To provide a sensor performance evaluation system capable of evaluating in real time an accuracy assurance detection distance of an external sensor which is installed in a track transportation system.SOLUTION: A sensor performance evaluation system includes: a recording part 5 for recording an installation position of a ground installation object 1 and an installation identifier of a ground installation object 1 for a plurality of ground installation objects 1 respectively that are installed at the side of a track 9 on which a vehicle 8 of a track transportation system provided with an external sensor 3 travels; an installation object recognition part 4 which specifies an installation identifier from external sensor information containing information detected by the external sensor 3, and recognizes a ground installation object corresponding to the installation identifier by referring to the recording part 5; and a detection distance calculation part 6 for calculating a detection distance of the external sensor 3. The detection distance calculation part 6 calculates a detection distance of the external sensor 3 from a self-position of the vehicle 8 when a ground installation object 1 is recognized, and an installation position of the ground installation object 1 recognized by the installation object recognition part 4. Further, an installation identifier included in the ground installation object 1 is preferably a two-dimensional bar code.SELECTED DRAWING: Figure 1 【課題】 軌道輸送システムに搭載された外界センサの精度保証検知距離をリアルタイムに評価できるセンサ性能評価システムを提供する。【解決手段】 外界センサ３を搭載した軌道輸送システムの車両８が走行する軌道９の脇に設置されている複数の地上設置物１の各々について地上設置物１の設置位置と地上設置物１の設置識別子とを記録した記録部５と、外界センサ３が検出した情報を含む外界センサ情報から設置識別子を特定し、設置識別子に対応した地上設置物を、記録部５を参照することにより認識する設置物認識部４と、外界センサ３の検知距離を算出する検知距離算出部６と、を備え、検知距離算出部６は、地上設置物１を認識した時の車両８の自己位置と、設置物認識部４が認識した地上設置物１の設置位置と、から外界センサ３の検知距離を算出する。また、地上設置物１が有する設置識別子は二次元バーコードが好ましい。【選択図】図１
