Abstract

This article presents methods of accident rate and accident frequency that can be used to analyze dangerous road sections on all state main roads of Latvia. The authors note that evaluation of road traffic safety level may be done using several methods. Latvia has 15 state main roads which lead through 24 out of 26 districts, and their total length in Latvia is 1740.8 km. Analysis of road traffic accident statistics was carried out basing on the data available at Road Traffic Safety Directorate for a three year time period (2005–2007). The authors calculated the critical value of accident rate for the state main roads network, determining that its numerical value is 1.81 accidents per 106 vehicle km. They conclude that the relation between traffic intensity and accident rate for the state main road network of Latvia has been achieved.
