We present a routing guidance approach that can be used in Intelligent Vehicle Highway Systems (IVHS). We consider IVHS consisting of automated highway systems on which intelligent vehicles organized 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 p...

Many animals learn to follow habitual routes between important locations, but how they encode their routes is still largely unknown. Desert ants traveling between their nest and a food site develop stable, visually guided routes that can wind through desert scrub without the use of trail pheromones. Their route memories are sufficiently robust that if a nest-bound ant is caught at the end of it...

The laboratory toxicologist is frequently faced with the challenge of selecting appropriate vehicles or developing utilitarian formulations for use in in vivo nonclinical safety assessment studies. Although there are many vehicles available that may meet physical and chemical requirements for chemical or pharmaceutical formulation, there are wide differences in species and route of administrati...

Most of public travel information services nowadays are limited to the driving navigation or bus/subway guidance. Practical needs for pedestrian navigation yet haven’t got met enough and usually result in unacceptable travel route planning. This paper presents an approach on building Walkway network with different map layers for pedestrian specified facilities, and then implements pedestrian ai...

When a natural disaster occurred, some roads cannot be used anymore and sometimes blocked. Also, survivors and refugees cannot follow the evacuation procedures by just using default maps after disaster. A previous study proposed a safety route guidance system that can be used after natural disasters by using participatory sensing. The system estimates safe routes and generates an evacuation map...

Many problems in transportation can be formulated as fixed point problems, or equivalently as a systems of nonlinear equations, as for example multi-user equilibrium problems, planning problems, and consistent anticipatory route guidance generation. These fixed point problems are often characterized by the fact that there is no analytical form of the objective function, the computational cost o...

The sizes of the BGP routing tables have increased by an order of magnitude over the last six years. This dramatic growth of the routing table can decrease the packet forwarding speed and demand more router memory space. In this paper, we explore the extent that various factors contribute to the routing table size and characterize the growth of each contribution. We begin with measurement study...

specifying the position of their nests and feeding sites and for guiding their path along fixed routes between them (Santschi, 1913; Tinbergen, 1932; Baerends, 1941; Rosengren, 1971; Collett et al., 1992; Wehner et al., 1996). When guided by visual landmarks, insects demonstrate an impressive ability to use long-term visual memories for controlling their movements. Current evidence suggests tha...
