摘　　要：为改良和升级现有公交系统,提出了一个具有高性能、高安全性的系统工程设计方案并采用城域网架构系统网络,应用虚拟专用网(VPN)技术保证数据传输的安全性。以J2EE平台为主要软件设计平台,使系统具有较强的可集成性和交互性。根据系统应用模块的特点,采用B/S结构与C/S结构相结合的模式,充分应用了两种模式的优点,建立了典型的安全解决方案,并从4个角度进行了提高系统安全性的设计。A system engineering project with high performance and security is introduced. It has referenced value for the development and update of traffic system in existence. The project adopts MAN （metropolitan area network） technology to construct network. The security of data transmission is protected by VPN （virtual private network） technology. The system takes the J2EE platform as main platform so that it can be easily integrated and communicated with others. The design pattern combines the B/S framework and C/S fra- mework according to the characteristics of the system application modules. A typical security scheme is put forward. And from four angles there is a design for enhancing the security of the system.
