Wireless mesh networks (WMN) have attracted consider- able interest in recent years as a convenient, flexible and low-cost alternative to wired communication infrastructures in many contexts. However, the great majority of research on metropolitan-scale WMN has been centered around max- imization of available bandwidth, suitable for non-real-time applications such as Internet access for the general public. On the other hand, the suitability of WMN for mission- critical infrastructure applications remains by and large un- known, as protocols typically employed in WMN are, for the most part, not designed for real-time communications. In this paper, we describe the Smart Transport and Roads Communications (STaRComm) project at National ICT Aus- tralia (NICTA), which sets a goal of designing a wireless mesh network architecture to solve the communication needs of the traffic control system in Sydney, Australia. This sys- tem, known as SCATS (Sydney Coordinated Adaptive Traf- fic System) and used in over 100 cities around the world, connects a hierarchy of several thousand devices — from in- dividual traffic light controllers to regional computers and the central Traffic Management Centre (TMC) — and places stringent requirements on the reliability and latency of the data exchanges. We discuss our experience in the deploy- ment of an initial testbed consisting of 7 mesh nodes placed at intersections with traffic lights, and share the results and insights learned from our measurements and initial trials in the process.
