基于云服务的交通量计算系统的设计

Design of Traffic Volume Calculation System based on Cloud Services

为了提高交通量数据采集与计算能力,基于云服务设计了一个交通量计算系统,集中处理全市交通量数据.应用了Windows Mobile智能设备开发技术编写了手机端交通量计数器程序,通过3G网络实现了交通量原始数据的上传.在云服务中心,应用了Excel VBA二次开发技术生成了各种统计图表,调查员在工作中,随时可下载统计图,了解交叉口的实时交通流量、流向等数据.实践证明,该交通量计算系统扩展性良好,能应对大城市交通量计算需求,能够推进智慧交通、智慧城市的建设.

In order to improve traffic volume acquisition and computing ability, a traffic volume calculation sys- tem based on cloud services was designed to process the urban traffic volume. In this system, the traffic volume counter program at the mobile-terminal was developed by applying Windows Mobile secondary development technology, and the uploading of raw traffic volume was realized through 3 G network. The Excel VBA seconda- ry development technology was adopted to generate the various statistical charts. During the working process, the investigators can download statistical charts to understand the real-time traffic volume and traffic flow at any time. The practice proves that this system has a good expansibility to deal with the traffic volume processing re- quirements of big cities.
