Abstract: With the rapid development of intelligent transportation systems, Python is a versatile, easy to learn and use The programming language is widely used in the development and application of intelligent transportation systems. This article demonstrates the advantages and application potential of Python in the field of intelligent transportation by analyzing application cases of Python in intelligent transportation systems and giving relevant code examples.

1. Introduction
   Intelligent transportation system refers to the use of modern communication, information, sensing and other technical means to realize traffic management and transportation through information perception, data processing, decision-making analysis and other processes of the transportation system. Intelligent systems for service and traffic control. With the continuous development of artificial intelligence, big data, and Internet of Things technologies, intelligent transportation systems are playing an increasingly important role in urban traffic management and traffic safety.
2. Advantages of Python in Intelligent Transportation Systems
   As a high-level, object-oriented, interpreted programming language, Python has the following advantages in the development and application of intelligent transportation systems:
3. 1 Versatility: Python has a wealth of third-party libraries and modules that can support data processing, machine learning, image recognition and other functions, and is suitable for various processing and analysis tasks in intelligent transportation systems.
   2.2 Easy to learn and use: Python’s syntax is concise and clear, easy to learn and use, lowering the entry barrier and allowing developers to focus more on the implementation of algorithms and business logic.
4. 3 Cross-platform: Python can run on multiple operating systems such as Windows, Linux, and Mac, making it easier for developers to develop and debug in different environments.
5. 4 Community support: Python has a huge open source community, and developers can share and obtain a large amount of code and resources to improve development efficiency.
   Based on the above advantages, Python is widely used in the development and application of intelligent transportation systems.
6. Application cases of Python in intelligent transportation systems
   3.1 Traffic data processing and analysis
   Traffic data processing and analysis is one of the core links of the intelligent transportation system. By collecting, cleaning, processing and analyzing traffic data, traffic conditions can be monitored and predicted in real time, providing a scientific basis for traffic management and decision-making.

Sample code:

import pandas as pd

# 读取交通数据
data = pd.read_csv('traffic_data.csv')

# 数据清洗
cleaned_data = data.dropna()

# 数据分析
avg_speed = cleaned_data['speed'].mean()
max_speed = cleaned_data['speed'].max()
min_speed = cleaned_data['speed'].min()

print("平均车速：", avg_speed)
print("最大车速：", max_speed)
print("最小车速：", min_speed)

3.2 Image recognition and intelligent monitoring
Image recognition and intelligent monitoring technology play a vital role in intelligent transportation systems. By using the image processing library and machine learning algorithm in Python, the recognition and analysis of traffic images can be realized, and intelligent traffic monitoring and vehicle tracking can be achieved.

Sample code:

import cv2

# 加载交通监控视频
cap = cv2.VideoCapture('traffic_video.mp4')

while True:
    ret, frame = cap.read()
    if not ret:
        break
    
    # 图像处理和车辆识别
    processed_frame = process_frame(frame)
    vehicles = detect_vehicles(processed_frame)
    
    # 显示识别结果
    for vehicle in vehicles:
        cv2.rectangle(frame, vehicle['bbox'], (0, 255, 0), 2)
    
    cv2.imshow('Traffic Monitor', frame)
    if cv2.waitKey(1) == ord('q'):
        break

cap.release()
cv2.destroyAllWindows()

4. Conclusion
   As a versatile, easy-to-learn and use programming language, Python provides powerful tools for the development and application of intelligent transportation systems. support. This article demonstrates the advantages and application potential of Python in the field of intelligent transportation by analyzing application cases of Python in intelligent transportation systems and giving relevant code examples. In the future, with the continuous development of intelligent transportation technology, Python will be more and more widely used in the field of intelligent transportation.
