Highway systems are networks of roads designed for fast and efficient transportation of vehicles over long distances. They typically feature multiple lanes, limited access points, and higher speed limits compared to regular roads. These systems are crucial for connecting cities, facilitating trade, and enabling travel. In many countries, highway systems are maintained by government agencies and funded through taxes and tolls. They often include features like rest areas, signage, and interchanges to improve safety and navigation. Examples of highway systems include the Interstate Highway System in the United States and the Autobahn in Germany.
