Human Supervisory Control of Aircraft, Rail and Highway Vehicles Human Supervisory Control of Aircraft, Rail and Highway Vehicles

چکیده
This paper reviews recent trends in control of aircraft, rail and highway vehicles toward supervisory control. Supervisory control means the human operator intermittently specifies goals, constraints and procedural information to a computer, monitors synoptic displays of state information, and tasks the computer to execute the instructions automatically. This trend has been driven by new sensor, communication and computer technology. Full automation of these transport systems is currently unacceptable, not only for reasons of safety, but also because radical departure from present systems is technologically and economically infeasible, in addition to which the public does not like radical change. Commercial and military aircraft are easily the most advanced of the three transportation modes. Rail and highway systems are currently undergoing rapid transformation, nevertheless impeded by economic and other societal constraints. Examples of new technological developments are given for each mode. Common problems are then described. Finally, some methodological elements are mentioned which are essential to resolving these problems.

Developing Operator Capacity Estimates for Supervisory Control of Autonomous Vehicles
OBJECTIVE This study examined operators' capacity to successfully reallocate highly autonomous in-flight missiles to time-sensitive targets while performing secondary tasks of varying complexity. BACKGROUND Regardless of the level of autonomy for unmanned systems, humans will be necessarily involved in the mission planning, higher level operation, and contingency interventions, otherwise know...
متن کاملIdentifying at Highway-Rail Grade Crossing Hotspots in Canada
This research presents a risk-based Hotspots identification model at highway-rail grade crossings in Canada. Two sets of models were developed to predict collision frequency and consequence at individual crossings. A two–dimensional graphic approach was adopted to combine these two models together to predict the risk at each crossing. Hotspots based on collision history tended to be widespread ...
متن کاملVehicle Following Control Design for Automated Highway Systems
A, utomatic vehicle following is an important feature of a fully rpartially automated highway system (AHS). The on-board vehicle control system should be able to accept and process inputs from the driver, the infrastructure, and other vehicles, perform diagnostics. and provide the appropriate commands to actuators so that the resulting motion of the vehicle is safe and compatible with the AHS o...
متن کاملRailroad-Highway Grade Crossings A Look Forward
The Committee on Railroad-Highway Grade Crossings is concerned with the safety and other affected characteristics (including economic considerations, traffic flow and delay, and countermeasures) of both highway and rail traffic at points where they intersect at grade, including the proximate surrounding environment and rail transit facilities. This is a white paper on the state of the art and t...
متن کاملAn Intelligent Agent for Supervisory Control of Teams of Unihabited Combat Air Vehicles (ucavs)
Achieving air superiority is a key tenet of U.S. fighting doctrine. To meet this requirement, flight packages of Uninhabited Combat Air Vehicles (UCAVs) have recently been proposed for future conflicts. One operations concept calls for UCAVs to possess significant onboard intelligence that enables real-time decision-making without continuous human intervention. In this case, although the vehicl...
