South Carolina DOT Tree Removal Noteworthy Practices HereвЂ™s where to find information about the FHWA's involvement with CSS. The FHWA and Context Sensitive Solutions (CSS) This web site is the transportation community's online resource center for Context Sensitive Solutions (CSS). This research study conducted for Caltrans looked at median collisions, and found that there was a significant association between crash severity and the presence of large trees. Investigations of Median Trees and Collisions This guide focuses on measures that can mitigate impacts of tree crashes.Д¬ollisions With Trees One-Pager This tri-fold brochure presents an overview of issues related to trees and highway safety, and tells where to find more information.ДЄ Guide for Addressing Collisions with Trees in Hazardous Locations ДЄ Guide for Addressing Collisions with Trees in Hazardous Locations is Volume 3 of NCHRP Report 500: Guidance for Implementation of the AASHTO Strategic Highway Safety Plan.

This 12-minute DVD produced by the FHWA encourages communities to work with roadway agencies to improve safety, while minimizing environmental impacts. Trees are the single most commonly struck objects in roadside crashes. These practices range from complex, multi-million dollar contract solutions to in-house practicesДVD: Highway Safety and Trees: The Delicate Balance This report provides agencies with examples of successfulвЂ“immediately deployableвЂ“tree and pole practices.

Return to top Trees and Landscaping Considerations This page provides additional clarification on the design of clear zones and the distinction between clear zone and horizontal clearance. On roads posted at speeds 45 mph or lower, the breakaway criterion may be met when upgrading sign retroreflectivity.Д¬lear Zone and Horizontal Clearance Frequently Asked Questions

Existing sign supports located on highways posted at 50 mph or greater shall meet this criterion by January 10, 2013. All new sign installations shall meet these criteria. The MUTCD requires that sign supports within the clear zone be made breakaway or shielded by a barrier.

Manual on Uniform Traffic Control Devices For horizontal curves the clear zone can be increased by up to 50 percent from these figures. For steeper slopes on a 70 mph roadway the clear zone range increases to 38 to 46 feet, and on a low speed, low volume roadway the clear zone range drops to 7 to 10 feet. The recommended clear zone ranges are based on a width of 30 to 32 feet for flat, level terrain adjacent to a straight section of a 60mph highway with an average daily traffic of 6000 vehicles. This document provides guidance to help highway agencies develop their own standards and policies for determining the widths of clear zones along roadways based on speed, traffic volume, roadside slope and curvature. However, the minimum 18 inch horizontal clearance to vertical obstructions must still be met unless a design exception is approved. It is recognized that providing a clear zone as recommended in the RDG may not be practical in low speed curbed facilities because of right-of-way constraints and other realities of the built environment and a design exception is not required in these cases. The recommended clear zones in the AASHTO Roadside Design Guide (RDG) are based on the design speed of the facility and the slope of the roadside and are not affected by the presence of curbs. Because curbs do not deter errant vehicles from leaving the traveled way, the minimum horizontal clearance does not provide a clear zone sufficient to accommodate errant vehicles. The minimum 18 inch horizontal clearance to objects behind curbs that is specified in the AASHTO Green Book is a minimum standard offset that allows for normal traffic operations. Horizontal вЂclearanceвЂ™ must not be confused with вЂclear zoneвЂ™. Clear roadsides consider both fixed objects and terrain that may cause vehicles to rollover. Key factors in assessing risk include traffic volumes, speeds, and slopes. The width of the clear zone should be based on risk (also called exposure).

By creating Clear Zones, roadway agencies can increase the likelihood that a roadway departure results in a safe recovery rather than a crash, and mitigate the severity of crashes that do occur.ДЄ Clear Zone is an unobstructed, traversable roadside area that allows a driver to stop safely, or regain control of a vehicle that has left the roadway.
