Their ability to access hard-to-reach locations makes UAVs helpful in emergencies to searc...Show More
Accurate demand forecasting is crucial for reducing food waste, enhancing resilience, and promoting sustainability in food systems. Relying only on historical sales data is inadequate to predict the demand for perishable food products. The remaining shelf-life of food products and their qualities need to be considered as they play a vital role in the forecasting process, leading to accurate and re...Show More
Over the years, the Vehicle Routing Problem (VRP) has been extensively studied. As real-world scenarios and technol-ogy evolve, researchers are increasingly integrating drones with trucks, leading to the development of the Two-Echelon Vehicle Routing Problem (2EVRP). The 2EVRP involves dividing the route plan into two segments: the first echelon operated by trucks and the second by drones. With th...Show More

The increased reliance on Unmanned Aerial Vehicles (UAVs) in various industries exalts the security requirements since it is critical to protect these systems from any cyber-attack. GPS spoofing presents an important challenge by deceiving UAVs through false GPS signals that would disrupt their operations, thereby endangering them. As a countermeasure, this study introduces a method of detecting G...Show More
Dynamic ridesharing has gained significant attention in recent years. However, existing ridesharing studies often focus on optimizing order dispatching and vehicle repositioning separately, leading to short-sighted decisions and underutilization of the ridesharing potential. In this paper, we propose a novel joint optimization framework called JODR. By coordinating order dispatching and vehicle re...Show More
Unmanned Aerial Vehicles (UAVs) have immense potential to enhance Intelligent Transport Systems (ITS) by aiding in real-time traffic monitoring, emergency response, and infrastructure inspection, leading to rich data collection, lower response times, and efficient urban mobility management. Machine learning (ML) is a crucial component in UAV-assisted ITS as it processes UAV-captured data in both t...Show More
In the public transportation system, punctuality benefits both bus operation and passengers’ travel experience. However, uncertainty exists due to complex traffic conditions and heterogeneous driving behaviors. To analyze bus operational uncertainty, transport planners and bus operators need a tool that supports multi-granular modeling, spatio-temporal representation, and interactive exploration. ...Show More
Interactions and conflicts between vulnerable road users, mainly pedestrians and cyclists, are frequently observed on crosswalks, especially in urban areas with relatively high traffic volume. To alleviate the potential safety risks, one possible measure is to adopt the segregated crosswalk to provide separate crossing space for pedestrians and cyclists. However, the crossing behaviours of pedestr...Show More
Both urban rail transit (URT) and regular bus transit (RBT) systems are essential components of a multi-modal transport system in metropolises. The efficient and effective cooperation between URT and RBT systems plays an important role in enhancing the reliability and resilience of a URT system to quickly respond to disruptions. In this study, a resilience enhancement model for the URT network is ...Show More
As an emerging innovative public transit service, the app-based demand-responsive feeder transit (DRFT) incorporated with a mobility-as-a-service (MaaS) platform provides on-demand, customized and flexible travel service. It serves as a good alternative for providing the first- and last-mile transport service. The study addresses the routing design optimization problem of the DRFT in the era of Ma...Show More
The outbreak of COVID-19 has made a profound impact on mobility, especially for public transport users. Extensive research has been conducted on the change of travel patterns in major cities where public transport systems have been well developed and heavily used. However, in small cities, the public transport network is relatively sparse, especially in suburban areas, which makes the correspondin...Show More
With an increasing number of electric vehicles but relatively insufficient charging facilities, how to utilise and manage the existing charging resource in an efficient and effective way becomes an important challenge to address. In this paper, a charging resource allocation model is proposed to balance the uneven charging demand at different charging stations and minimise the total average waitin...Show More
Traffic conflicts between bus passengers and cyclists surrounding bus stops are frequently observed, which may reduce their travel comfort and cause potential safety issues. However, such conflicts and safety risk at different types of bus stops have rarely been investigated. To fill the research gap, this study aims to investigate the conflicting behaviours between bus passengers and cyclists and...Show More
With the development of charging technology, chargers with dropped price and increased charging power make fast charging more applicable and competitive to provide efficient and effective charging solution to electric vehicles. Compared to normal chargers, fast chargers can top up battery in a short time, which enables battery electric buses to get top-up charging at selected bus stops when the bu...Show More
Operational disturbances within 30 min, namely, short-term operational disturbances (STODs), occur frequently during the daily operation of an urban rail transit (URT) system. Therefore, there is an urgent need to assess a network’s ability to respond to STODs to improve its operational level. The resilience of a URT network jointly considering turn-back operations, the occurrence time of STODs, a...Show More
An optimal train schedule enables the railway system to serve maximal passengers with limited resources. However, inappropriate train services may cause a diversity of adverse impacts such as service delay and long waiting times. This study aims to improve train service with a new schedule compared to the existing train schedule. To develop an alternative train service with a schedule solution, a ...Show More
Different from the existing train delay studies that had strived to explore sophisticated algorithms, this paper focuses on finding the bound of improvements on predicting multi-scenario train delays with different machine learning methods. Motivated by the observation of deep learning methods failing to improve the prediction performance if the delay occurs rarely, we present a novel augmented ma...Show More
As a common phenomenon, overtaking behaviour is frequently observed on pedestrian flow, which not only reshapes pedestrian flow but also generates adverse impacts on pedestrian safety to some extent. Prior research focused on unidirectional pedestrian modelling, especially with overtaking behaviour, is limited. Moreover, pedestrian behaviour in the context of COVID-19 is rarely investigated. Inspi...Show More
Proper vehicle scheduling and charging scheduling play an essential role in an efficient, effective and economical (3E) operation of electric bus fleet. An optimal vehicle scheduling can minimise the number of required electric buses and deadhead trips. Compared to normal plug-in charging at depot, fast charging at stops can reduce the required battery capacity, the number of deadhead trips, and f...Show More
Bus bunching, a phenomenon due to the failure of headway or timetable adherence, often causes low level of public transit service with poor bus on-time performance and excessive passenger waiting time. To mitigate bus bunching, an accurate and real-time prediction method plays an important role. In this paper, we propose a supply-demand seq2seq model called SD-seq2seq to predict bus bunching using...Show More
Bus bunching is a result of sophisticated traffic condition, unstable bus operation and dynamic travel demand, which not only causes passengers' dissatisfaction, but also degrades the bus service performance. To tackle the bus bunching issue, multiple steps are usually adopted, from bus bunching identification to solution development. This paper serves as the first-mile work of a series of studies...Show More
