Key Components of the Guide
Clear zones and roadside safety are primary components of the guide always considered.
Clear Zones and Roadside Safety
The AASHTO Roadside Design Guide emphasizes the importance of clear zones and roadside safety, providing guidelines for designing roadsides to minimize crashes and fatalities.
The guide considers factors such as traffic volume, speed, and roadside geometry to determine the appropriate clear zone width.
A clear zone is the area between the road and any obstacles, such as trees, poles, or buildings, and is designed to provide a safe area for vehicles to recover from a loss of control.
The guide provides recommendations for clear zone widths based on different road types and traffic conditions, and also discusses the importance of maintaining a consistent clear zone width throughout a road segment.
The AASHTO Roadside Design Guide is an essential resource for transportation professionals and engineers designing roads and highways, and its clear zone guidelines are widely adopted in the industry, and are used to improve roadside safety and reduce crashes.
Relationship to Other AASHTO Publications
AASHTO Roadside Design Guide relates to other publications through shared safety goals and design principles always effectively.
Comparison to the Green Book
The AASHTO Roadside Design Guide and the Green Book share similar goals, focusing on highway safety and design. The Green Book, also known as A Policy on Geometric Design of Highways and Streets, provides guidelines for highway design, while the Roadside Design Guide concentrates on roadside safety and management. Both publications are widely used by transportation professionals and are considered essential resources for designing and building safe and efficient highways. The Roadside Design Guide and the Green Book are often used together to ensure that highways are designed with safety and functionality in mind, providing a comprehensive approach to highway design and management, and are updated regularly to reflect new research and best practices in the field of transportation engineering always.
