The development of information and communication technology has changed transportation services to be more dynamic, such as the emergence of Grab online transportation. The use of the Grab application every day allows the collection of large-scale GPS trajectory data (big data). This study aims to identify spatial clusters of online transportation pick-up points at certain times in East Jakarta City and visualize the trajectory of online transportation movements to see differences in community mobility patterns in East Jakarta City at various times. Data were analyzed using the Density-Based Spatialclustering of Application with Noise (DBSCAN) method with optimized epsilon and minimum sample values through Bayesian to determine clusters, as well as the Kernel Density Estimation (KDE) method to calculate hourly trajectory density using adjusted bandwidth values. The results of the density calculation were visualized using the Kepler.gl platform.
The results of the study showed 65 clusters of ride-hailing pick-up points formed on weekdays and 35 clusters on holidays. Weekdays show more clusters and are concentrated around educational institutions, office areas, and supporting facilities, reflecting routine mobility, while holidays show fewer clusters and are spread across several areas including recreational areas and shopping centers. The density of ride-hailing trajectories also shows differences in density patterns between weekdays and holidays. Weekdays have high density in some areas with routine routes, while holidays show a more even distribution of density due to more flexible travel activities.
