A Realistic Simulator for the Design and Evaluation of Intelligent Vehicles
The number of vehicles hitting the road each day is rapidly increasing, and several problems, such as traffic conges- tion or driver safety, can no longer be solved in the same fashion as before. Intelligent transportation systems could potentially solve part of these problems, but prototyping, designing and testing cooperative smart vehicles is a cumbersome task. This paper presents a realistic simulator, capable of operating both at microscopic and sub-microscopic level, where intelligent vehicles can be designed and analyzed with a pragmatic approach. A number of advances in robotics have already been transferred to vehicular technology, with a potential increase of this trend into the future. Here, we develop a plugin for a well-established robotics simulator (Webots), in order to reinforce at the virtual level this cross-fertilization between the two areas and create a baseline for realistic studies of future solutions in real intelligent vehicles
DEMO: Simulation of Realistic Mobility Model and Implementation of 802.11p (DSRC) for Vehicular Networks (VANET)
An ad hoc network of vehicles (VANET) consists of vehicles that exchange
information via radio in order to improve road safety, traffic management and
do better distribution of traffic load in time and space. Along with this it
allows Internet access for passengers and users of vehicles. A significant
characteristic while studying VANETs is the requirement of having a mobility
model that gives aspects of real vehicular traffic. These scenarios play an
important role in performance of VANETs. In our paper we have demonstration and
description of generating realistic mobility model using various tools such as
eWorld, OpenStreetMap, SUMO and TraNS. Generated mobility scenario is added to
NS-2.34 (Network Simulator) for analysis of DSR and AODV routing protocol under
802.11p (DSRC/WAVE) and 802.11a. Results after analysis shows 802.11p is more
suitable than 802.11a for VANET.Comment: 4 pages, 6 figures, International Journal of Computer Applicatio
Formative Evaluation of Engineering Designs Using Driver Performance in a Immersive Driving Simulator
The systems engineering approach employs iterative evaluation of human factors issues throughout the system design process. Formative evaluation and refinement of user interfaces promotes cost savings by continuously validating design concepts and defining needs for improving the designs at the earliest possible point in the engineering process. Testing may use varying levels of prototypes of the system or simulations of its responses and user interfaces. While human factors evaluation frequently uses paper or foam board mockups, immersive driving simulators enhance the process by incorporating realistic road geometries and traffic flows and by requiring driver perception, decision making, and control actions in realistic scenarios and timelines. Three studies conducted in the Western Transportation Institute driving simulation laboratory are summarized. These used an immersive driving simulator to evaluate drivers’ responses to (1) Intelligent Transportation System (ITS) deployments on a rural highway, (2) the user interface to a lane departure warning system, and (3) a proprietary cooperative warning system for installation on the exterior of vehicles
Assessment of traffic impact on future cooperative driving systems: challenges and considerations
Connect & Drive is a start-up project to develop a cooperative driving system and improve the traffic performance on Dutch highways. It consists of two interactive subsystems: cooperative adaptive cruise control (CACC) and connected cruise control (CCC). To assess the traffic performance, a traffic simulation model will be established for large-scale evaluation and providing feedbacks to system designs. This paper studies the factors determining the traffic performance and discusses challenges and difficulties to establish such a traffic simulation model
The Leeds Advanced Driving Simulator: Three Years In Operation
The Leeds Advanced Driving Simulator (LADS) at the University of Leeds is a medium cost fixed-base simulator and its development has been funded by the Science and Engineering Research Council (now EPSRC). It has been fully operational since mid-1993 for rural-road scenes (Carsten and Gallimore, 1993) but currently simulation of urban environments and vehicle interactions are possible too. This paper focuses on the recent development of LADS. Also detailed other recent research projects carried out in the simulator to date
