Abstract:
In order to solve the incompleteness of spatiotemporal data caused by the disrepair of traffic information monitoring equipment, a comprehensive diagnosis for traffic spatiotemporal data quality was carried out, which lays a solid data base on subsequent data quality recovery and application research. First, the time series characteristics of spot speed data and Boxplot criterion were used to objectively identify the problem data types. Secondly, a multi-attribute comprehensive evaluation indexes map was constructed according to the characteristics of different problem data types, then the entropy weight method(EWM)was utilized to assign information entropy weights for each evaluation indexes. The technique for order preference by similarity to ideal solution method(TOPSIS)was applied to obtain the closeness degree of spot speed data on road segments giving the closeness degree ranking as well. Finally, the spot speed data quality on regional road network was comprehensively evaluated by combining the closeness degree ranking results with the road attributes. The original bayonet traffic data of Urumqi road network for one week in 2021 was taken as an example, multiple data quality evaluation indicators were proposed by different problem data types. The EWM-TOPSIS method was verified through multi-attribute evaluation indexes map and road attribute. The results show that the problem data discrimination algorithm can accurately distinguish redundant data, missing data and abnormal data, meanwhile, the corresponding evaluation indexes are 5.66%, 10.04%, 5.04% respectively, and the average comprehensive availability value is 84.66%. The data quality for each road segment is better as a whole. The mean closeness degree of spot speed data on road segments is 0.25, and the mean quality index of spot speed data on regional road network is 0.19 evaluated by EWM-TOPSIS comprehensive evaluation method. The road attribute is also the one of key factors affecting the spot speed data quality on regional road network. The proposed method can identify the original traffic problem data types, objectively evaluate the spot speed data quality for regional road network by considering the road attributes, and provide a novel solution for traffic data quality diagnosis and future application services.1 tab, 6 figs, 27 refs.
