Abstract
"The ecology of the city depends on many factors. Such factors include congestion. Congestion negatively affects the ecological and economic condition of cities and megacities. To solve this problem, a new design was developed to combat congestion – a mobile overpass. The design is used to eliminate traffic jams on the roads. The article describes the structure. The design consists of two main modules. The article discusses the assembly of the structure. The height of the structure allows passenger buses to pass under the structure. The width of one module in one direction is 3.5 m, which ensures the width of the car. The design allows you to increase the intensity of traffic at the intersection during rush hours or during any crowded events. The issues of calculation and construction of a mobile overpass were considered. Finite element and finite difference methods were used to calculate the design. The described theoretical basis of calculations will allow work out various types of mobile overpass constructions which provide their strength, rigidity and stability according to the conditions. From the described theoretical investigations it is possible to construct practical portable car overpasses. The use of a portable road overpass on the city’s road network allows increasing the safety and efficiency of traffic management. "
