ABSTRACT
The Croatian Ministry of Maritime Affairs, Transport and Infrastructure commissioned the development of the National Transport Model, including collection of all available data, carrying out necessary surveys, developing networks models and demand models for freight and passenger demand for the base year, calibrating and validating the models, and developing forecast models. Model has 985 internal and 267 external transport zones and over 360.000 km of modelled links. The purpose is to identify shortcomings, bottlenecks and issues in the current and the planned future transport systems. The model is used to identify specific measures and projects for the different transport modes and their integration supporting the selected strategies. The model produces quantitative results allowing to determine impacts of the strategy alternatives and of the measures on traffic conditions, on social and environmental impacts. The availability of a National Model guarantees that similar approaches are used at the regional level, improving the general transport planning approaches all over the country.
