This study analyzes the probability of mode change of existing private vehicle users due to the implementation of area-based congestion pricing, then evaluates the road network performance resulted in the vicinity. A small-scale stated preference survey is conducted to car and motorcycle users who have destination within the hypothetical congestion pricing area to demonstrate mode changing by gathering their preferences on defined six mode changing alternatives. Utility functions for car and motorcycle users are developed with cost and time variables to derive the probability of each mode choice with multinominal logit approach. A proposed traffic assignment analysis by incorporating congestion pricing tariff in the link performance function is used to capture the impact of mode choice and detouring traffic caused by congestion pricing imposed. Traffic network simulation shows that implementation of congestion pricing improves road performance within the area, however, it creates route diversion for through traffic to avoid pricing area and tends to worsen off road performance in the vicinity. Out of five congestion pricing tariff combinations simulated, it is found that tariff combination of 30,000 (IDR) for car and 20,000 (IDR) for motorcycle maximizes the road network performance best.
