Data center, which is the basis for the development of transportation information, has the basic function of data storage, processing, data exchange and information sharing. In China, it is a preliminary stage of the design and construction for data center. Difficulties like effective data sharing and executive information service are still exist. In this paper, according to the transmission of data sharing and system architecture design of National Transportation Communications for ITS Protocol (NTCIP) in U.S., the mapping relation between NTCIP and data center architecture is analyzed. The NTCIP-based architecture of data center in transportation information system on freeway is proposed, combined with the information needs of the freeway in Jiangsu Province, China. This study can be used to provide a reference for the data center construction.

The construction of Intelligent Transportation Systems has been increasingly valued by countries worldwide. A proper mechanism for promoting the construction of Intelligent Transportation Systems is very important for the smooth development of these Systems. Based on the construction of Intelligent Transportation Systems in foreign countries, this article intends to analyze the development modes, organizational settings, as well as the formulation of appropriate policies and standards. It then sums up the valuable experience for the construction of China’s Intelligent Transportation Systems.

Researching the development environment (DE) of urban intelligent transportation systems (UITS) can help achieve their healthy and orderly development. This article is based on the development demands of the UITS and gives a summary of the development opportunities and challenges. The analysis shows that the UITS possesses a favorable DE. National and local governments establish a range of policies to promote its development. The existing information facilities and information technology provide powerful support. However, UITS also faces a series of challenges, including management mechanisms, industrial development, availability of capital, and standards.

With the development and impulse of the internet of things technology, intelligent transportation development has entered upon a new rapid development phase. Firstly, this study advanced dynamic sensing stage, active control stage, integrated coordination stage for intelligent transportation development to go through. Secondly, characters and development priorities of each stage was analyzed. Thirdly, some examples were used to summarized that a majority of cities in china are in the dynamic sensing stage expect paucity such as shanghai city. The conclusion of this study will do some help to the development of urban intelligent development in China.

Government departments of different areas are needed during the construction and operation process of intelligent transportation systems. So there is a contradiction that systems must be integrated but they need to be constructed and operated by different organizations. The division of the construction mission among different organization and the rules that all the joint members have to obey should be clear so that repetition and confliction in the whole system can be avoided. These modes of mission division are compared in this paper to provide a reference for our ITS construction and operation mode selection.
