  • Although walking is an important transport mode which should be promoted, realistic studies about walking is not sufficient. Especially, due to the transportation planning oriented toward automobile, there is not realistic analysis method for walking in the Highway Capacity Manual. Therefore, in this study the fuzzy approximate reasoning was employed to build a model for the analysis of walkways service level. For the input variable the noise level and brightness as well as the pedestrian flow rate were employed and the output variable was the walking satisfaction degree. The fuzzy models were constructed for daytime and nighttime separately. The forecastability analysis for the models were conducted using $R^2$, MAE and MSE. The values of them for the daytime model are 0.802, 0.729 and 0.735 respectively and the values for nighttime are 0.893, 0.878 and 0.860 respectively, so it can be said that the models explain the real situation well. As a result of this study, it can be concluded that the noise level has stronger effects to walking satisfaction then the brightness in night.

  • In the middle of motorization, the traffic problems become serious social problems in Korea. The walking environment is not only a topic which restores the community spirit of a city or society but also a lever which renovates the future space of the city environment-friendly. Thus, the Purpose of this study is to suggest the new criteria of walkway level of service adopting the concepts of safety. convenience, comfort, environment, security, and continuity in addition to present pedestrian flow rate, and to provide basic data for walkway plan in Korea. In order to analyze the adequacy of the present walkway level of service criteria, the walkways of which service levels were A, C, E according to USHCM were selected as study walkways, and an interview surrey was conducted to compare the three service levels with those that pedestrians evaluate actually. Also, another interview survey was conducted to analyze the service conditions and satisfaction level at the walkways of high service levels(A and B). For the establishment of more reasonable walkway level of service criteria. the survey of pedestrian\`s consciousness for walkway service was conducted. Based on the survey results, the new criteria for the evaluation of walkway service were selected and the six levels of service for each criterion was analyzed: so the comprehensive criteria of walkway level of service were suggested.

  • 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.
