This paper addresses the problem of coordinated path-following of networked autonomous vehicles with discrete-time periodic communications. The objective is to steer a group of autonomous vehicles along given spatial paths, while holding a desired inter-vehicle formation pattern. For a class of vehicles, we show how Lyapunov based techniques, graph theory, and results from networked control sys...

Modern cars feature many embedded systems that monitor and manage all the critical sensors and actuators. The interconnection of such systems is a challenging task since the information to be exchanged is of mission-critical nature and affects the driving experience. The vehicle connectivity can be further extended with Vehicle-to-Vehicle (V2V) technology, which allows cars to exchange sensory ...

Intelligent transport system (ITS) has large potentials on road safety applications as well as nonsafety applications. One of the big challenges for ITS is on the reliable and cost-effective vehicle communications due to the large quantity of vehicles, high mobility, and bursty traffic from the safety and non-safety applications. In this paper, we investigate the use of dedicated shortrange com...

The paper introduces the potentiality of wireless communications in road safety improvement. New systems based on Vehicle/infrastructure and vehicle/vehicle cooperation are enabled. The results of a recent project “SAFE TUNNEL” and new projects like “SAFESPOT”, “GOODROUTE”,”WATCHOVER”, are described. All these research projects are co-funded by European Commission (EC) and witness the strong co...

Abstract Vehicular Ad hoc Networks (VANETs) have an important role in improving road safety especially when no infrastructure is available. Inter vehicle communications (IVCs) provide decentralized communications where vehicles cooperate together to disseminate road traffic data relying on broadcasting reports and warning messages. Trusting the data of every warning message must be accomplishe...

Emerging Vehicular Ad-hoc NETworks (VANETs) are representing the preferred network design for Intelligent Transportation Systems (ITS), mainly based on Dedicated Short-Range Communications (DSRC) for Vehicle-to-Vehicle (V2V) communications (Held, 2007). Future vehicles will be fully networked, equipped with on-board computers with multiple Network Interface Cards (NICs) (e.g., Wi-Fi, HSDPA, GPS...
