Python Code Example: Traffic Data Analysis for Smart City Management

Setup and Libraries

First, let’s set up our environment and import necessary libraries:

import pandas as pd
import matplotlib.pyplot as plt
from sklearn.cluster import KMeans
from sklearn.preprocessing import StandardScaler

Data Preparation

Assume we have traffic data in a CSV file named traffic_data.csv with columns like 'location', 'time', 'vehicle_count', etc.:

# Load the dataset
traffic_data = pd.read_csv('traffic_data.csv')

# Quick view of the data
print(traffic_data.head())

Data Processing

Next, we process the data to make it suitable for analysis:

# Converting time to a more usable format
traffic_data['time'] = pd.to_datetime(traffic_data['time'])

# Grouping data by hour and location to get average vehicle count
traffic_grouped = traffic_data.groupby([traffic_data['time'].dt.hour, 'location']).mean().reset_index()

Data Analysis

Now, let’s analyze this data to identify traffic patterns:

# Applying K-Means clustering to identify high-traffic areas
scaler = StandardScaler()
scaled_data = scaler.fit_transform(traffic_grouped[['vehicle_count']])

kmeans = KMeans(n_clusters=3)  # Assuming 3 clusters for simplicity
traffic_grouped['cluster'] = kmeans.fit_predict(scaled_data)
# Displaying the cluster centers
print(kmeans.cluster_centers_)

Visualization

Finally, visualize the results for better understanding:

# Plotting the traffic clusters
plt.figure(figsize=(10, 6))
for cluster in range(3):
    clustered_data = traffic_grouped[traffic_grouped['cluster'] == cluster]
    plt.scatter(clustered_data['time'], clustered_data['vehicle_count'], label=f'Cluster {cluster}')
plt.title('Traffic Patterns in Smart City')
plt.xlabel('Hour of Day')
plt.ylabel('Average Vehicle Count')
plt.legend()
plt.show()

Explanation of the Code

1. Data Loading: The code begins by loading a hypothetical traffic dataset using Pandas.
2. Data Processing: It processes the data to extract meaningful features like the average vehicle count per hour for each location.
3. Clustering with K-Means: The K-Means algorithm is applied to identify patterns in traffic density, categorizing them into different clusters.
4. Visualization: Finally, the clustered data is visualized using Matplotlib to illustrate high and low traffic periods throughout the day.
