Module Aim:
The aims of this module are to provide the students with a knowledge of
(a) analysis of traffic flow and preparation of traffic analysis reports;
(b) geometric layout design of roads and junctions;
(c) the materials used in bituminous pavements, relevant laboratory tests associated with these materials and the design of bituminous pavements.
Learning Outcomes
On successful completion of this module the learner should be able to:
LO1
Evaluate and analyse traffic flow and relate this to road/junction capacity and prepare a traffic analysis report. Select the appropriate number of lanes, lane widths and junction geometry for roads based on traffic flows.
LO2
Prepare a geometric design of a section of road and junction using 3D road design software.
LO3
Select appropriate bituminous pavement structures for vehicle loading and specify appropriate testing for these materials.
LO4
Demonstrate appropriate presenting, written and visual communication skills including writing reports, presentations and preparing drawings using 3D road design software.
