Purpose: The purpose of this study is to explain the pivotal role of the travel forecasting process in urban transportation planning. This study emphasizes the use of travel forecasting models to anticipate future traffic. Method: This study examines the methodology used in urban travel demand modeling within transportation planning, specifically focusing on the Urban Transportation Modeling System (UTMS). UTMS is designed to predict various aspects of urban transportation, including quantities, temporal patterns, origin-destination pairs, modal preferences, and optimal routes in metropolitan areas. By analyzing UTMS and its operational framework, this research aims to enhance an understanding of contemporary urban travel demand modeling practices and their implications for transportation planning and urban mobility management. Result: The result of this study provides a nuanced understanding of travel dynamics, emphasizing the influence of variables such as average income, household size, and vehicle ownership on travel patterns. Furthermore, the attraction model highlights specific areas of significance, elucidating the role of retail locations, non-retail areas, and other locales in shaping the observed dynamics of transportation. Conclusion: The study methodically addressed urban travel dynamics in a four-ward area, employing a comprehensive modeling approach involving trip generation, attraction, distribution, modal split, and assignment. The findings, such as the prevalence of motorbikes as the primary mode of transportation and the impact of adjusted traffic patterns on reduced travel times, offer valuable insights for urban planners and policymakers in optimizing transportation networks. These insights can inform strategic decisions to enhance efficiency and sustainability in urban mobility planning.

In recent years, energy consumption in the transportation sector by expanding motorization continues to increase in almost every country in the world. Moreover, the growth rate of the transportation energy consumption is significantly higher than those of the civilian and industrial sectors. Therefore, every country strives to reduce its dependence on private transport, which is the main contributor to the transportation energy consumption. In many countries, concepts such as Transit Oriented Development (TOD) or New Urbanism, which controls road traffic by increasing the proportion of the public transportation significantly, have been implemented to encourage a modal shift to public transport. However, the level of change required for eliminating environmental problems is a challenging task. Minimizing transportation energy consumption by controlling the increase of the traffic demand and maintaining the level of urban mobility simultaneously is a pressing dilemma for each city. Grasping the impact of the diversity of the urban transport and infrastructure is very important to improve transportation energy efficiency. However, the potential for reducing urban transportation energy consumption has often been ineffectively demonstrated by the diversity of cities. Therefore, the accuracy of evaluating the current efficiency rate of the urban energy consumption is necessary. Nevertheless, quantitative analyses related to the efficiency of transportation energy consumption are scarce, and the research on the current condition of consumption efficiency based on international quantitative analysis is almost nonexistent. On the basis of this background problem definitions, this research first built a database of the transportation energy consumption of private modes in 119 cities, with an attempt to reflect individual travel behaviors calculated by Person Trip data. Subsequently, Data Envelopment Analysis (DEA) was used as an assessment method to evaluate the efficiency of transportation energy consumption by considering the diversity of the urban traffic features in the world cities. Finally, we clarified the current condition of consumption efficiency by attempting to propose a target values for improving transportation energy consumption.

Currently, urban mobility is rather two-dimensional: Connections between transportation solutions like elevators, escalators, moving walks, and metro stations are static. In the future, urban mobility will require a holistic view: Seamless transportation, enabled by innovative IoT technology, is a necessity. A dialogue between the city, its buildings and transportation systems, considering the specific needs and preferences of each and every citizen, must be adopted. Travelling through the city will become a lot more individualized, interactive and customized to specific requirements.

경제적 효율성의 추구를 최고의 목표로 하는 자본주의 경제체제에서 생산과 소비의 과정은 가능한 한 '효율적'으로 수행할 필요성이 제기되며 이러한 과정에서 통행에 소요되는 시간은 일종의 '낭비'일 수 밖에 없다. 따라서 통행은 가능한 한 빠른 시간 내에 이루어져야 하며 이러한 조건을 충족시키기 위하여 자가용 등 차량에 의한 통행이 선호될 수 밖에 없다. 그러나 차량통행의 증가 특히 자가용 통행의 증가와 이에 따른 차량위주의 도시교통체계는 여러가지 형태의 사회적 문제를 유발하며 특히 차량통행의 증가에 따른 지역사회의 황폐화, 계층간 접근성 및 이동성의 차등화 등의 측면에서 상당히 부정적인 영향을 유발하고 있는 실정임에도 불구하고 우리 나라에서 이에 대한 체계적인 연구는 거의 전무한 실정이다. 이러한 배경에서 본 연구는 우리사회에서 교통으로 인하여 발생할 수 있는 사회적 영향들을 체계적으로 분석하기 위한 기초작업의 일환으로 교통으로 인하여 유발되는 사회적 영향들의 형태와 이에 따른 문제점들을 제기하고 이러한 문제들을 해결하기 위한 앞으로의 연구 방향을 제시하는 데 그 목적이 있다.

우리나라는 고령화 추세의 가속화로 인한 도시철도의 노인무임수송 급증이 만성적 적자를 초래하는 이유가 되고 있다. 도시철도의 노인무임수송으로 인한 지속적 적자가 앞으로도 예상되는 가운데 같은 대중교통 수단인 버스의 경우 노인인구에 대해 일반요금을 부과하고 있는 반면, 도시철도만 무임수송을 행하고 있다는 점은 대중교통 이용 요금체계 상의 형평성 문제를 제기할 수 있다. 따라서 본 연구는 노인층의 무임수송 및 대중교통 형평에 관한 의식조사를 실시하고, 도시철도와 버스간의 노인인구에 대한 요금체계 이원화에 따른 형평성문제의 대안으로 두 수단 간의 적절한 요금비율의 도출을 통해 도시철도와 버스를 함께 이용할 수 있는 방안을 제시해 노인무임수송으로 인한 문제를 개선할 수 있는 방안을 도출하고자 한다. 이와 같은 대안은 공기업이 자주성 있는 경영을 할 수 있게 함과 동시에 대중교통수단 간의 형평의 문제도 개선할 수 있는 방안으로 도시철도의 노인무임수송으로 인한 만성적자를 개선할 수 있는 여러 방안 중 하나가 될 수 있을 것이다.

Recent developments in combining transportation planning models and input-output approaches, together with inclusion of intensity of land uses, have made it possible to construct realistic comprehensive urban and regional activity models. These modes form the basis for a rigorous approach to studying the interactions among urban activities. However, efficient computational solution methods for implementing such comprehensive models are still not available. In this paper an efficient solution method for the urban activity model is developed by combining Evans' partial linearization technique with Powell's hybrid method. The solution algorithm is applied to a small but realistic urban area with a detailed transportation network.

Recently, the number of consumers using digital online distribution platforms is increasing. This caused the rapid growth of the e-commerce market and increased delivery volume in urban areas. The logistics system, designed ar006Fund the city center to handle the delivery volume, operates a delivery system from the outskirts of the city to the urban area using cargo trucks. This maintains an ecosystem of high-cost and inefficient structures that increase social costs such as road traffic congestion and environmental problems. To solve this problem, research is being conducted worldwide to establish a high-efficiency urban joint logistics system using urban railway facilities and underground space infrastructure existing in existing cities. The joint logistics system begins with linking unmanned delivery automation services that link terminal delivery such as cargo classification and stacking, infrastructure construction that performs cargo transfer function by separating from passengers such as using cargo platform. To this end, it is necessary to apply the device to the vertical and horizontal transportation machine supporting the vertical transfer in the flat space of the joint logistics terminal, which is the base technology for transporting cargo using the transfer robot to the destination designated as a freight-only urban railway vehicle. Therefore, this paper aims to derive holistic viewpoints needs for design requirements for vertical and vertical transportation machines and freight transportation standard containers, which are underground railway logistics transport devices to be constructed by urban logistics ecosystem changes.

As of July 1997, the registered number of automobiles exceeded 10 million and Korean auto industry produced 2,850,000 cars. Many environmentalists warn that the passenger cars are not sustainable urban transportation system in large cities. The cars produce about 80% of air pollutants, and consume 30% of petroleum imported. For the past 30 years the administration increased the road system, but the length of road per car is decreased from 813m in 1965 to 9m in 1995. The cost of traffic congestion was estimated to be \14.7 trillion in 1996, and is feared to increase without changing the present transportation system. The undesirable impact of cars include the casualties from traffic accidents, insurance loss, and separation of human relatioships. To construct sustainable urban transportation system, three principles should be followed. The first principle is to make the urban streets walkable for the people. The second principle is to encourage bicycling. Roads and traffic systems should be designed to let bicylces travel safely. The third principle is to supply more buses and construct integrated transportation system based on buses. The subway system is too expensive to construct and without the support of a well-organized bus system it may not work efficiently. The Brazilian city of Curitiba has constructed a very efficient bus system only with 1/80 of the estimated cost of subway system. The car-oriented transportation system does not seem to be an envrironmentally sustainable transportation system in most of the Korean cities.
