Nowadays, due to more concern on global environmental issues, establishing ecological, sustainable urbanism is widely encouraged. To promote safety-assured, mobile communication environments for engaging incorporative knowledge economy and developing contemporary growth poles, efficient, reliable maintenance and information integrity need be concerned, especially in highly possible interfered places. Regular degree-3 dedicated short range communication (DSRC) networks are suggested to support features including availability, reliability, and maintainability on detection-information services along paths of multi-lanes. Applying alternative network topologies, such as spider-webs, generalized honeycomb tori, for comparing, analyzing is proposed in fractal DSRC and cellular communications to enhance integrity in communications, and sustain flexible knowledge infrastructure for long-term economical development.
