Collision warning system based on probability density functions

In this paper, a collision warning method between the host vehicle and target object(s) is studied. A probabilistic collision warning method is proposed, which is, in particular, useful for objects, e.g. vulnerable road users, which trajectories can rapidly change heading and/or velocity with respect to time. A vehicle is equipped with the probabilistic collision warning system and its functionality is validated in experiments with a bicyclist as target object

A270 Demo Schokgolfdemping

In februari 2010 zijn een aantal grootschalige experimenten uitgevoerd op de A270 tussen Helmond en Eindhoven. Het doel van deze experimenten is om de potentie van coöperatieve systemen te demonstreren voor het dempen van schokgolven en daarmee de mobiliteit op de Nederlandse snelwegen te kunnen vergroten. De experimenten vinden plaats op een bestaande snelweg om te demonstreren dat dit soort systemen overal ingezet kunnen worden. Een cooperatief systeem is ontwikkeld dat een individueel advies geeft aan de bestuurder in welke mate hij moet versnellen of vertragen. Deze testlocatie is uitgevoerd met 20 videocamera’s om de verschillen te meten tussen de groep voertuigen met coöperatief systeem en een referentie groep. De resultaten van deze experimenten worden hier gepresenteerd en besproken

Results of cooperative driving applications of the SPITS project

In this paper, the design and results of two cooperative driving applications are presented that both increase traffic flow on highways by reducing shockwave traffic jams and decrease the risk of head-on collisions. The first application is an advisory system based on vehicle-vehicle communication that showed positive results with a penetration level of 100% of equipped vehicles. The second application is both an advisory and automated system based on infrastructure-vehicle communication that showed positive results with a penetration level of 10%-30%

Advisory and autonomous coopeerative driving systems

In this paper, the traffic efficiency of an advisory cooperative driving system, Advisory Acceleration Control is examined and compared to the efficiency of an autonomous cooperative driving system, Cooperative Adaptive Cruise Control. The algorithms and implementation thereof are explained. The results of both systems are presented and discussed

Formation Control of Unicycle Mobile Robots: a Virtual Structure Approach

In this paper, the formation control problem for unicycle mobile robots is studied. A virtual structure control strategy with mutual coupling between the robots is proposed. The rationale behind the introduction of the coupling terms is the fact that these introduce additional robustness with respect to perturbations as compared to typical leader-follower approaches. The applicability of the proposed approach is shown in experiments with a group of mobile robots controlled over a wireless communication network

The experimental setup of a large field operational test for cooperative driving vehicles at the A270

In this paper, a large field operational test (FOT) for cooperative driving systems, which take place on a public highway, is discussed. The experimental setup consist of a specific driver support system, which is closely related to cooperative adaptive cruise control (CACC) systems. Instead of autonomous vehicles, drivers are precisely advised how to accelerate or decelerate their vehicle. The location, A270 between Helmond and Eindhoven, is equipped with over 20 video cameras in order to monitor the performance of the equipped vehicles versus the non-equipped vehicles. The first results of this large-scale FOT are presented and discussed. ©2010 IEEE
