도시교통문제의 주원인은 급격한 자가용 승용차 이용의 증가이다. 이를 해결하기 위한 방안으로 혼잡통행료의 징수, 나홀로 차량 단속 등 강력한 교통수요관리정책들이 대두되고 있으나, 이제는 공공기관과 승용차 이용자의 직접적인 커뮤니케이션을 통해 이용자 스스로가 교통행동의 변화를 일으킬 수 있는 방안을 모색해볼 필요가 있다. 이를 가능하게 하는 기법으로 개개인의 의식변화를 통해 행동변화를 유도함으로서 합리적인 승용차 이용을 도모하는 모빌리티 매니지먼트(MM: mobility management)가 최근 해외에서 실시효과가 검증되고 있다. 따라서 본 연구는 개인의 자발적인 행동변화를 중시하는 MM의 국내도입이 현 시점에서 필요하다고 판단하여, 기법에 대한 기초적인 연구로서 승용차 이용자의 자발적인 교통행동변화 유도방안을 살펴보기 위해 교통분야 전문가를 대상으로 설문조사를 실시하였으며 AHP기법을 활용해 자발적인 교통행동변화 유도방안의 우선순위를 산정하였다. 분석 결과 대중매체를 활용하여 교통행동을 변화해 줄 것을 적극적으로 호소하는 방안이 1순위로 나타났으며, 다음으로 교통행동의 변화를 위한 회사대상 교육실시, 학교대상 교육실시, 지역단위의 소규모 워크숍 개최의 순으로 높은 상대적 중요도를 보였다.

This paper presents a simulation tool for developing and evaluating automated driving systems' lane change algorithm in urban congested traffic. The behavior of surrounding vehicles was modeled based on driver driving data measured in urban congested traffic. Surrounding vehicles are divided into aggressive vehicles and non-aggressive vehicles. The degree of aggressiveness is determined according to the lateral position to initiate interaction with the vehicle in the next lane. In addition, the desired velocity and desired time gap of each vehicle are all randomly assigned. The simulation was conducted by reflecting the cognitive limitations and control performance of the autonomous vehicle. It was possible to confirm the change in the lane change performance according to the variation of the lane change decision algorithm.

The propose of this study is to analysis driver's behavior of traveler information. This research made an attempt to explore driver's route change behavior in the en-route stage. Model were developed for each analysis with LIMDEP software which was developed by Willams H Greene. Commuters' transportation change in before trip stage are affected by their income, travel time, and incident information and constant of this model showed their reluctance of change mode. This was resulted from the inappropriateness of traffic information to general commuters which is the main target of traffic information.

The mission of the police as described by law is to guard the life, body and property of all citizens. Such duties should be accurately performed based on legal and democratic procedures because the works of the police are directively influencing the overall lives of the citizens by restricting their freedom. We are frequently watching the traffic police on the street or road. Traffic policing aims to reduce crime and the opportunities for criminal activity in relation to the use of roads, that is to improve road user behavior in order to reduce accidents. The characteristics of traffic accident change is not similar in each traffic condition. The purpose of this study is to analysis a type characteristics of traffic accident change, such as number of deaths and wounded persons by the time, the vehicle, the type the road, the age group. Based on the characteristics of traffic accident change, traffic accident countermeasures are proposed, in which some variable of traffic policies such as traffic facilities, traffic regulation, and traffic safety education.

PURPOSES : The purpose of this study is to check the possibilities of traffic pattern analysis using MatSIM for urban road network operation in incident case. METHODS : One of the stochastic dynamic models is MatSIM. MatSIM is a transportation simulation tool based on stochastic dynamic model and activity based model. It is an open source software developed by IVT, ETH zurich, Switzerland. In MatSIM, various scenario comparison analyses are possible and analyses results are expressed using the visualizer which shows individual vehicle movements and traffic patterns. In this study, trip distribution in 24-hour, traffic volume, and travel speed using MatSIM are similar to those of measured values. Therefore, results of MatSIM are reasonable comparing with measured values. Traffic patterns are changed according to incident from change of individual behavior. RESULTS : The simulation results and the actual measured values are similar. The simulation results show reasonable ranges which can be used for traffic pattern analysis. CONCLUSIONS : The change of traffic pattern including trip distribution, traffic volumes and speeds according to various incident scenarios can be used for traffic control policy decision to provide effective operation of urban road network.

본 연구에서는 연령에 따른 운전자의 운전확신수준 변화가 운전행동에 미치는 영향을 살펴보았다. 운전확신수준을 측정하기 위해 운전확신수준 설문지를 사용하였으며, 조사대상자들의 운전경력, 주행거리, 운전일수, 법규위반(음주, 과속), 교통사고경험(가해, 피해)을 함께 조사하였다. 조사대상자는 만 19세부터 만 80세까지였으며 총 1,055명이 연구에 참여하였다. 운전확신수준의 구조를 알아보고자 요인분석을 실시하였다. 각 연령(29세이하, 30-39세, 40-49세, 50-64세, 65세이상)의 운전확신수준을 비교하고, 운전확신수준과 운전행동과의 관계를 알아보았다. 그 결과, 운전확신수준은 '상황둔감성', '불안전운전', '주의집중소홀', '운전자신감'의 네 요인으로 이루어져 있었으며, 연령의 증가와 함께 운전확신수준은 감소하는 경향을 보였다. 또한, 운전확신수준은 연령과 가해교통사고, 피해교통사고, 운전기간, 음주운전, 과속운전, 운전경력 등과 상관관계를 가지고 있었다. 연구에 참여한 운전자 집단을 음주운전집단, 과속운전집단으로 나누어 운전확신수준과 운전행동의 차이를 알아보았는데, 음주운전이나 과속운전 경험이 없었던 운전자 집단과 음주운전이나 과속운전을 경험한 운전자 집단의 운전확신수준과 운전행동이 유의한 차이를 보이는 것으로 나타났다.

Geographical Indication (GI) has been used with the expectation to influence customer buying behavior. In this research, we empirically investigate if such relationship exists using apple price changes in Korea along with web search traffic reflecting customers' interest in GI. The experimental results indicate that the apple price of the past, apple supply and web search traffic including GI name were significant on the prediction of price change of Chungju while web search traffic of regional name and that of product were significant for Cheongsong apples with GI. In Yeongcheon with no GI, the apple price of the past turns out to be significant only. The results indicated that interests in GI can help the price prediction but the regional name itself can play the same role, if the GI product is well known in association with the region.

도심 교통체증 감소와 물류의 신속한 이동을 위해 1990년대 초반 등장한 퀵서비스산업은 이륜자동차의 증가를 가속화 했으며, 경제발전에 따라 250CC 이상 대배기량의 이륜자동차들도 레저용으로 급증하고 있는 추세를 보이고 있다. 사고발생추세에서 전체교통사고대비 2005년 5.7%, 2008년 8.3%로 점차 증가추세를 보이며 사망률 또한 증가하고 있다. 본 연구에서는 이륜자동차의 자동차전용도로 통행에 대한 위험도를 알아보고자 서울시 연속류 도로를 대상으로 이륜자동차의 법규위반율과 차로변경 행태, 주행속도 행태를 분석하였으며 사고시의 차량충격량을 PCCRASH 시뮬레이션으로 산출하였다. 분석 결과, 차로변경시간과 평균통행속도가 일반차량과 상이하며 도로정체가 발생할 경우 부적절한 주행행태를 보이는 것으로 나타났다. 정부의 이륜자동차 자동차전용도로 허용 검토에 있어 본 연구는 허용여부를 판단하는데 도움이 되며 이륜자동차의 주행 행태를 연구하는데 기초자료로 활용할 수 있다.

The traffic accidents of the aged are increasing because old people generally experience a decline of physical functions and judgment but their dependence on automobiles increases. In order to investigate the older drivers' response to traffic signs and surrounding environment according to changing driving brightness, this study measured the visual cognitive behavior, driving behavior, and subjective evaluation while the driving brightness was changed using a driving simulator. Furthermore, the drivers who recognized traffic signs and those who did not were compared. As a result, it was found that some older drivers had declined ability of cognition, some failed to adapt to rapid brightness change even if sufficient attention was given to traffic sign, and some could not safely control the vehicle when approaching intersections. Therefore, the development of support systems for aged drivers in traffic environment is necessary in the future.

Recently, some research has been done to analyze the asymptotic behavior of queue length distribution in ATM (Asynchronous Transfer Mode) multiplexer. In this paper, we relate this asymptotic behavior with the asymptotic behavior of decreasing cell loss probability when the buffer capacity is increased. We find with reasonable assumptions that the asymptotic rate of queue length distribution is the same as that of decreasing cell loss probability. Even under different priority control schemes and traffic classes, we find that this asymptotic rate of the individual cell loss probability of each traffic class does not change. As a consequence, we propose the upper bound of cell loss probability of each traffic class when a priority control scheme is employed. This bound is computationally feasible in a real-time. The numerical examples will be provided to validate this finding.
