Fuzzy regression approach to road safety analysis at regional level

Smolarek L., Wachnicka J.

Journal of Polish Safety and Reliability Association

2014

Vol. 5, No. 2

121--126

Road safety modelling on regional level of NUTS 2 in the EU is the complex issue ant authors of this article indicate this in previous publications. During multivariate models development they discovered that it is difficult to make regression model well described all regions, even if they are from one country. In the first step Poisson model of road fatality rate as fatalities per 100 thou of citizens was prepared. In this article was presented the fuzzy regression approach to estimate lover and upper bounds of the modeled value.
