NYC Citi Bike Heatmap

This project processes and visualizes 2024 NYC Citi Bike trip data. It includes data preprocessing with Python, data aggregation using C++ with OpenMP, and final visualization as an interactive heatmap.

Project Structure

• scripts/preprocess.py: Preprocesses raw Citi Bike data
• cpp/aggregation.cpp: Aggregates trip data in sequential/parallel using OpenMP
• scripts/visualize.py: Generates a heatmap from aggregated data
• nyc_citibike_heatmap.html: Output HTML file for visualization

Requirements

• Python 3
• C++ compiler with OpenMP support (e.g., g++-14)
• macOS (for open command, or modify accordingly for other OS)

Run the project

Run all commands together:

make all

Setup

Create a Python virtual environment and install dependencies:

make setup

Preprocess Data

Run the Python script to preprocess raw data:

make preprocess

Build Aggregation Binary

Compile the C++ aggregation program:

make build

Run Aggregation

Execute the compiled C++ program:

make run

Visualize Heatmap

Generate the heatmap using the processed data:

make visualize

Open Heatmap

Render the heatmap in your default browser (macOS):

make open
