This paper focuses on the operation changes of taxi systems with the wide-usage of e-hailing apps using the calculated taxi OD pairs data of Shanghai in 2012 and 2015 and applied an evaluation process to analyze the possible impacts from three dimensions, namely, taxi system supply, operation efficiency, and service coverage. The results reveal that the e-hailing apps have partly improved the taxi operation. On the one hand, the supply of later taxi systems has experienced an obvious drop; however, on the other hand, the existing taxi system has overall higher efficiency owing to the decreased percentage of vacant trips. The comparison of taxi trips demonstrates that the taxi system can better satisfy larger-scale and longer-time service demands than before, especially in some low-density areas and during the non-peak hours. The findings provide another perspective for decision-makers to comprehensively understand and management the taxi system or urban transport after e-hailing service.
