Street Typology

Previous functional classifications of streets provided a hierarchy that correlated traffic flow to land access. Traffic volume, speed, and level of service provided the basis for design criteria. This classification system fell short in the consideration of other users of the public right of way (pedestrians, bicyclists, and transit) and was void of context for how adjacent land uses impacted the street and vice versa. This new Street Typology does not abandon the previous classification method but augments it with new, user-oriented considerations moving beyond considering the street system as a mere conveyance of automobiles.

When designing roads, focusing only on traffic volume and speed is less productive than a contextual approach that considers nearby land uses, multiple user groups, and the creation of a sense of place. This contextual approach makes the street compatible with the surrounding uses, enhancing the value of each. Safety of all users is increased by using design that accommodates everyone. Efficiency is increased by aligning resources with street design that reflects the intended intensity of use.

Street Types

The planokc Street Typology includes the following eight types:

  1. Major Arterials
  2. Minor Arterials
  3. Connector
  4. Neighborhood
  5. Main Street
  6. Rural
  7. Industrial
  8. Downtown

Guiding Principles

  • Recognize the inextricable relationship of streets and the adjacent land uses, integrating existing and future land uses to design appropriate streets, and vice versa;
  • Ensure the needs of all users are balanced;
  • Integrate alternative modes of transportation, such as transit and bicycles;
  • Improve safety for all users, regardless of mode;
  • Improve connectivity and circulation; and
  • Provide adequate facilities for active transportation to improve public health throughout the city.

 

Major or Minor Arterial

LUTAs: UL, UM, UH, DT, ER, UR, HI

Description: Moving people across the city is the priority of the arterial system. Arterial streets need to accommodate through traffic, access to adjacent uses, and connections to the highway system. At the same time pedestrians, bicyclists, and transit users must be considered. Good access management needs to be utilized to protect traffic flow and increase safety. The interaction between the arterial and the abutting lower intensity districts will be determined by how other street types connect to the arterial system. How this interaction is achieved is key to ensuring land uses work together.

Priority Design User: Traffic flow and connectivity are the primary functions of the Arterial. Sidewalks should be separated from the roadway to the greatest degree possible. Bicycles should be accommodated with dedicated space such as cycle tracks or trails, or provided for on alternative routes.

Access Management: Access management techniques that improve the function of intersections (eliminating driveways from the functional portion of the intersection, median-controlled left hand turns, adequate throat lengths into parking lots, etc.) should be utilized. Where possible, driveways should be shared to reduce the number of collision points and reduce potential congestion problems.

Connector

LUTAs: UL, UM, UH, DT, ER, UR

Description: Connectors are the streets that move people through and between their neighborhoods. They connect to surrounding areas and uses, and become a secondary network of streets to the arterial system. Connectivity is important for all street types, but imperative for the Connector as it creates an opportunity for pedestrians and bicyclists to use a corridor separate from higher volume streets.

Priority Design User: Pedestrians and cyclists should be accommodated by creating slow vehicular travel speeds. Bike infrastructure could include lanes or sharrows. Safe pedestrian crossings should be achieved through well demarcated crosswalks, bulb-outs, and signage. Intersections with arterials need to be designed for safe pedestrian and bicycle traffic.

Access Management: Driveway cuts should be kept to a minimum while allowing local access to adjacent residential, commercial, or industrial development.

Neighborhood

LUTAs: UL, UM, UH, RM, RL

Description: These streets primarily serve residential uses. However, street and neighborhood character can vary dramatically between very urban (Urban High), suburban (Urban Low), and rural contexts. Regardless of the context, neighborhood streets are meant to move people to and from the places they live. But more than that, they are the public realm in which the social interactions occur that make a neighborhood more than a collection of houses. Efforts should be made to ensure that traffic moves at a slow pace, that connectivity is promoted, and the character of the street is a noticeable benefit to the people who live there.

Priority Design User: Pedestrians should be accommodated by creating slow vehicular travel speeds. Safe pedestrian crossings should be achieved through well demarcated crosswalks, bulb-outs, and signage. Bicycles can be accommodated in the travel way intermixed with slow moving traffic.

Access Management: Local access should be provided to adjacent residential, commercial, or industrial development.

Main Street

LUTAs: UM, UH, TO, RD

Description: Main Streets contain a mix of activities and are defined by the character of the district surrounding them. Generally they are the streets on which a person could live, work, and shop. Because they touch so many varied uses they have to comfortably accommodate a multitude of users, including pedestrians bicyclists, transit riders, and drivers.

Priority Design User: The priority consideration in design should be pedestrians. As such, blocks should be shorter and there should be a high level of connectivity. The pedestrian zone should be generous containing safe and inviting sidewalks with emphasis placed on safe crossings when traversing from one side of the streets to the other. Street design that accommodates low-speed traffic through the use of bulb-outs, reduced curb returns and narrow widths on the vehicle travelway should be the norm.

Access Management: High level of access management required to preserve the pedestrian environment and maintain reasonable traffic flow.

Rural

LUTAs: RM, RL, UR, AP

Description: Rural streets serve low density areas and are typically two-lane section line roads. It is anticipated that no widenings of these roads would occur until such a time the LUTA is changed to a higher intensity. Often capacity can be increased on these roadways by improving the surface materials.

Priority Design User: The majority of trips on rural roads will be by automobile. Cyclists and pedestrians can be accommodated with the use of wide shoulders.

Industrial

LUTAs: UL, UM, UH, UR, ER

Description: Uses along industrial streets are unique. Streets associated with this use must move goods and materials on large vehicles while being connected to the arterial and highway systems. Design considerations include larger curb radii and wider lane widths.

Downtown

LUTAs: UH, DT

Description: Downtown Oklahoma City requires a special Street Typology that accommodates high volumes of pedestrian and transit activity. For the appropriate typologies related to Downtown, refer to the Downtown Development Framework document.

Access Management

Access management is the systematic control of the location, spacing, design, and operations of driveways, median openings, interchanges, and street connections to a roadway.

The purpose of access management is to provide vehicular access to developed land in a manner that preserves the safety and efficiency of the transportation system.

Within the context of street typologies, access management should be a guiding principle, the details of which will be addressed as a roadway is built, reconstructed, or otherwise improved. The land use context, the functional intent of the road, and the engineering constraints of each project influence the specific access management techniques for any given project. Some areas of Oklahoma City have been prioritized for access management improvements as described in the Access Management Focus Areas section.


Balance of Users
One of the guiding principles of the Street Typology is to ensure that the needs of all users are balanced, including automobiles, pedestrians, bicyclists, and transit-riders.
Street Typology Map
Additions
These streets are expected to need major improvements in capacity for one or more modes of travel in the foreseeable future. The upgrades made, and timing of the improvements, will affect the desirability and timing of adjacent development.
Alterations
These streets are currently built with more capacity than will be needed or with excess capacity for one mode of travel and insufficient capacity for other modes. On these streets only minor improvements are needed, in some cases restriping to allocate the space on the roadway differently.
