The processes of formation of services of intelligent transport systems (ITS) imply certain evolutionary stages in the field of traffic management (ODD). Qualitative evolution consists in the transition to dynamic design. At the moment, the digital double of ASUDD is functioning. In the field of traffic light control, the concept of a digital twin allows you to adjust the operation of traffic light objects in real time, finding effective solutions to transport problems. The next step in the evolution of the ODD is a bank of typical scenarios, which will allow you to choose the most approximate with subsequent adjustment. One of these scenarios is the transition to band-by-band management. The Service Lane tool will allow road users on public roads to receive priority. As a result, the effective functioning of the transport and road complex will be implemented by ensuring the required mobility of the population.

The shear punching of the reinforced concrete slabs is a complex process occurring when considerable force is concentrated on the relatively small area of a column-slab connection. An incorrect assessment of load capacity of slab under the punching shear may lead to an accident. One of the most significant factors affecting the slab capacity is longitudinal reinforcement. In this article much attention is given to the analysis of the longitudinal rebar impact on the maximum loading capacity of reinforced concrete slabs without transverse reinforcement affected by punching shear force using the finite element method. The results obtained via the finite element simulation are compared with laboratory tests and manual calculations carried-out using various methods represented in different national building Codes of practice.
