Investigation of the consequences of the modifiable areal unit problem in macroscopic traffic safety analysis: A case study accounting for scale and …
2019
Abstract Traffic safety analysis at the macroscopic level usually relies on previously defined areal traffic analysis zones (TAZs) that are used as the units of investigation. Hence, statistical inference is made on the basis of such units, implying that the consideration of a certain TAZ configuration may influence the results and conclusions achieved. Regarding this, the modifiable areal unit problem (MAUP) is a well-known issue in the field of spatial statistics, which refers to the effects that arise in statistical properties and estimations when there is a change in areal units of analysis. In this paper, the consequences of MAUP have been investigated through a dataset of traffic cras…
Dasymetric distribution of votes in a dense city
2017
[EN] A large proportion of electoral analyses using geography are performed on a small area basis, such as polling units. Unfortunately, polling units are frequently redrawn, provoking breaks in their data series. Previous electoral results play a key role in many analyses. They are used by political party workers and journalists to present quick assessments of outcomes, by political scientists and electoral geographers to perform detailed scrutinizes and by pollsters and forecasters to anticipate electoral results. In this paper, we study to what extent more complex geographical approaches (based on a proper location of electors on the territory using dasymetric techniques) are of value in…
QUANTITATIVE ANALYSIS OF SPATIAL INDICATORS IN THE CASE OF VARYING ADMINISTRATIVE BOUNDARIES
2021
The aim of the research is to develop methods that would allow comparingthe statistical parameters of Latviaat differing administrative divisions, thereby solvingthe problems that arise in the case of discrepancy of borders. As part of thework, the developed method was implemented in order to assess the suitabilityof the created tool for mathematical analysis of statistical parameters on Latvia. Theterritory examined in the work is Latvia; the discrepancy of borderswas examined by comparing the parish borders of 1935 with the parishes of 2000.Therefore it was necessary to create a transfer matrix in order to link theadministrative borders of both periods. The transfer matrix was prepared in…
Spatial Vote Redistribution in Redrawn Polling Units
2012
Summary A large proportion of electoral analyses using geography are performed on a small area basis. In each new election there are always modifications to the previously existing polling units. The use of past voting results in small area aggregate data electoral forecasting models and political analyses therefore requires establishing a correspondence between old and new polling units. Traditionally, the task of tracking changes to assign an electoral history to the new units properly has been carried out by hand, comparing unit codes and census figures. This is an extremely cumbersome task that cannot always be performed, as when a massive (geographically intense) reorganization of poll…
