How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Łukasz Kowalski currently worked at the Institute of Geography and Spatial Management, Jagiellonian University. Łukasz does research in Economic Geography, Geoinformatics (GIS) and Geography. Their most recent publication is 'Modelowanie optymalnej lokalizacji dla działalności sportowo-rekreacyjnej w regionie miejskim Krakowa (en. Modelling the best location for sport facilities in the region of Krakow)'.
Aggregated models, such as spatial interaction (SIM) models are widely used in location analysis. Despite their popularity, there are certain limitations to their use. In particular, the method struggles to account for the passing-by population and multi-purpose trips of retail clients, temporal changes in accessibility and some bottom-up processes...
Raport jest wynikiem analiz danych zebranych od krakowskich rowerzystów w ramach badania pt. AnkietaRowerowa.pl. Poprzez stronę internetową oraz aplikację mieszkańcy Krakowa mieli możliwość podzielenia się swoją wiedzą oraz doświadczeniami związanymi z infrastrukturą rowerową. W efekcie udało się skonstruować ogromną bazę danych o preferencjach kra...
By 2050, world’s urban population will reach 6,3 billion. This growth will force cities to use their water, energy, transportation systems more effectively. This will lead to the development based on innovation, collaboration and information, which is part of intelligent city concept and, more and more often, concept of sustainable city. The purpos...
Management and development of bicycle network is a challenge for big Polish cities. Sufficient data about cyclists, their daily trips and problems is lacking. The authors used internet survey to map places perceived by cyclists as problematic. During 2 months 532 persons have responded, mapping 1 235 spots and 1 140 sections requiring repairing and...
In 2010 only about 50% of children aged 3–6 years in Małopolska region attended kindergartens. Such low index is to some extent an effect of the supply-demand mismatch. The problem becomes even more vital in the context of recent changes in education law. The introduction of obligatory attendance to kindergartens for 5-years-old and postponement of...
The purpose of this article is to present and analyse the results of surveys carried out on cyclists in Krakow in 2013, authors also suggested the possibility of their use and the future direction of research. Authors analysed 1600 questionnaires, filled up mainly through the Internet. Three types of cyclists were distinguished: all year-commute, s...
It is an English version of questionnaire hat I used in my survey at swimming pools, fitness clubs and yoga schools for my research for my Ph.D. thesis.
The aim of the paper is to discover in which order new sections of Cracow cycle route network shall be built. The authors created a location model based on gravity model. Potential flows between homes and city centre, workplaces, secondary schools and universities were considered. Exponential function was applied as distance-decay function. Moreove...
Summary: The purpose of this article is to propose a research tool which would allow to understand profound and rapidly public space in small towns with its local specifics. The tool is designed for outside experts (“strangers” in analyzed area) involved in the preparation of strategic and planning documents for towns and is combined of three metho...
In this master thesis author has dealt with the sport in the Urban space of Krakow. The author’s aim was to analyse a significance of sport for city’s inhabitants, conditions of sport objects’ location and spatial accessibility to sport infrastructure. The distribution of the sport should be related to the distribution of population. Author analyse...
I need to make a survey in sport clubs like fitness, yoga, tennis, squash and swimming pools about participants' perception of their club's location. I'll make the research in a big (almost 1 mln) city.
Later on I would like to combine results with an agent based model (ABM) - get characteristics of participants and put in my ABM.
The best scenario would be to have a representative random sample, but it is impossible to get a full list of participants (sampling frame). There are only lists for fitness clubs and none for the others. Some of them come only occasionally.
Do you think it would be reasonable to randomly, proportionally choose sport clubs, regarding their type, later on randomly select hours of activities performed and make a survey with everyone who came at certain hour.
Would it give representative opinion for all participants? And could I then count a sampling error and confidence interval? How could I improve representativeness here?
I am also wondering how big my sample should be? Is 1000 questionaries enough? In fact I don't know how many participants are in those clubs. The only thing I could use here are quite new results of national survey - I can get characteristics of sport participants.
I would be grateful for any help.
I write my PH.D.thesis about finding the best location for sport facilities in Krakow region, Poland. It is based on findings from my survey in Krakow's clubs. I use spatial interaction model and agent-based model to find best sites. When I finish my models will be ready to support location decisions in big cities' agglomeration, like Krakow.
