Title:
ROAD MARKINGS OF ROAD LANES (SOLID LINES, DOTTED LINES) FOR PREVENTING REVERSE DRIVING
Document Type and Number:
WIPO Patent Application WO/2021/225184
Kind Code:
A1
Abstract:
In every country, lanes constructed on roads refer to lines drawn at regular intervals along the driving direction on automobile roads. The present invention relates to a structure for effectively instructing normal driving by shaping the driving direction. In a manufacturing method thereof using existing products, it is difficult to manually set an exact point. As a result of testing by making a sample using only a push button (PB.push button), a timer device (T.Timer relay), a solenoid valve (SV.solenoid valve), and a nozzle, installing the product and interlocking with a constant speed driving device (cruise control) automatically enables precise construction at a required point. The lanes have a structure made up of dotted lines and solid lines, the lanes (dotted lines) have a shape of protrusions and depressions that is obtained by adjusting each nozzle injection time, and the lanes (solid lines) have characteristics that should lead to a lane change prohibited section, and thus have a structure in which an empty space creates a shape by temporarily stopping the injection time for each nozzle.
