A large part of these roads do not have sufficient pavement width. The 396 km-long HNC road network consists of 13 roads that are either graveled or paved. The HDM-4 study was performed with the aim to define road works program and investment priorities by analyzing impacts of different budgets on future network condition. The paper describes the application of HDM-4 model for local roads in Bosnia and Herzegovina (BiH), in the Herzegovina-Neretva Canton (HNC). The World Bank Highway Development and Management (HDM-4) tool has been used extensively for the management of road networks, particularly in developing countries.
