  • The walkway level of service (LOS) is conceptualized using pedestrian flow rate, speed, and density according to the Korean Highway Capacity Manual (KHCM). However, as it is based on the data of commuters at peak hours, it needs to be reevaluated considering various trip purposes and a pleasant pedestrian environment. Thus, the authors aimed to investigate and analyze the characteristics of each group: pedestrians during the peak hour and those during the non-peak hour. Then they were verified statistically for the walkway evaluation criteria. In this study, the authors investigated pedestrian speed and flow in a complex transit center walkway with diverse trip purposes by peak and non-peak hour. Then the authors statistically verified the differences between the groups. A model was built for estimating pedestrian density by speed and flow; it was used to calculate the walkway capacity (67.3p/m/m) corresponding to LOS E. The authors established new criteria for LOS, applying the LOS from the HCM. These standards can then be used as the design standards for pedestrian walkways.

  • The main purpose of this study is to discriminate the pedestrian environment by simple calculation such as using the matrix from pedestrian level of service. However, the general use of pedestrian level of service cannot discriminate the environment of footpaths, especially in Seoul. Most of the passages in Seoul are showing level A, which means most passages are spacious, but pedestrians don't agree that passages are wide enough to walk. In conclusion, comparing the pedestrian level of service with pedestrian satisfaction in different circumstances such as use of building in lower floors. Test areas are 1,157 spots in Seoul. First, The new pedestrian level of service shows equally in all spots. Second, spots where the highest pedestrian satisfaction are mostly in level B or level C, thus planning the walkways in future, level B or level C is recommended in most cases.

  • Pedestrian performance measurement has generally used the average values of pedestrian volumes and speeds from a sample, although each individual's pedestrian behavior of the sample is mainly affected by his/her socio-economic and physical characteristics. In particular, if such individual characteristics of the sample have wide variations, the average values are hard to be representative. In this respect, this study found that a platoon of pedestrians had a major effect on their pedestrian flows on sidewalks. The more platoons was mixed on pedestrian roads, the lower pedestrian flow rate was. The indexes such as a pedestrian flow rate and an occupancy space are typically calculated by pedestrian volumes in a given period of time regardless of the existence of a platoon. However, it is plausible that a pedestrian speed and a level of pedestrian congestion can be different under the equal amount of pedestrian volumes. Therefore, this study suggested criteria for determining level of service for pedestrian considering platoon effects and confirmed that two places had different pedestrian LOSs because of the platoon effects, even if they showed the same pedestrian flow rate.

  • The pedestrian traffic flow has more complicated microscopic features than vehicular traffic flow. Without any designated lanes or any guidance, pedestrians naturally move and change their routes in two dimensional domain with ease. Thus the assessment of pedestrian comfort level should be considering the microscopic features of pedestrian flow. This study is aimed at developing pedestrian comfort criteria based upon pedestrian flow simulation model. This study suggests three criteria to determine pedestrian comfort level; the deviation of route, the acceleration of walk, and the number of collision. Each criterion, which can address the unique walking patterns of pedestrian flow, is represented as each different function with respect to traffic flow rate. The criteria can be the additional indicators to determine the level of service of pedestrian flow together with traffic flow rate and walking speed.

  • In this paper, the rotated hexagonal lattice model (RHLM) was proposed, which is applied to pedestrian flow, and developed the simulation model for the pedestrian counterflow. RHLM is an upgrade version of the square lattice model(SLM) and hexagonal lattice model(HLM). The simulation was performed at the hexagonal lattice $20{\times}20$ and evaluated by different speed, density and flow conditions. Simulation results are compared with SLM and show that RHLM can replicate the characteristics of pedestrian traffic more effectively and reliably than any other existing models from several perspectives. First, RHLM can explain the shortest-path movement of pedestrians and more realistic avoidance motion. If they cannot move straight direction, they can move shorter distance from previous position to destination. Second, RHLM reflects the characteristics that the pedestrian can move with higher capacity and the speed of pedestrian flow is hard to zero.

  • This study describes an improved model for estimating pedestrian LOS (Level of Service) by utilizing the space occupied by pedestrians. The method introduced the concept of conflict along the bi-directional pedestrian flow which enables calculating conflict area and average travel time in walking. Especially, the method incorporates the idea of generalized density concept which can consider effective walking area and pedestrian flow rates that might vary during the analysis period. After establishing methodology, adjustments of pedestrian LOS criteria in term of walking space occupied by pedestrians were performed. As a result, walking-occupied space at capacity level is 0.68 and corresponding pedestrian flow rate was calculated as 80 persons/min/m, while different pedestrian-occupied spaces were ordered to classify LOS at the points where the gradient changes. Furthermore, the statistical verification of service levels has shown that there is significant difference among all LOS categories at 5% significance level.

  • Located in the middle of lanes, the station of a median exclusive bus lane generates pedestrian groups on the green light of a crosswalk and causes pedestrians delays passing the access section. For the purpose of showing these facts, the pedestrian analysis, on which the queuing theory is applied, is presented in this study. The Result is that the pedestrian environment was deteriorated (LOS D) compared to an exciting pedestrian analysis based on 15 minutes of pedestrian volume (LOS A). A pedestrian level of service has been reevaluated based on an arrival rate on the median bus station in order to examine whether the result reflects reality or not. In result, it was similar outcomes to this study.

  • Korean Highway Capacity Manual (KHCM) has been used when we analyze the pedestrian Level of Service (LOS) of a pedestrian facility. However, the pedestrian LOS by KHCM is largely insensitive to pedestrian congestion levels. The objective of this study is to identify the source of this problem within the KHCM calculation method, and to propose an improved method using the case study from Seoul. Based on KHCM results, the pedestrian LOS is A for more than 90% of the Seoul region, which seems to be unrealistic. On the other hand, this study includes an effective adjustment parameter using the absolute value of effective sidewalk width. Using this method, results shows some changes including newly identified areas of LOS C and LOS D. The analysis of pedestrian LOS is carried out for the entire metropolitan region of Seoul in order to evaluate area wide pedestrian level of service in Seoul.

  • 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.

  • This study develops composite indicators that is capable of estimating QOS (Quality of Service) of pedestrians by enhancing estimation for Level of Service in present transporting spaces for pedestrians that merely concerns quantitative indicators such as pedestrian flow rate, pedestrian stoppage. This paper conducts survey questionnaire to collect data. It utilizes AHP(Analytic Hierarchy Process) and ANP(Analytic Network Process). The main results show that: first, ANP is better analytic methods than AHP due to the fact that pedestrians feel repetition when they judge level of service. Second, qualitative factors such as pedestrian behaviors, maintenance, scenary for pedestrians and environments should be considered. Importance of qualitative factors is higher in residential area than other areas. I expect that using qualitative indicators and quantitative indicators is appropriate in order to estimate pedestrians' QOS.
