이인원 대한교통학회 1983 大韓交通學會誌 Vol.1 No.1
In recent years, significant advances have been made enabling travel demand analysis and network design methods to be used as increasingly realistic evaluation tools. What has been lacking is the integration of travel demand analysis with network design models. This paper reviews some of advanced (integrated) modeling approaches and presents future research directions of integrated modeling system. To design urban transportation networks, it is argued that the travelers' free choice of mode, destination and route should be introduced into transportation network design procedure instead of assuming that trips from a zone to a workplace are fixed or deriving them in a normative procedure to achieve hypothetical system optima.

만화 그리기 중심 스토리텔링 활동이 유아의 친사회적 행동에 미치는 영향
이인원 한국열린유아교육학회 2019 열린유아교육연구 Vol.24 No.1
본 연구의 목적은 만화 그리기 중심 스토리텔링 활동이 유아의 친사회적 행동에 미치는 영향을 알아보기 위한 것이다. 연구의 대상은 D시에 소재한 H유치원에 재원 중인 만 5세 유아 43명으로 실험집단(22명)과 비교집단(21명)으로 임의 배정하였다. 실험집단에게는 만화 그리기 중심 스토리텔링 활동을 5주간 주 2회, 총 10회를 실시하였으며, 비교집단에게는 생활주제에 따른 만 5세 누리과정을 실시하였다. 만화 그리기 중심 스토리텔링 활동은 이야기 들려주기, 만화 그리기, 다시 이야기하기를 차례로 하였다. 친사회적 행동의 집단별 비교를 위하여 친사회적 행동 검사를 실시하였으며, 집단 간 차이를 알아보기 위해 ANCOVA를 실시하였다. 그 결과 만화 그리기 중심 스토리텔링 활동에 참여한 실험집단의 유아가 비교집단의 유아보다 친사회적 행동이 유의미하게 증진된 것으로 나타났다. 따라서 본 연구에서 고안한 만화 그리기 중심 스토리텔링 활동이 유아의 친사회적 행동 증진에 긍정적인 영향을 미쳤음을 알 수 있었다. 이는 유치원 교육현장에서 적합한 교수-학습방법으로 적절히 활용될 수 있음을 시사한다. The purpose of this study is to investigate the influence of cartoon-oriented storytelling activities on the pro-social behavior of young children. The subjects of the study were 43 five-year-old children attending H kindergarten in D city, randomly assigned to experimental group (22) and comparison group (21). The experimental group participated in cartoon-oriented story telling activities 10 times, twice a week for 5 weeks, whereas the comparison group participated in the Nuri curriculum based on daily life. The cartoon-oriented storytelling activities consisted in order of storytelling, drawing cartoons, and re-telling the story. Pro-social behavior test was conducted for collective comparison of pro-social behaviors, and ANCOVA was conducted to investigate the difference between groups. As a result, the young children of the experimental group participating in the cartoon-oriented storytelling activities showed a significantly higher pro-social behavior than the young children of the comparative group. Therefore, it was found that the cartoon-oriented storytelling activities designed in this study had a positive effect on promoting pro-social behavior of young children. This suggests that it can be used appropriately as a suitable teaching-learning method in kindergarten education field.

The multinomial logit model has been applied for various choice problems. Among others, the joint destination mode choice, the mode choice and the route choice are the three major modeling topics for korean transportation planners. This paper examines with real world data (the Olympic road and its competing two major arterials) the usefulness of a Logit route choice model. Quites surpisingly, it is found that the multinomial route choice behavioral model calibrated for this study based on (0,1) individula data base can not provide a good estimate for O-D trips less than 6㎞. 400data points and 3case studies might not be sufficient for a sound conclusion. It is, however, believed from a series of similar studies conducted by the authors that the route choice behavior is more sensitive (more demand elastic with respect to travel time changes) than the mode choice and the shorter trip, the more sensitive. The travel time parameters for destination choice models are usually smalle than the travel time parameters for mode choice models and these parameters (for mode choice models) turn our smaller than the travel time parameters for route choice models from this study. Table 2 in this paper shows parameter changes for three different markets and Table 3 shows the modeling errors when the estimated individual probabilities are aggregated into a route level.

도시고속도로 램프미터링을 위한 진입극대화방안과 진출극대화방안의 비교 연구
이인원,김대호 대한교통학회 1996 大韓交通學會誌 Vol.14 No.4
The optimal solution obtained by a linear programming model is to maximize the ramp inflow rate. It is argued in this paper that the maximization of inflow rate is different from the maximization of outflow rate under congested conditions. Therefore, this paper proposes a systematic searching procedure from a linear programing formulation to a integer programming : first obtain the optimal solution by a linear programming and then adding weight to linear programming then. solve the optimal solution again by integer programming i.e. The proposed method is an interactive approach. Measure of effectiveness by simulation models regards the real time data(O/D, queue, delay, etc), can be utilized in the proposed interactive process.

Stochastic Dynamic Assignment 모형의 개발과 활용
이인원,정란희 대한교통학회 1993 大韓交通學會誌 Vol.11 No.1
A formulation of dynamic traffic assignment between multiple origins and single destination was first introduced in 1987 by Merchant and Nemhauser, and then expanded for multiple destination in the late 1980's (Carey, 1987). Based on behavioral choice theory which provides proper demand elasticities with respect to changes in policy variables, traffic phenomena can be analysed more realistically, especially in peak periods. However, algorithms for these models are not well developed so far(working with only small toy network) and solutions of these models are not unique. In this paper, a new model is developed which keeps the simplicity of static models, but provides the sensitivity of dynamic models with changes of O-D flows over time. It can be viewed as a joint departure time and route choice model, in the given time periods(6-7, 7-8, 8-9 and 9-10 am). Standard multinomial logit model has been used for simulating the choice behavior of destination, mode, route and departure time within a framework of the incremental network assignment model. The model developed is workable in a PC 386 with 175 traffic zones and 3581 links of Seoul and tested for evaluating the exclusive use of Namsan tunnel for HOV and the left-turn prohibition. Model's performance results and their statistical significance are also presented.
