The communication to enable the services of intelligent transport systems (ETSI ITS G5) is based on the inter-connection of vehicle on-board units (OBUs) by vehicle ad-hoc networks on the one hand, and has access the service infrastructure through the on-board units and the networked devices (RSUs) installed along the roads, on the other hand.

My task was to provide a summary overview and assessment of the basic architectural and topological versions of the RSU backhaul access network, as well as the specification of a simple process, methodology and models to support the design of these networks that meet the requirements.

When developing the design process, models and methods, I started out from the communication needs and requirements of the typical service portfolios (e.g. C-Roads Day-1-Services) to identify the communication needs and requirements of the services of intelligent transport systems, and to specify the data requirements and expected results of each design step.

Based on the communication needs and requirements of the services and the characteristics of the motorway environment, I developed basic architectural, topological and technological case to support the fault tolerance of ITS services.

The practical applicability of the developed models and methods was illustrated by examples based on models of the FLEXPLANET network modeling system.
