As conclusion in the previous reports of the working groups, the major complications in the operation of an urban road tunnel are connected with the large traffic volume and specific traffic characteristics. Urban traffic poses high demands for the management of traffic, incidents and maintenance, not only for the tunnel but also on the surrounding network. As an important infrastructure in the urban area in terms of economy and mobility there is a constant pressure to reduce the duration of closure of urban tunnels.
