                              Civil Engineering                                 6th Semester
1.         RATIONALE
 Traffic engineering is a branch of civil engineering that uses engineering techniques to
 achieve the safe and efficient movement of people and goods on roadways. Knowledge
 and understanding of the basic concept of traffic Engineering is highly essential for the
 engineers designing and executing the road laying projects in order to make road. Traffic
 engineering plays a pivotal role in all facets of transportation, and given the ever-expanding
 population and infrastructure developments. This includes the planning and implementation
 of traffic control elements such as traffic sings, signals, and road markings to enhance safety
 for both drivers and pedestrians. The course aims to cultivate expertise in conducting diverse
 traffic surveys, deciphering and making sense of the collected data, and proposing solutions
 in the form of traffic control devices. At diploma level, students are expected to perform
 various traffic surveys, analyse traffic data and interpret the results appropriately in order
 to apply their knowledge in designing good road transport systems.
2.         COMPETENCY
 The purpose of this course is to help the student to attain the following industry identified
 competency through various teaching learning experiences:
   •     Execute the working and control of traffic engineering elements.
   •     Determine traffic requirements for road design after conducting the traffic surveys.
3.         COURSE OUTCOMES (COs)
 The practical exercises, the underpinning knowledge and the relevant soft skills associated
 with this competency are to be developed in the student to display the following COs:
       a) Analyze the road traffic characteristics.
       b) Undertake various types of road traffic studies.
       c) Use the relevant road traffic control devices.
       d) Interpret traffic management system.

      e) Suggest preventive measures to avoid accidents by analyzing the traffic conditions at
         site and maintain the road environment.
      f) Aware about advanced technology in traffic engineering.

 The following sample Affective Domain Outcomes (ADOs) are embedded in many of the above
 mentioned Cos and PrOs. More could be added to fulfil the development of this competency.
      a) Work as a leader/a team member.
      b) Follow safe practice on site.
      c) Follow ethical practices.
      d) Practice environmental friendly methods and processes. (Environment related)
 The ADOs are best developed through the laboratory/field based exercises. Moreover, the level
 of achievement of the ADOs according to Krathwohl’s ‘Affective Domain Taxonomy’ should
 gradually increase as planned below:
      i. ‘Valuing Level’ in 1st year ii. ‘Organization Level’
      in 2nd year.
      iii. ‘Characterization Level’ in 3rd year.
8.          UNDERPINNING THEORY
 Only the major Underpinning Theory is formulated as higher level UOs of Revised Bloom’s
 taxonomy in order development of the COs and competency is not missed out by the students
 and teachers. If required, more such higher level UOs could be included by the course teacher
 to focus on attainment of COs and competency.

10.          SUGGESTED STUDENT ACTIVITIES
Other than the classroom and laboratory learning, following are the suggested studentrelated
co-curricular activities which can be undertaken to accelerate the attainment of the various
outcomes in this course: Students should conduct following activities in group and prepare
reports of about 5 pages for each activity, also collect/record physical evidences for their
(student’s) portfolio which will be useful for their placement interviews:
        a) Prepare journals based on practical performed in laboratory.
        b) Group discussion on traffic jams and related probable solutions in the city.
        c)   Undertake micro-projects.
11.          SUGGESTED SPECIAL INSTRUCTIONAL STRATEGIES (if any)
These are sample strategies, which the teacher can use to accelerate the attainment of the
various outcomes in this course:
        a)   Massive open online courses (MOOCs) may be used to teach various topics/sub topics.
        b) Guide student(s) in undertaking micro-projects.
        c)   ‘L’ in section No. 4means different types of teaching methods that are to be employed
             by teachers to develop the outcomes.
        d) About 20% of the topics/sub-topics which are relatively simpler or descriptive in
           nature is to be given to the students for self-learning, but to be assessed using
           different assessment methods.
        e)   With respect to section No.11, teachers need to ensure to create opportunities and
             provisions for co-curricular activities.
        f)   Guide students on how to address issues on environ and sustainability.

12.           SUGGESTED MICRO-PROJECTS
 Only one micro-project is planned to be undertaken by a student that needs to be assigned to
 him/her in the beginning of the semester. In the first four semesters, the micro-projects are
 group-based. However, in the fifth and sixth semesters, it should be preferably be individually
 undertaken to build up the skill and confidence in every student to become problem solver so
 that s/he contributes to the projects of the industry. In special situations where groups have
 to be formed for micro-projects, the number of students in the group should not exceed three.
         The micro-project could be industry application based, internet-based,
workshopbased, laboratory-based or field-based. Each micro-project should encompass two or
more COs which are in fact, an integration of PrOs, UOs and ADOs. Each student will have to
maintain dated work diary consisting of individual contribution in the project work and give a
seminar presentation of it before submission. The total duration of the micro-project should
not be less than 16 (sixteen) student engagement hours during the course. The student ought
to submit micro-project by the end of the semester to develop the industry oriented COs. A
suggestive list of micro-projects is given here. This has to match the competency and the COs.
Similar micro-projects could be added by the concerned course teacher:
         a)       Prepare a model of traffic controlling devices.
         b)       Make posters showing traffic safety and awareness.
         c)       Prepare the charts showing different types of road signs.
         d)       Measure the spot speed on corridor of road way to analyze the percentile speed
                  graphically.
         e)       Prepare a report of a field visit to any major road intersection in your locality to
                  identify the type, working of traffic signals along with your recommendations.
         f)       Prepare a report of a field visit to any urban road way to identify the road signs
                  and corresponding markings on road.
         g)       Prepare a report on advanced road marking machinery and materials.
         h)       Perform traffic survey of busy road junction of city in groups and to suggest
                  measures for improvement.
         i)       Prepare a report of a field visit to any urban road to identify the traffic island along
                  with its sketch.
         j)       Undertake the process of planting, protecting and maintaining the trees along the
                  road.
         k)       Identify the existing street lighting system of any two types of roads.
         l)       Locate the points of conflicts in the diagram of a busy intersection on a major urban
                  road in your locality.
         m)       Identify the existing type of trees to suggest any relevant maintenance required.
