| Summary: | Vehicular-networking-
and especially safety-related wireless vehicular
services have been under intensive research for almost a decade now. Only in
recent years has road weather information also been acknowledged to
play an important role when aiming to reduce traffic accidents and
fatalities via intelligent transport systems (ITSs). Part of the progress can
be seen as a result of the Finnish Meteorological Institute's (FMI) long-term
research work in Sodankylä within the topic, originally started in 2006.

Within multiple research projects, the FMI Arctic Research Centre has been
developing wireless vehicular networking and road weather services, in
co-operation with the FMI meteorological services team in Helsinki. At the
beginning the wireless communication was conducted with traditional Wi-Fi
type local area networking, but during the development the system has
evolved into a hybrid communication system of a combined vehicular ad hoc networking
(VANET) system with special IEEE 802.11p protocol and supporting cellular
networking based on a commercial 3G network, not forgetting support for
Wi-Fi-based devices also. For piloting purposes and further research, we
have established a special combined road weather station (RWS) and roadside
unit (RSU), to interact with vehicles as a service hotspot. In the RWS–RSU we
have chosen to build support to all major approaches, IEEE 802.11,
traditional Wi-Fi and cellular 3G. We employ road weather systems of FMI, along with RWS
and vehicle data gathered from vehicles, in the up-to-date localized weather data delivered
in real time. IEEE 802.11p vehicular networking is supported with Wi-Fi and
3G communications.

This paper briefly introduces the research work related to vehicular networking
and road weather services conducted in Sodankylä, as well as the
research project involved in this work. The current status of
instrumentation, available services and capabilities are presented in order
to formulate a clear general view of the research field. |
