Advanced Vehicle Control Systems (AVCS) as envisioned by the California Partners for Advanced Transit and Highways (PATH) program. System simulation is crucial to ensure that every portion of the whole system we have designed will perform adequately together. For automated highway systems, simulation is essential for controller design. To create a more realistic simulation environment, we need ...

This paper investigates the age and sex distribution of at-fault drivers with respect to fatal crashes on the interstate and state highways in Florida. The study finds that the younger and older drivers of both sexes are more likely to cause fatal crashes compared to the „average‟ middle-aged drivers. The female oldest (>=75 years) drivers are at highest level of vulnerability of causing fatal ...

Communication of information from the roadway infrastructure to vehicles is expected to enhance Automated Highway Systems (AHS) by supporting subsystem functions like vehicle motion control, multiple vehicle coordination, and vehicle navigation. A suitable communication channel is information coding in the lateral reference used for automatic steering and lane keeping control, e.g. in the magne...

Supercomputing networks are designed to minimize message latency. The focus on low latency implies a best effort attempt to deliver each message injected onto the network as soon as possible. Ostensibly, prioritizing message latency is important, and there are numerous examples of applications that benefit from it, but while this latency-centric view of a network seems logical, it often leads t...

BACKGROUND Economic development is often evoked as a driving force that has the capacity to improve the social and health conditions of remote areas. However, development projects produce uneven impacts on local communities, according to their different positions within society. This study examines the spatial distribution of three major health threats in the Brazilian Amazon region that may un...

Ad hoc networks are self-configuring networks of mobile nodes, connected by wireless links. If a destination node is beyond the transmission range of an origin node, then the nodes must cooperate to provide a multi-hop route. Any node can act as a sender, receiver or transit node. It is clear that it is in a node’s interest to be a sender or receiver, but it is less clear what the value is of f...

plants polluted with pb produced by automobiles along the roads and highways have extensively been reported all over the world. it is the most important source of pollution in the environment. this research was carried out to determine the polluting degree of plants along the highways such as: rasht-anzaly, kelachay-ramsar, tehran-karaj, and isfahan-tehran. at each arbitrary point, a transect 1...
