일반국도에서 차량 바퀴궤적의 횡방향 이동 특성 분석 = Characteristic of Vehicle Lateral Displacements on National Highways

다국어 초록 (Multilingual Abstract)

Wandering, variation of wheel tracks, has not been considered as an important factor for pavement designs and maintenance
due to measuring difficulties. In order to investigate vehicle lateral displacements on roadways, this study measured wheel tracks
on two-lane and four-lane National highways with lane widths 3.25m and 3.5m. The results showed that the tracks of left and
right wheels were distributed into different forms, and those of left wheels were more concentrated. In the mean of the left
distributions, 59.5cm and 80.7cm were obtained on lane widths 3.25m and 3.5m respectively by cars, and 58.4cm and 73.6cm
were obtained by trucks. These mean differences seem to be generated from those between the lane widths. It is recommended
to apply the distribution of left wheel tracks for pavement designs.
