In order to highlight the subjective criticality of each neighbourhood to inspire future policy actions, we propose an analysis comparing the perceptions of over-65s residents in the neighbourhoods that make up the Municipality of Genoa. We suggest a new approach based on a quantitative non-aggregative method, Partially Ordered Set (Poset), to measure the levels of satisfaction related to local public transport (LPT), pedestrian mobility, and quality of life in the 25 districts of Genoa. Final data of the analysis come from 401 questionnaires, distributed to residents over 65 years old in the Municipality of Genoa. This approach allows to address the multidimensionality of the phenomenon, as well as its different conceptual spheres. The findings highlight a great variance in local public transport needs perception between different neighbourhoods. In particular, the analysis shows that the types of intervention requested by respondents differ from district to district, so that a common urban transport policy would be ineffective. Some neighbourhoods stress the need for improving pedestrian mobility, whilst local public transport faults dominate in others. There is no significant relation between the three dimensions: Perceived quality of LPT, perceived quality of pedestrian mobility, and perceived quality of neighbourhood. Therefore, interventions should be carefully modulated, according to the specific needs expressed by the residents of each neighbourhood. We conclude that the importance of urban mobility intervention is reduced, whereas the concept of neighbourhood analysis and intervention becomes more relevant.

Sustainable Mobility

New challenges of urban transport are connected to sustainability, the growing urban population globally, life quality and quality of urban environment, reduction of pollution and energy consumption. Sustainable urban mobility is no more dependent only on passenger transport efficiency, but also on transport accessibility of commuting services, acceptable level of comfort, safety and security of urban public transport and many more. Although a huge amount of data are available from modern communication services, the question of how to use those big data efficiently to improve urban mobility is unknown. Positive changes of mobility attitudes and travel behavior of citizens are going slowly, which means that personal motivation do not follow big data availability. This motivation is dependent on quality of public transport offer and services, among which information services are suspected to play a crucial role. Modern ICT methods of transport information delivery are based on Internet and social media, which through commonly used mobile devices are available at every stage of journey. In this article authors try, based on the pilot survey, to check how young Krakow citizens use social media in every day travels and commuting. The overall goal of the author’s study is to answer the question: how to use big data coming from ICT in order to upgrade urban transport sustainability.

Sustainable mobility is becoming a key factor in improving the quality of life of the residents and increasing physical activity (PA) levels. The current situation of sustainable mobility and its analysis is a first step in understanding the factors that would encourage residents to discover and choose alternative modes of travel. The present study examined the factors that encourage the choice of active modes of travel among urban adult population. Walking and cycling were analyzed as the most sustainable forms of urban mobility from the perspective of car and public transport (PT) users. Total of 902 subjects aged 18 years or older were analyzed in the study to assess commuting habits in Kaunas city, Lithuania. The majority (61.1%) of the respondents used a passenger vehicle, 28.2% used PT, and only 13.5% used active modes of travel. The results showed that safer pedestrian crossings, and comfortable paths were the most significant factors that encourage walking. A wider cycling network, and bicycle safety were the most important incentives for the promotion of cycling. Our findings show that the main factors encouraging walking and cycling among car and PT users are similar, however, the individual characteristics that determine the choice of these factors vary significantly.

Cone Beam Computed Tomography (CBCT) is the preferred imaging method for a comprehensive orthodontic examination. Thanks to the development of this technique, clinicians today can make most accurate measurements without fear of errors associated with projection distortion or localization of landmarks on radiographs. The quality of CBCT images gives to orthodontists the ability to analyze bone structures, teeth (even impacted teeth), and soft tissue in three dimensions. The accuracy of measurements of hard and soft tissues from CBCT images determines the accuracy of diagnosis and treatment planning. A fundamentally new approach has been proposed, which makes it possible to thoroughly study the bone tissue surrounding the tooth at the stages of planning orthodontic treatment. Аnalysis of radiation studies of patients with dentoalveolar anomalies was carried out to select the optimal treatment tactics and to control its effectiveness.

This study assesses changes in mobility behaviour in the City of Barcelona due the COVID‐19pandemic and its impact on air pollution and GHG emissions. Urban transport is an important sourceof global greenhouse gas (GHG) emissions. Improving urban mobility patterns is therefore crucial formitigating climate change. This study combines quantitative survey data and official governmentdata with in‐depth interviews with public administration officials of the City. Data illustrates thatBarcelona has experienced an unprecedented reduction in mobility during the lockdown (a 90%drop) and mobility remained at comparatively low levels throughout the year 2020. Most remarkableis the decrease in the use of public transport in 2020 compared to pre‐pandemic levels, whereas roadtraffic has decreased to a lesser extent and cycling surged at times to levels up to 60% higher thanpre‐pandemic levels. These changes in mobility have led to a radical and historic reduction in airpollution, with NO2 and PM10 concentration complying with WHO guidelines in 2020. Reductions inGHG emissions for Barcelona’s transport sector are estimated at almost 250.000 t CO2eq in 2020 (7%of the City’s overall annual emissions). The study derives policy implications aimed at achieving along‐term shift towards climate‐friendlier, low‐emission transport in Barcelona, namely how torecover lost demand in public transport and seize the opportunity that the crisis brings for reform byfurther reducing road traffic and establishing a 'cycling culture' in Barcelona, as already achieved inother European cities.

Sustainable Urban Mobility

The growing demand for passenger and freight transport in cities, resulting from the population growth in urbanized areas, has led to increasing problems with congestion, environmental pollution and, as a consequence, to a decrease in quality of life. This problem was noticed by the European Commission, which began to promote the concept of sustainable urban mobility plans (SUMPs). The efficient implementation of SUMPs requires tools for its evaluation. However, in the literature, most proposed assessment tools relate mainly to passenger transport, omitting the freight transport. The purpose of this paper is to utilize a multiple criteria analysis with the use of the Promethee method in order to assess the level of advancement of selected European Union (EU) capital cities in the field of sustainable urban mobility plan formulation and implementation. This method has been applied on the basis of a survey conducted among representatives of 15 EU capital cities and analyses of transportation plans. This research shows that cities that have a comprehensive transport plan consistently collaborate with different stakeholder groups, have implemented the greatest number of measures in the field of sustainable urban transport, and have achieved the best results in terms of safety and NO2 (nitrogen oxides) and PM (particulate matter) emissions.

The public urban transport market takes the form of a natural monopoly. In some cases, especially in the situation of supply of a relatively large volume of operation work, the implementation of competitive solutions may result in: improving the quality of services or reducing the cost of vehicle-kilometers. The purpose of the article is to present the determinants of functioning of regulated competition on the public urban transport market in Poland. The conducted analysis focuses on the issue of market openness and access to participation in competitive procedures of private operators. The research covered urban transport markets in cities over 200.000 inhabitants and their characteristics in the scope of: the model of public transport organization (with particular emphasis on the level of opening of markets), the level of competition on the operator market and the method of selecting operators. On the basis of the conducted research, the scope of applying pro-competitive solutions in the scope of contracting services by the largest organizers of public urban transport in Poland was characterized.

The City

A properly functioning public transport is one of the most important components of urban mobility for the population. Due to spatial inhomogeneity and overall socio-economic differences within a city, there are often considerable disproportions in the quality of transport services within its districts. Also, the city of Krakow is no exception in this case. For a comparison of public transport accessibility in 18 Krakow districts, 7 major quantitative and 5 minor indicators were created. These indicators include the most important characteristics of transport services such as accessibility, frequency, connectivity of connections, and ratios of tram public transport subsystem. The resulting values give a fairly comprehensive picture of the quality of the transport services. Overall higher values for most indicators occur in the central districts of the city. However, due to the complexity of the observed characteristics, it is possible to discover significant differences in the structure of individual indicators. Peripheral districts reach higher amplitudes, which means that in some aspect they have even better transport services than the city center. Yet, at the same time, we also find opposite extremes here, highly below-average values for most other indicators. A detailed analysis of the results provides a unique perspective on the disparities among districts. It can also serve for specific identification of strengths and weaknesses of transport services and its possible optimization.

The intensification of public transport in urban areas due to increased mobility at the regional and state levels, discrepancies between urban areas with the same population and the lack of statistics related to the efficiency and quality of public transport services are the main factors of our work. It is necessary to draw boundaries between the quality of services and the performance indicators of the public transport system. The quality of services is the subjective result of many intangible variables. The quality of service can be approached from four sides: from the point of view of the passenger, the performance of the vehicle, the specialized passenger transportation company, and the Government. Accessibility, comfort and convenience-these are the main indicators that should be evaluated by the population as having high ratings for the good quality of urban transport services. The tool used to collect the data is the preference survey. Keywords: service quality, public transport, evaluation, efficiency, methods, passenger, survey
