Automated and Cooperative Vehicle Merging at Highway On-Ramps

Vehicle merging control design for an automated highway system

The merging process in an Automated Highway System (AHS) is divided into a speed adjustment stage and a lane merging stage. Three important parameters, namely, acceptability, availability and pursuability, are analyzed to characterize the AHS lane gap features for the ideal, smooth and safe merging of the ramp vehicles. Three control guidance laws, namely, linear, optimal and parabolic speed pr...

Lane Changing Prediction Modeling on Highway Ramps: Approaches and Analysis

The lane-change maneuver prediction system for human drivers is valuable for advanced driver assistance systems (ADAS) in terms of avoiding unnecessary maneuver efforts or unsafe merging, as well as encouraging lane-change behaviors that could increase travel efficiency. Learning the decision-making process of an intended lane changing is essential to model semi/full autonomous vehicles control...

Emergency vehicle maneuvers and control laws for automated highway systems

The operation and transit of emergency vehicles on an automated highway system (AHS) designed under the control architecture proposed in the California Partners for Advanced Transit and Highways (PATH) program is described. The term emergency vehicles is used in a general sense to describe vehicles, such as police cars, ambulances, and tow trucks, that may service faults inside or outside the A...

Vehicle 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...
