Problem of modern transport systems and its structural elements

Modern large cities and megalopolises are constantly facing transport problems that require finding the right, automatized solutions. Difficulties connected to the admission of high-intensity traffic flows increase through a large number of pedestrian flows. Increasing the number of individual cars and changing the structure of the city causes on top environmental problems and problems of road condition and quality.

The main instrument of traffic management is colour light signaling, designed for the first pass of road users through a certain section of the UDM, and also for determination unsafe sections of streets (roads). The structure of modern automatized traffic management systems (ASM-T) is built on the hierarchical principle of information processing, which while identifying the total management system should operate, foresees the allocation of several mutually subordinate management levels: local, zonal, district, citywide.

Transport models based on modern information technologies are powerful computational software complexes that, based on the functional and spatial characteristics of a city, together with all existing data, calculate the most likely distribution of transport and passenger flows by of the street-road network (UDM).

Effective resolution of transport network problems is to be solved with the help of geo-information analysis and geo-information modeling, namely through building a transport model of the city with the help of geo-information systems.
