Pavement markings are installed to provide positive control guidance for the traveling public (pedestrians and bike riders) and are install using national standards from the MUTCD (Manual of Uniform Traffic Control Devices).
Marking Season and Methods of Installation
Marking season is warm dry weather, primarily from June to October. There are three methods of installation currently used by the PWM Traffic Maintenance team:
Latex, lead free paint using an airless paint sprayer used for yellow curb, parking lots, and temporary markings
Pre-form thermoplastic film is installed by hand using a propane torch for all wordage messages, bike symbols, arrows, crosswalks, stop bars and off season work
Long line spray thermoplastic for the skip lines, double yellow, bike lanes etc.
The Traffic Operations Section currently maintenance approximately 570 miles of roadway striping, 4,630 roadway legends and 743 marked crosswalks.
