. Toll is charged due to saving invehicle operating costs and time, comfort and better facilities, hence the amount of toll rates must satisfy the principle of profit or benefit to users. The increasing numbers of road users and economy growth lead to congestion at toll road sections, especially during peak hours. Thereforetoll rates variation associated with using time to provide incentives and disincentives in order to distribute toll road's use to prevent congestion occur at a specific time should be taken into consideration. This study was conducted to determine the effect of toll ratesvariationupon its application and its elasticity. Jakarta Intra Urban Toll (JIUT) and the Jakarta Outer Ring Road (JORR) were used as models. A Stated Preferencesurvey, and some simulation of traffic flow and toll roads operator's income and road networks using SATURN software were undertaken. This study showed that the increase in toll rates during peak hours would reduce the volume of highway traffic. However, the effect of increasing toll rates did not significantly change the value of Volume to Capacity Ratio (VCR), hence the Level of Service (LOS),due to time value, high transportation needs and limited road capacity.
