Abstract

A methodology is reported for urban road network design in order to improve the level of network service and the safety. It is oriented towards reorganising the network configuration for an exogenous flow disturbance. Endogenous causes occur when several vehicles are reciprocally conditioned; exogenous causes depend on factors which are external to the flow. The procedure contributes to solving the network design problem by simulation and multicriteria analysis. In this work the procedure is oriented to solving the problem by considering the demand variation during the day with a Deterministic User Equilibrium approach for the assignment in each time slice in which the optimum junction signal setting is carried out. The design considers different indicators relative to users and to the general public: an indicator is introduced relative to the network hierarchy. A numerical application was carried out on a real road urban network and useful general indications were obtained about optimal design configurations. It was noted that, by appropriately organising link directions in the network area around the disturbance, safety levels may be increased. For the covering abstract see ITRD E116488.
