Centerline and Edge line Striping


Striping provides definition to a roadway and visually creates an effect of narrower travel lanes, which encourages drivers to slow down. It helps prevent encroachment into parking lanes, opposing travel lanes, and bicycle lanes. Field verification is necessary to determine if application is justified; no additional data or engineering design is required.


    Heightened awareness of travel space.

    Potential reduction in travel speeds between 1 and 5 mph where parallel parking is added to narrow travel ways and a reduction of 0.5 mph where shoulder markings are used.

    No impact to emergency vehicles.

    Low cost and fast to implement.

    Uses a standard traffic control device easily recognizable by motorists.


    Requires periodic maintenance/increased maintenance costs.

    Does not physically restrict vehicles.

    Limited effectiveness where setbacks create the perception of space.
