The physical Internet (PI) is a conceptual, innovative, and contemporary modular distribution logistics system that has garnered the interest of both researchers and practitioners as an alternative to conventional logistics. It aims to be more environmentally friendly, more socially responsible, and also more profitable. The key concept behind the PI logistics system is the routing of highly modular...
Emerging self-driving vehicles are vulnerable to different attacks due to the principle and the type of communication systems that are used in these vehicles. These vehicles are increasingly relying on external communication via vehicular ad hoc networks (VANETs). VANETs add new threats to self-driving vehicles that contribute to substantial challenges in autonomous systems. These communication systems...
In this paper we propose a security system to protect external communications for self-driving and semi self-driving cars. The proposed system can detect malicious vehicles in an urban mobility scenario. The anomaly detection system is based on fuzzy petri nets (FPN) to detect packet dropping attacks in vehicular ad hoc networks. The experimental results show the proposed FPN-IDS can successfully...
Vehicular ad hoc networks play an important role in the success of a new class of vehicles, i.e. self-driving and semi self-driving vehicles. These networks provide safety and comfort to passengers, drivers and vehicles themselves. These vehicles depend heavily on external communication to predicate the surrounding environment through the exchange of cooperative awareness messages (CAMs) and control...
The emergence of self-driving and semi self-driving vehicles which form vehicular ad hoc networks (VANETs) has attracted much interest in recent years. However, VANETs have some characteristics that make them more vulnerable to potential attacks when compared to other networks such as wired networks. The characteristics of VANETs are: an open medium, no traditional security infrastructure, high mobility...
Vehicular ad hoc networking (VANET) have become a significant technology in the current years because of the emerging generation of self-driving cars such as Google driverless cars. VANET have more vulnerabilities compared to other networks such as wired networks, because these networks are an autonomous collection of mobile vehicles and there is no fixed security infrastructure, no high dynamic topology...
This study investigates the use of tire slip-angle feedback in the development of an adaptive control method for vehicle stability. The estimates for tire slip-angle variations are provided through a sensor fusion approach that integrates measurements from an intelligent tire system with results from a sliding mode observer. The algorithm yields to a control law in terms of an auxiliary steering angle...
In this paper, demand response concept has been exploited to control the real time charging of plug-in hybrid electric vehicles. A developed voltage stability index is embedded in the continuous power-flow solution process adopted in distribution management systems (DMS). If the distribution system is unbalanced, positive sequence data is used for evaluating the voltage stability index (SI). The developed...
Active safety systems utilize information about the vehicle's state and possibly the surrounding environment to assist the driver if a traffic situation is considered hazardous. The decision to assist the driver is based on sensors that are more or less subjected to errors. In this paper, we study the influence of input perturbations on decision functions in active safety systems. We present a framework...

In this paper we present a fastest path algorithm that contains multiple unique destinations, which is a specialization of the Traveling Salesman Problem (TSP) with intermediate cities. This algorithm can be used with Intelligent Transportation System (ITS) applications for determining the fastest route to travel to a set of destinations, such as required by delivery companies. The dynamic behavior...
The Global Positioning System (GPS) provides special features which can be utilized for wide range of applications. By providing information such as location, direction and speed, GPS is traditionally used for navigation. Nowadays many more applications, from farming, surveying to incident detection in fact fully utilized the GPS. This study accesses GPS signal and determines vehicle location and...
In this paper the possibility to predict vehicle loss of control using information about the host vehicle's state and the road ahead is investigated. A threat assessment algorithm that predicts loss of control based on assumptions of the driver's future behavior is proposed. The algorithm can be used in an active safety system to motivate e.g. either earlier conventional yaw control interventions...
