Opis:
This paper presents actual public transport problems in Czech Republic. In all public transport systems the strong passenger decline occurs during the observed time. That means the passenger choose another transport mode and mainly car. It is important to deal with public transport with the aim to ensure a competitive one, because from the society point of view public transport represents the lowest cost and environment friendly transport system.
Artykuł zajmuje się aktualną problematyką w publicznym zbiorowym transporcie osobowym w Republice Czeskiej. We wszystkich systemach publicznego zbiorowego transportu osobowego dochodzi, w ciągu rozważanego okresu czasu, do znacznego obniżenia ilości przewiezionych osób. To znaczy że potencjalny klient coraz to częściej wybiera inny sposób transportu, najczęściej samochód. Dlatego bardzo ważne jest zajęcie się zbiorowym transportem osobowym w celu zabezpieczenia jego zdolności do konkurencyjności. Z punktu widzenia społeczeństwa jest to najmniej kosztowny i zarazem ekologiczny system transportu ludzi.

Opis:
A unified approach is presented as the principle for a potential framework for evaluating driver schedules in public transport. There are two reasons for the need for such a framework. On the one hand, constructing optimal driver schedules is a challenging problem, and practical solutions cannot be compared to the optimum, which brings about the need to analyse the results with respect to an appropriate estimated value. On the other hand, the specific constraints and rules in different countries and for different companies make it difficult to model solutions in a unified way. Our new approach provides a solution to the above problems by employing an efficient general methodology from both the data modelling and process modelling point of view. By introducing the concept of reducible working time, our approach gives a realistic evaluation framework with an efficient solution method. The applicability of our approach is demonstrated through real-world cases.

Opis:
The programing documents of the European Union determine the direction of transport systems development, including large cities and agglomerations. The context of these actions which aim to transform into ecologically clean and sustainable transport system is a significant reduction of greenhouse gas emissions. Assuming that public transport will significantly reduce the use of combustion-powered buses, studies on urban logistic enabling the use of electric buses for public transport are needed. The article presents the variants and scenarios for electric buses implementation in urban public transport, as well as the decision algorithm to support electric bus implementation based on technological, organisational, economic and ecological variables.
Dokumenty programowe Unii Europejskiej wytyczają kierunki rozwoju systemu transportowego także w dużych miastach i aglomeracjach. Kontekstem tych działań, mających na celu przemianę systemu transportowego w transport ekologiczny i zrównoważony, jest znaczące ograniczanie emisji gazów cieplarnianych. Zakładając, że w transporcie publicznym nastąpi znaczne ograniczenie wykorzystania autobusów z napędem spalinowym, niezbędne są badania nad logistyką miejską, umożliwiające wykorzystanie autobusów elektrycznych do transportu publicznego. W artykule przedstawiono warianty i scenariusze wdrażania autobusów elektrycznych w publicznym transporcie zbiorowym oraz zaprezentowano algorytm wsparcia decyzji na podstawie zmiennych technicznych, organizacyjnych, ekonomicznych i ekologicznych.

Opis:
The transport accessibility of cities decreases with the increase in road traffic. Planners, traffic engineers, and road managers are looking for solutions that will reduce congestion on city streets without limiting transport accessibility to the city center. The article presents an overview of solutions used in Poland and abroad that aim to encourage people who travel by car to the city center to use other means of transport. The solutions were identified that can contribute to reducing road traffic in the city without limiting its transport accessibility based on the area inventory in Krakow. The next part of the article analyzes the use of P&R parking and the bike-sharing Wavelo system in Krakow in 2018. The results of the conducted analyses indicate that the most entrances to the P&R parking in Krakow were in the morning hours, whereas the most exits from these parking were in the afternoon. The holiday months were characterized by a lower use of parking space compared with the remaining months. These conclusions may indicate that the people using the analyzed parking lots are mainly commuters. On the contrary, the analysis of the use of the bike-sharing Wavelo system in Krakow allows for the conclusion that a large numer of people used rental bikes for short journeys. These trips can complement the journeys made with the use of public transport or as a continuation of the journey after leaving the car in the P&R parking. Investments and development of this type of solutions may be an incentive for people traveling by car to use another means of transport.

Opis:
We explore how a rapid rise in air pollutants impacts the ridership of public transportation. Based on the individual purchase history, our comprehensive analyses document evidence that an elevated level of concentrations of fine particulate matter caused a substantial change in individual decisions on public transit ridership in relation to individual social and economic characteristics. The estimated effect primarily arose from the fear of exposure to pollutants and, consequently, is substantially different from other macroeconomic influences. Our empirical results contribute important inferences about commuters’ choices of transit modes during the period of ambient air pollution and offer significant guidance for policymakers and practitioners.

Opis:
The dynamic development of cities based on the role of the car in addressing transport needs leads to a reduction of mobility, as well as to an increase in external costs generated by the transport system. This problem can be solved thanks to the sustainable mobility concept, in which transport needs are limited at the stage of planning spatial development and then covered by public transport as well as by cycle and pedestrian journeys. This article identifies arguments justifying the implementation of FFPT in Poland, and also evaluates their relevance based on the experiences described in the literature and the example of Żory. On this basis, it can be concluded that the evidence for the impact of FFPT on sustainable urban mobility is poor. Neither does FFPT reduce mobility exclusion. At the same time, the introduction of this solution is expensive, especially in the metropolitan areas.

Opis:
The aim of this paper is to develop a quantile method of cost analysis allowing identification of the most cost-generating malfunctions occurring in a fleet of public transport vehicles. The exemplification of this method has been performed for a fleet of a specified type of trams. The idea behind the quantile method of public transport vehicle operating cost analysis is the reversing of the accumulated function of costs, for the determination of which a cost database from a given operating time of a public transport vehicle fleet has been used. The paper presents data on the malfunctions from the first five years of operation of trams in a large transport company. The assumed time of five years results from the warranty period provided by the manufacturer. The recorded number of indexes of replaced parts was 547. The group contained inoperative parts that were renewed several times.

Opis:
The challenge in vehicle and crew scheduling is to arrange a given set of bus trips into running boards while minimizing certain objectives and complying with a given set of constraints. This scheduling was solved several tens years ago manually by a dispatcher who used his skill, experience, knowledge of history, and intuition. This attitude worked quite well in small instances but could not be applied in larger ones. Development of computers brought opportunities to build computerized vehicle and crew optimization systems. This paper describes a computer system KASTOR developed for vehicle and crew optimization, which complies with the special requirements of Czech and Slovak bus providers, and is significantly different from those in some west European countries.

Opis:
Public transportation plays a significant role in urban areas, transporting a large percentage of people. There is no existing study dealing with the balance between transportation demand and supply in Baghdad city; thus, there is a need to assess service equity before implementing any major services. The aim of the present research is to study the equity of transit need. The methodology uses geographic information systems (GISs) and spatial multi-criteria analysis to determine equity. Nine criteria were used in this study (land use, population density, commercial activities, medical locations, bus stops walkability, educational activities, bus terminal, and income) to determine a transit need map. Expert opinion surveys are conducted to determine pairwise comparisons between these criteria to estimate the weight of each criterion. Spatial analysis in ArcGIS 10.8 is utilized to apply methodology. The transit need map is obtained, and the need for transit service is represented by a value for each cell. In addition, the map output is important to public transit planning, as it maximizes the optimal transit route selection depending on the transit need. The output of this study (a transit need map) represents a powerful tool for the decision-makers to prioritize transportation programs and ranking alternatives. Gap analysis is used to measure equity between various zones. The results show that the transit supply provides higher service coverages in the Central Business District (CBD) and decreases as the distance to CBD increases.

Opis:
This article describes a way of synchronization of communication lines in urban public transport. In the literature, no comprehensive methods have been presented to ensure the regularity of running public transport vehicles, except specific cases of this problem, which have little practical application. It demonstrates how this problem is difficult. In the article, the problem was presented more broadly – running of vehicles in different intervals, in lots of common fragments of routes, and running periods was considered. The objective function for this problem was defined, and then the algorithms to solve it were discussed. In the next part of the work, a model was verified by making synchronization of the timetables of selected lines in Ostrowiec Świętokrzyski. Three lines from the twelve were included in the analysis. The routes of these lines created seven communication bundles (i.e. the common fragments of the routes) for which synchronization was required. The results of synchronization (obtained by an author software) were new departure Times of the lines from their start stops. Finally, they were confronted with the existing timetables, which confirmed the usefulness of the proposed method.

Opis:
Urban transport plays a massive role in the proper functioning of cities [1, 2]. Prioritisation of public transport [3] is an attempt to fight growing traffic congestion, which has a noticeable impact on people’s comfort of living, especially in large cities [4-6]. Shaping the road environment to improve the quality of functioning of public transport means that the management of urban infrastructure cannot cause difficulties. The continuous execution of construction works in Wroclaw has forced the ordering party to introduce temporary, and often complicated, traffic organisation solutions. The primary goal is to ensure the most efficiency for public transport users while maintaining the smoothness of private transport. This article presents solutions to temporary tram traffic organisation used in Wroclaw. The frequency and effects of the applied solutions were analysed using examples of completed and planned tram investments in Wroclaw. The reasons for the applied solutions and possible directions for further analyses were considered.

Opis:
Urban transport systems operate according to fixed, strict timetables, which requires high timeliness and technical readiness of the fleet. Therefore, this article proposes a detailed study of the punctuality of the public transport system using a multiple regression model for the main modes of transport (trams, buses, and Warsaw Metro). The analysis made it possible to go beyond the framework of the overall assessment and to identify the factors that have a significant effect on the punctuality index and to indicate the degree of this effect. The obtained results are a universal tool to assess the punctuality level of the urban transport fleet and to support decision making in the scope of organization of their work, which can be implemented in any similar transport system. The specification of the number of breakdowns, road accidents, or unauthorized stopping of a vehicle as the main causes of delays is the basis for taking corrective measures related to the improvement of the fleet operation system, or for preventive measures. The development of such models is practical in both public transport systems and similar companies providing transport services. For such institutions, the parameter of punctuality is extremely important and affects the quality of the services offered and the reputation of the company, which translates into the numer of customers and potential profit. Therefore, it is important to investigate the factors that shape the punctuality of the tasks performed. It allows for shaping the processes of fleet control and management. It is also worth emphasizing the scientific aspect of the publication, which is the presentation of the possibilities of applying selected mathematical models in such analyses, indication of the conditions of their application, and presentation of possible results together with their interpretation.

The paper deals with the issue of efficiency of public passenger transport through financial support from public funds from the perspective of improving road safety. The aim is to verify the hypothesis that financing public passenger transport from public funds is a significant tool to influence the number of passengers carried by individual automobile transport, and thus it can be used a tool for influencing road safety in a particular territory. The first part of the paper analyses the sources for financial support of public passenger transport. The next part describes the assumptions for improving road safety through increasing the support of public passenger transport. The last part analyses possible impacts of financing public passenger transport on the road safety in relation to the specified hypothesis.
