    Publication Year: 1997, Page(s):566 - 571
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (520 KB)

    Communications between vehicles and the roadside is a key component for many ITS applications. Cellular digital packet data (CDPD) is one possible method to provide this communications link. We investigate the effect of mobile velocity on the performance of a CDPD-type wireless modem in the multipath fading environment. To incorporate the effect of vehicular velocity, we employ a Markovian model t... View full abstract»

    Several intelligent vehicle applications require knowledge of the presence of objects in the path of the host vehicle. Current approaches to this in-path decision process do not fully utilize the information available from the forward-looking sensor. This paper describes a path algorithm in which the observed trajectories of preceding vehicles are used to determine the shape of the road in front o... View full abstract»

    This paper presents the current status of the National Automated Highway System Consortium (NAHSC) regarding automated highway systems supporting mixed (automated and manual) traffic. One motivation for mixed traffic is to build up as technology matures. But human factors must also be considered, since the driver will not monitor reliably. Response to all hazards encountered by human drivers is es... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (328 KB)

    Estimation methods of the driving state (position, velocity, acceleration) and the lane displacement of forward vehicles are proposed. The lane displacement denotes the lateral displacement from the host vehicle's running lane. The driving state of each vehicle is estimated using Kalman filter; and it is corrected in the case that the estimation error becomes large, which means the acceleration ch... View full abstract»
