FDOT Context Classification

• Defines Approach, Process, Expectations, Best Practices

• Complete description of context classifications

What are the FDOT Context Classifications?

C1-Natural C2-Rural C2T-Rural Town C3R-Suburban Residential

C3C-Suburban Commercial

C4-Urban General

C5-Urban Center

C6-Urban Core

C1-NATURAL

Lands preserved in a natural or wilderness condition, including lands unsuitable for settlement due to natural conditions. Not intended for future development.

C2-RURAL

Sparsely settled lands; may include agricultural land, grassland, woodland, and wetlands. Lands that could be developed in the future.

C2T-RURAL TOWN

Small concentrations of town area immediately surrounded by ruraland natural areas; includes many historic towns.

C3R-SUBURBAN RESIDENTIAL

Mostly residentialuses within large blocks and a disconnected or sparse roadway network.

C3C-SUBURBAN COMMERCIAL

Mostly non-residential uses with large building footprints and large parking lotswithin large blocks and a disconnected or sparse roadway network.

C4-URBAN GENERAL

Mix of uses set within small blocks with a well-connected roadway network. The roadway network usually connects to residential neighborhoodsimmediately along the corridor or on the back side of blocks fronting the roadway.

C5-URBAN CENTER

Mix of uses set within small blocks with a well-connected roadway network. Typically concentrated around a few blocks and identified as part of a civic or economic center of a community, town, or city.

C6-URBAN CORE

Areas with the highest densities and building heights, and within FDOT classified Large Urbanized Areas(population >1,000,000). Many are regional centers and destinations. Buildings have mixed uses, are built up to the roadway, and are within a well-connected roadway network.

Context classification informs planners and engineers about the type and intensity of users along various roadway segments. For example, C4, C5, and C6 context classification will have

higher number of pedestrians, bicyclists, and transit users than in a C1, C2, or C3 context classification. C2T will be similar to C4.

WHAT DOES CONTEXT CLASSIFICATION TELL YOU ABOUT ROADWAY USERS?

Fundamentally, FDOT’s Complete Streets Approach is about linking

land use & transportation decisions/investments.

It is about putting the right street

in the right place.

A Context Based Approach

NATIONAL TRENDS AND RESEARCH

• 2008: > 5,000 pedestrian/bicyclist deaths and >120,000 injuries

• Pedestrian crashes are twice as likely in places without sidewalks

• Describes the conceptual underpinnings of speed management

• Introduces the concepts of • Enclosure• Engagement• Deflection

• Using these concepts, designers may be able to create additional speed management techniques to fit specific circumstances
