Truck platooning technology, which utilizes vehicle-to-vehicle communication to enable two or more autonomous trucks to travel in a platoon, is garnering attention. However, before platooning is implemented, an environment that can stably maintain a constant speed must be established. Therefore, maintaining a constant speed is a key prerequisite for truck platooning. To overcome the limitations of previous studies, which relied on traffic simulations or limited experiments, this study analyzes second-by-second truck DTG driving records obtained from highways near major domestic ports. Based on these data, a sliding-window technique was employed to detect constant-speed driving patterns and estimate the rate of constant-speed driving by section. The analysis revealed a high rate of constant-speed driving at the Noeun JCT–Dongcheongju IC, where the traffic volume was low and the road alignment was gentle. However, a low rate was observed at the Gunpo IC–Donggunpo IC, where ramp entries and exits were frequent. Subsequently, a multivariate fractional polynomial model was employed to analyze factors influencing constant-speed driving. The main factors identified were speed dispersion, average duration of constantspeed driving, and volume of large trucks per lane. This shows that speed stability, continuity of driving patterns, and vehicle composition within a section are more important factors in determining constant-speed driving than the average driving speed or traffic volume. This study is significant because it empirically elucidates the characteristics and factors influencing constant-speed driving using large-scale field data. Furthermore, it is expected to provide fundamental data for selecting suitable sections for truck platooning and establishing logistics efficiency policies.
