Decision-making to improve the functioning of route systems is an extremely necessary, but at the same time difficult task, as it determines the overall socio-economic development of the city, the stability and safety of its transport complex. The purpose of this work is to establish patterns of formation and distribution of passenger flows for the transport network of the city with a description of models of their operation. The traditional approach to determining the concentration of travel is described by "synthetic" models, such as gravity. A practical solution to the problems of transport planning is the modeling of behavioral demand, which is based on the concept of attractiveness function. The load of the transport network is determined by the number of vehicles on it. Download simulation is the distribution of inter-district correspondence along specific paths connecting district pairs. In normative models, the distribution of traffic flows is based on the optimization of some global criterion that characterizes the efficiency of the entire network. The descriptive approach is based on the principle according to which each participant seeks to minimize their own costs. The most effective is the model of finding the equilibrium distribution. One of the variants of which is used to distribute users of one class. In this way, the location of transport interchanges in the transport infrastructure of the city mainly determines their transport structure. The distribution of passenger correspondence between interacting infrastructure objects is described by a gravitational model. The equilibrium distribution search model should be used as a task to optimize the distribution of traffic flows.

Original Edition

St. Petersburg is the fourth most populous city in Europe (after Moscow, Greater London and Greater Paris). Hundreds of thousands of people move daily within the urban agglomeration. Under these conditions, the effective functioning of the urban economy is impossible without a modern transport system capable of providing a solution to current and future problems of the urban economy. The work aims to analyse the effectiveness of the development of the transport system of St. Petersburg. Therefore, it is necessary to examine the main provisions of the most critical regulatory legal acts regulating the city's transport system's development, identify their advantages and disadvantages, and determine how effectively the activities outlined in them are being implemented in dynamics. The author's analysis of the two editions of the St. Petersburg transport system development program (the original edition of 2014 and the current edition of 2020) revealed negative trends, consisting of the deviation of the program indicators' actual value their planned values. Based on the results of the study, the author draws the following conclusions: when implementing the program for the development of the transport system of St. Petersburg, general principles of strategic management are not used, particularly, the effectiveness of program measures is not analysed, the reasons and factors that led to the deviation of planned indicators from the actual ones are not extended for a new period without any assessment of the results achieved; indicators of the transport system development program are constantly being adjusted downward; There is no unified management system for the development of transport infrastructure in the city, the program activities themselves are distributed among separate committees of the city administration, which harms the results of socio-economic development of the transport complex.

The article presents a forecast of changes in the level of transport accessibility and mobility in Poland as a result of the anticipated development of the network of expressways and motorways. The progress which has been made in this respect in the last few years in Poland is unquestionable and unrepeatable by any other European country. Will the subsequent investment plans concerning the road network of the highest parameters offer equally impressive results as far as the increase in Poland’s territorial cohesion is concerned? The aim of this article is to establish in what way the planned infrastructure investments will affect the changes in transport accessibility and mobility as well as whether they will result in the changes in traffic flows directed to Warsaw and other regional centres. To achieve this, an analysis of the present and target state of the road network in Poland was conducted from the perspective of changes in accessibility, anticipated traffic flows, and mobility. For this purpose the authors used the analyses of isochrone and accumulative accessibility in ArcMap environment and research into traffic flows and their changes in the Visum software. The conducted research showed that the planned transport network might result in induced traffic through a increase in accessibility (the central variant) with the assumption that an increase in mobility would be vented in the real face of the phenomenon of motility. The fact of opening new road sections of expressways will contribute to substantial changes in the directions of traffic flows only to a slight extent, and the only transformations concern regions with already developed fast car transport infrastructure whose functionality is limited due to the lack of its cohesion in the subsequent course or lack of a developed network of expressways and motorways.

The transport network of cities can be represented as a complex of streets and passages, as well as elements of public transport infrastructure unconnected with the street and road network. It is reasonable to represent the real network in the form of a simplified network based on graph theory to analyze the properties of the transport network. There are various methods of network connectivity assessment, including those based on various indices. According to all indicators in the street and road network of the city of Petrozavodsk it is necessary to increase the number of units. The implementation of recommendations for changes of the street and road network of the city of Petrozavodsk will reduce traffic congestion, the number of accidents and transport expenses. It is recommended to use the proposed method to assess and improve the street and road network of cities.

The article discusses the problems of using data mining in a transport model as a digital platform for analysing data on traffic flows in a megapolis, and prerequisites for creation in future of single data banks and an integrated environment for interaction of models of different levels as clusters of the digital economy, which will consider all modes of transport to assess transport demand and develop projects for organizing traffic in a megapolis.The objective of the work is to study the processes of obtaining quantitative characteristics of objects of transport modelling when creating a single electronic environment by calculating the derived parameters of the transport network of a megapolis. Quantitative spatial characteristics of an object are associated with calculating the distance from a city centre and a main street and are determined using geographic information systems entailing consequent problem of data unification and efficient data storage.As part of achieving that objective, it is shown that it is necessary to create a preprocessing and validation procedure for all primary transport data, since data sources have different formats and spatial interpolation of tracking data. For this, it is recommended to use various methods of data analysis based on GIS technologies, digital terrain modelling, topology of the road network and other objects of the transport network of a megapolis. Besides, the use of intelligent data should be preceded by formatting and grouping the source data in real time. The most common errors arise at the stage of the iterative process for obtaining quantitative characteristics of objects of transport modelling and building the optimal route in terms of travel time along a certain transport network.The existing trends of urban growth require global digitalization of all transport infrastructure objects, considering changes in the functions of the transport environment and in intensity of traffic flows. Theis entails further development and implementation of new information technologies for data processing using neural networks and other digital technologies.

Projecting of urban transport infrastructure, which forms a comfortable habitat and development of territories, is impossible without forecasting the parameters of transport and passenger flows. These parameters are formed under the influence of the subjective choice of urban residents on the routes along the road and route network. The study aims to identify factors affecting the distribution of transport and passenger flows through the existing urban transport network. It is revealed that the gravity function of employees of city-forming enterprises, which determines the emergence and absorption of transport and passenger flows of the city districts, can be described by parameters of urban structure, socio-economic factors and parameters that characterize zones of residence and main area of employment. The developed model was tested on real data from Kharkov - the second largest city in Ukraine.

The concept of rationalization can be defined as a structured process to increase effectiveness through a maximize use of existing resources. Rationalization in terms of road infrastructure or systems can be achieved in various ways; establishing hierarchy of routes, optimize bus-stop points with density distribution changes, proper integration of motorized and non-motorized transport and providing policy framework. In the highly densely populated city of Dhaka, rationalizing public transport is one way to minimize the mismatch between demand and supply. This paper is concerned with the following issues: providing a general description of the city transport system, identifying problems and demands analysis in the area of study area; studying the rationalization of  public transport, particularly public transport system design (routes and their categorization) and proposing the creation of a multimodal hierarchical transport network for Dhaka. The findings suggest establishing a major component, a hierarchal-network. Beside establishing network hierarchy, rationalizing is also interdependent upon system planning, institutional framework, organization and financing, terminal locations, public-private relationships, government roles, policies, service integration, and the management of public transport. This is can be accomplished by all stakeholders sharing the relative success and failure, depending different levels of each components’ performances. The findings of this paper will help planners and decision makers to optimize the investment in the transport infrastructure.
