In order to reduce a driver-dependent variation in test result by enhancing the reproducibility of driving indices at the end of a test, a vehicle running test system includes a vehicle speed pattern display apparatus adapted to display a prescribed speed pattern and current vehicle speed on a graph with one axis as vehicle speed and the other axis as time or running distance is adapted to, while a vehicle is being driven, separately from the vehicle speed, display information based on driving indices indicating a driving state of the vehicle, simultaneously with the graph.
