(5) Barrier Wall SystemsĬoncrete barrier walls and guardrails prevent drivers from crossing into opposing lanes throughout the length of the installation. It should be noted that median treatments meeting the requirements of Appendix A of 49 CFR Part 222 are considered supplemental safety measures by FRA for use in a quiet zone (see Quiet Zones). The median should be designed to allow vehicles to make left turns or U-turns through the median where appropriate, based on engineering judgment and evaluation. Medians and traffic channelizing devices need to be kept out of the path of turning vehicles to avoid being struck. The benefits of installing channelization should be considered along with possible adverse effects on local access and circulation as well as the potential for a road user to strike the barrier. In addition to discouraging crossing gate evasion, such treatments may be used to restrict left-turns across the median to and from driveways or minor streets adjacent to the crossing thus reducing conflicting vehicular turning movements in the crossing vicinity.
Various styles of median treatments include barrier wall systems, wide raised medians, and mountable raised curb systems. Highway authorities have implemented various median separation devices, which have shown a significant reduction in the number of vehicle violations at crossing gates. The number of crossing gate violations can be reduced by restricting driver access to the opposing lanes.
