This document outlines the classifications of highways in both urban and rural areas. It describes the different functional classes including principal and minor arterials, collectors, and local roads. Principal arterials in urban and rural areas are designed for long distance travel and high speeds, while collectors and locals have shorter routes and focus on land access. Urban highways are further classified based on their role in carrying intra-city traffic and connecting to intercity routes. Freeways are fully limited access highways, while expressways have some access points but are also designed for high-speed travel.

boulevard, or parkway, available to the public
for use for travel or transportation.

6. FUNCTIONAL CLASSIFICATION

7. Urban Functional System
• Functions: carry most trips
entering/leaving urban area, serve intra-
urban trips, carry intra-urban and intercity
bus routes, provide continuity to rural
arterials
Principal Arterials
• Characteristics: longest distance
routes and highest volume, high
speed, spacing is less than 1 km in
CBD and greater than 8 km in urban
fringe, full/partial access control

8. Urban Minor Arterials
• Functions: interconnect with and
augment principal arterials,
accommodate moderate length trips,
distribute traffic, carry local buses,
provide intra-community continuity,
connect to urban collectors
• Characteristics: moderate trip length
high volumes, moderate speeds,
spacing 0.2 to1.0 km in CBD and 3 to
5 km in suburbs

9. Urban Collectors
• Functions: Provide traffic circulation within
residential neighborhoods and
industrial/commercial areas, collect traffic from
locals and channel to arterials, carry local buses,
provide some direct land access.
• Characteristics: Shorter than minor arterials,
moderate speeds, spacing intermediate to
arterials, penetrates residential neighborhoods.

10. Urban Locals
• Functions: Provide direct access to
land, connect properties to higher
class streets (i.e., collectors).
• Characteristics: Short in
length, dead end –
terminate at collectors,
low speeds, no bus
routes.

11. Rural Functional System
Rural Principal Arterials
• Function: Statewide/Interstate Travel and
Connect urbanized areas.
• Characteristics: Long trips, no stubs, high
speed, widely spaced, full/partial access control.

12. Rural Minor Arterials
• Function: intrastate/inter-county trips, connect
small urban areas with major trip generators.
• Characteristics: Moderate everything (routes,
speed, spacing, mostly mobility)

13. Rural Collectors
• Major Collectors: Connect
county seats to large towns
not served by arterials, link
entities with nearby
arterials, urban areas.
• Minor Collectors: Serve
remaining small towns, link
local traffic generators with
rural areas
• Characteristics: Shorter,
Moderate Speeds (in rural
areas), Intermediate
spacing.

14. Rural Local Roads
• Function: Provide access to
land on collector network,
serve short distance travel.
• Characteristics: Short routes that
terminate at higher classes,
relatively
low speeds, intermediate spacing.

15. • This designates roadways with greater visual
complexity and high traffic volumes. Usually this
type of freeway will be found in metropolitan
areas in or near the central core.
• Freeway is a common name for different types
of limited access highways.
Freeway

16. • Expressway is the equivalent of what used to be
called "Limited Access Roads". These roads may
have some interchanges or stop signs where
local roads connect to it.
Expressway
• Expressway have a partial access control
• a broad highway designed for high-speed
traffic.
