NYC Open Data Visualization

This repository contains a Python script that visualizes New York City open data by combining three datasets:

• NYC Street Centerline (CSCL)
  Data source: NYC Street Centerline

• Automated Traffic Volume Counts (ATVC)
  Data source: Automated Traffic Volume Counts

• New York City Borough Boundaries (NYBB)
  Data provided by the geodatasets library

Overview

The atvc.py script performs the following steps:

1. Load Datasets

   • Reads the NYC Street Centerline dataset (GeoJSON format).
   • Loads the NYC Borough Boundaries and converts the CRS to EPSG:4326.
   • Reads the Automated Traffic Volume Counts (CSV format).

2. Data Preparation

   • Filters the ATVC dataset to include only the most recent year for each street.
   • Calculates the average traffic volume for each street.
   • Removes streets with zero traffic volume.

3. Visualization

   • Colors the streets based on the average traffic volume using a color mapping (from red to green).
   • Plots the CSCL and NYBB datasets.
   • Saves the resulting plot as a PDF (nyc_atvc.pdf).
