Geometric Road Design

Introduction:

This Geometric Road Design training program teaches the principles, standards, and techniques of designing road alignments and cross-sections by both the Egyptian Code for Road Works and AASHTO (American Association of State Highway and Transportation Officials). It includes instruction on horizontal and vertical alignment, cross-sectional elements, and safety considerations. Participants gain practical skills to create road designs that meet national and international regulatory standards and specific project needs.

Program Objectives:

At the end of this program, the participants will be able to: 

• Recognize the applications of horizontal and vertical alignment and road planning and design principles about both the Egyptian Code and AASHTO guidelines.

• Recognize the importance of road geometric design for safe roads, referencing safety standards from both Egyptian and AASHTO specifications.

• Conduct Road Safety Inspections (RSI) and base Road Safety Audits (RSA) according to relevant local (Egyptian) and international (AASHTO) methodologies.

• integrate the newest Intelligent Transportation Systems (ITS) design trends for roads, referencing guidelines and best practices from both codes.

• Create traffic simulations for the coordination of traffic signs and signals in compliance with Egyptian and AASHTO traffic control device requirements.

Targeted Audience:

• Road Engineers.

• Project Directors.

• Engineers in Transport.

• Strategic Development of Road Geometric Design Personnel.

• Participating Architects in Urban Design.

• Urban and Rural Planning Specialists.
