More specifically, accident severity depends on several factors related directly to the driver, i.e., driving experience, driver's socio-economic characteristics, and driving behavior and attitudes.
Other research found that higher speed limits increased the probability of a more severe accident and that accident severity increased outside level and straight roadways [21, 22].
Several other studies focused on traffic accident severity analysis using traditional statistical techniques and provide good results [4, 5, 6, 7, 8, 9, 10, 11, 12].

This research statistically studies the effectiveness of ice warning signs in reducing accident frequency and accident severity in Washington State.
In conventional risk studies, consequence assessment is carried out through simplified tools and conservative assumptions, often resulting in overestimation of accident severity and worst-case scenarios.
The design of conventional safety systems is based on failure likelihood and accident severity, which is normally obtained empirically, leaving the system vulnerable to process nonlinearities.
If the W-beam guardrail can withstand the higher impact angles, with only modest increases in accident severity, total accident costs can be reduced.
Only surface conditions and time of day are significantly correlated to bus accident severity.
When considering the approach to intersections, bus accident severity increases when bus drivers exhibit illegal behavior.
