ENG09017 2016 Road and Transport Scheme Design
Module topics relate to road geometrical design and transport demand study modelling, including the fundamentals of horizontal/vertical alignment, sight distance/visibility, design speed, road cross-sections, junction design and traffic demand predictive modelling. The module also reflects current design standards, including TII/NRA DMRB, DMURS and National Cycle Manual,to incorporate the needs of vulnerable users, active travel modes and sustainable travel principles. These are integrated into the technical design process to provide holistic, integrated, and safe network designs in both urban and rural environments. The design of non-motorised (cycle/pedestrian networks), bus rapid transit (BRT), and light rail transit systems extend the focus beyond public road schemes to include active and public transport facility provision. The inclusion of road restraint systems, rural and urban roadside feature design, minor improvement schemes, and design elements for traffic calming and pedestrian/cycle crossings is also a feature. An understanding of the implications of BIM and other 3D design software will also be included.
On completion of this module the learner will/should be able to;
Assess, evaluate and formulate the components of travel demand data analysis, forecasting and modelling to determine trip generation, distribution, modal split and assignment attributes for urban and regional studies as an input to the road and transport scheme design process.
Evaluate and apply the fundamentals of traffic flow, queuing theory and highway design capacity.
Design and specify road geometry, cross-section and co-ordinated link design to meet the needs of all users.
Critically assess, determine and review the needs and requirements for road junction options and design characteristics to meet the needs of all road users.
Design and formulate the components of integrated rural and urban road networks including road restraint and safety systems, and integration of vehicular and active and sustainable travel modes with the rural and urban road network and transport network.
Teaching and Learning Strategies
The teaching and learning strategy is based on the provision of on-line lectures, tutorials and group workshops that incorporate elements of enquiry, group, and project-based learning.
Module Assessment Strategies
A blend of final written examination and continuous assessment projects. The learner must achieve a grade of 40% or higher in order to achieve a pass in this module

ISBN 1118378156 ISBN-13 9781118378151
The repair, renovation and replacement of highway infrastructure, along with the provision of new highways, is a core element of civil engineering, so this book covers basic theory and practice in sufficient depth to provide a solid grounding to students of civil engineering and trainee practitioners.
- Moves in a logical sequence from the planning and economic justification for a highway, through the geometric design and traffic analysis of highway links and intersections, to the design and maintenance of both flexible and rigid pavements
- Covers geometric alignment of highways, junction and pavement design, structural design and pavement maintenance
- Includes detailed discussions of traffic analysis and the economic appraisal of projects
- Makes frequent reference to the Department of Transports Design Manual for Roads and Bridges
- Places the provision of roads and motorways in context by introducing the economic, political, social and administrative dimensions of the subject

ISBN 1845640977 ISBN-13 9781845640972
Currently there is no single textbook that addresses the fundamental geometric concepts of urban and rural road design. Traffic behavior has significantly changed over the last two decades and warrants newer methods for road design. Unlike the advances made in building, ship and aircraft design, road design is still carried out in a traditional way which is more than fifty years old. Starting from the traditional design process this book introduces a 3-dimensional geometric design process of urban and rural road design. It will prove to be a valuable textbook for undergraduate and graduate university students as well as road planning and design practitioners.
2015-09-09 Highway Engineering: Planning, Design, and Operations Butterworth-Heinemann
This book helps readers maximize effectiveness in all facets of highway engineering including planning, design, operations, safety, and geotechnical engineering. Highway Engineering: Planning, Design, and Operations features a seven part treatment, beginning with a clear and rigorous exposition of highway engineering concepts. These include project development, and the relationship between planning, operations, safety, and highway types (functional classification). Planning concepts and a four-step process overview are covered, along with trip generation, equations versus rates, trip distribution, and shortest path models equations versus rates. This is followed by parts concerning applications for horizontal and vertical alignment, highway geometric design, traffic operations, traffic safety, and civil engineering topics.
- Covers traffic flow relationships and traffic impact analysis, collision analysis, road safety audits, advisory speeds
- Applications for horizontal and vertical alignment, highway geometric design, traffic operations, traffic safety, civil engineering topics
- Engineering considerations for highway planning design and construction are included, such as hydraulics, geotechnical engineering, and structural engineering
