This study proposes an integrated simulation approach, which consists of a microscopic traffic simulation model, a vehicle dynamics model, and an emission estimation model, in order to estimate emissions based on more reliable vehicle performance measures. The vehicle performance measures such as engine power and engine speed significantly relate to the amount of emissions, and road curvatures and inclinations are the core inputs affecting these vehicle performance measures. Therefore, providing reliable vehicle performance measures reflecting the road geometric attributes is critical for a reliable emission estimation. This study proposes to use the microscopic traffic simulation model for generating vehicle trajectories, which is advantageous in modeling various traffic situations, and the vehicle dynamics model for producing the vehicle performance measures based on the vehicle trajectories. Finally, the outputs from the vehicle dynamics model are fed into the emission estimation model to compute emission measures. This study conducted a case-study using two road sections, one is a hypothesized road section, including various curvatures and inclinations with regular variations, and the other is a Kesselberg road section, which is an actual geometry in Bayern, Germany. The emission measures are estimated in these case-study road sections using both an existing simulation approach and the proposed integrated simulation approach. The difference between these two emission estimation approaches is discussed in terms of the emission measures, including fuel consumption, nitrogen oxides, and particulate matters.  相似文献

Web-based permission marketing: Segmentation for the lodging industry   总被引:1,自引:0,他引:1  
Permission marketing is becoming an important tool in maintaining relationships with travelers via the Internet. Its growing importance can be seen in tourism marketing, specifically in the lodging industry. With an increase in industry use, the effectiveness of this technique needs assessment. This paper initiates this process by examining current methods used to collect contact information for the purpose of permission marketing. Three segments of the market are identified and compared based upon their willingness to supply contact information. Significant differences were found in socio-demographics, online habits, trip characteristics, and website design preferences. Implications for lodging marketers are presented and future research topics are discussed.  相似文献

The purpose of this study threefold: to determine whether a shared cultural model of the importance of a set of leisure activities to a good leisure life existed in urban Taiwan, the degree to which cultural consonance in leisure mediates the relationship between leisure constraints and leisure satisfaction, and the degree to which leisure satisfaction affects life satisfaction and self-rated health. Results indicate that a cultural model of the importance of leisure activities to a good leisure life existed among sample members. Second, higher levels of self-reported participation in leisure activities that are culturally agreed upon as more important for a good leisure life are more strongly associated with leisure satisfaction than are activities culturally agreed upon as less important. Finally, leisure satisfaction strongly predicts both life satisfaction and self-rated health.  相似文献

Crowded retail shopping conditions can result from many shoppers being present during a given time and at a given place, as well as from limited customer space owing to inadequate floor layout design and allocation of fixtures and merchandise on the floor. This study investigated the effects of the perception of human crowding and spatial crowding on consumer shopping behavior through mediation of emotions of pleasure, arousal, dominance, and a feeling of satisfaction in an international market. A store intercept survey was conducted on 554 hypermarket consumers in Taipei, Taiwan. The proposed structural relationships among perceived retail crowding, emotions, and retail outcomes were analyzed by using confirmatory factor analysis and structural equation modeling with Lisrel 8.54.

The results of the study demonstrated the effectiveness of the proposed model in delineating the relationships of retail crowding-emotions-satisfaction-retail outcomes under actual retail environments. The study found that while human crowding perceived during shopping at a hypermarket store positively impacted shoppers' feelings rather than negatively, spatial crowding perceived due to high spatial density negatively impacted shoppers' positive emotions. The findings supported the view that retail crowding affected various shopping activities through influencing positive emotions and summary feelings of satisfaction. Managerial implications of the study were also discussed.  相似文献

Drawing upon the theory of virtue ethics, this study builds a decision tree predictive model to explore the anticipated impact of good traits (i.e., virtuous and personality traits) on socially responsible consumption. Using R statistical software, we generate a classification tree and cross-validate the model on two independent datasets. The results indicate that the virtuous traits of self-efficacy, courage, and self-control, as well as the personality traits of openness and conscientiousness, predict socially responsible purchase and disposal behavior. Remarkably, the largest segment of socially responsible consumers in the study (41 %) scored high in self-efficacy and openness. This result suggests that marketers should focus on these good traits when creating advertisements to encourage sustainable consumption. Our study contributes to enhancing knowledge about the social and psychological aspects of the sustainability movement and provides a new analytical approach to predicting socially responsible consumption.  相似文献

This paper investigates the volatility persistence, volatility variability from day to day and transmission of volatility in seven Southeast Asian stock markets from 1980 to 1991 using the ARV approach. We found strong evidence that shocks to volatility are persistent in Taiwan. Moreover, the Stock Exchange of Thailand Daily Index has the strongest interday volatility fluctuation. Instantaneous causality of volatility among six of the seven markets (except Seoul) was discovered. Besides, there is significant volatility spillover effect from Hong Kong to Taiwan, Malaysia to Singapore and Singapore to Malaysia in the period 1980 to 1991.  相似文献

Most small and medium enterprises (SMEs) in Korea struggle in financing R&D. Thus, the Korea Core Industrial Technology Investment Association (KITIA) was established to implement a matching fund program (MFP) to help SMEs with this undertaking. Applicant firms to the MFP are reviewed first based on their technology levels and are required to attract financing from venture capitalists (VCs), before receiving funds from the MFP. This paper, based on KITIAs MFP applicant data from 2001 to 2004, evaluates the performance of the MFP in terms of the success rate of funded SMEs’ initial public offerings (IPOs) and bankruptcy rates in relation to those SMEs that could not attract matching funds. Propensity score matching was used to eliminate selection bias from the data in order to assess the actual treatment effect of the MFP. According to the result of logistic regression applied to the matched data, MFP apparently did not have significant effects on IPO success and bankruptcy. This implies that MFP needs to allow VCs more time to evaluate SMEs covering qualitative aspects as well. It is expected that this change of structure can provide better performance of MFP in terms of IPO success and bankruptcy of matched SMEs.  相似文献

Despite the importance of market segmentation, the growth of the travel and tourism industry in Taiwan, and the repeat travel phenomenon in tourism, relatively few studies have examined the behavior of repeat travelers in the East Asia region. The present study was designed to fill this gap. This exploratory study applied multistage segmentation in the context of repeat travel behavior to Taiwan. It examined the socio-demographic profile, trip characteristics and expenditures of Taiwan inbound repeat travelers. The results indicated that nationality, income, type of travel arrangements and information search behavior significantly affected repeat travel behavior. In terms of travel expenditures, males spent significantly more than females. Those travelers between 40 and 60 years old tended to spend the most when they visited Taiwan compared to other groups. Chinese travelers were most likely to have traveled to Taiwan more than once among all nationalities compared in this study. Those from Korea and Japan spent the most money among all nationality groups. This study provided several significant implications for the marketers of tourism in Taiwan.  相似文献
