TAKEN 5. Reinforcement Learning for Mobility Under Traffic Disruptions

Traffic networks can be significantly affected by unexpected events such as accidents, road closures or sudden congestion. Conventional route-planning approaches may struggle to adapt efficiently to these changes. This project investigates whether reinforcement learning can learn adaptive routing strategies that respond to unexpected disruptions. The learned approach will be evaluated in a simulated transport network … Read more

TAKEN 4. Robust Multi-Agent Reinforcement Learning for Cooperative Lane Changing

Vehicles approaching highway merges or lane-changing situations need to coordinate their actions to maintain safety and traffic efficiency. This project investigates whether multiple reinforcement learning agents can learn cooperative lane-changing strategies. Different training approaches will be compared with conventional rule-based strategies. The project will evaluate their impact on traffic safety, travel time and overall traffic … Read more

TAKEN 3. Reinforcement Learning for Sustainable Route Choice in Urban Mobility

Choosing the best route through a city is challenging because traffic conditions change continuously. Reinforcement learning (RL) provides a way for an agent to learn effective route-selection strategies by interacting with a simulated transport network. This project will investigate whether an RL-based approach can learn to select routes that reduce travel time and congestion compared … Read more

TAKEN 2 – Personalised Reinforcement Learning for Mobility Recommendations

Different travellers may have different preferences when choosing how and when to travel. While some may prioritise travel time, others may prefer cheaper, less crowded or more environmentally friendly options. This project investigates whether reinforcement learning can be used to learn personalised mobility recommendations based on individual preferences and feedback. The project will explore how … Read more

TAKEN 1 – Efficient Multi-agent Reinforcement Learning for Cooperative Route Planning

In cooperative multi-agent reinforcement learning, several agents have to learn how to work together. A challenge is that they can sometimes settle on a reasonably good way of cooperating, even though a much better joint solution exists. This project investigates whether  the way learning experiences are selected and used during training could influence which solution … Read more

TAKEN 7 – Cooperative CAV decision-making using Graph Neural Networks

Before fully autonomous driving is achieved, connected autonomous vehicles (CAVs) will operate for a certain period in mixed traffic, which includes both CAVs and human-driven vehicles (HDVs). The dynamic and interactive conditions in mixed traffic scenarios renders CAV decision making particularly challenging. This project will investigate the use of Graph Convolutional  Deep Reinforcement Learning for … Read more

Mitigating Bus Bunching using Reinforcement Learning – No longer available

An ideal bus route would offer highly predictable inter-bus arrival times to travellers, in particular, overcoming the well-known ‘bus bunching’ phenomenon – “I waited ages then three came together!”. There are many sources of variability in journey times such as traffic conditions, the impact of traffic lights, and interference between buses themselves, e.g.,  queueing at … Read more

Improving Urban Travel-time Reliability with Connected and Automated Vehicles and Reinforcement Learning – No longer available

Poor travel-time reliability (TTR) in our cities means that travel times for the same journey are both highly variable and unpredictable, and also gives rise to similar negative impacts on the environment and the economy as does traffic congestion. Being able to offer a high degree of TTR is therefore highly desirable for travellers and … Read more

Slot-based Motorway Driving for Connected and Automated Vehicles – No longer available

The Research Ireland funded ClearWay1 project is investigating new models of road management is which each vehicle is allocated a so-called ‘slot’ in which to travel for the duration of its journey. Adherence to travelling in its allocated slot ensures congestion-free travel from source to destination for each vehicle (in the absence of unexpected events). … Read more

ML-powered Parking Assistance System – No longer available

Parking in busy locations eg at large-scale events (such as concerts and mass-participation sporting events) or in shopping centres at busy times (eg during ‘Christmas shopping’) often results in traffic congestion in surrounding areas (see, for example, [1], for an extreme example!). This may arise due to vehicles searching for, entering, and leaving parking spaces … Read more
