Cooperataive Road Sign and Traffic Light Using Near Infrared Identification and Zigbee Snardust Technologies

摘要

Vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I as well as I2V) applications are developing very fast. They rely on telecommunication and localization technologies to detect, identify and geo-localize the sources of information, be them vehicles, roadside objects, or pedestrians. This paper presents an original approach on how two different technologies (a near infrared identification sensor and a Zigbee smartdust sensor) can work together in order to create an improved system. After an introduction of these two sensors, two concrete applications will be presented: a road sign detection application and a cooperative traffic light application. These applications show how the coupling of the two sensors enables robust detection and how they complement each other to add dynamic information to road-side objects.
