PROBLEM TO BE SOLVED: To provide a technique capable of suppressing increase in cost necessary for system construction, administration, maintenance management and precisely estimating the number of vehicles residing in an inflow link.SOLUTION: An inflow side image sensor 2b obtains the number of vehicles flowed into the inflow link of an intersection A. An outflow side image sensor 2a obtains the number of vehicle flowed out of the inflow link of the intersection A. The inflow side image sensor 2b obtains degree of saturation of the entrance of the inflow link of the intersection A. Then, the outflow side image sensor 2a estimates the number of vehicles residing in the inflow link of the intersection A by using the number of vehicles flowed into the inflow link of the intersection A, the number of vehicles flowed out of the inflow link of the intersection A, and the degree of saturation of the entrance of the inflow link of the intersection A.SELECTED DRAWING: Figure 1
【課題】システムの構築、運用、維持管理等にかかるコストの増加を抑え、流入リンクに滞留している車両の台数の推定が精度よく行える技術を提供する。【解決手段】流入側画像センサ2bは、交差点Aの流入リンクに流入した車両の台数を取得する。流出側画像センサ2aは、交差点Aの流入リンクから流出した車両の台数を取得する。流入側画像センサ2bは、交差点Aの流入リンクの入口の飽和度を取得する。そして、流出側画像センサ2aは、交差点Aの流入リンクに流入した車両の台数、交差点Aの流入リンクから流出した車両の台数、および交差点Aの流入リンクの入口の飽和度を用いて、交差点Aの流入リンクに滞留している車両の台数を推定する。【選択図】図1
