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.

    本发明公开了基于时空拟合的时间平均速度和空间平均速度的检验方法,包括以下步骤:S1,数据采集,对道路交通的基础数据进行采集;S2,速度计算,利用S1中采集的数据进行平均速度的计算;S3,进行T检验,所述T检验旨在检验不同测量空间间隔与测量时间间隔下得出的平均速度是否存在显著差异;S4,根据T检验结果对时间平均速度与空间平均速度的结果数据进行检验。在检验数据时充分考虑不同的时间测量间隔与空间测量间隔对平均速度数据的影响;而且利用假设检验方法,对平均速度数据结果准确性进行科学、合理的检验。
