With the continuous advancement of China's Belt and Road Initiative，more and more Chinese enterprises are participating in the construction of engineering projects in Central and Eastern Europe，which brings some challenges for designers to master and use local codes for engineering design and consultation.According to the concrete practice of road reconstruction design of Hungary-Serbia Railway （Serbia section ），the application of horizontal and vertical indexes in road geometric design in Serbian was summarized.It is found that road design in Serbian has perfect design standards and systems.The Serbian code and the Chinese code are relatively close in terms of road geometric design standards，and the specification indexes are more limited than the Chinese ones.Its design theory and system pay more attention to the coordination of route，terrain，and environment.In the design，the consistency and continuity of the line shape are emphasized，with a certain degree of flexibility，leaving sufficient design space for the designer.
