Heterogeneous sensor integration for intelligent transport systems

Recent advances in electronics and wireless communication systems have brought many different variants of wireless sensor devices (motes) from industry and institutions. As a result the development and deployment of intelligent transport applications has become complicated due to the diversity of sensors and communication protocols available. The Embedded Middleware in Mobility Applications (EMMA) consortium delivers a middleware specification that aims to facilitate the interaction between sensing technologies in intelligent transport systems. This is demonstrated using a wide range of technologies from small scale automotive systems to large-scale road infrastructure systems. This paper discusses our experience of using heterogeneous sensors to develop intelligent transport system applications in the EMMA project and focuses on how cooperation between vehicle and infrastructure can be addressed.
