  • PURPOSES : The purpose of this study is to identify the factors affecting the effectiveness of speed limit change that is defined as the amount of increased travel speed. METHODS : A ordered logit model was adopted to analyze the relationship between the change in travel speed and contributing factors. A stretch of Kyungbu freeway was selected for the analysis because the Korea expressway corporation has raised speed limit from 100km/h to 110km/h since September 1st in 2010. RESULTS : The results showed that geometric design elements, speeding cameras, and section length were identified as factors contributing the effectiveness. Contributing geometric design elements include the number of horizontal curves and vertical curves that do not meet the design requirement with 110km/h speed limit. CONCLUSIONS : The outcome of this study will be used for establishing various traffic operations and control strategies for freeway speed management.

  • This paper was to use choice experiments in the analysis of consumer choice behavior and preferences for five different attributes(the origin of rice, a quality certificate, a quality control, a traceability system, the price of rice) in Cheongju City. Completed surveys yielded 712 responses which were analyzed using the conditional logit model to analyze the marginal willingness to pay of the four attributes(the origin of rice, a quality certificate, a quality control and a traceability system) per household and estimated the marginal willingness to pay of the set of feasible options. The result of this study can be used as a guide for the rice industry in the design of possible labeling schemes.

  • As an empirical study on Daegu Downtown showing decentralization phenomenon, the purpose of this study is, based on the residential satisfaction research targeting the Downtown residents, to analyze the residential environment satisfaction and residential preference. Considering the parameters of measurement, we used the Ordered Logit Model and Logistic Regression. The results are as follows: First, the comprehensive residential environment satisfaction is relatively lower than that in 2008 and the residential preference in Downtown is similar to that of the past. Second, among the 7 factors that constitute the Downtown residential environment, the house, the landscape, and the security have a relatively large influence on the comprehensive residential environment satisfaction. Third, the residential environment factors which affect those who are hoping continuous Downtown residence are the safety, the house and the complex.

  • The objective of this study is to analyze factors affecting purchase intention and conduct price sensitivity analysis of Korean Shine-muscat for Chinese consumers. Logit model has been set up to find purchase intention with survey data which was conducted in Beijing China. The results show that the high-income, unmarried consumers are more sensitive to the price of Korean Shine-muscat than low-income, married consumers, but have higher purchase intention. Also, consumers who perceive Korea positively and those who prefer Korean dramas are more sensitive to the price but have higher purchase intention. Consumers with a high monthly purchase frequency of Shine-muscat have higher purchase intention of Korean Shine-muscat, but are more sensitive to the price. The results of this study can be utilized as basic information for promoting the export of Korean Shine- muscat to China.

  • The Purpose of this paper is to estimates consumers' willingness to pay for Urban Agriculture Park attributes. we analysis the marginal WTP by choice experiment method. Choice experiment (CE) is designed to elicit the marginal WTP differences among urban agriculture park attributes (garden scales, learning and experience area, leisure and relaxation area and fund). The results of multinomial logit model are meaningful, the total marginal WTP on the urban agriculture park attributes is 18,852 won. gardens scales is 2,949 won, learning and experience area is 11,284 won, leisure and relaxation area is 4,619 won. In the current laws, the facilities related to urban agriculture park is not. Taking advantage of the new urban agriculture park, Amendments of the law is required.

  • In this paper we used the KLIPS(Korean Labor and Income Panel tudy) data that surveyed from 2006(wave 9) to 2009(wave 12). Other previous studies are concerned with the panel attrition in the early wave, but this study classifies the response pattern and investigates some factors that influence panel attrition when the panel tends to stabilize. It was revealed that panel attrition was influenced by relocation and housing type through the logit model. Besides it was appeared that panel attrition was affected by the monthly living expenses and the overall household income through the decision tree.

  • This paper examines the impact of reliability on consumers' demand for environmentally friendly agricultural products using ordered logit model. We survey 100 housewives living in the capital region and five metropolitian cities cross sectional data in 2007. This paper especially estimates the impact of instrumental factor, such as history tracking system, provision of information, safety assurance and labelling of brands on the consumers' demand. The main results show that provision of information and safety assurance affect consumers' demand more confident than others. In order to motivate consumers to buy more environmentally friendly agricultural products, the safety should be assured and more information on production and marketing channel should be labelled.

  • The purpose of this study is to analyze the effects of useof weather and climate information on farmer income. To accomplish the objective of the study a farm survey was conducted, whose target respondents were local correspondents and reporters of the Korea Rural Economic Institute. The ordered logit model was employed for empirical analysis on determining whether use of weather and climate information affects farmer income. The analysis results show that the greater is farmer use of short-range weather forecasts, the higher is the income. The results also show higher farmers income with use of short-range special weather forecasts. Based upon the empirical results, the dissemination of more precise weather and climate information is suggested to increase farmer income.

  • In recent years, the planning of livable communities has emerged as a new paradigm. The concept of livable communities is related to both the spatial balance of working, playing, and living and the promotion of green modes of transportation, such as walking and biking. This study uses a disaggregate travel survey conducted by the Seoul Metropolitan Area in 2006. I applied a multi-level random intercept logit model to estimate the effects of land-use characteristics on the choice of green modes, holding a traveler's socio-demographic characteristics constant. The empirical results show that higher density and more mixed land-use development encourages people to walk and bike even when individuals have the same socio-economic characteristics. This paper demonstrates that land-use planning by itself can play a role in the creation of livable cities and the decline of greenhouse gas production.
