Highways are an essential component of our society because they are critical to quality of life and to local and national economies. Under good conditions, highways provide a safe and efficient route for people and goods to reach their destinations. However, as a direct consequence of their use, traffic congestion is ever-increasing, undermining the ability of highways to adequately provide an ...

Through utilizing US state-level data at annual frequency from 1976 to 2008, this paper documents a causal effect of infrastructure investments, specifically public spending on highways, on income inequality. The number of seats in the US House of Representatives Committee On Appropriations serves as a valid instrument to identify quasi-random variations in state-level spending on highways. Whe...

The design of efficient routing algorithms is an important issue in dense ad hoc wireless networks. Previous work has shown that benefits can be achieved through the creation of a set of data “highways” that carry packets across the network, from source(s) to sink(s). Current approaches to the design of these highways however require a–priori knowledge of the global network topology, with conse...

Tolls are a recurring but not continuous feature in major highway financing policy in Spain. User tolls were the model used to finance the first expansion of the highway network, in the 60’s and early 70’s. The second wave of the highway network expansion took place in the late 80’s and early 90’s. The public budget was the usual source of funds used to pay for the highways built in this period...

Sesame (Sesamum indicum L.) seed and oil have long been used widely as healthy foods to supply energy and prevent aging. Some of the main active anti-oxidative constituents in sesame seeds are γ-tocopherol and phenols. The purpose of this study was to investigate the relationship between roasting temperature and time with γ-tocopherol and total phenolic compounds (TPC) of sesame seeds when roas...

We consider a variation of Voronoi diagram, or time-based Voronoi diagram, for a set S of points in the presence of transportation lines or highways in the plane. A shortest time-distance path from a query point to any given point in S is a path that takes the least travelling time. The travelling speeds and hence travelling times of the subpaths along the highways and in the plane are differen...

This article quantifies the value of U.S. highways. We develop a multisector general equilibrium model with many locations in United States (i.e., counties) and countries. In model, producers choose shipping routes subject to domestic international trade costs, endogenous congestion, port efficiency at transshipment points. Applying we find that removing Interstate Highway System reduces real G...
