I can suggest some widely recognized and respected resources that can serve as a good starting point for road conception:
AASHTO Green Book: The "A Policy on Geometric Design of Highways and Streets" by the American Association of State Highway and Transportation Officials (AASHTO), commonly referred to as the AASHTO Green Book, is a comprehensive guide for the geometric design of transportation facilities, including roads and highways. It is a widely recognized and used resource in the United States.
ITE (Institute of Transportation Engineers) Manuals: ITE publishes various manuals and guides related to transportation engineering and road design. The "ITE Transportation Planning Handbook" and "ITE Traffic Engineering Handbook" are valuable resources for professionals in the field.
FHWA Design Manuals: The U.S. Federal Highway Administration (FHWA) provides design manuals and guides on various aspects of road and highway design. Their publications cover topics such as roadway design, intersection design, and more.
International Road Assessment Programme (iRAP): iRAP offers resources and tools for road safety assessment and design. Their materials can help you design roads with a strong focus on safety and reducing road traffic injuries.
Local Design Standards: Depending on your specific project and location, it's important to consult the relevant local or state/provincial design standards and guidelines. These will often have specific requirements and considerations tailored to the local environment and regulations.
Design Software and Tools: Utilize specialized design software, such as AutoCAD Civil 3D or Bentley MXROAD, for road design. These tools can help you create accurate and efficient road designs.
Consult with Experts: If you're working on a significant road design project, consider consulting with experienced transportation engineers or firms with a proven track record in road design. They can provide valuable insights and guidance. Thank you
As the developing world witnesses a boom in road building, a movement to retrofit existing roads is gathering steam. Using embankments, channels, and dikes, so-called “green roads” help control floods, harvest excess water for use in irrigation, and slash maintenance costs...
