Abstract

The rapid growth of motor vehicles in urban areas significantly contributes to air pollution, particularly along high-traffic corridors such as Tegar Beriman Road, Bogor Regency. This study analyzes wind patterns and their influence on vehicular pollutant dispersion using WRPlot View 8.0, based on one-year meteorological data from BMKG. A descriptive quantitative approach was applied to process wind direction and speed data into wind rose diagrams and frequency distributions. Results show that wind direction is dominated by the northwest (NW) sector (48.22%), followed by north (20.27%) and west (15.07%). Wind speeds are mainly within 3–4 m/s (46.30%) and 4–9 m/s (31.51%), indicating that over 77% of conditions fall within moderate to strong categories. This reflects a dynamic atmospheric system with high dispersion capacity. The alignment between dominant direction and wind speed suggests that pollutant transport is concentrated along a consistent pathway. As a result, emissions are likely dispersed toward the southeast (SE) as the primary downwind area, potentially experiencing higher exposure. Although low wind speeds (21.92%) may allow localized accumulation, the absence of calm conditions indicates continuous airflow. These findings highlight the importance of wind patterns in shaping urban air pollution distribution and support the development of targeted, evidence-based air quality management strategies
