Design concept of motorways & transport corridors in Ukraine

Abstract

The design concept of the new structure of Ukrainian highways in the form of transport corridors with high road and transport potential as elements of the design environment of the state is substantiated. A new approach is applied that allows taking into account the landscape of the area, road architecture, traffic management design and peculiarities of traffic flow conditions. A planning analysis of the road network in terms of linear and quadratic density is presented, the new highway network is built on the basis of the theory of connection graphs. A radical method of increasing the speed of transport, increasing the capacity of the network of streets and roads and ensuring traffic safety is the construction of intersections at the intersections of urban highways at different levels.In the practice of design and construction, transport intersections at two, three, four or more levels are used. Highways or expressways are considered as the total potential of the economy, consisting of the potential of transport routes and roads, infrastructure facilities and the potential of vehicles (car flows, carriage flows). i.e. exergy, a powerful characteristic of the transport corridor, where power is the product of a variable in the cross-section of the path (flow intensity) by a variable in the path space (speed). Of particular importance is the capacity of transport corridors or specific flow intensity, which is the inverse of intensity and characterizes the distribution of intensity along the length of the roadway of highways. The instantaneous load is determined by the flow density. The maximum load of the roadway lane is achieved at the optimal value of the flow speed and the optimal flow density per kilometer of road. An analysis of the distribution of traffic intensity on the German highway as an analog of a transport corridor is made.
