During driving one of the basic tasks of the driver is to follow the traffic route in such a way as not to endanger in the process other traffic participants. In order to improve the driving safety, the manufacturers install new safety systems in the cars. Thus, the safety system ILAS (Involuntary Lane-crossing Alert System) warns the drivers of the unintended and incorrect crossing of the full or broken line during driving. The proper functioning of ILAS requires high quality road markings on the carriageway in order to allow the mentioned safety system to identify them on time and correctly. Road markings can be defined as a set of longitudinal and transversal lines, signs and symbols, the combination of which designs the surfaces on the traffic infrastructure. They represent a part of the whole traffic signalization and cannot be replaced by other markings or regulations. The road markings have the task of visually guiding the driver, allowing the drivers to be able to forecast the route of their safe movement. Every crossing of the full or broken line at speeds higher than 80 km/h and without an activated indicator is identified by ILAS and the driver is warned by the vibration of the driver seat. Road markings are the best aid in side, i. e. transversal locating of the vehicle and they influence directly the operation of the safety system ILAS during driving. (Author/publisher)
