Roads play a vital part in the function of almost every society and efficient road systems are needed to transport everything from foodstuffs for supermarket shelves, ore from mine sites, agricultural goods from farms, and people to and from work and leisure activities.
Highway engineers plan, design and maintain safe, efficient roads, highways and public transit systems. They specialise in analysing population and growth statistics, traffic patterns and volume to project future requirements. Highway engineers work closely with government officials and other specialists to help design efficient and safe traffic systems. Highway engineers also study roadway and embankment design, the geometry of highway interchanges and the maintenance of facilities such as culverts and overpasses.
