PURPOSES : This study presents an application plan for parking spaces for shared e-scooters using the clearance widths of sidewalks. The detailed purposes are as follows: firstly, to present appropriate spaces for installing parking lots for shared E-scooters. Secondly, to derive the specifications of parking unit spaces for shared E-scooters. Thirdly, to derive the formula for calculating the parking angle of shared E-scooters. Lastly, to provide examples of calculating the parking angle using the derived formula. METHODS : Based on the literature review, appropriate locations for installing parking spaces for shared E-scooters on sidewalks were proposed. We also investigated design factors based on a literature review to derive the specifications of parking unit spaces for shared E-scooters, and utilized the geometric characteristics of clearance widths of sidewalks to derive a formula for calculating the parking angle. Finally, we provide examples of calculating the parking angle for shared E-scooters using the derived formula. RESULTS : The results of this study are as follows. We proposed clearance widths of sidewalks as appropriate spaces for installing parking spaces for shared E-scooters. Next, we derived the specifications of parking unit spaces for shared E-scooters considering anthropometric measurements, specifications of shared E-scooters, and clearance dimensions. Moreover, we derived a formula for calculating the parking angle of shared E-scooters considering clearance widths of sidewalks. Finally, we presented examples of calculating the parking angle for shared E-scooter parking unit spaces based on clearance widths of sidewalks. CONCLUSIONS : It was concluded that the application for parking spaces for shared e-scooters using the clearance widths of sidewalks was presented. We derived the standard and compact specifications of parking unit spaces for shared E-scooters, and provided foundational data for estimating the parking capacity using a formula for calculating the parking angle of shared E-scooters. Future research directions include presenting case studies of estimating parking capacity using the parking angle of shared E-scooters.
