The transport system has a direct impact on the economic and socio-economic situation of each country. Planning its development is an important element of policy. Bearing in mind the importance and complexity of this issue, it should be considered using both quanti-tative methods and mathematical models, as well as advanced simulation tools for modelling transport. The article presents a proposal for an approach to simulation tests of the different transport system in the aspect of the emission of harmful exhaust gas compounds from road transport.The tool for analysing and assessing the functioning of e xisting or designed systems is a model in which the properties of the real system, which are important from the point of view of the research objective, should be mapped. The Model of Proecological Transport System (MEST) was presented formally as an ordered four. Also elements of optimization taks shaping of proecological transport system in form of datas, decision variables, conditions and goal function were presented. An example of tests on simulation model was shown.

Sustainable Transport

The unrestrained growth in urbanization and motorization generally contributes to an urban land use and transport system that is socially, economically, and environmentally unsustainable. Urban mobility systems are much diversified in developing countries taking into account their components in terms of transport modes and the development path linked to the urban growth. This paper uses Cotonou as a case study, which is the largest urban and economic city of Benin. The paper first reviews literatures on sustainable transport systems to comprehend the concept of sustainable development and transport. Based on the municipal development plan (MDP) adopted by the local authorities, the paper then evaluates the existing transport policies, projects and infrastructure system, to determine if the current paradigm is moving toward or away from sustainable transport. Furthermore, the principles for sustainable urban transport are developed to see what significance municipal transport policies have given to urban transport from a sustainable transport point of view. Finally some strategies are suggested, adoption of which may lead to a sustainable urban development and transport system in the city of Cotonou.Key words: Sustainable development; urbanization; Bus Rapid Transit; socio-economic; land use and urban transport system.

Transport systems are major emitters of greenhouse gases, which makes environmental sustainability of any transport a crucial issue. Another issue is the lack of a systematic approach to the modeling and implementation of public transport systems. Finally, there are problems with the human interfaces to public transport systems, which do not encourage, and many do not allow, comfortable and simple interaction with the system. In this chapter, the authors discuss their solutions for these problems, explaining how to cover the existing gaps in a methodological and systematic way. The main contribution of this chapter is a model of an on-demand transport system that covers all the points mentioned above and focuses on spatial planning and optimizations including environmental issues in transport planning.

Abstract The problem of ensuring the reliability of heterogeneous transport systems is extremely multifaceted and covers all stages of development - from design to operation. To increase efficiency, there is a need to harmonize the processes taking place in heterogeneous systems within the framework of single transport communication. The lack of appropriate theoretical justification leads in practice to the emergence of insufficiently substantiated decisions, because of which subsequent efforts made to eliminate the discovered shortcomings are, as a rule, costly and ineffective. Assessment of the system of integrated regulation of the transport system, from the point of view of its sustainability, is an indispensable condition for its operational efficiency and reliability. The efficiency of transport processes assumes that the effective functioning of local transport systems is ensured by the level of interaction between participants in the transport process, modes of transport that create positive dynamics of transit freight turnover. The paper substantiates the need for complex interaction in the management of the regional transport system, considering the interaction of adjacent modes of transport in a single information space. The method describes in detail the solution of forecasting and coordination problems in maritime transport systems, harmonization of the interests of heterogeneous transport in solving forecasting and control problems.

Abstract Integrated passenger transport system consists of many factors with various impacts on the entire system quality. In passenger transport, there are mostly individual passengers therefore it is difficult to determine all transport requirements. In the passenger transport system, there are several modes of transport, but passengers mostly use road and rail transport. Passenger transport system is influenced by many qualitative factors with various impacts. The paper is focused on analysis of the role of railways in integrated passenger transport systems. The analysis is from passenger point of view because the key element in railway passenger transport is the passenger (customer), who requires the transport from one place to another. A basic precondition for accomplishing the main requirement (transport), is making the complete offer which provides not only transport, but also other complementary services. There are several types of passenger trains, which jointly create a part of integrated transport system. Quality of this transport system depends on train route topology, timetable of trains, number and location of all stations and stops. Primary function of the transport system is providing transport for passengers on regional, national-interregional and international level; therefore, the analysis involves these levels.

The paper deals with the comparative assessment of competence level of transport system experts. The high level of competence of the experts is the premise to ensure the quality of the expertise of the systems insufficiently formalized from a mathematical point of view and characterized with a high degree of uncertainty. Six factors for assessing the competence of transport system experts were summarized. The values of the priority vector of the competence factors were established with the application of the Saaty algorithm and scale in nine points by the method of comparisons in pairs. The value of the concordance ratio of the experts' opinion for the prioritization matrix was calculated. The comparative competence coefficient of the experts in transport systems was calculated and the hierarchy of experts was established according to the value of the nominal coefficient.

In the article, there is presented the description of the algorithm of the operating process of the simulation model characteristics’ determination realized in the transport system. The simulation model of the means of transport’s operating process has been developed based on the that process’s mathematical model (semi-Markov model). Due of the assumed principles, the constructed model can be applied for the purposes of assessment and control of the operating process because of criterion of different types. Analysis of performance’s assessment of the operating means of transport is one of the ways of the possibilities of correct realization of the assigned transportation tasks in the transport systems. The simulation model of the operating process presented in the work, makes it possible to assess performance of the transport system’s operation from the point of view of the selected assessment criteria: availability of the means of transport and the unit income generated in the process’s modelling conditions. Based on the results of the tests conducted in the real system of the means of transport operating system, the model’s input data have been developed and simulation experiments have been conducted. As an effect, there have been determined the exemplary values of the analyzed characteristics of the transport system’s operation performance analyses.

PurposeSustainable mobility will be the key to the survival of mankind in the 21st century. Cities with debt-ridden and poorly managed transport systems have to change to the ever-growing demands of the public transport system. The low cost of transport has been a key factor in sustainable development for any city. This study is trying to propose a framework for the selection of sustainable transport in context to an Indian case of NCR Delhi, India.Design/methodology/approachThe present study has identified eight criteria for the selection of a sustainable transport system. Criteria for selection of sustainable transport are CO2 emissions, cost of fuel, energy efficiency, cost of maintenance, number of accidents, congestion, number of injuries and road noise. Three alternatives of transport considered for this study are state-run bus, pooled car and Shuttl (App-based buses). The analytic hierarchy process (AHP) is used to prioritize the criteria. The study has further illustrated a framework for the selection of sustainable transport based on these criteria.FindingsIt is observed that CO2 emissions are the most important criterion for a sustainable transport system. It is followed by a reduction in congestion and the number of injuries. Three alternatives of transport considered for this study are state-run bus, pooled car and Shuttl (a service provider). Shuttl has been found to be the most sustainable transport system.Research limitations/implicationsAHP is not able to capture the vagueness in decision-making. Therefore, fuzzy AHP can be considered for further detailed analysis as future scope of study in a different context of a sustainable transportation system. Major implications for policymakers and stakeholders are that development of public transport in cities should be done after considering different dimensions of sustainable operations.Originality/valueThe study has proposed a unique framework for the selection of a sustainable transport system by the public based on sustainability criteria. Findings will help policymakers in formulating strategies for developing sustainable transport system.

The article shows efficient ways of cutting the negative impact of transportation on the environment in metropolises as tools of passing-over to sustainable transportation system. The author identifies key ecological problems in metropolises – consequences of using transport, in particular, CO2 transport emissions are studied in view of their volumes and changes that took place during the last 5 years. It was revealed that all over the world transport damages the environment much more seriously than other industries. The author analyzed advanced methods of passing over from traditional to sustainable transport in different aspects (technical, infrastructural and cultural) in order to protect the environment in metropolises with due regard to economic interests. A lot of obstacles were found, such as time, mode of modern life in metropolises, inter-sectoral nature of transport, etc., which hinder the process of shaping sustainable transport systems in metropolises. As a result of the research the author confirms the necessity to work out a sustainable transport system, in spite of complexity of the process. Apart from that, three variants of shaping sustainable transport system were put forward: basic, standard and advanced.

Using intelligent transport systems in cities is gaining popularity. The fundamental aim of their existence is to improve safety and traffic flow and prevent congestion in city centres. All people moving around the city, such as public transport passengers, as well as truck and emergency vehicle drivers and drivers of passenger vehicles, are users of intelligent transport systems. Research which was carried out for the article entirely concerns functioning and utility of intelligent transport systems from truck drivers’ experience. The main aim of the research was to evaluate services and tools within intelligent transport systems in European cities which are visited by Polish truck drivers. Our research indicates that most drivers (almost 98%) stated that they find intelligent transport systems useful and 92.5% of interviewed pointed that intelligent transport systems help with their everyday work duties. Of all the tools in the survey drivers agreed that variable content signs, accommodative traffic lights, and extra road illumination have most influence in road safety. Identifying the most useful and helpful tools of intelligent transport systems will allow to define their preferred development directions from truck drivers’ point of view.

Today, the design and remodeling of urban environments is being sought in order to achieve green, healthy, and sustainable cities. The effect of air pollution in cities due to vehicle combustion gases is an important part of the problem. Due to the indirect effect caused by the Covid-19 pandemic, political powers in Europe have imposed confinement measures for citizens by imposing movement restrictions in large cities. This indirect measure has given us a laboratory to show how the reduction in vehicle circulation affects in a short time the levels of air pollution in cities. Therefore, this article analyzes the effect in different European cities such as Milan, Prague, Madrid, Paris, and London. These cities have been chosen due to their large amount of daily road traffic that generates high levels of pollution; therefore, it can clearly show the fall in these pollutants in the air in the analyzed period. The results shown through this study indicate that the reduction in combustion vehicles greatly affects the levels of pollution in different cities. In these periods of confinement, there was an improvement in air quality where pollutant values dropped to 80% compared to the previous year. This should serve to raise awareness among citizens and political powers to adopt measures that induce sustainable transport systems.
