The idea of vehicle-highway communications sufficient to assume driving functions for the driver is not new. Researchers have articulated both its value and feasibility for several decades; and military and vehicle manufacturer test facility developments have proven the concept’s viability. As mounting congestion conflicts with environmental constraints, the Automated Highway System (AHS) promi...

Considerable experimental and theoretical research has been carried out in an attempt to design an automated highway system that can provide more efficient utilization of the highways and at the same time be safer and more comfortable than the current highway system. Here we present a unified framework for carrying out safety callculations for the automated highway problem. We obtain sufficient...

We present the design and veriication of inter-vehicle communication protocols for degraded modes of operation on Automated Highway System (AHS). We consider various hardware and sensor faults that can develop on the automated vehicle in an AHS and design discrete event supervisory controllers to stop the faulty vehicle or take it out of the highway in a safe manner. The protocols are veriied f...

In this paper we present a protocol that controls automated autonomous vehicles driving on a multiple merge junction highway. The protocol is distributed and it controls both merging and yielding. We show a simulation study that presents the protocol and its impacts on safety and congestion under diierent operating conditions. Our main result is that for simultaneous safe and eecient operations...

Highway automation has recently enjoyed renewed research interest as a method for solving highway congestion problems. To determine the feasibility of automated highways, it will be essential to estimate the automated highway benefits. A critical task in the analysis of automated highway benefits is to estimate the potential increase in highway capacity. This paper uses deterministic approximat...
