Optimizing Traffic Data Analysis with Pandas and Python: A Step-by-Step Guide
The code provided is for data analysis and visualization using Python and pandas libraries. Here’s a summary of what each part does:
- Data Loading: The code starts by loading the dataset from a CSV file into a pandas DataFrame.
- Data Preprocessing: The code applies various preprocessing techniques, such as:
- Rounding time intervals to 15-minute resolutions using
round_timefunction. - Adding new columns for concise time interval formatting using
add_consice_interval_columnsfunction.
- Rounding time intervals to 15-minute resolutions using
- Grouping and Aggregation: The code groups the data by both time interval and day of the week, and then aggregates the results using
group_by_concised_intervalfunction. - Data Visualization: The code prints the resulting DataFrame for each group.
The output shows the average speed and volume of traffic in different time intervals (15-minute resolutions) for each day of the week.
Example Output:
| Group | time_interval_concise | average_speed | volume |
|---|---|---|---|
| Hostname_place_duo | Friday 08:30 | 59 | 1 |
| Hostname_place_uno | Friday 08:15 | 65 | 1 |
This output indicates that on Fridays, at 8:15 AM and 8:30 AM, the average speed of traffic in the place_uno location was 65 mph and 59 mph, respectively. Similarly, for the place_duo location.
Overall, this code demonstrates how to analyze and visualize traffic data using pandas and Python, with a focus on time interval and day of the week grouping.
