Ever since the early 1900s, the United States has been a nation of cars. There was a renewed interest in such vehicles in the 1920s, and by the 1950s, cars had become commonplace, along with the highways and roads that they drove on. All of this requires serious feats of traffic engineering, and today, civil engineer services are ready and willing to get to work all around the world. Engineering projects to create safer and better highways can improve traffic flow and reduce rates of traffic jams, auto accidents, and other undesired events. Today’s technology such as lidar surveying and photogrammetry allow a civil engineering company to mare accurately scan existing highways and make 3-D maps of them. Traffic engineering can use similar scanning methods to make 3-D maps of other terrain when a highway is being planned for construction. In fact, the same may be said about other civil engineering p
