The article focuses on the issues of organizing transport services for visitors of the focal points (FP) using individual transport (IT). The main factors influencing the generation of transport demand arising from the focal points functioning are considered. The authors present the mathematical models that allow assessing the following variables: the traffic flow intensity arising during the transport service of individual transport users both at the entrance to the focal point territory and at the exit from it; the value of the load factor of the given group of lanes at the signalized intersection; the value of delay that occurs when visiting focal units using individual transport. The authors elaborate recommendations for the practical application of the considered mathematical models while organizing transport services for focal points visitors using individual transport.

The article discusses the issues of assessing the delays connected with the transport service of people visiting focal points (FPs) by individual transport (IT). The necessity of using a mathematical approach when assessing delays is proved. The factors influencing transport delays when driving through unsignalized intersections are presented. An integrated mathematical model is derived, which makes it possible to estimate the load factor at unsignalized intersections. This model is based on parameters that reflect transport demand and throughput capacity of an unsignalized intersection. The main parameters required for assessing the capacity of the minor road at an unsignalized intersection are described. An integrated mathematical model is offered that allows estimating the delay of individual transport users leaving the territory (parking lot) of the focal point. The authors elaborate recommendations for the practical application of the considered mathematical models while organizing transport services for focal points visitors using individual transport.

The intense growth of cities affects their inhabitants to a considerable extent. The issues facing the traveling population include congestion and growing harmful emissions. Urban transport requires changes towards eco-friendly solutions. However, even though new forms of traveling (sharing services) are being implemented, their integration with public transport remains problematic. On account of the large number of available services combined with the absence of their integration, city inhabitants are faced with the dilemma of choosing between one or several transport modes which would enable them to make the given trip. The main goal of this article is to propose a model for integration of different transport services which could support those who intend to travel in the decision-making process. Therefore, the parameters of a model of urban sharing services were identified and classified. The parameters discussed in the paper with reference to an extensive literature review describe how individual sharing services are functioning. What has also been identified is the location-specific factors as well as those related to the potential area of operation which affect the integration with public transport. In order to take all the relevant parameters into account and find a solution to the problem at hand, a multi-criteria decision-making approach has been proposed. To this end, scores and weights determining their impact on the model have been established. For purposes of the solution in question, the relevant calculations were conducted by referring to an actual need to travel between selected locations.

We consider the class of two-dimensional maps of the plane for which there exists a whole one-dimensional singular set (for example, a straight line) that is mapped into one point, called a "knot point" of the map. The special character of this kind of point has been already observed in maps of this class with at least one of the inverses having a vanishing denominator. In that framework, a knot is the so-called focal point of the inverse map (it is the same point). In this paper, we show that knots may also exist in other families of maps, not related to an inverse having values going to infinity. Some particular properties related to focal points persist, such as the existence of a "point to slope" correspondence between the points of the singular line and the slopes in the knot, lobes issuing from the knot point and loops in infinitely many points of an attracting set or in invariant stable and unstable sets.

The survey, which consisted of counting, polling and recording, has provided data on the existing volume of passenger flows in public bus stations/terminals within the Primorsko-goranska (Littoral-Mountainous) County (hereinafter: the PG County), the density rate of passengers on bus lines that operate on County connections and on bus lines connecting the PG County with other counties in Croatia. In addition to the quantitative parameters, the qualitative data were analyzed that had been obtained by polling passengers at the Rijeka bus terminal, whereupon detailed opinions of direct users of the service were elaborated with the aim of obtaining a picture of the current situation of the public bus transport in the PG County. The data collected were used in evaluating the quality of the passenger transport service provided and in determining measures to be taken in order to bring both the actual quality of transport and the satisfaction of passengers to a higher level.

Abstract Planning the extent of transport services within a selected territory is a topical issue especially in the context of developing integrated transport systems. The objective of this research study is to design a sustainable system of public passenger transport that would be an alternative to expanding individual transport. The implementation of a quality and efficient transport service is a relatively complex process, since, currently, there are no generally applicable principles for its design. This manuscript presents general results of research aimed at solving the problem of transport service within a selected territory issue with a focus on rail transport as an efficient transport system representing a backbone of a transport system. The subject of the investigation is to compile a set of factors affecting the design of the transport concept. The output of the manuscript consists in a proposal of a generally applicable procedure including a calculation of transport potential and characteristics of the inputs. Subsequently, based on the resulting values, it will be possible to determine the extent of the transport services provided by rail transport in any territory, which will contribute to a more efficient and high quality theoretical graph of train running.

Online transport service is currently popular in Indonesia. Not only provide ride-sharing service, but also other services such as food delivery, medicine delivery, and courier service. Ease of use and low cost make online transportation service more favored by consumers. However, this service has several disadvantages that cause inconvenience to the user until the occurrence of fraud action by the driver or the customer. Therefore identification of system deficiencies needs to be done to improve the security and convenience of customer and drivers of online transport services. This paper will analyze the problems of online transportation services applications through cases that have occurred and complaints of users of online transport applications. Through this analysis, we propose solutions to protect consumers and drivers for the security of transactions.

Multimodal transport can bring the technical and economic advantages in different transportation modes into full play. While ensuring the level of service, it can reduce energy consumption and transport costs. Governments of most countries are actively promoting it. Therefore, it has become a research hot spot. Being a green, fast, and all-day transport mode, railways play an important role in multimodal transport. This article aims to analyze a multimodal transport service quality indicator system involving railways from the perspectives of customers, multimodal service providers, and governments. Qualitative and quantitative research methods were adopted to analyze the secondhand data of academic papers, government policy, and industry reports to clarify the quality characteristics of multimodal transport services. Using grounded theory and to analyze firsthand data from in-depth interviews with multimodal transport practitioners, 25 evaluation indicators of container multimodal transport service quality were chosen to be the evaluation index system. To test and improve the evaluation scale, 270 valid questionnaires were analyzed using SPSS 24.0 and AMOS 21.0 software, including reliability analysis, exploratory factor analysis, and confirmatory factor analysis. The results show that all the indicators meet the standard requirements and have good reliability and validity.

Peculiarities of transport services for the transportation of passengers, which must be taken into account when creating logistics models for organizing and managing passenger flows, are considered. Need of cost reduction of time of passengers for transport service is proved. The conclusion is drawn on need of the effective transport system creation, for the purpose of observance of intervals of the movement of buses on routes. The possibility of use of architectural approximations classes for the solution of transport logistics problems is analysed. The methods used for solving transport problems where the most widespread is modeling and algorithmization of the determined task formulation strategy with use of a classical algorithm of mathematical programming are considered. The prospects of a meta-heuristic method use is a genetic algorithm for the solution of tasks of the control of city passenger transport adapted to objective conditions are proved. The main features of genetic algorithms consisting in an opportunity by optimization to use criterion function and to consider the necessary number of restrictions are defined. The structure of a chromosome which represents the coded option of the movement of the bus in real time depending on a road situation is received.
