"Cloud Era" has come quietly.
At present, the fusion of GPS satellite signal and CDMA network signal hybrid positioning technology Gpsone has been widely used by China Telecom in Zhejiang, Guangdong, Fujian and other provinces traffic http://www.aliyun.com/zixun/aggregation/36719.html " > Industry information, for its new generation of location services laid the foreshadowing.

"Super computer" for intelligent transportation

"Cloud computing" originated in the It field, in the intelligent traffic it increasingly obvious today, the Intelligent transportation field of "cloud computing" applications are generally expected both inside and outside the industry.

"Cloud computing" is defined as a network service delivery and use of the model, people through the network on demand, easy to expand the way to obtain the services required, which can be Internet-related software services, but also can be other services, and the provision of resources network is called "cloud."

Through the network, it can automatically break up the huge computing process into countless smaller subroutines, and then send the processing results back to the users after the calculation and analysis. With cloud computing technology, Web service providers can handle tens of millions of billions of dollars of information in a matter of seconds to achieve the same powerful network services as supercomputers.

It is believed that these features coincide with the functional needs of the intelligent transportation services such as "road number, high definition and intelligent". First, the Intelligent Transportation Service should provide the comprehensive road condition, realizes the comprehensive monitoring to the city road traffic situation, the traffic flow information, the traffic illegal behavior and so on, especially in the traffic peak needs to collect, the processing and the analysis massive real-time monitoring data. Second, the Intelligent Transportation Service information dissemination timeliness request is very high, needs the accurate information to send to the different demand main body in time. In addition, the Intelligent Transportation Service system needs to have the high reliability and the stability.

Lack of security is the biggest barrier

However, there are also insiders believe that, because of data security, privacy, confidentiality is difficult to protect, and technical standards are not unified, the Intelligent transportation field of "cloud computing" application may still be in the cloud.

The open nature of "cloud computing" applies to the provision of Web services based software services, but unlike the IT industry, the field of intelligent transportation does not seem so "open."

Taking urban rail transit as an example, the main body of its traditional intelligent Transportation service is subway operation and subway security. The coverage of the monitoring is limited sites and areas covered by the Metro operation, and the video data is highly confidential and secure and does not connect to the public network. In addition, its service object is the subway operator and the Public Security Department, at the same time because its security level request is higher, causes the system to set up the innate barrier in the design.

So even if the monitoring system backend can share "cloud computing" very convenient and powerful search, "cloud storage" and other services, from the Intelligent Transport Services Information security considerations, the current "cloud computing" does not seem to be suitable for the relatively closed traditional intelligent transportation system.
