Abstract
Intelligent Transport Systems realize safer driving which is considered by road state information from multiple types of onboard or roadside sensors. Autonomous driving vehicle essentially requires to collect and process own sensor output and operate autonomously. When onboard system processes sensor output for onboard decision of road conditions at the position, it is necessary to consider how the vehicle exchange road information with other vehicle or roadside unit. This paper introduces cognitive wireless communication method which is designed for exchanging of road sensing information. Our proposal system consists of 920 MHz, 2.4 GHz and 5.6 GHz band wireless communication links and dynamically selects the best link based on wireless status. We evaluate network performance in-the-field experiments for V2R communication. From the result, our design could perform several times of higher efficiency for data delivering which is compared with the similar approach based on 2.4 GHz WLAN.
