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
