HUMAN FACTORS RESEARCH TO DEVELOP LINE MARKING STANDARDS

Periodic renewal of linemarkings is required to ensure that an adequate level of brightness is maintained. This study outlines a market research approach to determine what this minimum level should be, based on the views of a representative cross section of Victorian drivers. Subjects were required to drive a test route linking 12 sites, covering a representative range of linemarking conditions. They were asked to rate the adequacy of the linemarking at each site from very poor to very good and to judge whether they considered the level acceptable or not. Linemarking standards were established for night time performance based on measurements of retroreflectivity (the amount of light from headlights reflected by the line) and for daytime performance using luminance factor (a measure of the ambient light reflected by the line). Additional modelling showed that, for lines to appear as bright to truck drivers as they do to car drivers, they would have to be approximately 1.5 times as bright. These results must be considered in light of the current state of line marking on Australian roads and the costs of conforming current levels of brightness to a minimum standard before a single standard can be defined.
