The accessibility of regional centers by public transport in a defined area is a very specific problem. Depending on the organization of public transport, there is a potentially related phenomenon – social transport exclusion. The aim of the study is to express the existence of a relationship between public transport and regional development in the rural self-governing region Trnava. At the same time, we identify municipalities – more precisely areas – with reduced transport accessibility in relation to their regional development and we determine the most advantageous means of public transport for the population who does not have the possibility to use a car. The procedure was to use an electronic database of train and bus timetables to obtain information about the studied characteristics for the return journey during the 24 hours of working days (Tuesday). We found that rail and combined transport have better quality in about half of the region’s municipalities. The Pearson correlation coefficient of product of moments indicated that the value of the correlation between the number of points for public transport and points for regional development is only 0.36, and therefore there is no strong connection between them. However, the individual extreme and average values of these indicators and especially their sub-components have shown us that there is a certain dependence between these values. The results show that despite a lower impact on public transport on regional development, it has a more decisive influence, leading to the strengthening of public transport.

The analysis presented herein is aimed at indicating disparities in accessibility to some selected travel destinations by means of private and public transport in the city of Szczecin. Accessibility is a simple measure of potential interactions between two points in space. For the purpose of the study, an original model of an individual transportation system has been developed using Google Maps API data. In order to do so, some GTFS and pedestrian-related data have been downloaded. To calculate source-destination travel times at certain times of the day for four different parameters of pedestrian motion speed, ArcGIS Network Analyst software has been used. Five research methods have been applied: the proximity measure, the population percentage measure, the cumulative accessibility measure, the potential accessibility index and the potential accessibility quotient. In order to develop an ultimate accessibility rating for housing estates in Szczecin, a synthetic accessibility measure has been developed. The synthetic accessibility measure consists of 9 standardised components/values for both public and private (car) transport. The potential accessibility to the population is part of the synthetic accessibility sub-measure. The isochrones have been drawn in order to analyse the workplaces and secondary schools. Moreover, data concerning accessibility to the nearest kindergarten, primary school, hospital, cinema, shopping centre and indoor swimming pool have also been taken into consideration when calculating the synthetic measure. In the case of potential accessibility measures, it is usually the highest in the city centre. Obviously, the nearer a particular facility, the higher its accessibility measure is. The only disparities between the measures for public and private transport are observed in areas which are not covered by the public transportation network.

One of the main transportation problems of biggest modern cities is the excessively high load on ground transport, which is why the development of subway networks is of particular importance. This article analyzes the development of the spatial structure of subway networks in China. Currently China shows an intensive growth of existing networks and massive openings of new networks, which makes it the most suitable object for studying the evolution of subway networks. The methodology developed by K. Kansky and S. A. Tarkhov was used as the theoretical basis of this study. The study was conducted by analyzing the dynamics of the main quantitative and topomorphological indicators of subway networks during their passage through the stages of spatial evolution. The following indicators were used: the number of subways, the total length of the network, the number of cycles in the network, the number of topological layers and the number of cycles in each of them, the number of branching tiers, the area of topological layers and their share in the cyclic core of the network, the distribution of the length between the elements of the network structure, average cycle size, topological limit, cyclization index and circuity index. We identified the patterns for passing the stages of evolutionary development by the networks of Chinese subways; also, we found common features that define the “Chinese” type of subway, we identified a new subtype of networks.

The aim of this study is to investigate how the daily electricity demand from road transport related to the implementation of an electric road system on the eight roads with the highest traffic flow connecting the seven largest cities in Turkey varies according to time and location. Intercity highway route O-7, O-5, O-21, D715, D687, E96, and E87 in Western Turkey was used as a case study. The daily electricity demand on the eight roads working on the full electrification of the existing traffic flow can be increased by 3.7% in the case of the reference point. However, if all roads in Turkey are converted to an electric road system and all land vehicles use this system, the corresponding peak power increase will be 100%. The daily electricity demand along the roads is derived from the available measuring points for the daily road traffic volumes. The study also compares the CO₂ reduction potentials and energy demands of the electrified road system with the use of fossil fuels to achieve the same transportation volume. The results show that an electric road system application on eight Turkish roads with considerable traffic flow can reduce 18.8 million tons of CO₂ emissions from the road transport sector. The research can find practical application in assessing the validity of developing a strategy for the development of electromobility on highways in Turkey.
