Opis:: It is recognised in the literature that spatial accessibility is a measure of spatial equity and can be represented by the ease of travelling from an origin to a given destination via a given mode or set of transport modes. Although urban areas can benefit from improvements in accessibility when a new high-speed rail line is built, equity issues may arise. This manuscript describes a methodology for evaluating equity impacts due to an extension of the High Speed Rail network in Italy. A joint Revealed/Stated Preference survey has been carried out, collecting socioeconomic and travel data. Specifically, nine hypothetical scenarios have been submitted to Italian users aiming at understanding the motivations for not choosing the High Speed Rail as an alternative. The main outcome is that the access/egress travel costs connected with the High Speed Rail have a strong impact on spatial equity. The main policy implications of this study are that investors in high-speed rail should not only take into account the economic benefits brought by them, but also the spatial imbalance that these systems can bring.
È riconosciuto in letteratura che l'accessibilità spaziale è una misura di equità spaziale e può essere rappresentata dalla facilità di viaggiare da una origine ad una destinazione mediante un dato modo o insiemi di modi di trasporto. Anche se le aree urbane possono beneficiare di miglioramenti in materia di accessibilità, quando una nuova linea ferroviaria ad alta velocità viene costruita, potrebbero sorgere questioni di equità. Questo documento descrive una metodologia per valutare l'impatto sull’ equità connessa all’estensione della rete ferroviaria ad alta velocità in Italia. E’ stato effettuato un sondaggio sulle Preferenze Rivelate / Dichiarate, attraverso il quale sono stati collezionati dati socio-economici e di spostamento. In particolare, sono stati presentati agli utenti italiani nove scenari ipotetici volti a comprendere le motivazioni che li hanno indotti a non scegliere l'alternativa ferroviari ad alta velocità. Il risultato principale è risultato essere che i costi di accesso/egresso connessi al sistema ferroviario ad alta velocità hanno un forte impatto sull’equità spaziale. Le principali implicazioni politiche di questo studio sono che gli investitori in sistemi ferroviari ad alta velocità dovrebbero prendere in considerazione non solo i benefici economici portati da loro, ma anche lo squilibrio spaziale che questi sistemi possono portare.

Opis:: Public transportation plays a significant role in urban areas, transporting a large percentage of people. There is no existing study dealing with the balance between transportation demand and supply in Baghdad city; thus, there is a need to assess service equity before implementing any major services. The aim of the present research is to study the equity of transit need. The methodology uses geographic information systems (GISs) and spatial multi-criteria analysis to determine equity. Nine criteria were used in this study (land use, population density, commercial activities, medical locations, bus stops walkability, educational activities, bus terminal, and income) to determine a transit need map. Expert opinion surveys are conducted to determine pairwise comparisons between these criteria to estimate the weight of each criterion. Spatial analysis in ArcGIS 10.8 is utilized to apply methodology. The transit need map is obtained, and the need for transit service is represented by a value for each cell. In addition, the map output is important to public transit planning, as it maximizes the optimal transit route selection depending on the transit need. The output of this study (a transit need map) represents a powerful tool for the decision-makers to prioritize transportation programs and ranking alternatives. Gap analysis is used to measure equity between various zones. The results show that the transit supply provides higher service coverages in the Central Business District (CBD) and decreases as the distance to CBD increases.

Opis:: In the face of the numerous turbulence on the global financial markets the need for a more profound look at the phenomenon of volatility transfer between different markets increases because as a consequence of this phenomenon the increase in volatility in one market may lead to the appearance of an increased volatility on another. In the case of these relationships spatial displacement can also be observed, consisting in reactions of the market in one country on the changes taking place in other markets in other countries. In this approach, the analysis is carried out on the assumption that the markets are located in a metric space, where the relationship between the variables describing these markets are the functions of the physical or more likely economic distance between them. The aim of this article is to determine whether, in the context of the phenomenon of the price volatility transfer between different assets classes, a certain spatial relationships between them could be disclosured. Subsequently, in case of occurrence of supposed dependences, an attempt to identify the possible spatial relationships between the market in one country and markets located in the neighboring countries was made. To identify the spatial relationships dynamic spatial panel models were introduced. The research includes the markets of equities, bonds and foreign exchange markets representing selected countries in Europe and Asia in the period of 2000–2015.
W obliczu licznych turbulencji na globalnym rynku finansowym wzrasta potrzeba głębszego przyjrzenia się zjawisku przenoszenia zmienności, gdyż w jego konsekwencji wzrost zmienności na jednym rynku może prowadzić do pojawienia się podwyższonej zmienności na innym. W przypadku tych zależności istotne wydają się zwłaszcza przesunięcia przestrzenne przejawiające się w reakcjach danego rynku w jednym kraju na zmiany dokonujące się na tym rynku w innych krajach. W podejściu tym analizy przeprowadza się przy założeniu, że rynki są zlokalizowane w przestrzeni metrycznej, gdzie zależności między zmiennymi opisującymi te rynki są funkcjami fizycznej lub częściej ekonomicznej odległości między nimi. Celem artykułu jest sprawdzenie, czy w kontekście zjawiska przenoszenia zmienności między rynkami poszczególnych klas aktywów dochodzi do ujawnienia się pewnych związków przestrzennych między nimi. Identyfikacji ewentualnych zależności przestrzennych dokonano z wykorzystaniem dynamicznych panelowych modeli przestrzennych. Analizie poddano rynki akcji oraz dziesięcioletnich obligacji skarbowych reprezentujące wybrane kraje europejskie. Zakres czasowy badania objął lata 2000–2015.
