Abstract:Like the rest of the country, Louisiana has made great strides in reducing the number of
crashes, particularly fatal crashes in recent years. Over the past three years, traffi c fatalities
were reduced from 915 in 2008 to 720 in 2010. However, Louisiana’s fatal crash rate of 1.58
[fatalities per 100 million vehicle miles traveled (VMT)] is still higher than the national average
of 1.02. To further improve roadway safety in Louisiana, eff orts must be made in reducing the
number of lane-departure crashes because this type of crash still accounts for nearly 20% of
crashes in the state. Edge line implementation has been considered as one of most promising
lane-departure crash countermeasures.
