Urban areas are subject to subsidence due to varying natural and anthropogenic causes. Often, subsidence is interpreted and correlated to a single causal factor; however, subsidence is usually more complex. In this study, we adopt a new model to distinguish different causes of subsidence in urban areas based on complexity. Ascending and descending Sentinel-1 data were analyzed using permanent scatterer interferometry (PS-InSAR) and decomposed to estimate vertical velocity. The estimated velocity is correlated to potential causes of subsidence, and modeled using different weights, to extract the model with the highest correlations among subsidence. The model was tested in Alexandria City, Egypt, based on three potential causes of subsidence: rock type, former lakes and lagoons dewatering (FLLD), and built-up load (BL). Results of experiments on the tested area reveal singular patterns of causal factors of subsidence distributed across the northeast, northwest, central south, and parts of the city center, reflecting the rock type of those areas. Dual causes of subsidence are found in the southwest and some parts of the southeast as a contribution of rock type and FLLD, whereas the most complex causes of subsidence are found in the southeast of the city, as the newly built-up areas interact with the rock type and FLLD to form a complex subsidence regime. Those areas also show the highest subsidence values among all other parts of the city. The accuracy of the final model was confirmed using linear regression analysis, with an R2 value of 0.88.

This study aims to analyse the effect of tax services, tax amnesty, taxation knowledge, and tax sactions on taxpayer compliance. The population in the study is an individual taxpayer in the city of Yogyakarta. The sample in the study was an individual taxpayer in the city of Yogyakarta, and took part in the tax amnesty program. The sampling technique in this study used the convenience sampling method. Responden in the study amounted 60 respondents. The data anlysis technique in this study used multiple linear regression analysis. This study obtained result that taxpayer compliance in influenced by tax services and tax amnesty programs. However, taxation knowledge and tax saction does not affect taxpayer compliance. The cause of taxation knowledge does not affest taxpayer compliance, perhaps the understanding of taxpayers regarding the procedures for payment and reporting is still minimal. Meanwhile, the reason for lack of support fot tax sanction on taxpayer compliance, perhaps because taxpayers consider that saction given when taxpayer violate laws are still mild. Therefore, these two reasons are factors that encourage taxpayers to behave disobediently.

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.

The fast development of urbanization has led to imbalances in cities, causing congestion, pollution, and urban sprawl. In response to the growing concern over the distribution of demand and supply, a more coordinated urban structure is addressed in comprehensive planning processes. In this study, we attempt to identify urban structure using a Network–Activity–Human model under the Transit-Oriented Development (TOD) concept, since TOD is usually regarded as an urban spatial planning tool. In order to explore the strengths and weaknesses of the urban structure, we define the TOD index and unbalance degree and then classify the urban areas accordingly. We take the city of Beijing as a case study and identify nine urban types. The results show a hierarchical urban structure: the city center covers most of the hotspots which display higher imbalances, the surroundings of the city center are less developed, and the city edges show higher potentials in both exploitation and transportation development. Moreover, we discuss the extent to which the spatial scale influences the unbalance degree and apply a sensitivity analysis based on the goals of different stakeholders. This methodology could be utilized at any study scale and in any situation, and the results could offer suggestions for more accurate urban planning, strengthening the relationship between TOD and spatial organization.

Reliability is cited as a key aspect of service quality, but many of the indicators in use today do not measure reliability from the user's perspective. A review of earlier work on transit user behavior concluded that the traveler's perspective of reliability was driven by punctuality in arriving at the destination, short waiting times at the origin stop, and consistent wait and travel times. Twenty indicators were assessed, but none were well suited to capturing all of these elements of reliability. A new measure, journey time buffer index (JTBI), was therefore proposed; the index used estimates of wait times at bus stops while capturing variability in wait and travel times that tended to increase the disutility of transit travel. Alternative formulations were developed for short and long headway service, and the new indicator was applied to the London Transit Commission's bus network in London, Ontario, Canada. This procedure demonstrated that the JTBI was better suited to identifying the factors contributing to unreliable service than metrics that focused on a single component of reliability. A linear regression analysis also highlighted that route length, stop spacing, time of day, route orientation relative to the city center, and passenger load all influenced reliability although the low adjusted R2 value of .298 showed that some major causes of reliability were not captured by the model.
