In the development of advanced driver-assist systems (ADAS) for lane-keeping, one important design objective is to appropriately share the steering control with the driver. Hence, the steering behavior of the driver must be well known beforehand. This paper adopts the well-known two-point visual driver model to characterize the steering behavior of the driver, and conducts a series of field tests...
Very popular system in VANET applications is collision prevention system that helps to prevent from chain collisions. The system obtain the vehicle information and traffic information during any emergency situation happens. It broadcast the warning messages to other vehicles for automatic break control to prevent collisions. The system sends the emergency message to vehicles in the network, before...
In this keynote, we look the fundamental limits of the information propagation speed in large scale mobile and intermittently connected networks, where end-to-end multihop paths may not exist and communication routes may only be available through time and mobility. We first introduce some analytical tools to derive generic theoretical bounds for the information propagation speed in this networks....
Socio-technical systems are systems where autonomous humans and computational entities collectively collaborate with each other to satisfy their goals in a dynamic environment. To be resilient, such systems need to adapt to unexpected human behaviours and exogenous changes in the environment. In this paper, we describe a framework for the development of social-technical systems where adaptation is...
Automotive industry is about to make a cutting-edge step in terms of vehicular technologies by letting vehicles communicate with each other and create an Internet of Things composed by vehicles, i.e., an Internet of Vehicles (IoV). In this context, information dissemination is very useful in order to support safe critical tasks and to ensure reliability of the vehicular system. However, the industrial...
In the era of the Internet-of-Vehicles (IoV), all components in an Intelligent Transportation System (ITS) can be connected to improve the traffic safety and transportation efficiency. In order to maximize the utilization of the resources, e.g., computation, communication and storage resources, the cloud computing technique could be integrated into vehicular networks. Meanwhile, a cloud-assisted vehicular...
Platooning is an emergent vehicular application aiming at increasing road safety, efficiency and driving comfort. The cooperation between the vehicles in a platoon is achieved by the frequent exchange of periodic broadcast Cooperative Awareness Messages (CAMs) also known as beacons. CAM triggering conditions are drafted in the standard ETSI EN 302 637-2 and are based on the dynamics of an originating...
Recently, involving wireless communication technologies in deployment of new vehicular networks becomes more attracting to the research community and vehicle manufacturers. It is beneficial in providing intelligent transportation system as well as new assistant services to drivers. However, the limitation of resources in mobile vehicles is a significant technical challenge in the deployment of new...
Vehicular ad hoc networks are expected to suffer from channel congestion, due to the high number of vehicles moving on the roads, the limited available bandwidth and the many applications that they will support. In order to mitigate such problem, ETSI has recently specified the Decentralized Congestion Control (DCC) mechanisms for Intelligent Transportation Systems (ITS) operating in the 5 GHz range...
I-CROSS is an intelligent system designed to help drivers to decide the time slot in which an intersection can be crossed without collisions. This service has been developed as a desktop application that can be executed in Android devices. The set of algorithms that determine the crossing order are fed with information about surrounding vehicles: actual and further GPS position, speed and an identification...
In this paper we propose and evaluate a heterogeneous architecture for location service in vehicular environments. The proposed Location Service utilizes the infrastructure of cellular networks to offload the Dedicated Short Range Communication (DSRC) systems from the signalling overhead required for the location service. We evaluate the performance of such a hybrid solution in terms of overhead and...
Vehicular delay-tolerant networks (VDTNs) are a promising technology for vehicular communications, creating application scenarios that enable non-real time services with diverse performance requirements. Because of scarce network resources (e.g. bandwidth and storage capacity) and node's short contact durations, the underlying VDTN network infrastructure must be capable of prioritizing traffic. This...
