Specific Scale

Accessibility is fundamentally thought to be related to functional, economic, and social performances of cities and geographical systems and, therefore, constitutes an essential aspect for spatial planning. Previous studies focused on cities or metropolitan scales, often disregarding their position within regional and national systems, which can greatly affect their performance. Although accessibility at various spatial scales has been examined, the studies focused on accessibility patterns at different scales, with no reference to the level of accessibility of cities over local, regional, and national scales simultaneously, i.e. multiscale accessibility. This study aims to elucidate the multiscale accessibility level of individual cities and examine its relationship to urban performance in the urban system of Israel. Spatial accessibility was analyzed using the space syntax methodology for the entire national road network across multiple geographic scales—from the local to the national scale. Based on three distinct spatial accessibility systems identified, a unique multiscale accessibility profile was created for individual cities in Israel. Subsequently, each city’s multiscale accessibility profiles were examined against urban performance indicators determined from urban scaling theory. We found that the superiority of cities characterized by high accessibility level plays a role not only for a specific scale but also over scales and spatial systems. Moreover, most urban performance indicators related to the multiscale accessibility profiles of cities, while some multiscale accessibility profiles can be related to over- or under-performance of cities. The findings suggest that pervasive accessibility across spatial scales is inherently connected to urban performance and may indicate on the implementation and interpretation of accessibility. These findings may assist in various aspects of spatial planning at various scales.

Abstract. Several publications of the European Spatial Planning Observation Network (ESPON) suggest that one should be aiming at a polycentric urban system, albeit one which does not unambiguously display properties of territorial development (Vandermotten 2003). Focusing on concentration processes and implications of urban policies, the article draws attention to those regional processes (topographic) and urban networks (topologic) destined to play the double role of catalyst and diffuser of innovations in a diversified European territory. It is argued that various spatial scales and a range of different perceptions of polycentrism be taken into consideration. It is felt that only through the articulation of these differences will the relevant processes and networks be able to function optimally within a context where the interrelations of urban governance are adapted to each territory.

The processes of technological  progress create new opportunities for economic, social and cultural growth, shape new relations between economic  entities and their environment,  and influence changes in the determinants  of entrepreneurship development.  These processes vary significantly in certain geographic locations, characterised by an enormous  diversity of natural, social, economic and cultural structures. As a consequence, this creates different opportunities  and different conditions for the development of entrepreneurship in certain spatial scales, from the continental scale, through national and regional to local scales. The article presents complex conditions  for the development of entrepreneurship, highlights its limitations resulting from institutional  barriers, and the importance of knowing the mechanisms of mutual relations between spatial systems and the influence of control instruments. The quality of central and local government authorities is of particular significance here, which do not always properly use the mechanisms of rational business support. A serious barrier to the development of entrepreneurship is the low quality of social capital, manifested in a lack of trust in institutional authorities and reluctance to engage in entrepreneurship and business development. The conclusions point out that further research should be developed that will take into account changing business conditions, with a defined strategic goal of raising the quality and standard of living, international competitiveness of the country and products in different market categories.

In recent decades, the environmental issue has led to greater flexibility of spatial scales, using an environmental discourse to intervene on the ground. The State has been organising this space, using the environmental issue as justification, with specific laws containing spatial planning objectives, as well as allowing municipalities to carry out direct action in their territories to deal with the most urgent issues relating to land management. At the same time, as has happened with policy changes since the 1990s, public power has established territorial strategic alliances with the private sector in a way which has mainly favoured the latter. This article aims to show how this issue is dealt with in the Green Municipalities Program, which began in Southeast Pará in 2008. The results show a process of re-harnessing the economic value of the space using the discourse of "sustainable development".

Abstract Geoweb methods offer an alternative to commonly used public participation methods in spatial planning. This paper discusses two such geoweb methods – geo-questionnaire and geo-discussion in the context of their initial applications within the spatial planning processes in Poland. The paper presents legal and organizational framework for the implementation of methods, provides their development details, and assesses insights gained from their deployment in the context of spatial planning in Poland. The analysed case studies encompass different spatial scales ranging from major cities in Poland (Poznań and Łódź) to suburban municipalities (Rokietnica and Swarzędz in Poznań Agglomeration). The studies have been substantiated by interviews with urban planners and local authorities on the use and value of Geoweb methods in public consultations.

The concept of ‘resilience’ breaks down silos by providing a ‘conceptual umbrella’ under which different disciplines come together to tackle complex problems with more holistic interventions. Acknowledging the complexity of Davoudi’s approach (2012) means to recognize that ‘spatial resilience’ is influenced by many phenomena that are difficult to measure: the adaptation and transformation of a co-evolutive system. This paper introduces a pioneering approach that is propaedeutic to the spatial measure of urban resilience assuming that it is possible to define a system as being intrinsically vulnerable to stress and shocks and minimally resilient, as described by Folke in 2006. In this sense, vulnerability is counterpoised to resilience, even if they act simultaneously: the first includes the exposure to a specific hazard, whereas the second emerges from the characteristics of a complex socio-ecological and technical system. Here we present a Geographic Information System-based vulnerability matrix performed in ESRI ArcGIS 10.6 environment as an output of the spatial interaction between sensitivities, shocks, and linear pressures of the urban system. The vulnerability is the first step of measuring the resilience of the system by a semi-quantitative approach. The spatial interaction of these measures is useful to define the interventions essential to designing and building the adaptation of the built environment by planning governance. Results demonstrate how mapping resilience aids the spatial planning decision-making processes, indicating where and what interventions are necessary to adapt and transform the system.

Abstract In Romania, with time, settlements located along the main roads have developed and transformed into linear towns, with significant local and connection traffic, important administrative, economic, commercial and touristic activities concentrated in the central area, as well as pedestrian traffic of over 200 pedestrians per hour in the main pedestrian crossings on the route. The object of the present study is made by a series of junctions situated on National Road 1 in Busteni town, on a dangerous road sector. For this study, traffic measurements, simulations and suggestions for improving the existing situation were made. Based on the simulated traffic flows, there were performed capacity analysis with PTV Vissim and Traficware Synchro softwares, and were developed appropriate planning solutions for the intersections, resulting in tables with extracted performance indicators based on micro simulation of the traffic values. Also planning solutions for horizontal design and proposals for traffic lights were made for junctions that can not operate under priority traffic on one direction or which are presenting traffic safety risk. Based on the traffic data, it was taken in consideration the necessity to make planning proposals and to develop design solutions immediately applicable, with minimum intervention. Solutions will refer to the geometric planning of the intersections, but with new plans and timings for traffic lights, including proposals for new equipment; regulating the traffic flow: development/ refurbishment of intersections and pedestrian crossings; optimization of routing programs in order to achieve a higher level of service and more efficient traffic control indicators; segregation of pedestrian movements by vehicles traffic, implementation of physical devices to lock / channel the traffic.

Abstract Expansion of the wildland-urban interface in countries in the European Mediterranean basin is increasing vulnerability to forest fires. Despite more effective extinction systems, this is still a growing problem. This article defends the importance of spatial planning (land-use and urban planning) and the need for systematic intervention to mitigate this wildfire risk. A critical review of the current situation, noting intervention focused on buildings and plots and insufficient action on intermediate spatial scales, is followed by the presentation of significant and relevant experiences in the European context.

The significance of the regional disproportions at the territory of Serbia, when it comes to demographic resources, imposes in front of the social community a task for public policy measures to be more efficient and more precisely addressed towards the local communities where the limit of their possible acting has not been perturbated yet. Thus, defining of coherent public policies requires good research of the demographic processes and problems on all levels and defining developmental solutions in accordance with them. Dimensioning of demographic potentials is one of the challenges and priorities of spatial planning as well, as a controlling instrument that has been gaining significance in modern conditions. Foreign experience in this field, i.e. the system of spatial planning in European countries, with the special attention paid to the ways of solving problems connected to demographic processes and appearances, is undoubtedly instructive for the domestic practice and the establishment of public policies on state and lower regional levels. Given the fact that the inequality in development is caused, above all, by the expressive metroplization and polarization of the Serbian territory, in modern conditions it is considered that the application of the polycentric development model could help avoiding further excessive economic and demographic concentration. It includes economic competitiveness and social equality (sustainable development) as pre-requisites for the diminishing of local disparities to the acceptable minimum. In that sense, it is considered that a group of middle sized towns represents a pivot in establishing homogeneous national urban system which would lead to the increase in the degree of settlement network consistency. It is necessary that the endeavour to decentralize Serbia be elaborated with concrete measures and instruments that would route further state development, meaning affirmation of the middle sized towns.

Abstract The uneven spatial distribution of basic facilities within urban areas is a major problem for developing countries like Senegal due to the emphasis of accessibility disparities and the use of this services. The efforts to quantify the problem and its consequences on people are constrained by the lack of satisfactory data and methods. The study seeks to examine the spatial accessibility to basic services (access to water, health, education, economic infrastructure and transportation services) in a very heterogeneous urban system and to highlight inequalities in access for improving the geographical accessibility and to ensure equity. The article explore the use of spatial analysis method (Closest Facility) to measure the potential accessibility to services and facilities in the city of Mbour. The analyses uses all the inhabited houses of the city as the potential demand. Results emphasis unequal access to basic urban services in the city and a center-periphery model with a high concentration of services around the city. The study demonstrates the utility of this method for the identification of disadvantaged areas, decision making and planning of basic services. It also provides paths for improving accessibility in urban areas with a high density of population.

Since the presentation of the radiation model, much work has been done to compare its findings with those obtained from gravitational models. These comparisons always aim at measuring the accuracy with which the models reproduce the mobility described by origin–destination matrices. This has been done at different spatial scales using different datasets, and several versions of the models have been proposed to adjust to various spatial systems. However, the models, to our knowledge, have never been compared with respect to policy testing scenarios. For this reason, here we use the models to analyse the impact of the introduction of a new transportation network, a bus rapid transport system, in the city of Teresina in Brazil. We do this by measuring the estimated variation in the trip distribution, and formulate an accessibility to employment indicator for the different zones of the city. By comparing the results obtained with the two approaches, we are able to not only better assess the goodness of fit and the impact of this intervention, but also understand reasons for the systematic similarities and differences in their predictions.
