Description

Method and Electronic Device for Providing Traffic Flow Simulation Information Using Vehicle Type-Specific Traffic Volume Data The present disclosure relates to a method for providing traffic flow simulation information utilizing traffic volume information by vehicle type and an electronic device. Autonomous driving technology refers to a technology that enables a vehicle to drive autonomously with minimal or no human intervention by perceiving the surrounding environment using radar, LIDAR (light detection and ranging), GPS, cameras, etc. Since real-world driving environments involve diverse factors affecting autonomous driving—such as vehicles and traffic structures within the road area and buildings in the off-road area—a vast amount of testing is required to secure autonomous driving capabilities without human intervention. Meanwhile, as there are limitations to testing autonomous driving in actual driving environments, there are increasing attempts to test autonomous driving by constructing virtual environments that correspond to actual driving environments. However, current virtual environments for autonomous driving face the problem of requiring significant time and cost, such as humans directly refining and mapping data and performing 3D modeling. Due to these issues, there are many limitations in constructing virtual environments to test autonomous driving functions or autonomous driving software under various conditions. Therefore, there is an increasing demand for the construction of virtual environment simulations that take into account more realistic traffic conditions.
