RUAS

Ruas is a term used in Indonesian and Malay languages meaning a segment or section of a larger linear object. It is commonly applied to infrastructure, where ruas denote a defined stretch of roadway, railway line, river reach, or utility corridor between two junctions, landmarks, or boundary points. In road transport and planning, ruas jalan or ruas tol refers to one such stretch and is used for inventory, maintenance scheduling, traffic counting, and project planning. Agencies may assign a code to each ruas for management.

In mapping and GIS, ruas serve as the basic unit for indexing and analyzing road networks; data are often stored at the ruas level to compute metrics like traffic volume, condition, or accessibility.

The term is primarily used in Indonesian and Malaysian contexts, though related cognates exist in other Malay-speaking regions. As a general word, ruas can also appear in compound nouns describing segments of other linear features, such as ruas sungai (river reach) or ruas kereta api (railway segment).

Ruas is not typically used as a standalone English term, but in regional planning and transport documents it functions as a practical unit of reference. The term may also appear as part of proper names or toponyms in some localities, where it carries no special technical meaning beyond its usual sense of "section" or "stretch."
