Abstract
<p>In this study, we propose a method for estimating the traffic flow rate at an accident location using a state space model. In traffic control, it is important to understand the traffic flow rate at the accident location. On the Metropolitan Expressway, vehicle detectors are densely arranged, and the traffic flow rate at the accident location can be measured. However, there is a problem in terms of cost for maintain all vehicle detectors. On the other hand, a large amount of probe data has been measured, and a method of using it has been sought. In the future, it is desirable to reduce the number of current vehicle detectors using probe data and rationalize them. However, the probe data cannot measure the traffic volume. Therefore, in this study, we construct a state space model using vehicle detectors, probe data and variational theory, and try to estimate the traffic flow rate. As a result of the verification, the traffic flow rate at an accident location was accurately estimated.</p>
