Pavement Marking Design Manual

General Purpose of the Design Manual:

Last Revised 6/20/19
This Pavement Marking Design Manual has been written to serve as a general guideline when designing pavement markings for the City of Overland Park, Kansas. Although there are specific design requirements, the guidelines contained herein should not be a substitute for proper engineering design and judgment based on specific situations. All pavement markings shall comply with the latest adopted edition of the Manual on Uniform Traffic Control Devices (MUTCD). The purpose of this Pavement Marking Design Manual is to aid consultants as well as City of Overland Park staff to be consistent in the practice of designing pavement marking plans. It provides an overview of what tasks are expected to be included in the scope of the design; what information should be included on the plan sheets; what kind of backup design information is required; and what is expected for the final deliverable product. Any questions regarding this manual may be directed to Bruce Wacker, P.E., Assistant City Traffic Engineer at the City of Overland Park, Kansas at (913) 895-6027 or by email at [email protected].

Purpose of Pavement Marking:

Pavement marking provides guidance and information to the roadway user as well as supplement other traffic control devices such as signs, traffic signals and other markings. Pavement markings can convey regulations, guidance, or warnings.

Wherever applicable, this design manual should be used in conjunction with the latest adopted edition of the Manual on Uniform Traffic Control Devices (MUTCD) by the Federal Highway Administration. The current editions of the Design and Construction Standards, Volume 2 Construction Specifications (latest edition), the latest edition of the Standard Details and the Approved Materials List, hereafter referred to as “City Standards” should be followed during the design of all pavement marking plans.

Public or Private Ownership and Maintenance

Different policies apply to pavement marking based on the final ownership and maintenance. The two types of pavement markings are 1) those that are installed in the public right-of-way that will be owned and maintained by the City of Overland Park and 2) privately owned pavement markings that are installed on private property that will not be maintained by the City of Overland Park. Although each of the categories will be discussed, the design guidelines contained herein only apply to pavement markings that are within the public right-of-way or other City easements that are owned and maintained by the City of Overland Park.

City-Owned and Maintained Pavement Markings

All City-owned and maintained pavement markings shall be designed in accordance with the design criteria listed herein and use all pre-approved materials from the City’s Approved Materials List, which is available at City Hall or from the City’s web page. All pavement markings that are being designed in conjunction with the development of any public street or any developments that require modification of any pavement marking within the public right-of-way or other City easements by private consultants working for a developer are required to meet City Standards.

Privately Owned and Maintained Pavement Markings

A private street as defined, in City Resolution 4065, means a right-of-way which affords principal access to property abutting thereon, which right-of-way is owned, controlled and maintained by persons other than the public, which is named in accordance with the street name designated system on the City map and signed in accordance with Chapter 13.10 of the Overland Park Municipal Code. It is generally owned and maintained by a homes or business association or private citizens. The private streets are designated by a “Private Street” sign at the point of entry and typically have street name signs.

All pavement markings on private property are not required to be constructed using City approved materials. However, pavement markings on the approaches of a private street or drive that tie into City streets shall be designed to conform to these guidelines and the MUTCD. The City may make requests to the owners to maintain private pavement markings from time to time in order to improve visibility, reduce driver confusion, or to coordinate with lane use changes that would affect the traveling public in conjunction with the lane use on adjacent public roadways.

Functional Roadway Classifications

The following pavement marking design criteria will be used for all thoroughfare roadways, super collector roadways, collector roadways and residential roadways as identified on the latest edition of the City of Overland Park “Official Street Map” as well as the “Future Development Master Plan” available from the Planning and Development Services Department.

Thoroughfare Roadway

The thoroughfare roadway classification includes all thoroughfare roadways whether divided or undivided; whether improved or unimproved; and whether two-lane, four-lane or six-lane excluding auxiliary left and right turn lanes; regardless of the volume of traffic.

Collector Roadway

The collector roadway classification includes all super-collector and collector roadways regardless of the number of lanes; whether improved or unimproved; regardless of the volume of traffic.

Residential Roadway

The residential roadway classification includes all local residential and cul-de-sac roadways; whether improved or unimproved; regardless of the volume of traffic.

Colors of Markings

Markings shall be either white or yellow and conform to the standard highway colors.

White Pavement Markings

White markings, when used for longitudinal lines shall delineate the separation of traffic flows in the same direction or the right-hand edge of the roadway. White markings shall also be used for crosswalk lines, stop lines and pavement marking symbols, with the exception of the symbol of accessibility and interstate route shields, etc.

Yellow Pavement Markings

Yellow markings, when used for longitudinal lines shall delineate the separation of traffic traveling in opposite directions; the left-hand edge of the roadway or divided street or one-way streets; and the separation of two-way left turn lanes.

Function, Widths and Patterns of Pavement Markings

Function

A double line indicates maximum or special restrictions and does not allow any crossing of the line. A single solid line discourages crossing. A broken line indicates a permissive condition and a dotted line provides guidance or warning of a downstream change in lane function.

Widths and Patterns

• A normal width line is 4” and a wide line is twice the width of a normal line, or 8”.
• A double line consists of two parallel lines separated by a 4” space (measured from edge of line to edge of line).
• A broken line consists of a normal line segment separated by gaps.
• A dotted line is a noticeably shorter line segment separated by shorter gaps than used for a broken line. The width of a dotted line extension shall be the same width of the line it extends.

Classification of Markings

Markings are either classified as longitudinal, transverse, or symbols.

Longitudinal Markings

These are lines that generally run parallel to the direction of traffic and include:

1. Solid double centerlines
2. Broken centerlines
3. Solid and broken centerlines
4. Broken lane lines
5. Solid lane lines
6. Broken lane extension lines
7. Edge lines
8. Solid lane lines
9. Lane drop lines
10. Bicycle lane lines, etc.

Transverse Markings

These are lines that generally run perpendicular to or at an angle to the direction of traffic and include: 1) Diagonal crosshatch lines, 2) Chevrons, 3) Stop lines, 4) Crosswalk lines, 5) Roundabout extension edge lines, 6) Perpendicular or angled parking space lines, etc.

Symbol Markings

Symbol markings are all other markings that are not considered “lines” but consist of geometric shapes or words. They include: 1) Yield lines, 2) Turn arrows, thru arrows, or combination arrows, 3) Merge arrows, 4) Railroad crossing markings, 5) ONLY markings, 6) Bicycle lane symbols, 7) Bicycle lane arrows, 8) Sharrow markings, 9) International symbol of accessibility, etc.
