Title of publication
analysis of pedestrian and bicycle accidents on pedestrian crossings on highways
in Uusimaa, Kanta-Häme and Päijät-Häme regions during 2007-2011
Abstract
A pedestrian crossing should be a safe place for pedestrians. However, there are about 700-800 crosswalk accidents per year in Finland.
Ten percent of these accidents occur on roads in rural areas. The aim of this thesis was to study how and why accidents occur on pedestrian
crossings on roads, and how pedestrian crossings could be improved.
The literature review focused on the national regulations of the construction of cross-walks, road rules and traffic behavior. Based on the
limited available literature, the most significant contributing factors to accidents were speed, lack of knowledge of traffic rules and failure
to comply with road rules.
The empirical data consisted of police reports and measurements and observations done on field visits to selected accident sites. In the
first phase, the accidents were divided into three categories. The classification was based on accident type, activities of the in-volved persons
and traffic environment. The data showed that the accidents happened mainly due to the lack of foresight, and because the parties
had not noticed each other before the accident.
In the second phase of the empirical analysis field visits were made to about 30 percent of all of accident sites. Field visits were used
to assess the traffic environment, and how it may have contributed to a lack of foresight. It was found that the gradient of the light traffic
route should not exceed 8 %, as this might form a sight obstacle. Other important findings were the deficiencies in crosswalk markings.
Such deficiencies were poor plac-ing of crossing sings and the poor condition of road markings.
The main suggestions for improving the crosswalks were to improve the detectability, clarification of traffic rules with traffic control and
changes in traffic light control phas-es. Road safety attitudes can be influenced by information and control as well as by a safe traffic
environment.
