CENE 470/CM 470 Team Project

The outcomes of the project vary depending on the majors (ME, CENE/CM).

The final team project requires four students from the same major (ME or CENE/CM) working as a team. The topic of the final project will be the applications of GIS in engineering or construction.

The purpose of the project is to help Arizona Department of Transportation (ADOT) engineers in assessing pavement conditions of the truck Lane along I-17 between Exit 333 to Exit 337 including North and South bounds (Fig 1a and Fig. 1b). To detect the roughness of freeway conditions, we will use an mobile app (i-OS) called myVibreometer (Fig. 2) downloaded and installed in a smartphone to be attach it on the dash board of a vehicle (Fig. 3). Your team will drive a vehicle traveling on the truck lane of I-17 along both south and north bounds between Exit 337 to Exit 333.of I-17to collect vibration data.

When completion of data collection, you will need to import all .csv files to ArcGIS to analyze and digitize vibration data using knowledge you have learned from HW 1 through HW8 and provide two major Points of Interest/Damage (moderate and severe points on I-17) on maps.

The formation of GIS mapping are shown below:

Coordinate system: GCS Spheroid-basedInternational 1924

Three levels of pavement distress:

Slight: gravity of acceleration (g force) is less than 0.15 (g<0.15) or greater than -0.15 (g>-0.15)

Moderate: gravity of acceleration (g force) is between 0.15 and 0.20 or between -0.15 and -0.

Severe: gravity of acceleration (g force) is equal or greater than 0.2 (g>=0.2) or equal or less than -0.2 (g<=-0.2)

Note: the range to define the three pavement distresses varies depending on what type of vehicle and its speed (pickup, SUV, sedan, truck…). Your team member must work together to determine an appropriate range to display the moderate and severe points on your GIS maps.

Each student will be required to show their understanding of their project through an oral demo on May 31, 2018. The final project report will consist of:

A cover page (1 page) Introduction of final project (0.5-1 page) Methodology: How did you implement the project (0.5-1 page) GIS mapping and data analysis (1-2 pages): a. How did you determine those points based on your vibration data collected on I- 17?

b. Using maps to indicate where the points of interest (severe and moderate points) are located. c. Use Google Earth to locate your severe and moderate points and set up hyperlinks to those images in your maps. d. It is recommended that you take video on highway pavements while travelling on I-17 for data collection. This will help you detect and locate moderate and severe points properly is you dont use Google Earth. e. Provide a table showing how many points of severe and moderate are detected on north and south bounds. Discussions (1-2 pages): a. ME major: based on a motion equation (see below)discuss how an individual component (Mass, damping, and Stiffness) of a vibration system contributes to motion and vibration of a vehicle and how an individual component can influence the accuracy of the vibration analysis. A Motion equation can be expressed as:

[]{}+[]{}+[]{}={()}
where [],[] and [] represent the total mass matrix, the total damping matrix, and
the total stiffness matrix of a vehicle; {}, {}, {} are acceleration, speed, and
displacement vector of nodes in the three directions (x, y, and z) for a given vehicle
b. CENE/CM major: discuss how the vibration-based and smartphone-based
method can be used in engineering and construction project. For example, could
we use this method for QC and QA on construction? Why and How? Or could we
use this method in engineering surveying on highway pavements? Why and
How?...List your thoughts.

Recommendations and conclusions (0.5 page): what are your recommendations for engineers to maintain highway pavement conditions and what conclusions you get from the project 1 margin, 12 front size, single-spaced. All tables and figures are embedded in your report. A total of 8-10 pages The instructor will collect all your data including report for grading.

Demonstration schedule will be announced later the semester.
