Scenario

A city’s administration isn’t driven by the goal of maximizing revenues or profits but instead looks at improving the quality of life of its residents. Many American

cities are confronted with high traffic and congestion. Finding parking spaces, whether in the street or a parking lot, can be time-consuming and contribute to

congestion. Some cities have rolled out data-driven parking space management in an effort to reduce congestion and make traffic more fluid.

You’re a data analyst working for a mid-size city that has anticipated significant increments in population and car traffic. The city is evaluating whether or not it

makes sense to invest in infrastructure to count and report the number of parking spaces available at the different parking lots downtown. This data would be

collected and processed in real-time, feeding an app motorists can access to find parking space availability in different parking lots throughout the city.

Part 1: Data Manipulation

Download the Parking Lot Use data set. The data set has the following columns:

• LotCode: a unique code that identifies the parking lot

• LotCapacity: a number with the respective parking lot capacity

• LotOccupancy: a number with the current number of cars in the parking lot

• TimeStamp: a day/time combination indicating the moment when occupancy was measured

• Day: the day of the week corresponding to the TimeStamp

Insert a new column, OccupancyRate, recording occupancy rate as a percentage with 1 decimal. For instance, if the current LotOccupancy is 61 and LotCapacity is

577, then the OccupancyRate would be reported as 10.6 (or 10.6%).

Using the OccupancyRate and Day columns, construct box plots for each day of the week. You can use Insert > Insert Statistic Chart >Box and Whisker for this

purpose. Is the median occupancy rate approximately the same throughout the week? If not, which days have lower median occupancy rates? Which days have

higher median occupancy rates? Is this what you expected?

Using the OccupancyRate and LotCode columns, construct box plots for each parking lot. You can use Insert > Insert Statistic Chart >Box and Whisker for this

purpose. Do all parking lots experience approximately equal occupancy rates? Are some parking lots more frequented than others? Is this what you expected?

Select any 2 parking lots. For each of them, prepare a scatter plot showing occupancy rate against TimeStamp for the week 11/20/2016 – 11/26/2016. Are

occupancy rates time dependent? If so, which times seem to experience the highest occupancy rates? Is this what you expected?

Part 2: Presentation

Prepare a 12- to 16-slide presentation with detailed speaker notes and audio, graphs, and tables.

Your audience is the city council, which is responsible for deciding whether the city invests resources to set in motion the smart parking space app.

Complete the following in your presentation:

• Outline the rationale and goals of the project

• Utilize box plots showing the occupancy rates for each day of the week. Include your interpretation of results.

• Utilize box plots showing the occupancy rates for each parking lot. Include your interpretation of results

• Provide scatter plots showing occupancy rate against the time of day of your selected 2 parking lots. Include your interpretation of results

• Make a recommendation about continuing with the implementation of this project.

Include speaker notes that convey the details you would give if you were presenting. You will record your speaker notes.

Ensure that the slides contain only essential information and as little text as possible.
