Highway engineering is an engineering discipline branching from civil engineering that involves the planning, design, construction, operation, and maintenance of roads , bridges , and tunnels to ensure safe and effective transportation of people and goods. Standards of highway engineering are continuously being improved. The beginning of road construction could be dated to the time of the Romans. The construction of modern highways did not begin until the late 19th to early 20th century. The first research dedicated to highway engineering was initiated in the United Kingdom with the introduction of the Transport Research Laboratory TRL , in With technology out of date, in the construction of the first motorway in Great Britain the Preston bypass played a major role in the development of new pavement technology. Highway planning involves the estimation of current and future traffic volumes on a road network.

In general, transport projects that improve overall accessibility i. Many economic impacts are economic transfers one person, group or area benefits at another's expense while others are true resource changes overall economic productivity increases or declines. In many situations, the distribution of impacts is important; for example, from the perspective of the people who gain from an economic transfer, it is a true benefit, but not from society's overall perspective. It is important to consider the full range of economic impacts, both positive and negative, that a transport project may cause.
The development of transportation systems is embedded within the scale and context in which they take place, from the local to the global and from environmental, historical, technological, and economic perspectives. Development can be defined as improving the welfare of a society through appropriate social, political, and economic conditions. The expected outcomes are quantitative and qualitative improvements in human capital e. The development of transportation systems takes place in a socioeconomic context.

Roads make a crucial contribution to economic development and growth and bring important social benefits. They are of vital importance in order to make a nation grow and develop. In addition, providing access to employment, social, health and education services makes a road network crucial in fighting against poverty. Roads open up more areas and stimulate economic and social development. For those reasons, road infrastructure is the mo. Road repairs are crucial to optimising safety for the road network. For those reasons, road infrastructure is the most important of all public assets.
Transport decisions in an age of uncertainty pp Cite as. In developing countries investment in rural and inter-urban roads continues to represent a large part of national development programmes. It is therefore important that decisions about such investments are made on the basis of the best possible information. The economic consequences of building roads to particular geometric and structural standards are rarely adequately investigated at project appraisal stage, largely because knowledge of the interaction between the various factors involved is very limited.
Двое суток встроенные часы устройств обменивались бесконечными потоками зашифрованной синхронизирующейся информации. АНБ, перехватывая эти информационные импульсы, игнорировало их, считая аномалией сети, безобидной тарабарщиной. Но когда ТРАНСТЕКСТ расшифровал эти потоки информации, аналитики тут же увидели в них синхронизированный через Интернет отсчет времени.
