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...

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...

We study the wireless communication among highway vehicles in the newly-assigned 5.9 GHz Dedicated Short Range Communication (DSRC) spectrum. A vehicle-vehicle Location-Based Broadcast (LBB) communication protocol is designed to meet highway safety applications’ communication requirements. The analytical expressions of the performance of the protocol in terms of probability of transmission fail...

A stochastic automaton can perform a finite number of actions in a random environment. When a specific action is performed, the environment responds by producing an environment output that is stochastically related to the action. This response may be favourable or unfavourable. The aim is to design an automaton that can determine the best action guided by past actions and responses. Using Stoch...

Driver assistance and automation technologies simulate the driver’s sensorimotor system to operate a vehicle either temporarily during emergencies or for prolonged periods. Such new information and control technologies that make vehicles smarter ...

A b s t r a c t In this paper, longitudinal and lateral vehicle control for Automated Highway Systems (AHS) are studied together for their coupling effects. It is shown that longitudinal controllers which directly control the wheel slip are inherently more stable, especially during lateral maneuvers on very slippery road conditions, than longitudinal controllers which do not take wheel slip int...

A vehicular ad hoc network (VANET) is a relatively new term for an old technology – a network that does not rely on pre-existing infrastructure. When integrated into the intelligent transportation systems (ITS), it can provide direct vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications, thereby can greatly improve the safety and efficiency of road traffic. The emerging an...

human driver or control the vehicle autonomously, they usually must make these decisions in real time with only incomplete information. So, human drivers still must maintain control over the vehicle. Advanced in-vehicle information systems (IVISs) endow vehicles with different types and levels of intelligence to complement the driver.2 Their introduction has allowed an almost symbiotic relation...
