Tom Williams posted this video on Vimeo where he happened to catch two workers early morning doing street typography. Typography is defined as the art of arranging letters for the onlookers to make sense and look considerably legible. These road surface marking are utilised to convey official information; when to stop and where to go or inform motorists and pedestrians about directions etc.
Paint with additives such as retroreflective glass beads is used to mark travel lanes. Painted symbols, such as turn-lane arrows or HOV lane markers, are applied manually using stencils. Painted markings usually last 9 to 36 months.
