This paper describes a multi-vehicle motion control framework for time-critical cooperative missions and evaluates its performance by considering two case studies: a simultaneous arrival mission scenario and a sequential auto-landing of a fleet of UAVs. In the adopted setup, the UAVs are assigned nominal spatial paths and speed profiles along those, and the vehicles are then tasked to execute c...

In modern vehicles, there are a lot of devices (GPS, Tachograph, GSM / GPRS. . . ) with different functions. These peripherals communicate with each other thanks to various media and protocols. The weakness of some protocols and standards obstructs the interoperability. They have to exchange useful information about the vehicle status and understand what is being shared. This paper aims to desi...

The desirable goal in passenger transportation is moving more people in fewer vehicles. This goal, in respect of road transport, can be attained by encouraging public transport modes like buses by assigning priority. This paper is concerned with the conceptual framework of a micro simulation model of highly heterogeneous traffic flow and application of the model to study the impact of exclusive...

This research addresses the problem of coordinating multiple autonomous underwater vehicle (AUV) operations. An intelligent mission executive has been created that uses multi-agent technology to control and coordinate multiple AUVs in communication deficient environments. By incorporating real time vehicle prediction, blackboard-based hierarchical mission plans, mission optimization and a distr...

In this paper, we study a rich vehicle routing problem incorporating various complexities found in real-life applications. The General Vehicle Routing Problem (GVRP) is a combined load acceptance and generalised vehicle routing problem. Among the real-life requirements are time window restrictions, a heterogeneous vehicle fleet with different travel times, travel costs and capacity, multi-dimen...

Autonomous flight of a single Unmanned Aerial Vehicle has become routine for many research teams. Our interests include multi-vehicle operation as well as developing guidance and control algorithms for each vehicle. These algorithms also need to be implemented in flight hardware and successfully flight tested. A flexible simulation environment is one of the key ingredients towards this goal, mo...

Transportation is one of the important infrastructures constituting the base and requisite for different levels of people’s access and movement to various locations. Transportation systems are one of the indices of the development of a region. Optimizing these systems contributes to improving performance and reducing costs of offering services to users. Hence, methods should be adopted with whi...

Future unmanned systems in the military will be highly heterogeneous in nature, with vehicles from multiple domains—aerial, underwater, and land—working in collaborative teams to complete a variety of missions. The complexity of supervising these teams will be enormous and will rely on human creativity, judgment, and experience. Therefore, the design and development of mission planning and moni...

Effective routing of vehicles remains a focal goal of all modern enterprises, thriving for excellence in project management with minimal investment and operational costs. This paper proposes a metaheuristic methodology for solving a practical variant of the well-known Vehicle Routing Problem, called Heterogeneous Fixed Fleet VRP (HFFVRP). Using a two-phase construction heuristic, called GEneral...

In this paper, we macroscopically describe the traffic dynamics in heterogeneous transportation urban networks by utilizing the Macroscopic Fundamental Diagram (MFD), a widely observed relation between network-wide space-mean flow and density of vehicles. A generic mathematical model for multi-reservoir networks with well-defined MFDs for each reservoir is presented first. Then, two modeling va...
