    The major functions, inputs, and outputs of the seven computer models developed during the Automated Guideway Transit (AGT) System Operations Studies (SOS) project are described. The models were designed to provide tools to enable the transportation community to analyze the operation of AGT systems in the complete spectrum of deployments. Three analytic models are described: the feeder system mode... View full abstract»

    A detailed description of a hierarchical system management concept that can operate a large automated guideway transportation system while maintaining achievable communication, vehicle control, and network management requirements is presented. The concept employs "smart" vehicle controllers which require minimal instructions from the network controller and can operate autonomously in case of a fai... View full abstract»

  • A headway safety policy for automated highway operations

    Publication Year: 1979, Page(s):22 - 28

    The maximum capacity, cost, and safety of an automated highway system are largely dependent on the selected headway policy, i.e., the specification of a minimum acceptable headway (as a function of speed) for mainline operations. Here a policy, designed to avert collisions due to "reasonable" lead-car decelerations, is presented and evaluated in the context of achieving high capacity (≥3600 ... View full abstract»

  • A rail-transit people-mover headway comparison

    Publication Year: 1979, Page(s):28 - 35
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (768 KB)

    For many years, General Railway Signal Company has supplied control systems for conventional rail transit. Headways for these systems range from minutes or hours down to as low as 75 s. In the last few years, the company has supplied control systems for people-mover applications in which minimum headways of 10-20 s have been achieved. There are many factors working together to permit achievement o... View full abstract»

  • Model-follower longitudinal control for automated guideway transit vehicles

    Publication Year: 1979, Page(s):36 - 45
    Cited by:  Papers (4)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (784 KB)

    An approach for the design of longitudinal control systems for automated transit vehicles using the vehicle-follower control concept is presented. It is shown that the spacing policy selected for system operations generates a dynamic model for ideal vehicle response during station keeping. The longitudinal control system should force the actual vehicle response to be as close to this model respons... View full abstract»

  • Implementation trade-offs for a short-headway vehicle-follower automated transit system

    Publication Year: 1979, Page(s):46 - 55
    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (792 KB)

    An important aspect in the design of automated guideway transit (AGT) systems is the communication requirements for the longitudinal control of vehicles, that is, the requirements to measure vehicle states, transmit this information between vehicles, and subsequently control the individual vehicles. This paper examines the trade-offs in the data rates, word lengths, and allowable transmission time... View full abstract»

    A "safe-approach" control policy is presented, which simultaneously handles close-headway vehicle following and various maneuver situations. The policy is illustrated with an example controller design and simulation evaluation. View full abstract»

  • Short station ramps for AGT systems

    Publication Year: 1979, Page(s):63 - 70
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (768 KB)

    Automated guideway transit (AGT) systems often have off-line stations, so that cars can travel directly from an origin to a destination, bypassing the intervening stations. Trip time is reduced, and a more flexible overall management policy is possible. The disadvantage of off-line stations is that additional guideway is required for the station and its associated ramps. More guideway is expensive... View full abstract»

  • A state-constrained vehicle-follower approach to the station-egress problem

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (752 KB)

    Vehicle following represents one approach to the longitudinal control of vehicles in an automated guideway transit (AGT) system. Requirements for the use of such control for the merging of a vehicle from an off-line station into a mainline vehicle stream are discussed. Recently, a technique has been developed that incorporates state-variable constraints into the control law of a vehicle-follower c... View full abstract»

    The programmable digital vehicle control system or PDVCS is based upon the Intel 8080A microprocessor and is designed to replace the hardwired discrete components traditionally used in the on-board control of automated rapid transit vehicles. Although designed specifically for the advanced group rapid transit (AGRT) system under development by the Boeing Company, with funding by the Department of ... View full abstract»

  • Dynamic performance of automated guideway transit vehicles with dual-axle steering

    The lateral dynamic performance of automatically guided dual and single steered axle vehicles is determined using a three-degree-of-freedom nonlinear model. Vehicle acceleration levels and tracking errors are determined for performance during curve entry, station entry, and on straight but randomly irregular guideway references. Independent dual-axle controllers, yaw dual-axle controllers, and zer... View full abstract»

    Techniques for providing steering control for an automated vehicle using discrete reference markers fixed to the road surface are investigated analytically. Either optical or magnetic approaches can be used for the sensor, which generates a measurement of the lateral offset of the vehicle path at each marker to form the basic data for steering control. Possible mechanizations of sensor and control... View full abstract»

    Passenger acceptance of mass transit systems depends on predictable travel times. The major sources of travel time uncertainty are passenger wait delays due to system loading and travel time delays due to failures. The second of these effects is treated analytically. Travel time distributions are developed for a typical automated group rapid transit network with a passenger load of 14000 passenger... View full abstract»
