[email protected] edu. au Course coordinator: Upali Vandebona INFORMATION ABOUT THE COURSE This is the first introductory course into the discipline of transport engineering as part of the broad field of civil and environmental engineering. An outline of the field of transport engineering and its relationships with other engineering and non-engineering disciplines is provided within the course. The basic concepts and terminology of the discipline is introduced. The course comprises of two strands. The first strand of the course covers the first 4 weeks of the session.

This strand is concerned with the analysis, design and evaluation of traffic and network systems, including basics of the four step transport planning process. The aim of this strand is to learn the basics related to methods applicable in transport planning and traffic engineering profession. The methods learned in this strand will be relevant in urban transport planning as well as regional planning context. The lectures and tutorial work will provide an opportunity to learn engineering properties of traffic streams along with relevant measurement and network analysis techniques.
The second strand of the course will be run from week 5 to week 12. This strand is subdivided into two components. Aim of the first component is to give students a brief overview of the geometric design of Rural Highways and Roads. Road design is usually undertaken by specialists under the supervision of a civil engineer. The engineer must therefore have a good understanding of the design methods and the quality requirements to enable him/her to evaluate the design. To enable students to gain practical experience in road design, a major assignment is set in week 5.
Students are expected to work in groups on this assignment during tutorials. The progress of the project work will be noted by the tutors. Some extra time will be required to complete the project assignment. Students must present and defend their assignment in week 11 and 12. The design strategies being taught are based on the Austroads Road Design Guide. The second component deals with pavement design and evaluation issues. Aim of this component is to present the knowledge necessary for the design of economical pavement thickness and composition, which will provide a satisfactory level of service for the anticipated traffic on that road.
We will address issues like pavement composition, pavement analysis, design traffic and loads, pavement materials, material stabilization, and pavement thickness design. The design methodology taught in the course is based on the Austroads Pavement Design Guide. In the tutorials students are supposed to solve task relevant for pavement material characterization and pavement design. Link to virtual handbook: http://www. handbook. unsw. edu. au/undergraduate/courses/2013/CVEN3401. html OBJECTIVES The first strand is expected to develop skills related to the analysis of traffic and transport systems.
Topics include: overview of the transport task, trends in motorization, sustainable transport, motorized and nonmotorized transport, traffic flow fundamentals, definitions and concepts related to land use and transport systems; prediction methods of future transport demand; modeling and evaluation of transport systems; transport operations and traffic management. ? ? ? ? Understand components of the field of transport engineering. Learn the basic terminology of transport and traffic engineering practice.
Learn urban transport planning concepts adopted by planning agencies and Roads and Traffic Authorities. Learn management methods related to road network systems. The second strand is expected to develop skills related to highway and pavement design. Topics include: introduction to road design, route location process, design practice of urban and rural roads, road traffic loadings, subgrade evaluation, base and sub-base materials, surfacing, design of flexible pavements. During the course we will: ? ? ? ? ? Introduce the basic principles of road geometric design.
Explain the methods of geometric design including horizontal and vertical alignment design and design of cross-sections as well as earthwork volume calculations. Gain skills in selection and thickness design of pavements. Study the fundamental characteristics of various pavement components and pavement materials. Understand the factors affecting the performance of pavements. TEACHING STRATEGIES The following teaching strategies will be used the course. Private Study ? ? Review lecture material and textbooks Do set problems and assignments 2 ? ? ?
Use Blackboard for discussions Download class notes from Blackboard if not collected during classes Reflect on class problems and assignments Lectures ? ? ? ? Find out what you must learn See methods that are not in the textbooks Follow worked examples Hear announcements on course changes Tutorials ? ? ? Be guided by tutors Practice solving set problems Ask questions Assessments ? ? Demonstrate your knowledge and skills Demonstrate higher understanding and problem solving abilities EXPECTED LEARNING OUTCOMES A successful study of the first strand will enable students to ?
? ? ? ? ? ? ? Explain relationships between fundamental traffic flow parameters; Describe basics of transport modeling concepts; Calculation methods related to each step of the four step planning process; Calculate trip generation; Calculations methods related to traffic assignment; Route choice calculations; Perform computational evaluations of network traffic management methods; Evaluate the transport system conditions based on demand forecast; By successfully completing the second strand of this course students will be able to ? ? ? ? ? ? ? ? ?
? Develop horizontal and vertical alignments for simple rural road sections on different types of terrain; Evaluate the alignment design according to various design criteria; Design cross-sections appropriate for various types of roads; Calculate the earthwork volumes of a designed road section; Present and document a road design in a standard format; Select type and composition of a pavement; Perform analyses of flexible pavements; Evaluate traffic load for pavement thickness design; Assess and specify pavement materials to meet performance requirements; Design thickness of flexible pavements.
For each hour of contact it is expected that a student will put in at least 1. 5 hours of private study. 3 ASSESSMENT The final grade for this course will be based on the sum of the scores from the assignments and the final examination. For the values of the single components see the table below: Strand 1 1 2 2 2 2 Component 1 1 1 1 2 2 Type of assessment Assignment Written exam Assignment/oral defense Written exam Assignment Written exam Value 1/6 1/6 1/3 none 1/6 1/6
The first component of the second strand is assessed entirely on the road design assignment. No question on this part of the course will appear in the final examination. The Final Examination is closed-book. Its duration is 2 hours. The formal exam scripts may not be retained by candidate. Students who perform poorly in the assignment and tutorials are recommended to discuss progress with the lecturer during the semester. The lecturer reserves the right to adjust the final scores by scaling if agreed to by the Head of School.
HURDLE REQUIREMENTS The pass mark in this course is 50% overall, however, students must score at least 40% in the final examination in order to qualify for a Pass in this course. Please note that passing of all course components is required to pass the subject.
