This study employed travel cost method together with other expenditure to identify the value
of park benefit to users. Since the benefit accumulated from total expenses and time spend for
both traveling and perform activity at park. This study integrate the traditional method on
travel cost valuation together with other expenses to reflect total benefit generate at site
visitation. However, it is necessary to assume that users select one site rather than multiple
sites to visit on any one trip. By this assumption, it can allow us to determine value of both
incur travel costs for the actual trip to park and the actual cost incur on actual activity carry
out at park.
The assumption includes the value of on-site time that has similar concept to the well known
value of time. The valuation of recreation benefit based on travel for public park case is
determined by using the following equation.
