HIGHWAY ENGINEERING AND TRAFFIC ANALYSIS

INTRODUCTION OF HIGHWAY ENGINEERING AND TRAFFIC ANALYSIS :

Highways have played a key role in the development and sustainability of human civilization from ancient times to the present. Today, in the U.S. and throughout the world, highways continue to dominate the transportation system — providing critical access for the acquisition of natural resources, industrial production, retail marketing and population mobility.

The influence of highway transportation on the economic, social and political fabric of nations is far-reaching and, as a consequence, highways have been studied for decades as a cultural, political, and economic phenomenon. While industrial needs and economic forces have clearly played an important part in shaping highway networks, societies’ fundamental desire for access to activities and affordable land has generated significant highway demand, which has helped define and shape highway networks.

In the twenty-first century, the role of highways in the transportation system continues to evolve. In most nations, the enormous investment in highwaytransportation infrastructure that occurred in the middle of the last century, which included the construction of the U.S. interstate highway system (the largest infrastructure project in human history).HIGHWAY ENGINEERING AND TRAFFIC ANALYSIS

Has now given way to infrastructure maintenance and rehabilitation, improvements in operational efficiency, various traffic-congestion relief measures, energy conservation, improved safety and environmental mitigation. This shift has forced a new emphasis in highway engineering and traffic analysis — one that requires a new skill set and a deeper understanding of the impact of highway decisions.
