Entrance Capacity of an Automated Highway System

T his paper evaluates the entrance capacity and queueing delay for Automated Highway Systems through use of simulations and analytical modeling. Queueing statistics are also used to determine the sustainable capacity of alternative concepts, taking trip length distribution and spacing between ramps into consideration. Based on safety-spacing head­ ways (produced in a separate analysis), the mos...

Vascular Morphogenesis: An Integrin and Fibronectin Highway

A new study shows that endothelial cells use synaptic-like machinery to control polarized secretion and deposition of newly synthesised fibronectin. This process is coupled to active integrin recycling to the same locations and is fundamental for vascular development in zebrafish.

An Automated Snowblower for Highway Winter Operations

You pass by Donner Summit, on I-80, tires skidding slightly on the freshly plowed road.
