Sustainable transportation modelling – case study of Belgrade
ABSTRACT
Sustainability is not about threat analysis; sustainability is about systems analysis. Principles of sustainable transportation planning have been identified and recognized in developed countries. Transport solutions that are efficient and provide positive economic, environmental and social effects are the ones needed. Solutions that best fit gain advantage over ones that simply solve the problem.
In countries in transition, the side effects following the solution of the traffic problem are often not considered. It is absurd not to accept the experiences of developed countries. The use of simulation (both macro and micro) is common in solving different problems providing benefits in all fields of influence. Sustainable transport and mobility management strategies could easily be simulated. The changes in the street network exploitation characteristics change the conditions in the traffic flow. As a consequence, environmental parameters are also modified. The quantification of different outputs gives a valid basis for further analysis of the effects caused by proposed measures.
In the transportation modelling it is necessary to apply well known and tested procedures combined into the specific methodological unit that would provide testing solutions of great social importance to the functional, economic and ecological standpoint.
The aim of promoting this approach in developing countries is to avoid potential negative effects that arise in other fields besides those in the focus of the problem. First of all it is about environmental effects and strategic approach in traffic infrastructure development and management in countries in transition. In this way, a complete picture can be created and parameters which should help in the process of decision making and management in the transport system can be defined. The final goal is the efficient and cheaper process of transportation planning and solution evaluation in order to achieve efficient use of present transportation infrastructure.
This approach was tested in the Case Study of Belgrade, Serbia, in 2007 and the results will be presented in the paper. The solutions are consistent with the sustainable transport concept. Case Study hypotheses and solution scenarios came as a result of expert experience according to infrastructure capabilities.
