Central Java Province has experienced increased movement due to economic, social, and cultural developments. This increased activity has caused transportation problems, highlighting the need for effective transportation planning. A commonly used method for transportation planning is the four-step technique. Therefore, this study aimed to estimate the origin-destination (O-D) matrix for Central Java Province in 2022 and 2040. The traffic count method was utilized for calculating the O-D matrix in 2022, while the gravity method was employed for 2040. The results showed that the total movement for 2022 was 50,295 PCU/hour, while the projected amount for 2040 was 139,674 PCU/hour. In 2022, the action was primarily dominated by internal-internal trips, which account for 75% or 37,528 PCU/hour. In conclusion, the proposed approach has good validity, as indicated by a coefficient of determination (R 2 ) of 0.677.
