The complex analysis of traffic system safety in Nigeria based on qualitative and simulation modeling was performed. These models allow us to perform a preliminary assessment of measures aimed at safety improvement of the traffic system situation in Nigeria, and to make projections to improve the parameters of the transport system. In this paper, the results of the system analysis of the transport network safety in Nigeria based on qualitative and simulation modeling are presented. The qualitative model of transport network safety and the model of system dynamics is developed, the safety measures based on simulation are suggested. The obtained results could be used for support of decision making in the field of transport network management in Nigeria. The experiments were conducted on qualitative models, they showed the effect on the transport system parameters of such measures: increasing fines for violations of the road regulations and increasing of the funding of the road repairing and construction. The support organization in decision-making in the management of the urban transport system development is very important. This problem can be solved with the use of different approaches. The use of qualitative and dynamic-system modeling for complex analysis of the transport system and evaluation of measures effectiveness aimed at improving its safety is proposed in this paper.

The transport system plays an important role in human activities and is an integral part of the successful functioning of the urbanized area. The increasing degree of provision of urban residents with transport services should at the same time keep the environment environmentally friendly and sustainable over time. The article is devoted to the issues of ensuring the rational functioning of the city transport system based on the development and implementation of an intelligent road infrastructure management system, the intellectual core of which are simulation models of problem areas of the road network. The objective of the study is the development of tools for organizing traffic in the conditions of the rapid growth of the fleet of vehicles. Research tasks were to analyze the research in the field of traffic management, to consider methods to reduce and prevent traffic jams on roads in general and in individual sections in particular. The following research methods were used: methods of system analysis, methods of modeling traffic flows, simulation, computer experiment. Achievements: the developed simulation model can be used to conduct a computer experiment in order to select the optimal parameters for the functioning of traffic lights on a specific section of the road network of the city of Naberezhnye Chelny

Introduction. The experience of developing the economies of the developed countries of the world suggests that it is directly related to the evolution of transport and infrastructure. In most of countries, intelligent transport systems (ITS) are under investigation as one of the scientific directions of the symbiosis of the economy - technology – telematics, and considered as the most effective tool for solving transport problems. The efforts of international organizations, state representatives in the field of transport, scientists, entrepreneurs and the public are aimed at such key areas as: significant increase in both the safety of transport on all modes of transport and capacity grows of the transport system of the country. Purpose. The goal of the article is to develop a single integrated approach to the definition of the term ITS and to provide a general classification system with details on the management objects. Methods. To achieve the goal methods have been used based on the systems approach, management theory and decision-making theory. The system analysis has been used to determine the scientific task. Results. In order to implement the tasks of transport management in terms of ITS, the system analysis of the field of research has been carried out in the article, including the systematization of the definition and the construction of a general classification system with details on the management objects. The analysis of the subject area of ITS usage has allowed establishing the main classes of the analyzed objects, to classify the tasks of monitoring characteristics, organization of management of transport flows and transportation process, information support for participants, organization of transport infrastructure management. Research of the literature sources allowed to form an integrated approach to the ITS classification system, which includes both systems introduced in the objects of transport infrastructure and in the management of transport flows. In the addition to the above, the main thing in the infrastructure objects is the terminal monitoring and management system, as well as the security management system. Conclusion. ITS is a new type of transport management systems that are gradually replaced by automated control systems. They are focused on modeling various cases and forecasting of dangerous situations and be used for decision-making tool in the condition of great complexity and large amounts of data. ITC can be considered as an important component of the modern integrated approach to improving the efficiency of the functioning of the country's transport system by expanding their information infrastructure: automated data collection on state of the system in real time, modeling direct and indirect operational impact on the formation and change of transport flows.

The paper presents results from simulation analysis of the western 3rd ring road project in the city of Krakow (i.e. Trasa Lagiewnicka, Trasa Pychowicka and Trasa Zwierzyniecka), performed in the macroscopic model of transport system in the Krakow metropolitan area. Simulation works reveal shifts in traffic flows and changes in urban transport network performance which would likely take place after the stage-wise construction of consecutive 3rd ring road western sections. Results indicate that the analysed road schemes would indeed have a relevant impact upon travel conditions, though in initial stages these would be rather limited and confined to the southern part of the city. Therefore, completion of the whole western section of the 3rd ring road is crucial to its overall effectiveness and would only then bring substantial benefits on a city-wide scale. Simulation works seem to confirm that the future 3rd ring road would become an essential and highly-utilised link in the urban road network and would provide a much more efficient connection between the northern and southern parts of the Krakow city. However, apart from the projected benefits, it is also important to underline potential negative implications – and consequently, further changes in city transport system should envisage reduction of the road network capacity within the inner-city area. This would then provide the best possible chance of fostering the improvements achieved with the 3rd ring road scheme: i.e., positive changes in accessibility and travelling conditions across the whole city and long-term, sustainable traffic congestion relief in the inner-city Krakow area.

The paper describes the assessment of 3 Vilnius city development scenarios according to transport system parameters multi‐criteria analysis and performing transport system modelling for 2015 and 2025 years. Vilnius city development scenarios such as concentrated development, extensive development and decentralized concentrated development have been evaluated from a transport viewpoint. Vilnius city development scenarios have been evaluated by using SAW (Simple Additive Weighting) multi‐criteria method. According to this method development scenarios ranking calculations have been performed using transport system indicators. Urban transport system analysis model was developed for Vilnius conditions, which estimates the fuel consumption, average travel distance and driven time by car in morning peak hours depending on urban areas development scenario and socio‐economic data. This model should be used when calculating new projects of the transport infrastructure (by‐passes, new bridges) and when evaluating the economic efficiency of traffic organization projects. Santrauka Straipsnyje analizuojami trys susisiekimo sistemos požiūriu Vilniaus miesto plėtros scenarijai. Miesto plėtros scenarijai, kaip sutelktoji plėtra, decentralizuotai sutelktoji plėtra ir ekstensyvioji plėtra, vertinami daugiakriteriu metodu SAW ir atliekant Vilniaus miesto plėtros scenarijų modeliavimą 2015 m. ir 2025 m. Daugiakriteriu metodu nustatoma plėtros scenarijų prioritetinė eilė, vertinant Vilniaus miesto susisiekimo sistemos rodiklius. Modeliuojant plėtros scenarijų, nustatomi tokie rytinio piko metu rodikliai: kuro naudojimas, suminis nuvažiuotas atstumas, suminis kelionės laikas. Modeliavimas remiasi esamais ir numatytais bendrojo Vilniaus plano miesto gatvių tinklo duomenimis, transportinių rajonų dabartiniais ir prognozuojamais socialiniais bei ekonominiais duomenimis. Sukurtas modelis gali būti sėkmingai naudojamas vertinant transporto infrastruktūros ir eismo organizavimo projektų įtaką miesto susisiekimo sistemai.

Multiple actors from both private and public sectors are currently involved in the design and operation of urban passenger transport systems seeking at optimizing their own objectives. Multi-criteria decision-making (MCDM) techniques actually aid this process. In this chapter, the authors consider the problem of locating multimodal terminals of an integrated public passenger transport system (IPPTS). A case study for the city of Bogota, Colombia is evaluated. Majority of works in MCDM does not explicitly justify the choice of the applied technique. This chapter applies three different techniques, AHP (analytic hierarchy technique), ELECTRE II (elimination and choice expressing the reality), and CRITIC (criteria importance through intercriteria correlation), to solve problem. A feature of this study is that traditional economic and logistic criteria are evaluated together with environmental and social criteria not previously evaluated in the literature. Numerical results show that each multi-criteria approach may prefer a different alternative, depending on the intrinsic behavior of each technique.
