one of the first and easiest areas to make smart that is already happening. 1st generation was timed, 2nd generation uses local ambient light sensors; 3rd generation will work as an integrated system, applying light only where and when it is needed.
As utility meter – first electricity, and then water and gas – become smart, i.e. connected with each other, with the grid and with the devices within their metered domain, we will start to optimize usage and efficiencies at a local and global level. The deployment of smart grids is currently outpacing the exploitation of them and opportunities abound.
Traffic congestion, routing and parking
We already see a smart network, as GPS manufacturers start to collate real time data from their customer’s devices and provide traffic monitoring and avoidance services. Smart parking systems are already monitoring their empty spaces. Harvested power sensors built directly into roads will facilitate the next generation.
Infrastructure condition monitoring
The bridge, tunnel and building collapses of the past should become completely avoidable as networked sensor monitor stress and strain and drive safe and efficient maintenance and usage models.
Pollution monitoring & control
Sound, air quality, light, RF, Electro-magnetic. All of these pollution sources will push towards intolerable limits if left uncontrolled. However, smart cities will regulate activity to optimize utility while minimizing pollution. Sensor networks will facilitate planning & development and real time control.
Garbage and sewage systems are inefficient of necessity since zero under-capacity is unacceptable. However, as deployment of local treatment such as compactors and grey water recycling ramps up, garbage management will need to be demand driven, powered by sensing and communication.
A key aspect of all of these smart city systems is the need to collect and communicate data from and to many, many sources and low cost, self powered sensors sensor and control nodes will be an enabling component. Venture is already providing the underlying wireless technology for a number of leading edge smart city projects.
