    Opis:
    The development of industrialization in the 20th century that resulted in the conversion of agricultural land in the industrial societies and migration of rural population to urban areas, started the process of urbanization in the world. The changes resulted in infrastructure transformations and determined the shape and functioning of the centers of modern life. Present continually increasing urban growth, complicates the free movement of goods and cargo flows in cities. It affects their dysfunctional nature, generating phenomenon in the form of transport congestion. The aim of research is the approximation of this problem. The study will be done on the example of the transportation system condition in the urban area of Białystok.

    Opis:
    The objective of this paper is to discuss the replication of passenger congestion (overcrowding) effects on output path choices in public transport assignment models. Based on a comprehensive literature review, the impact of passenger overcrowding effects was summarised in 3 main categories: the inclusion of physical capacity constraints (limits); the feedback effect between transport demand and supply performance; and the feedback effect on travel cost (discomfort penalty). Further on, sample case studies are presented, which prove that the inclusion of capacity constraints might significantly influence the assignment output and overall results in public transport projects’ assessment – yet most state-of-the-practice assignment models would either miss or neglect these overcrowding-induced phenomena. In a classical 4-step demand model, their impact on passengers’ travelling strategies is often limited to path (route) choice stage, while in reality they also have far-reaching implications for modal choices, temporal choices and long-term demand adaptation processes. This notion has been investigated in numerous research works, leading to different assignment approaches to account for impact of public transport capacity constraints – a simplified, implicit approach (implemented in macroscopic-based models, e.g. PTV VISUM), and a more complex, explicit approach (incorporated in mesoscopic-based models, e.g. BusMezzo). In the simulation part of this paper, sample tests performed on a small-scale network aim to provide a general comparison between these two approaches and arising differences in the assignment output. The implicit approach reveals some differences in assignment output once network capacity constraints are accounted for – though in a simplified manner, and producing somewhat ambiguous output (e.g. in higher congestion scenarios). The explicit approach provides a more accurate representation of overcrowding-induced phenomena - especially the evolving demand-supply interactions in the event of arising congestion in the public transport network. Further studies should involve tests on a city-scale, multimodal transport model, as well as empirical model validation, in order to fully assess the effectiveness of these distinct assignment approaches.

    The economic development of Poland depends on a modern, effective and safe transport system. It is dependent on proper legal regulations both Polish and EU. They give an opportunity to develop innovative urban logistics or electromobility. The aim of the article is to analyze EU and Polish legal regulations regarding innovative public transport, as well as to present development prospects for electromobility.
    Rozwój gospodarczy Polski zależy od nowoczesnego, efektywnego i bezpiecznego systemu transportu. Uzależniony on jest od właściwych regulacji prawnych zarówno polskich, jak i unijnych. Dają one szansę na rozwój innowacyjnej logistyki miejskiej czy elektromobilności. Celem artykułu jest analiza unijnych i polskich regulacji prawnych dotyczących innowacyjnego transportu publicznego, a także przedstawienie perspektyw rozwojowych elektromobilności.

    Opis:
    Transport is among the key sectors that play crucial roles in the effort to achieve sustainable economic growth and poverty reduction thereby bringing about sustainable development in Africa. By 2010, traffic accidents in Africa will kill almost the same number of people annually as now die from HIV/AIDS in East and Southern Africa combined. And, for every 20 Africans who die in 2010, one will be killed in a traffic accident. Intelligent Transport Systems play an important role in shaping the future ways of mobility and the transport sector. It is expected that through the use of ITS applications (Telematics), transport will become more efficient, safer and greener. The huge potentials and benefits, however, can only be reaped if ITS solutions are put in place and be well managed. By investing now in reducing the number of traffic accidents, Africa can save millions of lives over the coming decades and reap significant economic and social benefits.

    Opis:
    Prioritizing the development of public transit and enhancing its attractiveness is an important way to solve the problem of urban traffic congestion and achieve sustainable development. To improve the service quality and overall operational efficiency of urban public transit, an evaluation index system related to the comprehensive experience of passengers, service supply quality of public transit enterprises, and supervision of management departments was introduced from both the demand and the supply of public transit travel services. Based on the data distribution characteristics of the boxplot in statistics, the evaluation level and corresponding value range of each index were determined, and the comprehensive weight of the index was determined using the linear weighting method combining the analytic hierarchy process and the entropy weight method, so as to reduce the influence of single weighting method on the evaluation results of comprehensive service quality of public transit. An evaluation method of public transit comprehensive service quality based on the extension cloud model was established. The evaluation results of the model were obtained by calculating the cloud affiliation and comprehensive certainty, and a reliability factor was used to test the evaluation results, which solved the problem of randomness and fuzziness in the process of comprehensive service quality evaluation of public transportation and made the evaluation results closer to the reality. Finally, the established comprehensive evaluation model was applied to a city for example analysis, and the corresponding evaluation level was obtained as good. The value of the reliability factor in the model was less than 0.01, indicating that the model has good applicability and a certain application value for the comprehensive service quality evaluation of public transit. The evaluation method fully considered a variety of evaluation indicators, specified the evaluation level of comprehensive service quality of public transit, and the evaluation results provide a theoretical basis for public transport enterprise to make targeted improvement measures.
