Abstract
The problems of the transportation system issues arising from reduced capacity of the street and road network and increased traffic delays during utility and maintenance works are considered. International experience in reducing transport losses is analyzed, including temporary detour roads, intelligent traffic management systems, and modular bridges. Special attention is given to mobile road crossings as a promising solution that ensures traffic flow without complete road closure. The technical limitations of existing engineering solutions are identified, and an algorithm for selecting and designing mobile road crossings is proposed. The algorithm includes load determination, strength verification, and the possibility of adjusting structural parameters when necessary. The research results provide a basis for developing a methodology for designing mobile road crossings adapted to the conditions of Kazakhstan’s transport infrastructure.
