Model for the Substantiation of Road Safety Improvement Measures on the Roads of Lithuania

Abstract

This article gives the summary of the author’s PhD Thesis supervised by Prof Dr Donatas Čygas and defended on 16 December 2009 at the Vilnius Gediminas Technical University. The thesis is written in Lithuanian and is available from the author upon request. Chapter 1 gives the main data on the road network of national significance of Lithuania, the change in the level of vehicle ownership, the basic accident indices and the essential factors influencing road safety. Chapter 2 gives a review of research methods used, review and evaluation of methodologies for the substantiation of road safety measures in Lithuania, Finland, Belarus, Poland and Sweden. Chapter 3 gives the evaluation of the effect of road safety measures implemented on the roads of Lithuania in 1999−2002. Chapter 4 describes the improved model for the substantiation of road safety measures under Lithuanian conditions. Chapter 5 presents the use of mathematical models for the forecasting of road accidents on the main roads of the Republic of Lithuania.
