2, the economic system as a whole taking into account the cost of parking and its own characteristics of a long payback period, to meet the performance requirements should be the premise of the whole system can make the greater gains. 3, the reliability must be considered a mature technology and products, equipment selection and system design have to do the most to reduce failure. 4, maintainability, we believe that the current application system maintainability is very important success factor. Maintainability includes the second floor where the meaning of: a. easy trouble-shooting; b. daily management of the operation is simple. 5, security, science and technology with the rapid development and social progress, the modus operandi of criminals all the north face denali of ever-changing. Technology must be effective measures to prevent theft of vehicles inside; the same time, the system must be designed to regulate the operation to ensure system security and insanity workout of their own safety. Thus, security considerations, should be sufficient attention must be used various means and ways to prevent the loss of all forms. 6, the overall integrity of the system, involving all aspects of the system that works co-ordination of these factors must be considered to constitute an organic integrated management system. 7
, the practical design of the system, should be considered first to meet the functional requirements and the practical application of parking requirements, taking the driver out of the convenience and security. 8, open vendor products to ensure the coordination of the operation, taking into account long-term interests of investors mac brushes the system must have a certain openness, combined with relevant international standards or industrial standards. 9, the scalability of the system to consider the future development needs, and therefore must have product lines in the system, capacity and processing abilities of the possibility of expansion and replacement. This expansion not only fully protect the original investment, but also has higher overall cost performance. 10, the normative as the system is a mac makeup system, the system design and construction should begin early reference to all aspects of standards and norms, and should comply with the technical requirements of the specification, good system design and management standardization. Fourth, the overall design specifications and authority: Ministry of Transportation construction standards for the transportation facilities and systems design of an intelligent building design standards as a reference
