Method of classification of spatial units for transitrelated analyses

Transport activity may lead to multiple problems that decrease the quality of life of commuters. Among the many methods used to cope with these problems, considerable attention has been paid to the development of transit. Effective transit systems may encourage inhabitants to move away from the use of private cars to mass transport. It is therefore essential to identify the factors that contribute to high levels of ridership. Among such factors, land use mixture is often mentioned. However, it is unclear how it affects ridership. Therefore, to encourage further studies, it is important to develop methods of classification of spatial units in terms of land use mixture. Such analyses should be conducted for similar levels of transit supply. Hence, the aim of this paper was to develop a method of classification of spatial units in terms of land use mixture and transit supply. The method uses different characteristics of land use and transit supply as factors in the process of classification. The proposed method was used for an area in the city of Katowice to demonstrate its application.
