Modeling the Volume of On-Street Parking at Beach Tourism Objects in Bali Indonesia Based on the Available Parking Slots Units

Parking retribution fees of on-street parking is one of the local authority’s revenues (Bahasa Indonesia: Pendapatan Asli Daerah, PAD) of city or district governments in Indonesia. Currently, the calculation of parking revenue is still based on the number of parked vehicles, where the model for predicting the number of parked vehicles has not been developed much, especially for on-street parking. Currently, on-street parking research is still limited to how much parking space is needed and how parking spaces perform. This also applies to on-street parking in beach tourist destinations in Bali, which are famous for their tourism. This study attempts to develop initial model to predict the number of vehicles parked in beach tourist areas in Bali using a linear regression equation with the independent variable (X1) of the number of available parking slot unit (Bahasa Indonesia: Satuan Ruang Parking (SRP)). The results of the model consist of four models including motorcycle volume for both during weekday and weekend as well as car for both during weekend and weekend. The model of motorcycle volume during weekday is Y = 19X1-931 (R₂ = 0.97) and Y = 14.46X1-690.09 (R₂ = 0.716) for weekend. Additionally, the model of passenger car volume during weekday is 3.14X1 + 6.71 (R₂ = 0.22) and Y = 4.54X1 + 7.931 (R₂ = 0.242) for weekend.
