PURPOSES : This study explores the preference of shared autonomous vehicle service in an underground dedicated environment. METHODS : A stated preference survey was conducted to examine the mode choice behaviors on autonomous vehicle service competing with existing modes. Multinomial logit was employed to estimate the parameters of explanatory variables from the surveyed data. The model was estimated with alternative specific parameters rather than generic parameters. The value of time was also estimated using the parameters of the mode choice model. RESULTS : The results showed that the travel cost had the highest sensitivity to public transportation and the lowest to private cars. We also found that the value of the in-vehicle travel time was highest for private cars, lowest for public transportation, and intermediate for SAVs, suggesting that SAVs could serve as a premium public transport option. Additionally, the out-vehicle time coefficient was higher for public transportation compared to that for SAVs, indicating that users are more willing to tolerate longer out-vehicle times for SAVs due to their high-speed service compared to that of public transportation. CONCLUSIONS : This study presents a direction for policy regarding the adoption of shared autonomous vehicle services by considering the attributes that are valued by users of each mode.

PURPOSES : This study is to analyze factors affecting improper parking behaviors in a perspective of personal mobility users. Detailed purposes are as follows. Firstly, exogenous and endogenous latent variables were set. Secondly, structural equation model were constructed. Hypothesis for the structural equation model were established. Then model’s goodness of fit was analyzed and following the result model was modified. Lastly, factors affecting improper personal mobility parking behavior was found out. METHODS : Based on the literature review, exogenous and endogenous latent variables were set. Correlation between latent variables and their observed variables was defined to build structural equation model. According to the model hypothesis was established. In order to collect data, survey was conducted on personal mobility users. Model’s goodness fit was verified and the model was modified. Lastly in order to find out the factors affecting improper personal mobility parking behavior path analysis was conducted. RESULTS : Based on literature review, based on 6 of latent variables the structural equation model was made. Survey was conducted on 341 participants who has used personal mobility at least once based on Likert 5-point scale. Out of 341 responses 22 responses considered as careless responses were removed. As a result of analysis of structural equation model, it turned out that ‘ease of transfer’ had a positive effect on improper parking of personal mobility meanwhile ‘convenience’ and ‘road condition’ had a negative effect. CONCLUSIONS : It was concluded that the proximity and accessibility to the transfer facility could be important when installing personal mobility parking lot as improper parking behavior of personal mobility users could be affected by ease of transfer to other traffic mode. Also, interval of parking lots, location and its road condition should be considered in order to make it convenient for users to find parking lot and to encourage them to use it more often.

PURPOSES : The purpose of this study is to identify the beneficiaries of car-sharing that can utilize autonomous car-sharing services when they are introduced. METHODS : This study was conducted in two stages. The first step was to analyze the characteristics of shared car usage by region and rental time using t-Ttest. The second step was to analyze the beneficiaries of autonomous car-sharing services if they are introduced. The beneficiaries were derived using parking time and survey data. RESULTS : Car-sharing behavior showed statistically different usage characteristics by region and rental period. However, the distance traveled per trip for short trips was similar. When the autonomous car sharing service with free return and rental is introduced, 31% (Jeju) to 38% (Daejeon) of short-term renters and 50 to 52% of long-term renters are expected to benefit. CONCLUSIONS : When introducing autonomous car-sharing services, it is necessary to establish a shared car strategy that reflects the characteristics of car-sharing use by region and rental period. In particular, in Jeju Island, where the rental time is relatively longer than Daejeon, the introduction of autonomous car-sharing services will contribute to reducing the cost of shared vehicles in terms of cost.

PURPOSES : This study is to analyze preference of shared personal mobility(shared e-scooter or shared bike) parking lot. The detailed purposes are as follows. Firstly, the attributes and attribute levels of shared personal mobility are developed. Based on combined attributes and attribute levels several profiles were composed. Preference data of shared personal mobility parking lot is collected through survey. Preference of shared personal mobility parking lot was analyzed using conjoint analysis. METHODS : Based on the literature review, the attributes and attribute levels that might affect behavior or intention of shared personal mobility parking were developed. Several profiles that contain combined attributes and attribute levels were created in a fractional factorial design. In order to collect preference data of shared personal mobility parking lot, online survey were proceeded. The survey participants were asked to mark preference point between point 1 and point 10. Lastly, preference of shared personal mobility parking lot was analyzed using conjoint analysis. RESULTS : Based on literature review, 5 attributes for conjoint analysis were set.(Distance between shared personal mobility parking lot and destination, Space for shared personal mobility parking lot, Location of shared personal mobility parking lot, Type of shared personal mobility parking lot, Interval of shared personal mobility parking lot). With the combination of 5 attributes and their levels, 16 random profiles were made. Online survey was proceeded with 300 participants who have used shared personal mobility. Using conjoint analysis utility and importance of each attribute has been calculated. As a result, the preference got higher when distance between parking lot and destination and intervals of parking lots are short. In addition racks are tended to be preferred and it seems to be more profer to install parking lot on buffer zone of pedestrian road instead of adjacent to private building. CONCLUSIONS : It could be important to install personal mobility parking lot considering preference of parking lot attributes in order to encourage users to use the proper parking lot instead of parking anywhere.

Industrial complexes are areas where manufacturing companies are integrated, and logistics between tenant companies play a very important role, but idle resources can occur depending on the situation if each company operates independently. Accordingly, this study aimed to reduce overall logistics costs and increase corporate productivity by looking at ways to share and utilize logistics resources such as warehouses and transportation equipment to efficiently utilize logistics resources in industrial complexes and implementing a logistics sharing platform that can share these idle resources. To this end, this study conducted a research survey on the logistics status of manufacturing companies in Ulsan-Mipo Industrial Complex, based on this analysis, the necessity of logistics resource types and utilization of industrial complex resident companies, and based on this, a service model for logistics resource sharing was studied. In addition, it was intended to analyze the operational characteristics of the existing logistics system to derive improvements and to derive optimal measures to utilize information on shared idle resources. This study confirmed the importance of sharing and utilizing idle resources to optimize logistics resources in industrial complexes, and is expected to contribute to reducing logistics costs and increasing logistics efficiency of tenant companies.

Big data technology is being used in various fields followed by the development of information and communication technology.

PURPOSES : This study aims to suggest how to utilize "standby data" of shared mobility that does not contain personal information and examine whether "standby data" can derive existing shared mobility operation analysis items similarly. METHODS : An existing Personal Mobility (PM) traffic pattern analysis was performed by identifying the user (User ID) and the user's route in a time frame. In this study, the PM traffic pattern analysis focuses on a vehicle (ID of the standby vehicle) and its standby location. We examined whether the items derived from the User ID-based traffic pattern analysis could also be derived from the standby Vehicle ID-based analysis. RESULTS : The analysis showed that all five items (traffic volume by time slot, peak time, average travel time, average travel distance, and average travel speed) of the existing User ID-based PM travel analysis result could be derived similarly using the standby Vehicle ID-based PM traffic analysis. However, the disadvantage is that the average driving distance is calculated as a straight-line distance. It seems possible to overcome this limitation by correcting the average driving distance through linkage analysis with road network data. However, it is not possible to derive the instantaneous maximum speed or acceleration/deceleration. CONCLUSIONS : In an era in which various means of transportation are being introduced, data sharing is not preferred because of legal issues.Consequently, it is difficult to understand the use of new means of transportation and formulate new policies. To address this, data sharing can be active based on standby data that is not related to personal information.
