Vehicular Urban Pollution Monitoring
Vehicles will be the next generation of ubiquitous pollution control system and will eventually take over the large facilities used today. They will be equipped with sensors measuring several environmental characteristics such as CO2 concentration, temperature, black carbon and other pollutants. As the vehicles move around the city they will collect the environmental data, store and analyze the information. Vehicles swarms will be programmed to perform automatic pollution hot-spot detection through cooperative sensing enabling a new generation of pollution management applications. The data gathered by different vehicles can be cross-correlated and geo-tagged on a geographical information system (GIS) in order to track the path of pollutants and track down major sources of pollution.
Intelligent Transportation Systems
The ever-increasing number of private and public vehicles is leading to higher traffic congestion in many urban areas. It is clear that controlling the traffic congestion and optimizing the use of public and private transportation are becoming a mandatory goal for government agencies and policy makers. Vehicles equipped with a GPS can be used as probing sensors that can report on the status of the traffic in each road to a control center either through opportunistic wireless-mesh networks or through cellular networks. The control center will use the real-time information provided by the in-road vehicles to enable and enforce traffic optimization policies through the city-wide street infrastructure.
Location Based Services
Vehicles instrumented with GPS and communication devices will enable a new set of location based services including on-the-go digital billboards, opportunistic advertisement, government-run emergency information. Proximity based services enable cars to gather and deliver to potential customers’ smartphone the latest offers by local businesses. In the event of a typhoon, when the 3G infrastructure is down, a city-wide mesh network and WiFi enabled emergency vehicles could perform tracking and prioritize the rescue operations.
