As we venture down this path, it's crucial to demystify AI, understand its real-world applications, and critically examine both its immense potential and the challenges it presents.
What AI currently is and isn’t capable of
At its core, artificial intelligence refers to computer systems capable of performing tasks that typically require human intelligence. These include visual perception, speech recognition, decision-making, and language translation. However, it's important to dispel some common misconceptions:
- AI is not a magic pill that can instantly solve all problems. It's a tool that requires careful implementation and human oversight.
- Current AI systems are "narrow" AI, designed for specific tasks. We're still far from "general" AI that can match human-level intelligence across all domains.
- AI doesn't (yet) "think" like humans. It uses complex algorithms and vast amounts of data to recognise patterns and make predictions.
In transportation, AI manifests in various forms, from machine learning algorithms that optimise traffic flow to computer vision systems that govern micromobility fleets or enhance vehicle safety. By understanding these fundamental concepts, we can better appreciate AI's role in shaping the future of mobility.
Key applications of AI in transportation
Traffic management and urban mobility
AI is revolutionising how cities manage traffic and urban mobility. Intelligent traffic systems use real-time data from sensors, cameras and connected vehicles to dynamically adjust traffic signals, reducing congestion and improving traffic flow. AI algorithms can predict traffic patterns, allowing city planners to proactively manage transportation networks and respond to changing conditions.
For example, some cities are implementing AI-powered traffic management systems or using AI-enabled crowd sourced dashcam video feeds that can optimise routes and reduce average travel times by up to 25% and cut emissions by adapting to real-time traffic conditions. These systems can also prioritise public transit and emergency vehicles, further enhancing urban mobility.

AI is making public transportation more efficient, reliable, and user-friendly. Machine learning algorithms can analyse historical and real-time data to optimise bus and train schedules, predict maintenance needs, and improve route planning. AI-powered chatbots and mobile apps are enhancing the passenger experience by providing personalised trip planning and real-time updates.
In some cities, AI systems are being used to dynamically adjust bus routes based on demand, reducing wait times and improving service in underserved areas. Computer vision systems are also put to use on buses to detect and enforce vehicular violations of dedicated bus lanes which helps ensure timely bus service. This not only increases ridership but also contributes to more equitable and accessible public transportation.
Autonomous vehicles and micromobility
Perhaps the most visible application of AI in transportation is in the development of autonomous vehicles (AVs). Self-driving cars, trucks, and buses use a combination of sensors, cameras and AI algorithms to navigate roads safely. While fully-autonomous vehicles are still in development, AI is already enhancing vehicle safety through advanced driver assistance systems (ADAS).
In the micromobility sector, AI is optimising the deployment and management of shared bikes, scooters, and other small vehicles. AI algorithms can predict demand patterns, ensuring vehicles are available where and when they're needed most. Computer vision technology is being used to enhance safety, for example, by detecting when riders are not wearing helmets or detecting what type of infrastructure (sidewalk, bike lane or street) is being used and sharing that data with urban planners.

Tolling and congestion charging
AI is streamlining tolling and congestion charging systems, making them more efficient and fair. Machine learning algorithms can analyse traffic patterns to implement dynamic pricing, encouraging off-peak travel and reducing congestion. AI-powered image recognition systems can accurately identify vehicles and process payments without the need for physical toll booths, reducing traffic bottlenecks. Similarly, some of the most hotly-contested real estate in cities is the kerb; AI-powered computer vision systems are being deployed to proactively manage and enforce proper use of it by various stakeholders depending on the time of day or week.
Beyond that, these systems can be integrated with broader urban mobility strategies, using AI to optimise pricing and incentives to achieve specific policy goals, such as reducing emissions or promoting public transit use.
Logistics and supply chain
In the world of freight and logistics, AI is driving significant improvements in efficiency and sustainability. AI-powered route optimisation algorithms can reduce fuel consumption and delivery times. Predictive maintenance systems use machine learning to anticipate equipment failures, reducing downtime and extending the lifespan of vehicles.
AI is also enhancing warehouse operations through automated inventory management and robotic picking systems. In ports and intermodal facilities, AI is being used to optimise container stacking and vessel loading, significantly reducing turnaround times.
Benefits and opportunities
Increased efficiency and productivity
AI's ability to process vast amounts of data and make rapid decisions is driving unprecedented efficiency gains across the transportation sector. From optimizing traffic flow to streamlining logistics operations, AI is helping to reduce delays, cut costs and improve resource utilisation. For instance, AI-powered predictive maintenance can reduce vehicle downtime by up to 20%, while route optimisation algorithms can cut fuel consumption by 15% or more.
Enhanced safety
Safety is critical in transportation, and AI is emerging as a powerful tool in reducing accidents and saving lives. Advanced driver assistance systems (ADAS) and autonomous vehicle technologies use AI to detect and respond to potential hazards faster than human drivers. In public transit and freight operations, AI can monitor driver behaviour and alertness, preventing accidents caused by fatigue or distraction. The potential impact is significant – some estimates suggest that widespread adoption of AI-driven safety technologies could reduce traffic fatalities by up to 90% in the long term.
Environmental sustainability
As the world grapples with the urgent need to address climate change, AI offers promising solutions for reducing the environmental impact of transportation. By optimising routes, reducing congestion and improving vehicle efficiency, AI can significantly cut fuel consumption and emissions. In public transit, AI-driven systems can encourage ridership by improving service reliability and convenience, potentially reducing private car usage. Moreover, AI is playing a crucial role in the integration of electric vehicles and renewable energy systems, helping to balance grid loads and maximise the use of clean energy in transportation.
