ENSURING SAFE AND SMOOTH TRAFFIC FLOW FOR NATIONAL RESILIENCE USING DIGITAL TECHNOLOGY

Abstract

 In recent years, the impacts and damages caused by localized heavy rainfall associated with climate change have been reported, highlighting the importance of appropriate weather information sharing. Addressing these issues is an urgent task for national resilience, requiring suitable measures in road traffic and business operations. Meanwhile, the promotion of digital transformation (DX) using digital technologies such as virtual spaces is anticipated. This study identifies the challenges in disseminating weather information to vehicle drivers to ensure safe and smooth traffic flow using digital technology. Specifically, it examines the understanding of rainfall intensity defined by the Japan Meteorological Agency through questionnaire interviews with participants. Furthermore, the study investigates the impact of different environmental conditions, such as rainfall, on vehicle drivers using driving simulations with BIM/CIM models constructed during road design. It also considers future speed regulations during rainfall. The results using BIM/CIM suggest the importance of setting speed regulations that take into account differences in rainfall and other driving environmental conditions.
