Two-lane highways refer to roadways consisting of two lanes in the cross section, one for each direction travel. Occasionally, passing may be added or sides roadway extending section three four at those locations. In this entry, two-lane strictly roads rural areas meeting previous definition and do not include urban suburban streets.

Landscape patterns are closely related to ecological processes. Different spatial scales and research methods may lead to different results. Therefore, it is crucial to choose suitable research methods when studying different landscape patterns and ecological processes. In the present study, the methods of source-sink landscape theory were applied to the interactions between urban landscape cha...

Current analytical free-flow speed models consider all rural two-lane highways as the same road type despite their different functional significance in network. The aim of this paper is to develop a prediction model for function limit and geometric characteristics classes highways. research was conducted on 50 representative sections two equipped with automatic traffic counters Serbia. In order...

There are over 60,000 miles (100,000 km) of coastal highways in the United States (US) that occasionally exposed to waves and water levels. Wise stewardship calls for integration engineering principles practices planning design these roads bridges make them more resilient. A new, 3rd, edition primary guidance document Hydraulic Engineering Circular No. 25 (HEC-25), entitled “Highways Coastal En...

In August of 1997, The US National Automated Highway System Consortium (NAHSC) presented a proof of technical feasibility demonstration of automated driving. The 97 Demo took place on car-pool lanes on I15 in San Diego, California. Members of the Consortium demonstrated many different functions, including: Vision-based road following Lane departure warning Magnetic nail following Radar reflecti...

Cell-to-cell communication is a crucial prerequisite for the development and maintenance of multicellular organisms. To date, diverse mechanisms of intercellular exchange of information have been documented, including chemical synapses, gap junctions, and plasmodesmata. Here, we describe highly sensitive nanotubular structures formed de novo between cells that create complex networks. These str...

After the oocyte is fertilized, the resulting one-cell zygote gives rise to all stem cell progenies. During the developmental process, these cells are necessary to generate all specialized tissues. However, some of them elude the specification cues and remain quiescent in the adult tissue, as long as the organism does not suffer from injury, illness, or specific cell-type depletion. Most adult ...
