Please use the following organization names, abbreviations, and acronyms. Note that terms such as AADT (annual average daily traffic), PCC (portland cement concrete), dpi (dots per inch), and many more are common nouns, and are thus lowercase when spelled. Keep common nouns in mind when deciding whether to use uppercase or lowercase.
