EMMA - Environmental Monitoring in Metropolitan Areas


Motivation

Area-wide measurements of air pollutions become important to municipal authorities due to several national and European climate directives. Nowadays, air pollution in metropolitan areas is measured with the help of few fixed measuring stations. Afterwards, the measured values are projected on larger areas.

The goal of EMMA is to develop a decentralized and cost- efficient architecture for area-wide measurement of air pollutants. Vehicles of existing public transportation systems are used to continuously acquire environmental data. The measured values are exchanged between different vehicles with the help of WLAN. Since vehicles only meet each other sporadically, techniques from the fields of Car2X communications and Delay Tolerant Networks are used for data exchange. The measured value are delivered to a central gateway which forwards the messages to the evaluation server. Here, they are analyzed and any actions like bans on driving may be taken if necessary. The results of several measurements in the city of Braunschweig showed that the concept of exchanging information between vehicles works very well. Communication is possible even without direct line out sight and at higher distances between the vehicles. Besides distributing measurement values, the architecture of EMMA may also be used for e.g. the exchange of passenger information.
