Abstract: This paper presents a design strategy for system among city vehicles in communication. The system is composed of PowerPC hardware platform and software platform based on embedded Linux operating system. Real-time vehicle location information is obtained by Global Positioning System(GPS) technology. Dedicated Short Range Communication(DSRC) technology is employed to achieve high-speed and two-way interactive communication between city vehicles. ARM9 loaded with embedded Linux operating system plays a role of touch screen display. Test result shows that the system can achieve high-speed, reliable, low-latency communication between vehicles.
