8 charged tunnels and roads are being operated in Busan city, 2003 presently. However, most of these facilities have been constructed and operated by civilian capital based on civilian investment law. Civilian operators are preparing investment cost recovery operating expenses of facilities through toll price levy but the profitable toll price levy have not been ensured because backlash about toll price levy of the road users is harsh. Also, a burden about toll price is large and requested reduction of toll price by users. Therefore, at it's fact that the reasonable toll price computation which both users and operators can accept is very urgent. In this study, first a problem of toll price computation is supplemented of a white as the subject of study sheep tunnel, second reasonable toll price of the white sheep tunnel which is able to achieve a balance recovery of investment cost, profitability and benefit cost of users is computed by using an existing toll price system. First the largest toll price which is sufficient both investment capital recovery rate of a civilian operator and the rate of return and time value and utility of toll price considered the use pattern of tunnel users are acquired a toll income maximization model and charge sensitivity of a tunnel user and Sub-compact car 500 Won, small size car 900 Won, super large size car 1,100 Won were calculated. Second, it is indicated that the results of converting the total revenue into Net Present Value of the time of completion, the case on white sheep tunnel, shows that if about 1,544 billion won are collected as profit and loss turning point, returns of about 151 billion won is generated. However, it is considered that collecting the charge by 2020 is appropriate in order to maximize social welfare and reduce a burden of users.
