City activity fluxes are reminiscent of stakeholder mobility in the urban sphere service and functions. Such mobility affects income and work assiduity though often creating accidents, material damage and pollution of varied forms of urban transportation that has lately witnessed the adaption to motorbikes as an alternatively favoured means of movement to that car. Salvaging economic depression and affordability has given biking an edge of success of recent which raises the recurrent question of its spatio-temporal and technical sustainability in in the freight sector. This paper evaluates the commercialisation of bike riding despite levied negativism perceptions in providing an alternative to the major urban problem of traffic congestion and its contribution to peter the pitfalls of the congestion. To assess the urban congestion intensity, traffic flow count was conducted during the rainy and dry season of spatio-temporal of vehicles (from the city centre to the suburbs). Findings agree to the fact that vehicular traffic congestion with increasing number of bikes was found to be higher along the N-E than the N-W road axis in direct conformity with sampled urban congestion triggers for Bamenda related to road infrastructural traits and vehicular numbers. Though motor bikes initially were a panacea, the sum effect of congestion reveals the urgent need for urban mass transport systems that should be complemented by a holistic urban transport governance involving the creation of deviation routes and enforcing traffic congestion rules.

Knowledge about urban forests in Poland is still limited, as it is primarily based on aggregate, formal data relating to the general area, ignoring the spatial dimension and informal green areas. This article describes and analyses spatio-temporal changes in the actual urban forest resources in Wrocław in 1944–2017, which covers the first period of the city’s rebuilding after its destruction during World War II and its development during the nationalised, centrally-planned socialist economy, as well as the second period of intensive and only partly controlled growth under conditions of market economy. The study is based on current and historical orthophotomaps, which were confronted with cartographic data, as well as planning documents. We found that between 1944 and 2017, the percentage contribution of informal woodlands increased tenfold (from 0.5 to 4.9% of the present total area of the city). The area occupied by such forests has grown particularly during the most recent years of the city’s intensive development. However, the forests have been increasingly fragmented. During the first period, new forest areas were also created in the immediate vicinity of the city centre, while during the second one, only in its peripheral sections. The post-war plans regarding the urban green spaces (UGS), including the current plan, are very conservative in nature. On the one hand, this means no interference with the oldest, biggest, and most valuable forest complexes, but on the other hand, insufficient consideration of the intensive built-up area expansion on former agriculture areas. Only to a limited extent did the above-mentioned plans take into account the informal woodlands, which provide an opportunity for strengthening the functional connectivity of landscape.

Cilegon is one of the National Activity Centre (PKN) in Banten Province. As PKN, Cilegon generate movement from out of town towards Cilegon, either using AKAP/AKDP buses and urban transportation from the place of origin. Many AKAP/AKDP bus passengers fell in the shadow of the terminal, while the urban transport passengers from the outside get into the city of Cilegon and drop off passengers . The number of outer urban transport operating in Cilegon Cilegon City area adds to congestion in Jalan Sultan and Jalan Ahmad Yani Ageng Tirtayasa , especially at rush hour. Therefor, the Government of Cilegon Municipality then implement the construction of SeruniTerminal, officially put into operation on April 1, 2013. With the expected Seruni terminal buses no longer drop off passengers at the terminal shadow, and urban transport outside the city of Cilegon not get into town. Positivistic approach and methods used in this study is a quantitative method , as well as some analysis used : (1) the analysis of the characteristics of SeruniTerminal, (2) analysis of traffic volume in Seruni Terminal, (3) analysis of urban transport route network in Cilegon, and (4) policy analysis for development of The Seruni Terminal, is expected to answer the research question, namely : " the role of Seruni Terminal in the urban transport system in Cilegon Municipality? "The results obtained from this study is the lack of Seruni Terminal has a role in urban transport systems in Cilegon. To enhance the role, it’s can be done with urban transport route A.01 Cilegon-Anyer and Merak-Cilegon M.01 directed toward Seruni Terminal, and/or the addition of a new trajectory Cilegon-JLS. Therefor, Seruni Terminal is expected to increase the role of the movement in serving urban communities in Cilegon.

Progress towards the UN Sustainable Development Goals (SDGs) is being evaluated through the use of indicators. Despite the importance of these indicators, the academic community has done little in terms of a critical reflection on their choice, relevance, framing and operationalization. This holds for many SDG domains, also for the urban sector domain of target 11. To partially address this void, we aim to critically review the UN methodology for the urban access indicator, SDG indicator 11.2. In discussing its conceptual framing against the background of paradigm shifts in transportation planning, we argue that this indicator has a number of shortcomings. The most important one is that it is supply oriented and measures access to transportation infrastructure, rather than accessibility to activity locations. As an alternative, we develop two accessibility indicators that show substantial variation in accessibility across geographical areas. We implement all indicators for the city of Bogotá in Colombia, using a geo-information based approach. Our results show that SDG indicator 11.2 fails to represent the transport reality well. Its supply oriented focus neglects transport demand, oversimplifies the transport system and hides existing inequalities. Moreover, it does not provide useful evidence for targeting new interventions. The proposed accessibility indicators provide a more diverse, complete and realistic picture of the performance of the transport system. These indicators also capture the large spatial and socio-economic inequalities and can help to target improvements in urban transportation.

Recent advances in spatial and temporal networks have enabled researchers to more-accurately describe many real-world systems such as urban transport networks. In this paper, we study the response of real-world spatio-temporal networks to random error and systematic attack, taking a unified view of their spatial and temporal performance. We propose a model of spatio-temporal paths in time-varying spatially embedded networks which captures the property that, as in many real-world systems, interaction between nodes is non-instantaneous and governed by the space in which they are embedded. Through numerical experiments on three real-world urban transport systems, we study the effect of node failure on a network's topological, temporal and spatial structure. We also demonstrate the broader applicability of this framework to three other classes of network. To identify weaknesses specific to the behaviour of a spatio-temporal system, we introduce centrality measures that evaluate the importance of a node as a structural bridge and its role in supporting spatio-temporally efficient flows through the network. This exposes the complex nature of fragility in a spatio-temporal system, showing that there is a variety of failure modes when a network is subject to systematic attacks.

This paper presents theoretical comments on the “Taiyuan’s Urban Master Planning (2010-2020)” mainly in the aspects of the city's orientation, functions, urban transportation and eco-environmental planning. It can be seen that the master planning have a new scientific orientation of the city of Taiyuan by perceiving it as “a historic ancient capital of culture"; sufficient attention is paid to the relocation, renovation and update of TISCO, TCIGO and other heavy chemical companies; the newly designed urban public transit passenger transport organization mode is utilized to settle the increasingly prominent urban transport problems; tourism development is promoted under the premise of the protection of ecological environment as well as historical and cultural heritages; a number of shortcomings and recommendations for improvement are also proposed, trying to provide decision-making references for further adjustments and improvements of Taiyuan’s urban planning.

In many world’s most populous cities, railways are an integral part of urban transport systems. Commuter and intraurban passenger railway traffic is often and widely considered in this context. On the other hand, the constant growth in passenger traffic of longdistance trains, traditionally gravitating towards railway stations and adjacent urban transport hubs, including metro stations through which arriving passengers pass towards their final destinations in the city, requires search for new solutions to improve comfort of the trip for passengers, and to remove the excess load from the urban transit system. Considering the experience and features of organization of long-distance passenger railway traffic in various countries, the authors based on previous research suggests certain solutions regarding Moscow railway hub. To organize comfortable environment for passengers of all categories of trains, it is advisable to develop a balanced technology of train traffic within the Moscow junction, excluding overloading of individual elements of the transport system (in particular, of rail stations in the city center). The objective of the article is to analyze global experience in organizing traffic of long-distance passenger trains within the boundaries of large agglomerations and to develop proposals to organize additional stopping points for long-distance trains in various districts of Moscow, which will help reduce the load on central transport and interchange hubs, improve quality of transportation services for passengers, and develop the districts of Moscow and Moscow region adjacent to the new TIHs.

The article is devoted to the establishment of information support to determine the patterns of changing the function of gravitation of employees of the urban-service enterprises. It has been established that the development of urban transport systems is impossible without the use of information technology to predict the parameters of the formation and absorption of passenger traffic. The design of urban transport systems cannot be achieved without assessing the impact of traffic improvement measures on changes in traffic and passenger flows. The main parameter by which it is possible to predict the choice of places of gravity by the inhabitants of cities is the function of gravitation between different areas of the city. The formalized functions of the gravitation of urban dwellers are not differentiated by the social composition of the population of cities. In addition, they use only travel time between areas of the city as an independent variable. The article proposes the formalization of the gravitation function of employees of the urban service enterprises using the parameters of the urban transport system, areas of departure and arrival, as well as the cost of movement. A special questionnaire has been developed to obtain the original information. A natural survey was carried out using it. As a result of the processing of survey data using correlation and regression analysis methods, the degree of influence of the studied factors on the value of the gravitation function of employees of urban service enterprises was revealed. Analysis of the correlation values obtained showed that the most significant impact on the value of the gravitation function of employees of urban services is the ratio of the cost of movement between districts and average wages in the city. The least impact is the distance from the area of residence to the place of application of work, the ratio of the cost of one square meter of housing in the area of residence and the average salary in the city, the ratio of the cost of one square meter of housing in the area of employment application and the average salary in the city. However, the compatible influence of all factors can change the level of influence of each factor and its combinations. In addition, it is advisable to take into account the technical and operational performance of urban passenger transport routes and individual transport routes.

In this paper innovative urban individual transport systems have been discussed. The results of the survey conducted on a group of 250 people, of which the largest part were residents of the city in the youngest age group 18-24 shows that knowledge about modern forms of transport and the possible willingness to use them, is not at a high level. The reason is the attachment of society to material goods and lack of awareness about the benefits that the user gains, but also the inhabitants in the aspect of improving the quality of life in the city. The future of transport belongs to systems that are focused on the lack of belonging and sharing economy. The concluded analysis proves that the systems functioning in the States are profitable and convenient for the residents, and the companies constantly develop their offer by expanding with modern solutions and facilities. In Poland, the change of residents habits regarding the forms of mobility will occur with the increase of popularity of modern systems, and this can be obtained by emphasizing the promotion in means of transport, at bus stops, and in the media. Forecasts indicate a steadily growing market value of innovative urban transport systems, which will improve the standard of living in crowded cities.

AbstractWe present a comprehensive analysis of four south föhn events observed during the Penetration and Interruption of Alpine Foehn (PIANO) field campaign in the Inn Valley, Austria, in the vicinity of Innsbruck. The goal is to detect and quantify processes of cold-air pool (CAP) erosion by föhn as well as processes of föhn breakdown. Despite differences in föhn breakthrough and strength, the four cases exhibit similarities in CAP evolution: initially, the CAP experienced strongest warming in the centre of Innsbruck, where the föhn jet from the Wipp Valley interacted with the CAP in the Inn Valley. The resulting shear-flow instability at the föhn–CAP interface caused turbulent CAP erosion and, together with vertical warm-air advection, led to CAP depression over the city centre. This depression drove pre-föhn westerlies near the surface that caused cold-air advection inside the CAP west of the city centre and warm-air advection in the east. Ultimately, the latter contributed to stronger CAP erosion in the east than in the west. This stronger heating also explains the preferential initial föhn breakthrough at the valley floor east of Innsbruck. In two of the cases, subsequent westward propagation of the föhn–CAP boundary across the city accompanied by northerly (deflected) föhn winds led to a complete föhn breakthrough. Föhn breakdown occurred either by a backflow of the CAP remnant or by a cold-frontal passage. This study emphasizes the importance of both turbulence and advection in the CAP heat budget and reveal their large spatio–temporal variability.

Modern conditions of the development dictate new conditions for the improvement and operation of urban transport. It is primarily due to the heavy traffic of urban transport networks and a change in the approaches to their exploitation. However, the objective economic situation does not provide opportunities for the full use of its potential. Thus, the full and rational use of existing opportunities becomes possible only in case of determining the priority directions of its development, and, accordingly, their implementation, which in turn updates the research and forms its purpose. In this way, the involvement of foreign experience in the operation of the urban transport system, taking into account national realities, is of great importance. The main approaches to the elements of the urban transport are defined. The key components of this system are outlined. The main models of regulation and financial provision of the urban transport system have been investigated. The experience of European countries in this area has been systematized. The main directions of the development of the urban transport systems in Ukraine have been proposed.
