Intelligent Transport Systems

Intelligent Transport Systems (ITS) refer to the application of advanced technologies—such as information, communication, computing, and sensor systems—to transportation networks to enhance their safety, efficiency, and sustainability. ITS integrates humans, vehicles, and infrastructure through real-time data collection and communication, leading to smarter management of traffic, improved mobility, and reduced environmental impact.
ITS forms a key component of modern smart city infrastructure, enabling seamless, connected, and adaptive transport solutions for urban and inter-urban mobility.

Definition and Concept

According to the World Road Association (PIARC), Intelligent Transport Systems are “advanced applications which, without embodying intelligence as such, aim to provide innovative services relating to different modes of transport and traffic management, and enable various users to be better informed and make safer, more coordinated, and ‘smarter’ use of transport networks.”
In simpler terms, ITS leverages digital and communication technologies to collect, analyse, and use information to optimise transportation operations.
Key technologies used include:

• Sensors and detectors (for vehicle counting, speed, and environmental monitoring)
• Global Positioning System (GPS)
• Geographical Information Systems (GIS)
• Wireless and mobile communication networks (3G, 4G, 5G)
• Artificial Intelligence (AI) and Machine Learning (ML)
• Internet of Things (IoT)
• Big Data analytics and cloud computing

Objectives of Intelligent Transport Systems

1. Enhance Road Safety: Reduce accidents by improving traffic control and driver awareness.
2. Optimise Traffic Flow: Minimise congestion through real-time monitoring and adaptive control.
3. Reduce Environmental Impact: Lower fuel consumption and emissions through smoother traffic management.
4. Improve Transport Efficiency: Enable quicker, more reliable, and cost-effective travel.
5. Support Multimodal Integration: Facilitate seamless movement between various modes—road, rail, air, and water.
6. Assist Law Enforcement: Improve compliance monitoring through automated systems like speed cameras and e-challan mechanisms.
7. Enhance User Experience: Provide accurate, real-time travel information for better decision-making.
