Traffic accident analysis using Geographic Information System (GIS) and 3D scene technology can effectively identify accident hotspots and provide a scientific basis for formulating road safety improvement measures. Combining 3D scene technology, a virtual model of the traffic accident scene can be created, which is not only useful for accident reconstruction and analysis, but also provides an intuitive perspective for identifying accident hotspots.

With GIS technology, traffic accident data can be mapped to specific points and heat maps can be created to show the frequency of accidents. Wings Engine's 3D scene technology allows these areas to be observed from different angles, which helps analyze accident patterns and causes.

Based on the results of GIS and 3D scene analysis, a series of road safety improvement measures can be formulated, such as:

Improve road design: Add more road signs in accident hotspots, improve road lighting, and optimize road design.

Strengthen traffic rules: Strengthen traffic enforcement at times and places where accidents are frequent.

Public education: Improve awareness of road safety, especially to raise risk awareness in accident hotspots.

Technological intervention: Install smart traffic systems such as vehicle speed control systems and traffic surveillance cameras in accident-prone areas.

After implementing these measures, regular monitoring and evaluation should be carried out using GIS technology to confirm the effectiveness of the improvements. Wings Engine's 3D scene technology can also be used to simulate the effects of different improvement measures to support decision-making.

GIS and 3D scene technology play an important role in traffic accident analysis and prevention in Japan. The application of these technologies can improve the safety of road users by more accurately identifying accident-prone areas and formulating effective road safety improvement measures.
