AI-Assisted IoT Solutions for Optimized Public Transportation

1. Introduction

The intersection of Artificial Intelligence (AI) and the Internet of Things (IoT) represents a transformative force in various sectors, notably in public transportation. As urban populations swell and mobility challenges intensify, the need for efficient transit solutions has never been more pressing. Leveraging AI-assisted IoT technologies can significantly enhance the performance and reliability of public transportation systems. These advancements facilitate real-time data collection and analysis, enabling transport authorities to optimize routes, reduce waiting times, and improve overall service quality. Moreover, integrating AI algorithms allows for predictive maintenance of transit vehicles and infrastructure, thereby preventing service disruptions and increasing passenger satisfaction. By harnessing these innovations, urban planners can create smarter, more responsive transportation networks that meet current demands and anticipate future growth and shifts in mobility patterns, ultimately contributing to more sustainable urban living environments.

2. Enhancing Operational Efficiency

Integrating AI-assisted IoT solutions within public transportation systems offers a transformative approach to enhancing operational efficiency. By deploying advanced communication networks, such as 3D wireless technologies, agencies can ensure timely communication and real-time situational awareness during critical incidents. This is particularly vital when managing large facility evacuations or addressing emergencies like wildfires, where swift coordination and resource allocation are essential [2]. Furthermore, advancements in IoT concepts—such as the Internet of Robotic Things (IoRT)—facilitate seamless interactions between autonomous vehicles and infrastructure, improving responsiveness and service delivery. The synergy between IoT and AI in public transport can lead to optimized routes, reduced operational costs, and increased rider satisfaction, simplifying complex logistical challenges while enabling dynamic adaptability to fluctuating demands [3]. Municipalities can create a more resilient, efficient, and responsive public transportation ecosystem by leveraging these technologies.

3. Improving User Experience

Integrating AI-assisted IoT solutions into public transportation systems significantly enhances user experience by delivering real-time data and personalized services. Such solutions help streamline operations, offering passengers timely information on transit schedules and alternative routes to reduce wait times and improve overall accessibility [6]. Furthermore, using computer vision and sensor networks in traffic management ensures efficient traffic flow, ultimately minimizing congestion and enhancing safety, as discussed in the context of Intelligent Transportation Systems [4]. Alongside these advancements, the interplay between smart home technologies and public transport can also foster an environment of convenience for users, allowing seamless connectivity between various modes of transport within smart urban ecosystems [5]. By addressing infrastructure and interoperability challenges, cities can create cohesive networks that prioritize user needs and adaptively evolve to meet them, leading to a more user-centric public transportation landscape [7].

3.1 Smart Ticketing Systems and Personalized Travel Information

The evolution of public transportation systems is increasingly intertwined with the adopt Smart ticketing systems and personalized travel information are vital components in enhancing user experience and operational efficiency. By leveraging AI, these systems can analyze individual travel behaviors and preferences, providing tailored recommendations that streamline the commuting experience. In this context, smart mobility encompasses efficient route planning and real-time updates and facilitates inclusive mobility by catering to diverse user needs, thus promoting sustainable urban development [8]. Furthermore, as outlined in the Transport 2040 report, integrating advanced technologies into transportation infrastructures is crucial for facilitating the smooth operation of automated and semi-automated vehicles, ultimately transforming the nature of city travel [9]. This dual focus on personalization and technology supports a holistic approach to public transportation, encouraging higher usage rates and fostering more environmentally friendly commuting patterns.

Dpred = α + β × H + β × W + β × T,

Where:

Dpred: predicted demand at a given stop.

H: hour of the day.

W: day of the week (e.g., 1 for Monday to 7 for Sunday).

T: temperature or another environmental factor (e.g., weather condition index).

α: intercept of the regression model.

β1, β2, β3: regression coefficients estimated from historical data.

II. Route optimization using travel time and distance.

To optimize the route, the goal is to minimize the total travel time, taking into account distance and expected traffic:

Di Ttotal = ∑ , Si,opt

Ttotal: total estimated travel time for the route.

Di: distance of segment i.
