We present a method to predict the time thatwill be needed to traverse a certain stretch of freeway whendeparture is at a certain time in the future. The predic-tion is done on the basis of the current traffic situation incombination with historical data.We argue that, for our purpose, the current situation of astretch of freeway is well summarized by the ‘current status...

Automatic vehicle classification (AVC) systems provide information about classes of vehicle that can be used for many purposes. This paper describes a axle count and axle spacing using wireless accelerometers sensors and magnetometers sensors. The vehicle axles are detected by accelerometer sensors, and the vehicles arrivals, departures and speed are estimated by magnetometers. The prototype sy...

There is little doubt that those of us who are involved in the great industry of motor vehicle transportation—whether it be along the lines of design, maintenance, or operations—have come to recognize that street and highway capacity considerations are indispensable. It is unfortunate, however, that too often there is a lack of clear understanding of what we mean by capacity and how it actually...

Stimulating economic growth and development in rural and economically lagging regions is the goal of several federal and state highway programs. This paper examines the effectiveness of highway investment as an economic development tool. A quasi-experimental matching method is used to examine the effects of interstate highways on counties which obtained links during the period 1963-75 or are in...

Membrane trafficking, or the flow of membrane material between endomembrane compartments and the plasmalemma, is essential for transport of proteins and other macromolecules to various destinations inside and outside of the cell. Membrane trafficking also underlies the fundamental need for cells to maintain cellular homeostasis, as well as to meet specific demands during signal perception and t...
