In addition to grabbing a drivers attention, this traffic calming measure consists of painted markings which progressively decrease in spacing to create the illusion of increased speed, which causes the driver to slow his speed.
Traffic Markings - Transverse Markings
Traffic Markings - Shark Tooth Markings
This unique marking pattern has been tested in case studies to show that it does indeed slow on average 19% of all speeders. The illusion created by the 'shark teeth' not only makes it appear as if a driver is going faster that he or she really is, but it also makes it appear as if the street is narrowing, causing drivers to slow down.
Streetprinting or asphalt stamping is a cost effective way to pave intersections and crossing which appear to be brick-laid and/or raised, while actually being colorized asphalt. The textured/colored appearance warns the driver of a 'multi-use' zone or area, causing them to be more vigilant of their surroundings and to ultimately slow down.
Textured Pavement - Stamped/Painted
Textured pavement gives drivers a visual and physical warning to be aware of their surroundings and to slow their vehicles - a change in texture encourages attention.
Textured Pavement - Rumble Strips
Rumble strips/markings promote slower speeds by physically warning the driver of upcoming speed zones and limits. They are very effective and are very diverse in their applications and appearance.
