Effects of improved management of traffic flows on sustainable road safety

Knowledge of the improved management of traffic flows and its effect on road safety is an important component in the process of sustainable road network development. Having in mind the fact that so many road traffic casualties occur, a key priority in European Transport Policy is making Europe’s highways as safe as possible. The mentioned objective is attained by means of sustainable safety. The various traffic models, developed on the base of the characteristics of different road users and their often conflicting requirements, have a vital role in the mentioned process. This paper investigates the applicability of existing traffic flow models in the efforts to achieve sustainable safe road traffic. This characteristic is limited, because these models are based, primarily, on traffic conditions of cars or motorized vehicles of similar characteristics. The aim of the paper is to contribute to sustainable safe road traffic, emphasizing the need to develop the models which must be taken into account of the users of different transport modes having conflicting requirements.
