Air Pollution Reduction by Optimizing Locations of Mobility Parking Hub

Environmental pollution and energy waste are intensifying due to the increase in traffic for various purposes in urban centers. While the idea of the 15-min city is about convenient travel within a region, it also needs to cover travel between regions. Accordingly, the purpose of this study is to allow parking and transfer of cars with public transportation and various shared mobility options through mobility parking hub. This is called a Parking and Ride (P&R) system, which can effectively help passenger car drivers to better fulfil the goal of the 15-min city: eco-friendly, efficient intercity travel. First, select a suitable location for your mobility parking hub by considering the location of existing car park buildings, distance to the metro, and distance to your target lifestyle station. Scenarios were set up based on the expected capacity of the selected mobility parking hub and the size of the existing parking lot. Then, for each scenario, the reduction in vehicle kilometers traveled (VKT) is analyzed. As a result, it was found that a total of 1,105.64 t/y of air pollutants could be reduced when used (100 %) by the amount corresponding to the total parking space of the mobility parking hub. The study concluded that building mobility parking hubs can reduce VKT when moving between areas. The results of the analysis show that properly placed mobility parking hubs can reduce VKTs, leading to lower air pollution emissions. In the future, living zones such as 15-minute cities will be formed, which can be used for eco-friendly movement between living zones. In addition, it can be used as a reference when designing a mobility parking hub for inter-living zone movement.
