摘要:
系统由现场交通流采集系统和远程数据处理中心两部分组成。现场交通流采集系统采用基于GMR的地磁式车辆检测器作为交通流数据检测传感器,各设备之间采用无线自组网方式进行数据传输。远程数据处理中心与现场交通流采集系统通过GPRS或3G通信,可实现交通流数据远程集中控制和管理。本系统环境适应性强,安装维护方便,具有一定的实用价值。

Abstract: Through analyzing the characteristics of various traffic flow data detection methods and the envi-ronment of the expressway traffic, this paper designs the expressway traffic flow surveillance system which includes live traffic flow data acquisition system and remote data processing center. Live traffic flow data acquisition system uses the vehicle detector based on GMR as traffic flow sensors. With GPRS or 3G network, traffic flow data are transmitted to remote data processing center which can realize the centralized control and management for the data of traffic flow. This system has environment adaptability and high detection reliability, and can be applied to ex-pressway network traffic guidance and effective emergency evacuation.
