Road types can be categorized based on their function and design. Major categories include highways, which are designed for fast-moving traffic and have limited access points, and local roads, which provide access to homes and businesses. Other types include arterial roads, which connect major areas, and collector roads, which gather traffic from local streets and direct it to arterial roads. Additionally, roads can be classified by their surface materials. Asphalt and concrete are common surfaces for urban roads, while gravel or dirt roads are often found in rural areas. Each type of road serves specific purposes, impacting travel speed and accessibility.
