Although, like the rest of the country, Louisiana has made great strides in reducing the number of crashes, particularly fatal crashes, in recent years, our fatal crash rate of 1.56 is still higher than the national average of 1.10 in 2010. The vision of Louisiana Strategic Highway Safety Plan (LSHSP) is to reach Destination Zero Deaths on Louisiana roadways, which calls to cut the fatalities by half by 2030. To reach such a hefty goal, a list of actions is proposed aiming to reduce crashes and crash severities in all 4E aspects: engineering, education, enforcement, and emergency service. As it has been long recognized, the effectiveness of a crash countermeasure may vary from state to state because of the differences in road user behavior and travel environment, as well as the quality and sources of research used to determine the crash reduction factor (CRF). Not all CRFs listed in the FHWA desktop references clearly related to particular situations in Louisiana. There is a need to compile and present crash countermeasures in a way that would make it easier for LADOTD engineers and planners to apply a CRF for a given situation. |
