註釋Head-on crashes that occur on freeways are typically severe in nature and may be on the increase. A head-on crash typically occurs when a vehicle crosses the median and crashes with a vehicle traveling in the opposite direction (typically called a cross-median crash or median-crossover crash). A head-on crash can also occur when a vehicle inadvertently travels the wrong way in the opposing traffic lanes. Head-on cross-median crashes are typically the result of inadvertent actions by a driver potentially in combination with other adverse circumstances such as weather conditions or motorist fatigue. Recent experience and research has shown that a comprehensive approach to safety is most effective in creating a safer driving environment and improved effectiveness of safety treatments. A number of safety concerns including many related to head-on crashes cannot be as effectively solved by solely applying one of the four Es (engineering, education, enforcement, and emergency medical services) in isolation. When reviewing strategies dealing with head-on crashes, engineers should strongly consider the role of the other four E groups. To address the importance of considering a four E approach this document provides strategies that might be considered.
