Evaluation of Distance Between Pedestrian Crossings by Students in One of the Polish Cities

Abstract

In this paper, the distances between pedestrian crossings in twenty one places in the city of Wrocław, together with their evaluation by the researched groups of students, were analyzed. The database created from the collected questionnaires contains a set of two-dimensional variables: the distance between crossings and the rating of the students. The database set was analyzed using a fuzzy data mining approach to create particular clusters. Various numbers of clusters were analyzed, and the division of data into three clusters made it possible to relate the analysis to the LOS methodology. Each variable was enriched with a third dimension representing a membership value. The obtained evaluated distances are similar to values recommended in literature, although the distances highly evaluated by the students do not often occur in reality. This might suggest that there is the need to create new crossings, especially in the city centre, where pedestrian trafic is or should be important.

The Perspective Projects Promoting Sustainable Mobility by Active Travel to School on the Example of the Southern Poland Region

“…However, in the case of taking actions in the educational policy, it is more related to the drivers' behavior when approaching places frequented by pedestrians. The estimated effects of enforcement by drivers yielding to pedestrians in crosswalks are shown by Sandt et al [88,89]. According to Pichayapan et al [90], sometimes reducing the number of road accidents in these places may be the result of minor modernization, such as crosswalk repainting, installing additional lighting to improve visibility, or the use of speed bumps, and additional information signs.…”
