PURPOSES: This study proposes a novel method based on microscopic simulation models to evaluate bicycle passing ways in mixed traffic flow conditions at signalized intersections. METHODS: Both operational efficiency and safety are taken into consideration in the evaluation. A widely used performance measure, delay, is used for evaluating the operational efficiency. Regarding the safety evaluation, surrogate safety measures (SSM) to represent traffic conflicts and the level of crash severity, DeltaS and Max.DeltaV, are applied in the proposed method. RESULTS: Extensive simulations and statistical tests show that an integrated bike-box way is identified as the best in terms of operational efficiency and safety. CONCLUSIONS: The proposed method and outcomes of this study will be valuable for bicycle traffic operations and facility design.

Purpose: Mountain biking as a sport and recreational activity has grown rapidly over the previous two decades. The purpose of this study is to analyze differences of leisure satisfaction by demographic characteristics of mountain bike participants. Research design, data, and methodology: To accomplish the purpose, the study employed purposive sample method among nonprobability sampling and collected data from 300 participants. Of collected data, 288 responses were analyzed excepted for uncompleted responses. To analyze data, study utilized statistical techniques including descriptive statistics, reliability analysis, independent-sample t-test, and one-way ANOVA, and to verify difference between individual groups in relation to significant results, Duncan's multiple range was conducted. Results: Findings indicated no differences of leisure satisfaction by gender. Similarly, education level and occupations have not influence leisure satisfaction. Yet, differences of leisure satisfaction by participation frequencies were observed. Of participation frequencies, participants riding 5 times a week were more satisfied with MTB participation than the other groups participating less 3 times a week. Conclusions: The findings provide a couple of insights in terms of promoting MTB participation. In specific, results indicated that MTB would be attractive sports that is able to appeal huge populations regardless of their education and occupation. Furthermore, consistent participation is judged an effective way to increase psychological, educational, and social satisfaction. In this sense, regional MTB clubs could play a salient role in motivating riders to more participate in MTB. Hence, establishing strategies for encouraging club activities are needed.

This research aimed at measuring Park and Green Satisfaction (PGS) using subjective indicators of 'surface, line and spot' green evaluated by citizens. Also frequency of visits to park and green measured using objective indicators (number of visits) to find the relationship with PGS. A conceptual model of PGS was developed to relate evaluation to satisfaction and finally to utilization of open spaces. A sample of 500 questionnaire survey was employed for Uijeongbu City in Korea. A Structual Equation Modeling (AMOS) techniques was used to test the hypothesized relationship among factors (construct). As a result, first, PGS was explained by three latent factors of 'urban park' (${\gamma}=0.54$), 'linear facilities' (${\gamma}=0.25$), and 'surface green' (${\gamma}=0.15$) respectively. These three exogenous construct was found very useful classification system for open spaces of cities. Second, PGS (${\gamma}=0.34$) was found as a mediating variable to utilization of open spaces and also PGS was closely related to citizens Environmental Quality Satisfaction (EQS), such concept as, 'livability' and 'aesthetic quality'. The more satisfied with park and green the more people use the space. The PGS was an important QOL indicator together with the subjective indicator of 'livability'. Third, jogging and walking trails and bike ways along the river corridor was the most important green facilities contribute to the PGS and EQS. The near the distance (within 500m) the more number of visit to river corridor (green way). The river corridor promote accessibility to nature and other parks.
