An Estimation Method for Deploying Condition of Sensors in Cooperative Observation of Road Traffic

The digital twin is currently being introduced in a variety of fields. The construction of a digital twin of road traffic will contribute to predicting and simulating traffic flow for optimizing transport systems and reducing traffic congestion. In order to construct a digital twin in road, it is necessary to identify the effective deployment conditions of several sensors. Therefore, in this paper, an estimation method of sensor deployment conditions for accurate observation of road space is proposed. The proposed method estimates the optimal number and location of sensors based on simulation by virtual reality. Experiment is conducted to confirm whether the proposed method can estimate the optimal number and location of sensors.
