Markings on highways and on private roads open to public travel have important functions in providing guidance and information for motorists and pedestrians. Major marking types include:
Channelizing devices and islands
Pavement and curb markings
In some cases, markings are used to supplement other traffic control devices such as signs, signals, and other markings. In other instances, markings are used alone to effectively convey regulations, guidance, or warnings in ways not obtainable by the use of other devices.
As the third largest Highway Department in New York State, the Brookhaven Highway Department maintains nearly 3,500 lane miles of road annually. This includes re-striping newly paved roadways and maintaining pavement markings on existing roadways.
