What does the address component called street type refer to?

The address component known as street type specifically refers to the street suffix, such as Avenue, Boulevard, Street, Road, and others. This designation provides important information about the nature or classification of the roadway and helps in identifying the characteristics or purpose of the street. For example, an Avenue typically implies a larger street that may be lined with trees, while a Lane might suggest a smaller, more residential road. Including this information is essential for navigation, mapping, and addressing systems, as it helps distinguish between different types of streets within an area.

The other options focus on attributes that do not define the street type. For instance, street size pertains to physical dimensions, the street material relates to the construction of the roadway, and the number of vehicles per day addresses traffic volume, all of which provide context about the street but do not classify it in terms of the naming conventions that are intrinsic to address components.
