Previous studies of service-oriented tourist city networks have often focused on the analysis of the geographical distributions and service roles of important cities instead of the connections and hierarchical tendencies between different types of cities within a whole region. The current study uses big data approaches for the regional connections of 38 tourism organizations, including famous hotels, air passenger transport services, and tourism service agencies, across 63 of the most important tourist cities in China. Fuzzy c-means clustering analysis is used to define eight city arena clusters. According to the distributions of connectivity between the 63 cities, these eight clusters play different functional service roles in the urban tourism network in four hierarchies. With their “center–edge” memberships, these arena clusters are formed by the interweaved process of regional and hierarchical tourism service connections. The results here include analysis of the various service-oriented tourist cities in China and point out the geographical “gap” faced by networks. Service-oriented tourist cities need to find their hierarchies and positioning in the network, scientifically speaking, to avoid blind development and to support sustainable regional tourism development in urban areas.

[Background] Previous research achievements of the service-oriented tourist city network have often focused on the analysis of its geographical distribution and service role of the important cities instead of the connections and hierarchical tendencies between the whole city in a large region.[Method]Using big data approaches on the regional connections of 38 tourism organizations including famous hotels, air passenger transport, tourism service agencies across 63 most important tourist cities in China. Fuzzy c-means clustering analysis is used to define 8 city arena clusters. [Results]According to the distributions of connectivity between 63 cities, these eight clusters play different service functional roles in the urban tourism network at four hierarchies. With their “center-edge” memberships, these arena clusters are formed by the interweaving process of regional and hierarchical tourism service connections. The results include the analysis of the various service-oriented tourist city in China and point out the geography “gap” faced by network. [Conclusion] Service-oriented tourist cities need to find their hierarchies and positioning in the network scientifically to avoid blind development, to make regional urban tourism sustainable development.

Platformization affects the entire urban transport sector, effectively blurring the division between private and public transport modalities; existing public–private arrangements have started to shift as a result. This chapter analyzes and discusses the emergence of a platform ecology for urban transport, focusing on two central public values: the quality of urban transport and the organization of labor and workers’ rights. Using the prism of platform mechanisms, it analyzes how the sector of urban transport is changing societal organization in various urban areas across the world. Datafication has allowed numerous new actors to offer their bike-, car-, or ride-sharing services online; selection mechanisms help match old and new complementors with passengers. Similarly, new connective platforms are emerging, most prominently transport network companies such as Uber and Lyft that offer public and private transport options, as well as new platforms offering integrated transport services, often referred to as “mobility as a service.”

Electric cargo bicycles have become a popular mode of transport for last-mile goods deliveries under conditions of restricted traffic in urban areas. The indispensable elements of the cargo bike delivery systems are loading hubs: they serve as intermediate points between vans and bikes ensuring loading, storage, and e-vehicle charging operations. The choice of the loading hub location is one of the basic problems to be solved when designing city logistics systems that presume the use of electric bicycles. The paper proposes an approach to justifying the location of a loading hub based on computer simulations of the delivery process in the closed urban area under the condition of stochastic demand for transport services. The developed mathematical model considers consignees and loading hubs as vertices in the graph representing the transport network. A single request for transport services is described based on the set of numeric parameters, among which the most significant are the size of the consignment, its dimensions, and the time interval between the current and the previous requests for deliveries. The software implementation of the developed model in Python programming language was used to simulate the process of goods delivery by e-bikes for two cases—the synthetically generated rectangular network and the real-world case of the Old Town district in Krakow, Poland. The loading hub location was substantiated based on the simulation results from a set of alternative locations by using the minimum of the total transport work as the efficiency criterion. The obtained results differ from the loading hub locations chosen with the use of classical rectilinear and center-of-gravity methods to solve a simple facility location problem.

The Cost

Vehicular traffic has increased across all over the world especially in urban areas due to many reasons including the reduction in the cost of vehicles, degradation of the quality of public transport services and increased wealth of people. The traffic congestion created by these vehicles causes many problems. Increased environment pollution is one of the most serious negative effects of traffic congestion. Noxious gases and fine particles emitted by vehicles affect people in different ways depending on their age and present health conditions. Professionals and policy makers have devised schemes for better managing traffic in congested areas. These schemes suffer from many shortcomings including the inability to adapt to dynamic changes of traffic patterns. With the development of technology, new applications like Google maps help drivers to select less congested routes. But, the identification of the best route takes only the present traffic condition on different road segments presently. In this paper the authors propose a system that helps drivers select routes based on the present and expected environment pollution levels at critical points in a given area.

Traffic congestion is an enormous problem at peak hours in western province. Existing transport system is not capable to overcome these complexity situations. Therefore, Srilankan government needs to find out different mode of transport to save time and money and finally economy of the country. In the past history, there was a rich water transportation system over the country. Specially, the western province has a well-distributed network of inland waterways, comprising of main rivers, streams, canals, lakes, and tanks. Most of the time, the existing waterways were used for freight transportation (timber, sand, brick, and tiles. compare to Public transportation. The study is to determine the efficient use of waterways for the public transportation focusing the travel time and fuel consumption. The existing water way network was map and find availability of other network connectivity using ArcGIS and Google Earth Pro software. Then compare it with an existing public transportation mode (bus) and checked the suitability of usage of water transportation as an alternative to reduce the existing traffic congestion problem. And proposed water way transport system, that capable of potential and strategic way to reduce the traffic congestion problem in Colombo and its sub urban areas.

Rural areas still have some disadvantages in comparison to urban areas. Access to jobs, education, or health services provided for inhabitants in rural areas are limited. Another important topic is mobility, which is crucial to meet the travel expectations of inhabitants in rural areas. Finding new forms of mobility capable of covering all areas and meeting the requirements of rural inhabitants is the most important challenge. This chapter deals with mobility in rural areas from the perspective of demographics, social change, and accessibility to transport services. Moreover, this chapter offers various case studies dealing with innovative solutions for mobility in rural areas resulting from the RUMOBIL project.

A lack of transport opportunities has been shown to be a barrier for accessibility and social inclusion in contemporary society. In rural and sparsely populated areas, access to public transport is often poor compared to urban areas, leading to fewer possibilities to participate in normal relationships and activities among rural dwellers. Based on qualitative interviews with rural dwellers in Sweden, the aim of this study was to explore how access to transport can meet the needs of mobility and activity participation in everyday life and how different modes of transport are being used. The study has been permeated by the time-geographical perspective, which considers people’s use of time and space and the restrictions they face in order to carry out activities, including travel. The results show that travel by private car plays a central role in realizing everyday activities for rural dwellers, as well as a perception of the car as being the norm in contemporary society. Frequent car use is the consequence of a combination of time-space restrictions, habit, and a lack of services, activities, and public transport in rural areas. Poor public transport services limit children’s and adolescents’ independent mobility in particular. Further, the physical environment influences the ability to use public transport, for example if roads and bus stops are seen as unsafe. Based on the results of the study, several measures and improvements are proposed that could increase mobility and accessibility in rural areas and reduce car dependency.

Introduction. The paper discusses the problems of organizing the vehicles’ parking near large shopping centers and also describes their relevance, taking into account the transport services of retail outlets and residence places. The authors present the research of the problem by leading scientists, which is reflected in the regulatory documentation.Materials and methods. The authors used a mathematical description of the average parking duration and identified the main affecting factors, taking into account the proportion of workers in the mass gravity center. The authors proposed a mathematical dependence based on the average parking duration, taking into account reservation of parking places for workers and the required number of parking spaces for other categories. The paper considered the possibility of the intra-hour deficit of parking places based on the PHF-factor.Results. As a result, the authors made the comparison of the obtained values of the required parking spaces with the standard ones. The paper provided more than 30 types of mass gravity centers and urban areas. In addition, the authors considered the examples of assessing the required number of parking spaces near a large housing estate at the 8 km distance from the city center. Therefore, the authors proposed the technique for assessing the required number of parking spaces based on normative values per 100 m2 of the area of the mass gravity centers.Discussion and conclusions. The authors present recommendations are made for the practical application of the required number of parking spaces by the normative values.Financial transparency: the authors have no financial interest in the presented materials or methods. There is no conflict of interest.

Abstract In a situation of increasing the supply of means of individual transport and not capable of following the development of infrastructure, an important issue is the issue of ensuring adequate levels of efficiency, safety and the competitiveness of the operation of the exploitation of public transport services. Factors affecting the safe operation pending exploitation systems of vehicles, in a differentiated way affect the level of safety provided services in smaller cities - up to 100 thousand inhabitants, with respect to the cities which are agglomerations of more complex structure, which are cities the number to 500 thousand inhabitants. This paper attempts to analyze and evaluate the safety of the operation of the public transport services exploitation, on the basis of the same assessment criteria, comparing two different sized urban areas.
