The invention discloses a time average speed and space average speed test method based on space-time fitting, and the method comprises the following steps: S1, data collection: collecting basic data of road traffic; S2, speed calculation: calculating the average speed by using the data acquired in the S1; S3, T inspection: the T inspection aims to inspect whether the average speeds obtained at different measurement space intervals and measurement time intervals have significant differences or not; S4, checking of result data of the time average speed and the space average speed according to the T checking result. The influence of different time measurement intervals and space measurement intervals on the average speed data is fully considered during data inspection; and a hypothesis testing method is utilized to scientifically and reasonably test the accuracy of the average speed data result.
