화물차량의 통행패턴은 여객통행에 비해 연구 성과의 누적이 상대적으로 적은 분야이다. 그럼에도 불구하고 도시 내 통행에서 화물차가 차지하는 중요성에 대한 인식이 증가하고 있으며, 자가용 화물 차주들의 능동적 사업 비율이 증가하고 있어 이 분야에 대한 더 많은 연구의 필요성이 대두된다. 본 연구는, 여객통행에서의 활동기반 수요추정 이론의 발달에 부합하는 화물통행에서의 의사결정 원리에 대한 연구의 기초로서, 화물차량 통행실태 조사의 자료를 분석하여 화물차량 톤급별 평균 통행 특성, 운행효율성, 도착지-도착지유형-적재품목 통행연쇄의 특성을 확인하였다. 분석 결과 이들 화물차량 통행 특성들은 톤급별로 분명한 차이가 있음을 확인하였으며, 그 자체 화물차의 톤급별 특징을 잘 보여주었다. 연구 결과는 화물차량 통행 관련 교통정책 수단 개발에 긍정적 기여를 할 수 있을 것으로 기대된다.

본 연구는 목적지 다변화 정도를 기준으로 통행격차를 정의하고, 사회경제적 요인과 공간적 요인이 고령층의 통행격차에 미치는 영향을 분석했다. 특히 기존 연구에서 주목하지 못한 동시간대에서의 통행격차를 분석하기 위해 통행집단 간 반응의 차이를 유도할 수 있는 COVID-19를 자연실험의 사례로 활용했다. 본 연구에서 서울시 지하철 교통카드자료를 이용하여 COVID-19 이전의 통행격차(2018~2019)와 이후의 통행격차(2019~2020)를 비교한 결과는 다음과 같다. 아침시간대(4:30-9:00)의 경우, 거주지의 중심성에 따른 목적지 다변화 격차가 COVID-19 전후로 변함없이 나타났으며, 이는 도시기능이 도심에 집중되어있는 불균등한 도시공간구조로 인해 COVID-19 이전부터 서울의 중심부와 주변부 간에 목적지 다변화 격차가 존재했기 때문이다. 한편 오전시간대(9:00-12:00)의 경우, COVID-19 이전에는 별다른 격차가 나타나지 않은 반면, 이후에는 교육수준과 거주지의 접근성에 따른 목적지 다변화 격차가 새롭게 나타났다. 기본적으로 사회경제적 수준과 거주지의 중심성이 높을수록 이용할 수 있는 도시 어메니티가 다양하고 목적지에 대한 선택의 폭이 넓지만, COVID-19 이전에는 목적지를 자유롭게 선택할 수 있는 여가통행의 특성상 선택의 폭 차이가 목적지 다변화 격차로 이어지지 않았다. 반면 COVID-19 이후 제약환경 하에 새로운 목적지를 찾아야 하는 상황에서는 선택의 폭이 목적지 다변화에 중요한 영향을 미치는 요인으로 작용했다. 이와 같은 분석을 통해 본 연구는 COVID-19 대유행기에 나타난 동시간대에서의 통행격차가 COVID-19 이전부터 사회경제구조와 도시공간구조에 의해 형성되어온 선택의 폭 차이에 기인함을 시사한다.

This study aims to provide a methodological framework to estimate the travel demand of hazardous materials transporting vehicles by link and analyze daily traffic patterns on an expressway to develop safety roadway management strategies. Traffic volume of hazardous material vehicles is counted through the on-site investigation at twenty-five tollgates on the expressway, and their demands by a link are predicted through origin-destination flows estimation. The result shows that the number of the domestic hazardous materials vehicles is approximately 51,207 vehicles per day and it indicates that hazardous materials transport vehicles account for 1.5% of total daily traffic on the internal expressway and 6.2% of total cargo traffic volumes. This study roughly estimated how many hazardous materials vehicles pass through the expressway segment. Thus it is expected to be utilized for establishing a systematic highway management strategy in the future by calculating the traffic volume of the hazardous material vehicles traveling on the interstate expressway.

국내외 여행자가 늘어나는 추세이다. 여행 전부터 조사하여 계획을 짜는 사람들, 여행을 떠났으나 길을 몰라 목적지를 잘 찾지 못하는 사람들이 존재한다. 이러한 문제점을 해결하고자 본 논문에서는 스마트폰 애플리케이션을 통해 여행에서의 이동 간 효율성을 제공한다. 동시에 편리함, 만족감 등을 향상시키기 위해 여행 시스템을 통하여 국가와 목적지를 선택하고 선택한 여러 목적지 중 현재 사용자의 위치에서 최단 경로에 위치한 목적지를 안내하여 여행 경로를 단축시키고 시간을 절약한다. 또한 부가적인 시설의 위치를 안내해주는 편의성을 제공하고자 구현하였다.

In most cities, travel demand is distributed along long corridors and its destinations tend to concentrate in a central business district. For this kind of many-to-one or one-to-many travel demand pattern, a zonal operation of buses can be an efficient bus operation technique in which a long bus-demand corridor is divided into service zones and each service zone is provided with its own bus route connecting the service zone and single destination separately. This paper develops models of the total transportation costs for a single-zone operation and 2-zonal operation of buses for a long demand corridor with single destination in terms of various cost parameters, demand density, bus operation speeds, and location of the boundary between two service zones. In this study the total transportation cost is assumed to consist of the bus operation cost, passenger waiting cost and passenger travel time cost. It was proved that a zonal operation of buses can be more efficient than a single-zone operation for certain circumstances of the system and an boundary condition between two operation techniques was obtained. Also, several case studies were performed for various values of the cost parameters.

This study aims to empirically identify the effect of spatial accessibility, based on travel, on housing prices in the Korean capital region. More specifically, it has two research purposes: First, investigating the effect of comprehensive spatial accessibility, based on road network and actual trips from origin to destination, on average apartment price (Korean Won per square meter) at the level of Eup, Myeon and Dong; Second, identifying better accessibility index between Hansen's and Kalogirou and Foley's ones. The former represents a road-based travel time decay function with destination trips, while the latter is a function with origin trips as well as destination ones. The study employs spatial economic models considering spatial auto-correlative relationship as an appropriate methodology with such control independent indicators as population density, road density, educational environment and distances from CBDs. Analysis results demonstrate that spatial accessibility, based on road network and actual trips from origin to destination, has a statistically significant impacts on housing price in the region. Our empirical evidence proves that the Hansen index is more appropriate than the other in estimating housing price impacts.

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.

When people go to travel, sometimes one writes many articles about the destination. Existing travel information services such as Blog, Internet Cafe, and SNS are difficult to provide realistic information since the provided information may not be a place directly on the road. This paper presents a travel information system including recommended courses, theme courses, and travel map. In addition, the proposed system can provide the functions of writing, reading, and deleting a message note that stores the travel information based on the augmented reality if a defined marker among the community members is recognized in a smartphone App. Therefore, this paper can present an implementation method for new community system using augmented reality and image processing as well as providing the conventional travel information services, and allows the user to take advantage of the realistic and accurate information.

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.
