Selecting An Optimal Traffic System For Cities

Due to rapid development of cities, the existing transportation systems very often cannot satisfy the traffic demand. In these conditions it is necessary to reconstruct the existing and construct new transportation facilities. As investment in the transportation system is often greater than possibilities, it is very important to decide reach rational decisions. Hence the investment policy must be rational and there is a simple rule: investment should be compensated as soon as possible by savings in the exploitation, The main prerequisite for successful management of the transportation strategy is good knowledge of the interaction between national economy, intensity of perspective transportation work, capacity and investment, This paper presents a methodology for determining the most convenient model of the whole transportation system or part of the system. The methodology is based on the assumptions that the program of investment in the planned period must be done so that the realized investment and resulting costs of exploitation give a minimal discount investment. The methodology is based on the application of the method of discount investment i.e. there is a correlation between the rate of flow, capacity, stage investment and the exploitation of costs in the depending on time. Accordingly, time-dependent investment interaction, in its application, manifests a real economic category. Due to this methodology the transportation policy has a significant tool which can show: when, where and how much to invest and finally the expected benefits.
