In the United States there are more than one million kilometers of low-volume roads, generally defined as having an average daily traffic (ADT) of less than 400 vehicles per day. In Kansas there are several thousand kilometers of these low-volume roads. Widths generally range from less than 3 meters to 7 meters. These roads cross thousands of bridges and culverts that were built many years ago before any thought was given to 'forgiving roadsides,' and they have massive concrete bridgerails and culvert headwalls which are roadside obstacles that can contribute to serious crashes when vehicles stray from the roadway. A study was conducted by Kansas State University (KSU) to analyze the crash risk to vehicles hitting these concrete structures. The researchers used the computer software program ROADSIDE to compare the probabilities and expected cost of crashes at bridge and culvert locations with bridgerails and headwalls vs. the expected cost of crashes with bridgerails and culvert headwalls removed. It was concluded that the expected costs of these crashes were less with the concrete rails and headwalls removed for ditch depths of 2.4 meters or less. A detailed discussion of the analysis and results are presented.
