Analytical Models for Vehicle/Gap Distribution on Automated Highway Systems

Analytical Models for Vehicle/Gap Distribution on Automated Highway Systems

Automated Highway Systems (AHS)

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...

Fault-Tolerant Control for Automated Highway Systems

Increasing highway traffic congestion and real estate costs that limit the building of new highways has brought about a renewed interest in an Automated Highway System (AHS) where the vehicle steering task (“lateral control”) and the braking/throttle tasks (“longitudinal control”) are taken over by computers to increase the throughput of existing highways. Since safety plays a key role in the d...

Optimal routing for automated highway systems

We present a routing guidance approach that can be used in Automated Highway Systems (AHS). We consider automated highway systems in which intelligent vehicles organised in platoons drive to their destination, controlled by a hierarchical control framework. In this framework there are roadside controllers that provide speed and lane allocation instructions to the platoons. These roadside contro...

Consortium on Automated Analytical Laboratory Systems (CAALS)

USA Industry and government both depend heavily on analytical laboratory measurements. Although these measurements provide critical feedback in many situations , such as product quality assurance, acceptance testing, and regulatory compliance, they are generally viewed with mixed feelings. On the positive side, industry recognizes that improvements in product and process capability often depend...
