The purpose of this paper is placed on improving the expressway safety through identifying the causes and characteristics of expressway accidents and suggesting the safety countermeasures.
Even though expressway accidents per MVK (Million Vehicle Kilometers of Travel) have decreased from 1.96 in 1970 to 1.27 in 1981, the toll of lives lost, persons injured, and economic loss are still so great as to represent one of today’s major social problems.
In order to identify the causes and characteristics of expressway accidents, expressway accidents are studied as follows: 1) General analyses including accident analysis by cause, 2) Seasonal variation analysis of time-series for the year 1978 through 1981 and accident analysis by hour compared with traffic volume by vehicle type, 3) Control chart analysis for 43 sections to identify 'out of control' sections, and 4) Regression analysis of factors contributing to accident rate, such as average speed, variance of speed between vehicle types, the proportion of vertical alinement more than 3%, the proportion of curve radius less than 500m, and traffic density (ADT/Km).
And 7 objectives are set in order to suggest the safety countermeasures divided into 17 items having priority.
In conclusion, a comprehensive safety program including major facilities investment should be made in order to ensure expressway safety.
