Abstract
In this study, we propose method that estimate the inflow/outflow vehicle number in the interval. We also propose traffic state estimation method by estimated the inflow/outflow vehicle number. Unlike the freeway, in the general road, the inflow/outflow in the interval affecting the main line traffic. In order to grasp the traffic state in real-time in general road, it is necessary to develop a traffic monitoring method that considering the effect of the inflow/outflow in the interval. Therefore, in this study, it was constructed a state-space model using traffic flow model based on the kinematic wave theory and probe data. This model can estimate inflow/outflow vehicle number in situations that can not be observed inflow/outflow vehicle. Result of model verification by benchmark data, we confirmed that estimated inflow vehicle number is good precision.
