Abstract
Through communication between vehicles and
infrastructure, vehicles can receive real-time warnings
on incidents and dangerous situations, and can send own
sensor data and observed incident information to other
road users. Information between vehicles and
infrastructures can be exchanged either using ITS-G5 or
cellular communications. This paper describes how a fog
vision sensor has been developed and deployed for warning
drivers about adverse road weather conditions. A
hardware-in-the-loop driving simulator has been utilized
to test the transmission of vehicle data. Performance
measurements of the communication between vehicles and
infrastructure have been made for both ITS-G5 and LTE.
LTE and the future 5G will provide lower latency, and
hence may become the preferred solution especially for
road side unit to vehicle communications. Providing
seamless connectivity between different network
technologies, a mobile IP based solution is utilized with
Quality-of-Service (QoS) assisted handovers. Real-time
QoS measurements with fast handovers enable the system to
react rapidly to changing circumstances. Our solution can
exploit multiple networks and prioritize them by
quantities such as preference, signal strength and
geotagged formerly measured link quality.
