1 RMIT Classification: Trusted CIVE1180 – Transport Engineering 1 Assessment Task 3 – Workplace Practical Assessment Time to submit: 24 h Open-Book policy; max plagiarism = 5% IMPORTANT: this is an individual assessment Background Two roads intersect in a rural area of regional Victoria, and this intersection is unsignalised. According to Austroads, both of these roads fall under the same category and were originally designed to accommodate local traffic only. They each feature one lane per direction along with shoulders. However, due to the recent surge in new dwellings and commercial developments in the area, there is an urgent need to widen one of these two roads to a design with two lanes per direction, plus shoulders. Road A has an operating speed of (59 + x) km/h, while Road B operates at (45 + 0.5x) km/h. To determine the value of ‘x,’ refer to the third digit of your student number (e.g., if your student number is 345678, ‘x’ equals 5). It’s important to note that the two roads intersect at a 90-degree angle. As part of the design, you must incorporate an auxiliary lane to facilitate left turns. This lane should enable vehicles traveling on the major road (the road with the highest approach speed) to make left turns onto the minor road. The intersection can be situated in any area of the terrain file provided. Keep in mind that you should choose the intersection location judiciously. As each student will work independently during the assessment, and given the size of the terrain, ensure that your location selection is unique. Penalties will be applied for duplications. As a road engineer, your role is to design the intersection in strict adherence to Austroads guidelines, as covered in this course. The client’s preference is to receive your design in the form of a technical report. While there is no specific minimum or maximum length for each section of the report, you should be mindful of the available time for completion. This aspect will test your time management skills. The technical report should at least include the following parts: 1. General Introduction: Begin by providing a concise overview of the project. Elaborate on the reasons necessitating the construction of a larger intersection. 2. Understanding the Terrain and Document Collection: Briefly describe the overall topography of the terrain. Explain the rationale behind your choice of the specific
2 RMIT Classification: Trusted project location (i.e., the area where you intend to position the intersection). Additionally, provide a list of documents that you think would be required from the Client to complete the design of the intersection in real life. 3. AutoCAD Part 1: – Select an area in the terrain file spanning at least 300 x 300 m. Create a plan view of the ‘old’ intersection (prior to the road widening). Add necessary details and annotations to ensure clear visualization for contractors on the construction site. Produce a PDF print-out of the 300 x 300 m area, selecting an appropriate sheet size. Indicate the scale factor used on the PDF print-out. – Widen the road drawn in the previous step by adding one lane per direction to the major approach road. No auxiliary lane is required at this stage. Again, print out the 300 x 300 m area in PDF format with the scale factor clearly noted. You may include additional annotations if needed. 4. Calculations Part 1: – Design the auxiliary lanes for left turns from the major approach road to the minor approach road. This entails calculating the deceleration length, taper length, parallel lane, divergence length, and curve radius for the left turn. Provide a detailed procedure in the report, including any relevant equations and data/tables. – Note: Assume any missing data with clear justification in the report. Provide reference of Austroads documents/tables/etc if used. 5. AutoCAD Part 2: – Utilizing the most recent drawing of the widened intersection and based on your previous calculations, create a plan view of the final intersection with the auxiliary lanes. Print out the 300 x 300 m area in PDF format, specifying the scale factor used. Include additional annotations on the drawing as necessary. – Generate a cross-section at a location of your choosing that encompasses at least the auxiliary lanes and its left curve. Print this section in PDF format using an appropriate scale factor. Include all necessary annotations for a clear visualisation of the auxiliary lane and the left curve. 6. Calculations Part 2: – Employ the finalised layout of the intersection to calculate the approach sight distance for each approach. Take into account that the longitudinal grade must be extracted from the terrain file, and this value may vary depending on the intersection’s location on the map. – Similarly, compute the safe intersection sight distance for each approach and determine the crossing sight distance on the major road for pedestrians wishing to cross it.
3 RMIT Classification: Trusted 7. Draft a Short Conclusion Section: Summarise the key findings and decisions made throughout the project. — Well done! You have just designed your first intersection! There is no specific format required for preparing the final report. However, it is essential to bear in mind that this workplace practical assessment is designed to simulate the format and structure of a technical report. Each student is expected to create a distinct intersection project. Plagiarism or copying from other students will lead to a deduction of grades but might have more serious consequences too. IMPORTANT: 1) There will be no responses to emails sent to the tutors and course coordinator during the assessment. All the necessary information is already provided in the text. 2) In cases where you believe that certain data is missing, it is acceptable to make assumptions. However, you must justify the reasoning behind your assumptions within the report. 3) Please note that screenshots for the AutoCAD drawings are not permitted. Uploading a screenshot instead of a PDF-printed file will result in grade deductions. 4) Late submissions will incur a penalty of 10% for each day of delay.
