CENE 470/CM 470 Team Project
The main program used in this project is called GIS(ArcMap), please search for it so you understand what this program is for. Please follow the instructions to start writing the report as they’re provided at the end of the uploaded file.
The outcomes of the project vary depending on the majors (ME, CENE/CM).
The final team project requires up to three 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 -0.20
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 (to be announced). 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. (three hyperlinked points on each
south and north bound)
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 don’t 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.
