Abstract: In order to guarantee the safe operation of PRT scheduling control system, and ensure the convenience and efficiency of PRT′s development and use, security architecture and operation mode of proper PRT system were studied and designed. Based on characteristics and development objectives of PRT system, the functional requirements of scheduling and control system were summarized, a framework with reasonable applicability and reliability was established, the differences of transport elements among different operation modes of PRT system were summed up. Based on the safe architecture, four operation modes were discussed and their safety control flows of the system operation were given for the development of the operational control program. The results show that PRT can undertake the passenger transportation task in regional traffic more effectively depending on the reasonable security architecture and operation mode of dispatch control system.
