic information were given and the sensor information value was put forward. Then the sensor networking problems were solved and the networking optimization objectives were formulated according to physical distributions of traffic sensors. An approach for optimal dynamic networking of traffic sensors was proposed based on the spatial distribution characteristics and the value of traffic information. An application example indicates the procedure is realized and proves the effectiveness of the approach proposed. The results suggest that when 12 sensors are selected for networking, the maximum integrated value is 553.442 yuan/h and the optimal networking result is obtained. The model can realize the dynamic networking of traffic sensors and can obtain the reasonable networking effect.关键词
