  • Self rule organization in a non-signal urban traffic flow

    Publication Year: 1997, Page(s):643 - 648
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (488 KB)

    Deals with analysis of the dynamic behavior and collective rule organization in a motor vehicle traffic model on a non-signal street. In the non-global information and operating model, we analyze how individual agents affect the “rule” which exists as a common knowledge in the city, and investigate a process of rule organization. Experimental results imply that the rule organization pr... View full abstract»

    Efficient channel allocation for the purpose of vehicle-to-vehicle communications in automated highway system (AHS) is an unsolved problem. The extension of cellular mobile framework to the AHS is inefficient and faulty. We propose two algorithms in this paper: 1) a centralized algorithm that allocates channels by keeping track of the vehicles through a network of detectors; and 2) a mixed-control...

  • A new control strategy for a signalized traffic intersection

    Publication Year: 1997, Page(s):284 - 289
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (396 KB)

    A traffic control problem can be formulated as a decision-making problem for a stochastic dynamic system. Optimal traffic signal settings at intersections can minimize the vehicle delay time or the queue length at a stop line. In this paper, a new adaptive control strategy for signalized intersections is developed and tested by simulation. The simulation results show significant improvement over t... View full abstract»

  • Estimation of preceding vehicle's driving state

    Publication Year: 1997, Page(s):242 - 247
    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»

    Some key objectives of the ITS community are to improve the efficiency of the nation's highways using proven technologies; allow for future expansion and growth; and allow for incorporation of emerging technologies. This paper describes the design of an Advanced Traffic Management System (ATMS) for Interstate 476 (I-476) that fulfills these objectives. The ATMS on I-476 blends conventional sensor ...

    The data acquisition system (DAS) installed in the ACC-equipped vehicles is designed to collect, process, and store both numerical and video data files using two on-board computers to quantify aspects of the driving process that are pertinent to the control of speed and clearance gap relative to the closest preceding vehicle. The data are collected and stored on a trip-per-trip basis. Once a trip ... View full abstract»

  • An advanced vehicle control method using independent four-wheel-steering system

    Publication Year: 1997, Page(s):954 - 959
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (404 KB)

    This paper describes an advanced vehicle control method using independent four wheel steering system and roll stiffness control for advanced vehicle control system (AVCS) handling and stability. At accelerating and at braking on a cornering of a vehicle, each tire force coefficient of the vehicle is very different because of load transfer and nonlinearity of tire forces. Therefore, four-wheel-stee... View full abstract»

    We present a system for extracting lane marker information from image data in a form suitable for use in the automated steering of moving vehicles. The algorithm was designed with speed and simplicity in mind. It assumes a flat, dark roadway with light colored lane markers, either solid or dashed, painted on it. The algorithm is based on extracting statistically significant `bright' regions from t... 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»

    An axle-counting equipment using a laser-scanning range finder has been proposed and developed for the first time in order to improve the accuracy of vehicle classification in nonstop electronic toll collection systems. Because of laser-scanning at the high frequency the high-speed response of 6 msec for the axle-detection allowed a vehicle traveling at speed over 60 km/h. Although the wheel is bl...
