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@example.com.
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” available from the Planning and Development Services Department.
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.
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.
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 Classifications of Pavement Markings
- 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
- A dotted line provides guidance or warning of a downstream change in lane function.
Widths and Patterns
- A normal width line is 4”.
- 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.
These are lines that generally run parallel to the direction of traffic and include:
- Solid double centerlines
- Broken centerlines
- Solid and broken centerlines
- Broken lane lines
- Solid lane lines
- Broken lane extension lines
- Edge lines
- Solid lane lines
- Lane drop lines
- Bicycle lane lines, etc.
These are lines that generally run perpendicular to or at an angle to the direction of traffic and include:
- Diagonal crosshatch lines
- Stop lines
- Crosswalk lines
- Roundabout extension edge lines
- Perpendicular or angled parking space lines, etc.
Symbol markings are all other markings that are not considered “lines” but consist of geometric shapes or words. They include:
- Yield lines
- Turn arrows, thru arrows, or combination arrows
- Merge arrows
- Railroad crossing markings
- ONLY markings
- Bicycle lane symbols
- Bicycle lane arrows
- Sharrow markings
- International symbol of accessibility, etc.
Types of Pavement Markings
There are several different types of pavement markings applicable to specific situations. The City of Overland Park has specific design considerations that should be reviewed for each type of pavement marking.
Yellow Centerline Markings
Yellow centerline markings are used to delineate the separation of traffic lanes that have opposite directions of travel. They are used on thoroughfare roadways, collector roadways, and super collector roadways regardless of the posted speed. Centerline markings are not installed on residential roadways except in specific situations in advance of intersections as addressed below.
The yellow centerline markings, whether broken or solid double lines, should be continuous through residential drive entrances and alleys but should break at intersections with public streets and private streets as defined above. Breaks in the centerline should not be made at single family or multi-family drive entrances. They should also not be broken at intersections with commercial drive entrances unless the main roadway has left or right turn lanes accessing the site or the intersection with the commercial drive is controlled by a traffic signal.
At breaks in the centerline, the beginning and end of the centerline should be evaluated based on the left turn movement of the design vehicle from the side street. The beginning or end of the line should be at the point where the design vehicle does not drive over the line while making a left turn. This should be determined using turning movement templates for the specific design vehicle.
Centerlines on Residential Streets
Centerlines are not typically installed on residential streets. However, when a residential street has more than two or more approach lanes to an intersection that are marked with solid white lane markings, a double yellow centerline should be installed in advance of the stop line for a minimum of 50’ or for the length of the solid white lane markings.
At a multi-way stop-controlled intersection between two residential streets, a solid double yellow centerline shall be installed starting a minimum of 50’ in advance of the stop line on all approaches.
Centerlines on Collector Streets
All two-lane collector streets, regardless of width, shall be striped with a centerline consisting of a 4” wide broken yellow line with a 6’ stripe and an 18’ gap (3:1 ratio). Collector streets that consist of more than two lanes shall be striped with a 4" solid double yellow centerline.
See the section on Transitions from Broken Yellow Centerlines below for treatment of centerlines at intersections.
Centerlines on Apartment Streets
Apartment streets that are 36’ wide (measured from back of curb to back of curb) and where the posted speed is 30 mph, a centerline should be striped. It shall consist of a 4” wide broken yellow line with a 6’ stripe and an 18’ gap (3:1 ratio).
However, when an apartment street, that qualifies for a centerline, has more than one approach lane to an intersection that is marked with solid white lane markings, a double yellow centerline should be installed in advance of the stop line for a minimum of 100’ or for the length of the solid white lane markings.
At a multi-way stop controlled intersection with two apartment streets, a solid double yellow centerline shall be installed 100’ in advance of the stop line on all approaches.
Centerlines on Commercial and Industrial Streets
Commercial streets or industrial streets may range in width from 36’ to 52’ (measured from back of curb to back of curb) to accommodate left or right turn lanes or additional through lanes for added vehicle capacity. Centerlines should consist of 4” wide broken yellow lines with a 6’ stripe and an 18’ gap (3:1 ratio) or 4” solid double yellow lines depending on the number of lanes. Broken yellow centerlines would be used where there are no auxiliary lanes such as right or left turn lanes. Double yellow centerlines should be used at multi-lane cross-sections and may terminate at an intersection with a painted median. Depending on the number of access points, a two-way left turn lane may be provided as approved by the City Engineer. Painted medians and two-way left turn lanes are discussed below.
Centerlines on Super-Collector Roadways
Super-collector roadways range from two undivided through lanes that are 36’ wide (back of curb to back of curb) similar to a residential-collector roadway, to divided roadways with four through lanes. Centerline pavement markings should either be 4” wide broken yellow line with a 6’ stripe and an 18’ gap (3:1 ratio) or 4” solid double yellow lines depending on the number of lanes. Broken yellow centerlines would be used where there are no auxiliary lanes such as right or left turn lanes, while double yellow centerlines should be used at multi-lane cross-sections. Proper transitions between broken centerlines and painted or raised medians should be provided as discussed in “Transitions from Broken Yellow Centerlines” below. Depending on the number of access points, a two-way left turn lane may be provided as approved by the City Engineer. Two-way left turn lanes are discussed below.
Centerlines on Thoroughfare Roadways
The following guidelines are established for centerline pavement markings on thoroughfare roadways, consisting of divided or undivided roadways and improved or unimproved roadways. Undivided thoroughfare roadways fall into two categories: 1) unimproved and 2) improved.
Unimproved thoroughfares have two through lanes of traffic that have not been widened. These primarily exist in the southern portions of the City that have been taken over from the County through annexation and where development has not fully occurred to require the roadway to be widened due to increased traffic volumes.
Improved thoroughfares have been widened to provide for at least two lanes of through traffic with shoulders and sometimes four lanes of through traffic. The two-lane or the four-lane thoroughfares may be divided or undivided.
Centerlines on Divided Thoroughfare Roadways
Divided thoroughfare roadways that have a continuous median, except for breaks at approved intersections, do not require centerline pavement markings if the center median consists of raised curbs. When the center median is depressed, the centerline pavement marking should consist of a single 4” solid yellow edge line on each side of the depressed median. The yellow edge line should be installed 4” from the edge of the driving surface to the closest edge of the line.
Thoroughfares with intermittent raised medians shall have a 4” solid double yellow centerline in those sections that do not have a center median. Any time a raised median section is provided, centerline markings are not required. Proper transitions between broken centerlines and painted or raised medians should be provided as discussed in “Transitions from Broken Yellow Centerlines” below.
Centerlines on Undivided, Improved Thoroughfare Roadways
Undivided, improved thoroughfare roadways should consist of 4” solid double yellow centerlines. Depending on the number of access points, a two-way left turn lane may be provided as approved by the City Engineer. Two-way left turn lanes are discussed below.
Centerlines on Undivided, Unimproved Thoroughfare Roadways
Undivided, unimproved thoroughfare roadways should always consist of 4” solid double yellow centerlines. Passing is prohibited on these types of roadways.
Transitions from Broken Yellow Centerlines
Transitions often occur from a broken yellow centerline to double yellow centerlines. The following discussion provides guidance in the design in various applications.
Prior to Raised or Painted Medians
When transitioning from a broken yellow centerline to a raised or painted median, the raised or painted median should be preceded by a double yellow centerline a minimum of 100’ in length unless there is some engineering reason that limits it to less than 100’, e.g. another intersection. This length should be increased if it places the beginning of the double yellow centerline near the blind side of a crest vertical curve.
