이광봉 公州大學校 大學院 2011 국내석사

최근 추세를 보면 차량의 원활한 흐름뿐만 아니라 보행자 및 자전거의 흐름과 안정성도 중요시 되고 있다. 그러나 현재 대부분의 교통신호는 차량을 우선으로 설계되었으며 보행자 중심의 설계 개념은 활발히 도입되지 않고 있다. 보행자신호는 차량위주의 신호 설계 값에 의해 보행신호를 제공하거나 보행자통행량이 적은 경우 Push-button에 의해 보행자 신호 요청 시 신호를 제공하는 방법이 이용되고 있다. 하지만 이러한 방법들은 보행자우선의 신호운영 개념은 아니기 때문에 보행자의 지체를 줄일 수 없다. 이에 본 연구에서는 보행자 지체를 최소화 하되 기본적인 차량의 흐름은 유지할 수 있는 방법을 제시하고자 한다. 본 연구에서는 횡단보도가 설치된 2차로(양방4차로) 연동화가로구간(coordinated arterial section)을 가정하여 분석하였다. 교통류의 특성을 보면 차량 추종모형이론(Car Following model)에 의해 차량군이 형성되어 이동을 하며 교통량이 많거나 적어지기를 반복한다. 이러한 특성으로 인해 교통량이 적을 경우에도 불필요한 녹색시간을 차량에게 제공하는 것이 일반적이다. 이런 불필요한 녹색시간(green time)을 차량이 아닌 보행자에게 제공함으로써 보행자의 지체를 최소화 할 수 있다. 보행자신호를 제공하기 위한 조건은 차두시간(head way)이 3초 이상이 될 경우로 한다. 차량현시(phase)는 연동유지를 위한 최소녹색시간을 제공함으로서 차량군이 형성된 차량의 흐름은 유지한다. 보행자신호는 교통량의 변화에 따라 녹색시간이 변화 되며 교통량이 적을 경우 녹색시간은 최대한 늘어나고 교통량이 많다하더라도 최소보행자신호 시간은 제공함으로써 보행자 위주의 교통운영이 가능해 진다. Recent trend shows that the smooth traffic flow is important but flows and safety of pedestrians and bicycle are also important. However, most present traffic signal is designed for vehicle and the design concept for pedestrians is not introduced vigorously. the pedestrian signal provides it by vehicle-concerned signal design value or when pedestrian flow is small, the signal is provided by Push-button. But these methods are not the concept of pedestrian-first so it cannot reduce delay of pedestrian. Therefore this study want to suggest the methods that minimize delay of pedestrian but maintain basic traffic flow. This study supposed that a crosswalk is in a coordinated arterial section and analysed it. When we see properties of traffic flow, vehicle platoon is formed and traffic is increased or reduced by Car Following model. Because of this property, it is common that unnecessary green time is provided to vehicle when traffic is small. As this unnecessary green time is provided to pedestrians not vehicle, we can minimize delay of pedestrian. The condition to provide pedestrian signal is that head way is 3 seconds. Phase maintains traffic flow as it provides minimum green time for keep coordinated. the pedestrian-concerned traffic operation can be possible when green time is changed by traffic-if traffic is small, green time will be maximized and if traffic is big, minimum pedestrian signal time will be provided.

As the motorcycle usage has increased for its conveniency on small freight forwarding business recently, a new transportation problem has emerged with the illegal occupation of the road area by motorcycle parking. Nevertheless, there does not exist the installation standards for motorcycle parking and its legal ground. This study aims to suggest the legal and institutional ground for motorcycle parking, and the standards and suppliable number of the motorcycle parking lot. Firstly, an analysis on the specification of motorcycle and human body was conducted to assess the motorcycle parking lot standards. Based on it, this study suggests the optimal installation standards and area demands. Secondly, this study attempted to build a multivariable linear regression model to assess the demand of motorcycle parking of the Bangsan-market, which generates a lot of the motorcycle parking for small freight forwardings. However, the model could not satisfy the significant level of 10%, as the parking for the small freight forwardings take too short time to be a significant variable, and there exist the differences in sales even if the size of shop is substantially the same. Finally, this study suggest the amendments to give the legal ground to the motorcycle parking standards.

중국 대다수 도시의 교차로 신호운영방식은 아직까지 많이 뒤떨어져 있다. 대다수가 2현시방식으로 신호교차로의 운영방식에 대한 연구가 많이 부족하다. 도시 신호체계의 단순과 불합리는 운영 효율성뿐만 아니라 안전성까지 저하시킨다. 본 연구는 란주시에 위치한 두 개의 신호교차로를 대상으로 검토하여 안전성과 효율성 향상을 원칙으로 9개의 개선방안을 작성하여 분석하였다. 본 연구는 VISSIM을 이용하여 대상 4지 교차로와 3지 교차로로 구성한 네트워크 모형을 구축하였다. TRANSYT-7F로 신호주기 및 신호시간을 최적화하고, VISSIM으로 9개 개선방안 별 네트워크의 지체를 분석하였다. VISSIM에서 도출된 경로파일을 SSAM(Surrogate Safety Assessment Model)에 실행시켜 상충횟수를 도출하여 안전성을 평가하였으며, 차량 당 평균지체와 상충횟수를 종합하여 각 개선방안을 비교분석하였다. 본 연구의 대상 4지 교차로의 7개 개선방안은 모두 안전성이 제고되었다. 효율성을 보장하는 전제하에 안전성이 제일 높은 방안은 좌회전 교통량이 많은 부도로에 보호좌회전신호를 설치하고, 주도로에 비보호 좌회전신호 및 좌회전차로를 설치하는 5번 방안이 상충횟수가 989에서 482로 대폭 감소하는 것으로 분석되었다. 효율성 측면에서는 "all red"신호를 설치한 7번 방안이 대상교차로 지체가 109.07초/대 에서 72.85초/대, 전체 네트워크 지체가 121.82초/대에서 91.66초/대로 감소하여 제일 우수하였다. 3지 교차로의 두 방안은 RTOR(Right Turn On Red)신호에 NTOR(No Turn On Red)로 개선되었다. 안전성이 모두 개선되었고, 그 중 차량과 보행자의 상충점을 완전히 제거한 1번 방안이 효율성과 안전성 측면에서 제일 우수하였다. The operation of intersection traffic signal system is relatively undeveloped in most urban areas of China, where 2-phase operations have now widely been used in most intersection traffic signal systems. The research on this area remains on a low level. The non-efficiency and irrationality of operating intersection traffic signal system result in a decline of efficiency and safety of urban intersection operation system. By evaluating 2 intersection traffic signal systems located in Lanzhou, the capital city of Gansu, China, this study provides 9 improvement plans based on enhancing the safety and efficiency of the signalized intersection. In this study, a road network model was created for a 3-leg intersection, a 4-leg intersection with adjacent intersections via VISSIM. The improvements of cycle time, and signal phase time were calculated by traffic signal optimization software, TRANSYT-7F. Secondly, this research analyzed delays of the 9 plans by using road networks mentioned above. And vehicle trajectory files of these targeted intersections were exported. The number of conflicts was produced by importing vehicle trajectory files exported from VISSIM into SSAM(Surrogate Safety Assessment Model). Safety analysis of all these 9 plans was done using the number of conflicts, and the plans applied to these 2 intersection traffic signal systems were exported. The safety of 4-leg intersection has been increased by the seven improvement plans which have been proposed in this paper. In the premise of efficiency guarantee, the safest is No. 5 plan that left turning protected signal phase is set at minor road which possesses more traffic volume of left turning, meanwhile the left turning non-protected signal phase and left turn lane are set at main road. Through the analysis of applying the No. 5 plan, the number of conflicts has been decrease from 989 to 482. The No. 7 plan which applied “All red” signal, can decrease the delay from 109.07 seconds/vehicle to 72.85 seconds/vehicle, meanwhile the delay of all road network also is decreased from 121.82 seconds/vehicle to 91.66 seconds/vehicle. Through applying the No. 7 plan, the result of reducing the delay of all road network is the best. The two improvement plans of 3-leg intersection have changed the signal from RTOR(Right Turn On Red) to NTOR(No Turn On Red), improved the safety of the 3-leg intersection. From these two improvement plans of 3-leg intersection, the No. 1 plan which can remove the conflict points of vehicles and pedestrians, is the best because of the higher efficiency and safety.

Recently, the most widely used model in trip distribution is gravity model. Gravity model can provide a reasonable representation of trip patterns provided they can be explained mainly by the size of the generation and attraction power of zones and the deterrence to travel generated by generalised cost(distance or time). In some circumstances, there may be pairs of zones which have a special association, but gravity model can't explain that. So, there are many studys and arguments to solve this problem. Main steam of this study is utilizing significant variable. The purpose of this study is enhancement of reliability for trip distribution model(gravity) focused on choosing significant variable and mathematical application utilizing error term between observed data and estimation. Essential assumption of this study is that significant variables related with error term between observed data and estimation will have potential capacities to adjust gravity model. In this case, relation with error term refers to relation with volume of error. Therefore, significant variables can be selected by using error term and improved model will be calculated. This study proceed on essential assumption and obtain significant result.

In Chungcheongnam-do, the ratio of high-speed national roads against regular ones is higher than nationwide. In addition, the province has poor railroad conditions. Thus, most of the freight transport depends on vehicles. Chungcheongnam-do is the hub of international interchange in the region surrounding the Yellow Sea and the center of international transportation, which connects to the main regions of North East Asia. Thus, an increase in domestic and overseas trade volume is expected. The purpose of this study is to research the effects of road construction on total traffic and freight transport volume in terms of spatial structure based on these spatial and social backgrounds. In this study, three axes of Years 1997, 2002, and 2007 were established. The declination and percentage changes of each axis and the traffic ratio of regular national roads were analyzed. As a result, as roads have been newly built, the declination of each axis have decreased and the traffic ratio of each axis have changed. The percentage of regular national roads have changed as roads have been built. Since the construction of roads greatly affects changes in spatial structure, methods for traffic distributions need to be conceived in order to develop Korea in balance and to efficiently use financial resources. In addition, strategical systems or services will be needed to increase or decrease traffic volume.

In this Century, most of ports have been changing in order to keep up with change of the world. The ports are become larger, integrated with high technology because containers which pass through the ports are sharply increasing. Also, ports have been developing considering waterfront. Not to turn over the world wide competition of the ports, a renewal of Bukhang in Busan was promoted firstly in Korea. In this study, final draft renewal plan of Bukhang in Busan at this stage was compared with renewal plan of Hafencity in Germany in order to propose improved renewal plan of Bukhang in Busan. Renewal plan of Hafencity in Germany was very similar with Bukhang in Busan in terms of renewal period and direction. The aim of this study is to propose the systematic improvement plan on eco-friendly port development from the comparison between case of Germany that is known for advanced country in this field and Korean case. The renewal plan of Bukhang in Busan and plan of Hafencity, Hamburg in Germany were compared with in terms of land use plan, category of facilities and waterfront. In the case of Hafencity in Germany, that was developed keep up the geometrical characteristics. However, the land for Bukhang was formed by reclaiming. For the reclaiming, enormous money was needed and that is time consuming work. At this stage financial raising plan was not specified. If it were not enough financial support from Korean government, this will be a development thoughtless for the environment. Whole area of Hafencity was developed as a complex but in Bukhang was divided by land zone. There is enough residential area in Hafencity but that was not plan in Bukhang except for condominiums and hotels. In Hafencity, whole area; where people live in, was connected with waterfront. In Bukhang, Grand Park and artificial island were constructed. From this point of view, it can be found difference of cognition in the eco-friendliness of waterfront. The common point of both plans was in traffic system, such as connection between old city and newly developed city, introduction of new transportation system, easy approach to the central station and construction of pedestrian way. The most different aspect of both plans was sustainable development. Prior to confirm the plan of Hafencity, eco-friendly energy system introduction and environmental impact on surrounding area was investigated. However in the plan of Bukhang, use of existing facilities and plan of waterfront space was considered. There was no plan on the energy system and research on the environmental impact was conducted as primary level. There are three improvements in renewal plan of Bukhang. Those are specified development plan, consideration on the sustainable development and originality. When introduce foreign study and development plan, fundamental idea and system should have to be introduced firstly. Also, confirmed development plan should have to be conducted with fundamental purpose though whole stage and not to be influenced by political issues. Moreover, financial raising plan have to be specified for the continuing conduction of this plan. In addition, specified energy plan and environmental impact of port development have to be investigated deeply. Finally, in the renewal plan of Bukhang, Korean tradition and culture should have to be considered in order to create the most Korean appearance and image.
