Planning of urban spaces and mobility has become a demanding task. All modes of transport have to be granted their very own right of way. Stakeholders of particular modes, tourists and commuters, old and young have their own needs and ideas and they all demand to be involved in the planning process of transport projects without having to dig into the words and numbers produced by traffic engineers. Microsimulation is a tool which accommodates both: the requirements that are set by the complexity of such projects, as well as the needs to produce easy-to-understand information and communication material. This paper demonstrates the capability of microsimulation through a French case study, including the planning and design of transport schemes for a busy city centre and urban area where all modes of transport are being used and there is a strong focus of public attention.
