Are Solar Roadways Viable Technologies for the Future?

Solar roadway refers to road surfaces that are capable of generating electricity through photovoltaic solar power cells (Aggrawal, Mehta and Tiwari 161). One of the existing proposals involves the use of panels that encompass LED signage as well as solar panels that vehicles can be driven on. It is a concept that requires the replacement of roads, highways, sidewalks, driveways, and parking lots with the panels. The layers embedded with LED can be utilized for creating crosswalks and traffic warnings (Hartwig 1). Extra electricity can be used for charging electric vehicles or can be routed into the power grid. ...

Abstract

A dual carriageway is proposed to be constructed in the town moving in the east-west direction. The dual carriage is intended to be eight-kilometer long looping around the northern part of the town. Cut and fill techniques are used where half of the road is cut to a maximum of six meters. Half of the road is supported by an embankment of six meters high. At the eastern and western ends of the road are of grade where the road joins other roads and at the middle where the cut sections meet the filled sections. The road has a ...

I took the one less traveled by,

And that has made all the difference.

- Robert Frost, Road Less Traveled The journey to a destination is more important than the destination itself; this is a common understanding that has been accepted and acknowledged by all human generations that have lived on this Earth. The primary purpose of a road is to connect two places, serve as a mean of travel. But they have evolved much more than that; they connect people, societies, cultures, livelihoods. And for the traveler they are a source of inspiration. It is no wonder hence that the construction of roads and highways ...

Abstract

Experts tell that the twentieth century was the century of brutal man-made natural and environmental disasters. Often, we hear reports about falling missiles, planes, explosions on environmentally hazardous industrial objects, about the collapse of buildings. The main reasons of these tragedies are design errors related to insufficient knowledge of the laws of mechanics with the incorrect use of mathematical models. To prevent new disasters, we just need to look into the past and draw conclusions on the basis of the occurred accidents. Tacoma Washington Bridge Disaster (1940) Suspension bridges have a number of advantages in comparison with the ...

The renowned Steel Bridge is a double deck structure that has a vertical-lift and is also known as through-truss. It goes across the Willamette River in the city of Portland in the United States and was opened in 1912, so it recently celebrated its 100th anniversary. The bridge has the dual function of carrying rail and bicycle traffic on its lower deck whilst the upper deck is dedicated to road traffic. This innovative arrangement makes the bridge extremely innovative and the fact that it has an independent lift continues to emphasise its prominence as the second oldest vertical lift bridge in ...

Introduction

Charles Bridge of Prague in Czech Republic and the Golden Gate Bridge in United States are two of the most renowned bridges of the world. Both of these bridges exhibit few similarities and few differences in its physical form, location, types of users, frequency and purpose of use, and materials. This paper will elucidates and compare these similarities and differences. Not only these bridges have a sheer economic significance but they have great cultural impact, as well. Both were made for the same notion of connecting communities (Brook & Cornish, 1992). Charles Bridge was made a century ago, while Golden Gate Bridge, ...

Introduction Traffic control system is extremely important for any country because they help in regulating and directing a vehicle or pedestrian movement. This is especially important in areas where construction is underway; accidents can become a major cause or there is road diversion or disruption. Traffic control system ensures that active response teams are readily available, and rescue workers are available 24 hours a day in case of any emergency. Traffic control system has CCTV cameras deployed in different areas where they monitor the traffic control of especially heavy traffic movement ...

Adolf Hitler is the name that is connected with an image of a maniac; a man with direct responsibility for suffering, and death of millions of innocent people. Various studies that have been carried out throughout several years show that the barbarities committed by the Third Reich, and the immediate part of Adolf Hitler in the Final Solution seem to be broadly viewed as both the most vital, and most significant individual occasion in the present history. Despite the fact that a lot of researchers have given colossal deliberations in an endeavor to explain the actions of Adolf Hitler and collectively ...

Introduction:

Suspsension bridges have been around for quite a long time but the first one ever built was the Britannia Bridge which has been renamed as the Menai Suspension Bridge and is a suspension bridge which begins on the island of Anglesey and connects the mainland of Wales. The bridge was designed by the famed engineer Thomas Telford and was finished in 1826. It was described as the first modern suspension bridge in the world and won several plaudits upon its completion. It was described as a brilliant piece of engineering and daring which resulted in several other bridges following suit in later ...

Introduction

This report discusses the history of the Golden Gate Bridge, including the ferry services that preceded it (and resumed years later), when the bridge was built and opened, and the reason it was so named. It also provides some technical details of its construction.

History of the Ferry Service

Long before the Golden Gate Bridge was built, the only way for members of the public to cross San Francisco Bay was by ferries, which from 1850 provided a service between San Francisco and Oakland (“History of Golden Gate Ferry Service”, 2012). Then, according to the same article, a ferry service was started between Sausalito in Marin ...

Abstract The Brooklyn Bridge is probably underappreciated by most of the people who use it today but it is still an example of great engineering. The chief engineer, Roebling, designed a suspension bridge that was fifty percent longer than any other suspension bridge of the times. His design for weighting of the bridge to keep it stable when there was wind is a very important lesson for today’s suspension bridge designers. The health and safety issues of the height of the bridge and the use of the Caisson boxes have been discussed. The approximately 27 deaths that took place ...
