[Ph.D. Dissertation Defense] Ph.D.Candidate Sujin Lee AbstractUnderstanding functional regions resulting from interactions between people and regions is crucial for effective city planning and transportation management. Addressing potential deviations from planned functional regions, this study focuses on identifying how people actually utilize regions based on travel demand patterns. We propose a research framework consisting of three […]
[Ph.D. Dissertation Defense] Ph.D.Candidate Eunjeong Ko AbstractWhile traveling on the road, vehicles often encounter sections where different traffic streams converge together due to the geometric structures. These sections require decisions to be made in a short period of time to ensure smooth driving, so vehicle interactions are inevitable, which can lead to safety issues. Therefore, […]
Program: 2024 Outstanding Mid-Career Research Grant Program Title: Operation Strategy of Connected Autonomous Vehicles (CAVs) based on Mechanism for Traffic Congestion in Uninterrupted Traffic Flow Funder: NRF Funding: 700 million won Project year: 2024-2027 Project manager: Prof. Kitae Jang Abstract Uninterrupted traffic flow roads, exemplified by highways, are roads where vehicle movement is determined solely […]
Abstract: Current activity-based modeling (ABM) has two major limitations. First, ABM conventionally relies on household travel survey (HTS) data, which suffers from low spatial heterogeneity due to a low sampling rate (e.g., 1-5% of the population) and a low collection frequency. This issue results in a poor spatial resolution of generated and forecasted travel demand. Second, […]
