Below is a listing of the types of cross-sections DDOT has collected.

Section Categories

Barriers

Barriers mark the end of a roadway feature. They separate the roadway from adjacent off-road features. (Note: Barrier data were not collected outside of the roadway (e.g. sidewalks).

Bike

Lane types designated for the use of bicycles, or the shared use of bicycles and vehicles

Buffers

A buffer separates lanes of traffic, opposing or non-opposing. If a curbed buffer has a painted buffer around it, then the entire area is measured and counted as a “Buffer.” If the surrounding painted buffer is obtrusive or prominent, then it is counted as its own separate feature.

Lanes

An active roadway with moving traffic. Lanes that intersect with access to driveways, alleyways, and shopping centers were not considered turning lanes for the purposes of this study. Turning lanes only exist when one roadway intersects another roadway. Lane designation is based on the main purpose of a lane during a 24 hour period (even if at some times in the day the designation is different).

Lines

A painted-on roadway feature separating lanes of traffic.

Parking

Lanes designated as parking are based on a visual assessment of whether or not parking is possible during any time period throughout the day.
