Abstract

Cooperative systems which rely on vehicle-to-infrastructure communications are designed to tackle important road"br" transport issues, such as safety and pollution. Since the associated monetary commitment is substantial, a clear"br" understanding of the appropriate business models and likely costs, impacts and benefits is necessary before"br" investment decisions can be made. A tool for estimating the costs and benefits, from both business and the societal"br" point of view, was developed in the COBRA+ project, to assist National Road Authorities (NRA) during their"br" decision processes. This paper illustrates the application of the tool to use cases in Austria, England and the"br" Netherlands. The study identifies some of the key aspects to focus on in order to achieve a beneficial balance"br" between costs and positive impacts. Findings reveal that the costs are likely to be higher than the monetised benefits"br" over the time period investigated (to 2030). The financial role of the NRA (or their Road Operator) is particularly"br" influential for the business case.
