Research On Modern Intelligent Transport System Technology Selection Model Based On ICT

The increasing transport pressure as a global issue and the need of sustainable development in the long run calls for Intelligent Transport Systems (ITS) which improves urban transport status quo by intelligent, efficient, safe and convenient ways of traffic management. Information and Communication Technologies (ICT) connect end-users with Transport Information Systems anywhere, at any time and by all means, providing ubiquitous services.However, urban ITS as a large and complex system is difficult to ensure full update in every aspect while the needs of users are constantly changing. (Here, Intelligent Transport System is treated more like a concept than a concrete technology.) Developing technology leads to more increasingly complicated demands which make overhauling the entire system a costly and low-efficient way of updating. To satisfy the growing and changing needs and keep in pace with state-of-the-art ICT, agile evaluation methods for Information Systems are a must in the future.Under this circumstance, traditional evaluation techniques will not be applicable, because establishing a multi-layered scale as a large and complicated project cannot be easily carried out in a short period of time. Even if it can be established, updating the weights will be a time-consuming drudge. Moreover, when the scale is large enough (eg. over 50 items), the discrepancy among weights will be so little that subjective judgments might not be accurate enough. As a result, the thesis puts forward a comprehensive Transport Information System technology selection model that can be adjusted according to needs and the changes of the (economic, natural, cultural, etc.) environmentThe proving and realizing of the model built on this conjecture mainly relies on a combined method of subjective evaluation and objective modification. Data is acquired from a provisional consultant panel and government agencies. The thesis is built on the contrast analysis of the current situation and related literature in China, U.S., Europe and Japan. It closely examines the mainstream evaluation methods in those countries and establishes its own comprehensive evaluation model.
