CENV6171 Highway and Traffic Engineering

Module Overview

This module will provide you with a good knowledge and understanding of the fundamentals of road traffic flow and its analysis, using this as a basis for you to be able to undertake operational analysis and design of key features of the road transport system, particularly the design of the various types of road junction. You will also learn about the Highway Engineering process from its inception of planning and route location, through detailed geometric design and on to structural design, construction, condition monitoring, maintenance and eventual rehabilitation.

Aims and Objectives

Learning Outcomes

  • Traffic flow theory and traffic analysis processes on highways.
  • Analysis methods for traffic at road junctions
  • Designing for safety, efficiency and environmental protection.
  • Road junction types, layouts and operations.
  • Traffic control systems
  • The principles and practice of route location and geometric design of highways
  • The principles and practice of structural design for flexible, rigid and composite road pavements
  • Road condition monitoring and rehabilitation options/methods
  • Road construction and maintenance practices.
Subject Specific Intellectual and Research Skills

Having successfully completed this module you will be able to:

  • Select and design roads and junctions according to requirements/specifications
