Pedestrian facilities encompass pedestrian roads, stairs, and queuing areas exclusively designed for pedestrian use. The Korean Highway Capacity Manual provides guidelines for analyzing the capacity and level of service of pedestrian facilities. However, there is a lack of analysis methods tailored specifically for pedestrian facilities. Therefore, in this study, we introduced a new standard of pedestrian space to account for changes in the Korean body ellipse. Furthermore, based on this newly defined pedestrian space, we proposed a new standard value for the level of service of queuing areas. The results of on-site surveys confirmed that the proposed level of service can effectively reflect the actual walking situation.

The objective of this study is to develop the design criteria of traffic island considering pedestrian level of service (LOS). In pursuing the above, this study gives particular emphasis to suggesting the minimum design space of traffic island in order to maintain pedestrian LOS C and D, and the critical pedestrian traffic volume that reflects the intersection geometry (2 lanes per direction) through the simulation analysis. The main results are as follows. First, the spaces of 160 traffic islands, which meet the pedestrian LOS C and D and reflects the pedestrian traffic volume by signal cycle, are drawn by using a commercial simulator VISSIM. The relevant spaces of traffic island in terms of both the pedestrian LOS and the pedestrian traffic volume are evaluated to range from $3.0m^2$ to $41m^2$. Second, the critical pedestrian traffic volume for the operation of traffic island is evaluated to be 1,000-1,300 person/hour at LOS C and 1,600-1,800 person/hour at LOS D, respectively, when a cycle of 120-150 seconds were applied to a intersection with two lanes per direction.
