Abstract:
A promising approach for future road construction is based on a surface which is manufactured in a production plant and can be unrolled on a conventional base. This paper deals with the idea to make the road "intelligent" by integrating a net of sensor nodes. Equipped with acceleration sensors the sensor net can detect the traffic situation. With the knowledge of the exact position and velocity of each car a driver assistance system is able to find the fastest route or to give an accident warning on a very reliable level. This concept study describes the main idea of a low cost, energy harvesting sensor node containing an MEMS accelerometer with frontend, a processing unit, a photovoltaic energy harvesting power supply and a wireless communication link.
