During last few years considerable activities on developing city transportation system have been initiated in Belgrade, capital of Serbia These activities are related to reconstruction and revitalization of the existing elements of traffic infrastructure, as well as to preparation of the study, planning and design documentation for investments into further development of the transport system. For the purpose of establishing optimal development of the transport system in Belgrade, it was necessary, using existing resources, to create a modern transport model as a tool for the optimisation of Belgrade transport system development. City Council of Belgrade financed the Belgrade Transport Model (BeTraMod). It was a first experience after many years of city government of Belgrade in developing huge data basis about transport system using modern software package (Vissum). Transport Model implies a set of relevant data (numeric, graphic and other), indicators, parameters and simulation models, expressed in space and time, in such way that: characteristics and behaviour of transport system in the past can be reconstructed; -certain regularities in transport demands and transport supply, on one hand, and socio-economic and land use parameters, on the other hand, can be established; present state of transport system can be presented and evaluated; future functioning of transport system, or its parts, can be evaluated, forecasted or designed; specific, existing states or states defined by development scenarios can be evaluated using Transport Model elements. Once established, a Transport Model is open for additions and upgrading that may comprise all elements or parts of integral elements, with innovated or altered data, indicators, parameters and simulation models. Therefore, it can be said that Transport Model is developing concurrently with transport system, i.e., more broadly speaking, and parallel with the city planning system. Transport model is used as official planning-design basis for elaboration of:t system of specific inner zone in relation to the purpose of this transport model formation, that are aimed at development planning and programming, selection of strategies and/or tactics, etc., of the zones they are prepared for; studies/analyses/expertise being prepared for specific components of transport system (modes and/or infrastructure), aimed at planning and research of development, selection of strategies and/or tactics etc., of the selected component;n urban networks, studies/plans of locations allotted for construction of apartments, commercial, service, industrial, storage, trans-shipment and similar facilities, traffic structures and areas, or facilities in which said use is partially represented; analyses of public transport, general and draft designs of infrastructure and transport structures; and pre- feasibility and feasibility studies of infrastructure and traffic structures. In view of general application value of the Transport Model, it is obvious that concept of the user of Transport Model has broader meaning. In this case, having in mind the basic purpose of creating Transport Model, application value is oriented to users mainly in the scope of planning, programming, management and development of transport system. Data, indicators, parameters and formulations of simulation models derive from/are made on the basis of official government data sources (land registry office/cadastre, government land surveying, statistics, internal revenue service, etc), from other sources (plans, analyses, studies, expertise), and from sources from continuous and/or occasional research carried out by institutions, organizations, organs and other entities. Since BeTraMod is created it was already used for project documentation of three projects: pre-feasibility study and general project of Inner-city Ring Road, pre-feasibility study and general project of Light Rail Transport and feasibility study of Bypass road of Belgrade. The paper will present Procedure for building Model as a tool Possibilities and constraints of Model Experience in application Further improvements in model Conclusions.
