  • Currently, level of service(LOS) analysis methods for pedestrian sidewalks are provided in Korean Highway Capacity Manual(KHCM, 2013). However, conventional methods provided in the KHCM produce most of pedestrian sidewalks' LOS as level A, indicating that existing analysis methods are unable to reflect realistic pedestrian sidewalks' LOS. The objectives of this research are to identify the suitability of current LOS criteria and to propose improved LOS evaluation criteria and methods with pedestrian volume data carried out for 10,000 sites in 2009. This research proposes new criteria by using the qualitative definition of LOS proposed by Fruin and Hall, new standard Korean human scale and new criteria of pedestrian occupancy space. Application results of new criteria show that more realistic results can be achieved than the existing methods. It is expected that applying the newly developed criteria and methods can make planning, design and construction of pedestrian sidewalks more realistic and various.

  • Recently, there has been a growing interest in expanded sidewalks for existing bridges. The cantilever beam system applied to expanded sidewalks for existing bridges are connected with the concrete structure by adhesive anchor bolts. However, the extended sidewalks are currently constructed without standardized regulations, which lead to excessive design of the beam spacing and installation and the construction difficulties due to the excessive over-weight. Moreover, there is only limited analysis and experiment data on the post-installed adhesive anchor bolts, so the excessive number of bolts is used for the connection. This paper deals with a method to increase the effectiveness of beam sections and anchor bolts geometry for expanded sidewalk of existing bridge. The study results showed that the failure of cantilever beam connected by adhesive anchor bolts was dominated by bond failure of interface between concrete and bolt. Also, the results indicated the possibilities of improving serviceability as well as safety of the sidewalks by changing of beam section and prestressing the bolts.

  • In recently, a growing concern for the health of urban residents increased interests in a variety of outdoor activities simply be done in terms of cost and time. They are specially interested in low-impact and safe exercises around residential or working area. Walking is the one of easily doing exercise in daytime or nighttime near residential area. The sidewalks of boulevard near the residential area is the best place for exercise because of easy access and the green space with roadside trees. However, if the nighttime is not guaranteed the proper lighting condition, the possibility of exposure to crime and the threat to pedestrian safety can be increased. Because roadside trees are one of the potential obstacle for lighting condition, supplementary lightings are important to mitigate interruption for safety. To meet such a need, the purpose of this study is to propose a simulation approach which improves lighting condition on sidewalks of boulevard with variety of roadside trees. To do so, the simulation approach is applied for analyzing the interrupted condition by classified five standard types of roadside trees considering the growth of them and finding optimal layout of supplementary luminaires by lighting types. The results of this approach shows that it is useful for assessing the safety of pedestrian in nighttime.

  • Pedestrians and vehicle users should be treated with equal importance in urban street design. However, current street design suggests that the design criteria for sidewalks is based on the functional hierarchy of the vehicles, therefore it is necessary to develop sidewalk design standards that give more weight to pedestrians rather than vehicles. For this, this study suggests that the level of service of pedestrians should be considered in the process of designing sidewalks. Currently, level of service (LOS) criteria for pedestrians in the Korean Highway Capacity Manual are based on pedestrian volume, but the volume of pedestrians is seldomly estimated in practice. So, the current LOS criteria has limitations in terms of practical use. Also, the study assumes that the pedestrian flow rate is hardly the dominant factor that could affect the LOS of pedestrians at most urban sidewalks. In this context, the study considers a new LOS for sidewalk design based on the comfort of pedestrians while passing pedestrians coming from the opposite direction. Then the study attempts to link the new LOS criteria to the land use patterns using data of pedestrian traffic characteristics acquired from the field. In addition to this, the scope in which the suggested criteria can be applied is suggested.

  • Accidents involving deaths of children and pedestrians continue to occur in child protection zones, also known as school zones. Over the three years from 2019 to 2021, 11 child deaths occurred in school zones in Korea. In December 2022, a fatal accident occurred among an elementary school student in a school zone near an elementary school in Gangnam-gu, Seoul. In April 2023, an accident occurred in which an elementary school student died in a school zone near Seo-gu Middle School in Daejeon and an elementary school in Yeongdo-gu, Busan. Until recently, child deaths continued to occur on sidewalks in child protection zones. It is time to closely review the status of safety facilities installed in school zones and related regulations. We investigated and analyzed the current status of safety facilities and related regulations installed on sidewalks in child protection zones in Korea, and identified matters necessary for institutional improvement regarding safety facilities for sidewalks in child protection zones.

  • The objective of this study was to investigate the perception of walking environment and use of neighborhood facilities of rural female elderly, who are the most susceptible to ambulatory problems. The study showed that parks, senior centers and hospitals were among the most frequently used neighborhood facilities by rural female elderly, while bus stations and senior centers were recognized as the closest facilities. Frequency of use was higher for paid sports facilities rather than parks. Hospitals and health centers were facilities that were desired to be in close proximity. Social support, self-efficacy, and attitude were the factors that affected walking environment. Street trees, accessibility to parks, and street lights were factors that showed a positive relationship with total time of walking activity while perceived crime rate and slopes were perceived as environmental challenges for groups that walked under 150 minutes per week. One factor that negatively affected walking was the lack of sidewalks on streets. Providing parks and walking trails within neighborhood, pleasant walking environments, and safe sidewalks would contribute to improved perception of neighborhood and walking of older rural women.

  • This paper analyzed and compared the service level and satisfaction of the sidewalks in collector roads from 6 different location, which has a lot of volume of pedestrians. For the study, it performed an investigation of road geometry, flow, research about satisfaction of walking and video recording. Based on this data, this study computed the service level of the sidewalks and pedestrian satisfaction. This study made a sense of correlation between service level and satisfaction. Also it focused on factors influencing on the effectiveness of satisfaction. This study also analyzed the change of walking behavior chracteristics according to the change of the level of satisfaction. This study adopted Multi-Modal Level of Service(MMLOS) method, because it could consider more factors. This study reached the conclusion that MMLOS method cannot completely reflect the level of pedestrian satisfaction. We have to consider more factors than in the current system for use in the development of sidewalk design. The result of this study is expected to reflect the pedestrian satisfaction in future sidewalks design.

  • The purpose of this study is to investigate the actual conditions of the mobility convenience facilities for pedestrians and their perception of the facilities, and thereby provide fundamental material necessary to establish a strategy of improving mobility convenience facilities. This study tried to analyze the characteristics of the mobility convenience facilities for pedestrians. Based on previous studies and "Report of Mobility Facilities of the Mobility Handicapped", this study first chose the evaluation items related to mobility convenience facilities, and then conducted a questionnaire survey and Importance-Performance Analysis (IPA). According to the study results, first, the item that needs intensive improvement was sidewalks, and the detailed indicators for sidewalks were walking safety, convenient facilities for the disabled, and pavement in order. Secondly, the items that need to be maintained were bus and crossroad. Thirdly, the low-ranking items were under-passageway and pedestrian overpass. And lastly, the items that need to be controlled were facilities for passenger terminals and bus terminals. Based on the comprehensive IPA result, this researcher judged the actual use conditions of the mobility convenience facilities in Buyeo-gun, Chungcheongnamdo. Therefore, it was found that it would be urgent to improve the direct walking environment on sidewalks. In this aspect, for future policy decision and facility maintenance, it is desirable to put the item in priority in terms of investment and come up with an improvement strategy.

  • The purpose of this study was to analyze the perception factors of a pedestrian environment that affect pedestrian environment satisfaction(PES) and determine the relationship between PES and the expected effects of health promotion. The targeted areas of study are neighborhood parks in Suseong-gu, Daegu city. First, regarding the results for the evaluation of pedestrian environment perception, 'Gentle slope' was rated the highest, while factors regarding pedestrian safety such as 'Lots of unpleasant elements', 'Risk from biking and motorcycling' and 'Many obstacles on sidewalks' were rated low. A stepwise regression analysis showed that factors such as 'Fresh air', 'Beautiful scenery', 'Continuity of the sidewalks', 'Various attractions', 'The shade of trees' and 'Lots of unpleasant elements' influenced the PES. Therefore, creating fresh air and shade trees by planting trees and removing unpleasant elements from pedestrian areas are important. Also, it is necessary to cultivate beautiful scenery and attractions through street improvement and improve the continuity of the sidewalks. Finally, in terms of path analysis, PES influenced the frequency of park use, the expected effects of physical and mental health promotion both directly and indirectly.
