Table 4-1. Road Classifications and Their Characteristics

Classification Primary Function Examples 2010

Centerline Miles

a

Freeway

Carries through traffic across

the community. Provides most

mobility and least amount of

access.

Minnesota Drive; Glenn

and Seward highways 51

Freeways serve the sole purpose of carrying through traffic. They accommodate high

speeds and limited access, provided by only grade-separated interchanges, which also

provide a safety benefit by reducing crashes. The typical ADT volume of a four-lane

freeway is more than 40,000 vehicles.

Expressway

Carries through traffic. Provides

high mobility and somewhat

restricted access.

International Airport

Road between Minnesota

Drive and Ted Stevens

Anchorage International

Airport

2

Expressways accommodate through traffic with full or partial control of access.

Intersections may allow access from major arterials. Speeds typically are slower than

those for freeways. The typical volume of a four-lane expressway is more than 20,000

ADT.

Arterial

Carries large volumes of traffic

and goods, generally from one

part of the community to

another. Provides moderate to

high levels of mobility and

access.

Tudor Road, Northern

Lights Boulevard, 36th

Avenue, the Old Glenn

Highway in Eagle River,

and Eagle River Road

174

Arterials handle the largest share of travel in the Anchorage metropolitan area. They

connect major employment centers, activity centers, and residential areas. The typical

volumes range from 10,000 ADT for a two-lane (minor) arterial to 60,000 ADT for a six-

lane (major) arterial.

Collector

Collects traffic from local streets

and conducts it to arterials,

other local streets, and activity

centers. Provides limited

mobility and high level of

access.

Baxter and Wisconsin

roads, Hillside Drive, and

Business Boulevard

149

Collectors accumulate traffic from local streets and provide connections to shopping

centers, schools, and other commercial and community centers. The typical volumes

range from 2,000 to 10,000 ADT for a two-lane collector.

Local street

Allows access to adjacent

properties. Provides the highest

level of access.

Streets in neighborhoods 1,130

These roads specialize in connecting residential properties to other parts of the roadway

network. Speed limits are low and through travel is discouraged. The typical volume of a

two-lane local street is less than 2,000 ADT.

aThe centerline mile measurement is used for comparison purposes. This unit of measurement reflects distance as the sole measurement and does not account for multiple lanes. ADT = average daily traffic Source: Official Streets and Highways Plan, MOA, 1996.

The time spent by vehicle occupants is not the

only concern when roads and intersections

perform at a poor level of service. The flow of

traffic also affects travel time required for public

transportation, school buses, freight shipments,

and emergency service response. Delays can

drive up the cost of shipping, hinder fire truck

and ambulance access, and affect coordination

of scheduled activities.

and Service Delivery

weather encountered that year.
