In the process of building the future of smart cities, innovation in mobility and road infrastructure is one of the most important topics. In particular, with the proliferation of autonomous vehicles and various types of mobility on the road, such as electric bicycles, electric kickboards, and electric wheels, roads have a variety of actors to accommodate, including traditional cars and pedestrians, and conflicts between them need to be resolved. Complete streets, a term coined in the United States in 2003, refers to the design and operation of roads that consider the equitable safety and convenience of all road users, including pedestrians, bicyclists, public transportation users, personal mobility (PM) users, and automobile drivers. Currently, many cities overseas are implementing complete streets, and research is being actively conducted to institutionalize them. However, there is a lack of research and discussion on complete streets in Korea. Therefore, this study aims to formalize the main factors to be considered in the design of complete streets by collecting and analyzing the opinions of academic and practitioner experts through the Delphi method. A total of three Delphi surveys were conducted, collecting free responses from experts through the first open-ended survey and organizing them into keywords to create the second and third closed-ended surveys. The second and third rounds of the survey consisted of a total of 52 questions, and 34 items out of 52 were selected as the final factors.

Since 2021, government departments have been promoting Automated Driving Technology Development and Innovation Project as national research and development(R&D) project. The automated vehicles and service technologies developed as part of these projects are planned to be subsequently provided to the public at the selected Living Lab City. Therefore, it is important to determine a spatial area and operation section that enables safe and stable automated driving, depending on the purpose and characteristics of the target service. In this study, the static Operational Design Domain(ODD) elements for Level 4 automated driving services were reclassified by reviewing previously published papers and related literature surveys and investigating field data. Spatial analysis techniques were used to consider the reclassified ODD elements for level 4 in the real area of level 3 automated driving services because it is important to reflect the spatial factors affecting safety related to real automated driving technologies and services. Consequently, a total of six driving mode changes(disengagement) were derived through spatial information analysis techniques, and the factors affecting the safety of automated driving were crosswalk, traffic light, intersection, bicycle road, pocket lane, caution sign, and median strip. This spatial factor analysis method is expected to be useful for determining special areas for the automated driving service.

Because most applications of vision-based object tracking demonstrate satisfactory operations only under very constrained environments that have simplifying assumptions or specific visual attributes, these approaches can't track target objects for the highly variable, unstructured, and dynamic environments like a traffic scene. An adaptive fusion framework is essential that takes advantage of the richness of visual information such as color, appearance shape and so on, especially at cluttered and dynamically changing scenes with partial occlusion[1]. This paper develops a particle filter based adaptive fusion framework and improves the robustness and adaptation of this framework by adding a new distinctive visual attribute, an image feature descriptor using SIFT (Scale Invariant Feature Transform)[2] and adding an automatic teaming scheme of the SIFT feature library according to viewpoint, illumination, and background change. The proposed algorithm is applied to track various traffic objects like vehicles, pedestrians, and bikes in a driver assistance system as an important component of the Intelligent Transportation System.

Increased investment in environment-friendly transport vehicles has led to rapid transit of railway tracks, double track program, linear improvements in railway lines, and moving railroad routes into the suburbs. They resulted in fast increase of railway yards. However, as the railroad yards being neglected, urban fine sites have been degraded. Local governments kept seeking ways to utilize the railway yards. In addition, Ministry of land, infrastructure and transport enacted "Guidelines for utilization of railway yards". The Guidelines categorized the railway yards into three types; conservation, utilized, and other sites in order to make efficient use of them. The railway yards have been converted and used for parks, rail bike trails, bike paths, and solar projects. It seems that studies are needed on diverse use of the yards and on post evaluation. This study investigated current uses of railway yards, domestic and foreign, and analyzed for the pertinent conditions on natural and cultural landscape, educational value, location and accessibility, potential for recreational area, and development opportunities. In this study, I proposed a quantitative evaluation method, and to find way to diversify the use of railway yards.

최근 한강, 낙동강, 금강, 영산강 등 주요 하천에 설치된 다기능 보는 평수위 및 홍수위의 수위차를 상당히 감소시켰으며, 가동보 운영으로 홍수초기 일정기간동안 수위를 조절할 수 있으므로 친수 목적으로 활용할 수 있는 고수부지 공간과 보로 인하여 유지되는 수면공간 등 새로운 가치를 창출할 수 있는 하천공간이 조성되었다. 새롭게 펼쳐진 하천공간을 다양한 여가 및 문화활동 공간으로 이용하고자 하는 국민적 요구가 증가함에 따라 공원 캠핑장 자전거도로 등 하천내 친수지구를 안전하게 관리해야할 필요성 또한 증가되었으므로, 본 연구에서는 영산강 친수지구를 대상으로 침수예측 현황 및 개선방안을 검토하였다. 지금까지의 국내 하천 홍수관리 정책은 하천의 홍수피해로부터 하천변 저지대의 범람피해를 최소화하는 방향으로 추진되었다. 이에 따라 홍수예보 또한 홍수주의보, 홍수경보 등 비교적 규모가 큰 홍수를 대상으로 사전에 예측하여 발령함으로써 홍수피해를 대비하는 것이 목적이었다. 그러나 하천 친수지구 침수는 지금까지의 홍수예보와는 대상홍수 유량규모에서부터 큰 차이를 나타낸다. 본 연구에서는 친수지구 지형 반영 개선, 지류 유입량의 민감도 분석을 통한 주요 지류유입 유량의 정확도 개선, 다기능 보 운영에 따른 보 배수영향의 반영 등을 통하여 현재 국토교통부의 홍수예측 모형인 FLDWAV 모형의 홍수위 예측 정확도를 개선하였다. 그 결과, 황룡강 합류 상류구간과 하류구간 모두 침수시작 시점의 포착, 수위수문 곡선의 형태 등 다양한 관점에서 수위해석의 정확도가 개선되었다. 삼지 지점의 경우, 홍수초기 수위해석 오차가 크게 줄어서 RMSE가 1.33m에서 0.30m 홍수해석 정확도가 개선되었으며, 광주지점의 경우의 RMSE는 1.60m에서 0.56m로 개선되었다. 황룡강 합류 하류 지점인 본동과 나주지점의 RMSE는 각각 0.30m, 0.39m에서 0.02m, 0.42m로 수정되었으며, 나주지점의 경우 저유량 규모에서 모형의 보정이 좀 더 수행될 필요가 있음을 확인하였으나 침수시점의 포착(본동 7.8 EL.m, 나주 4.0 ELm)에서 크게 개선됨을 확인하였다.
