The scientific and comprehensive measurements of effectiveness (MOE) is very important to validate the traffic improvement programs for local governments and traffic engineers, such as traffic design, signal control, route guidance. Most previous studies only focused on single indexes (travel delay, speed, the number of stops, throughput, etc.) and homogenous weighted multi-indexes (delay and number of stops), which could not represent the different-level evaluation objective, such as time-consuming cost, environment cost, fuel-consuming cost. Therefore, this study investigated individual vehicle data from floating cars and buses in urban road network under internet of vehicles (IOV), and proposed a new comprehensive traffic ecological performance index (TECOPI) with considering the ecological environment by travel speed, emissions, and fuel consumption. In tests that used field intersection from the central district of Nanchang, China, the proposed TECOPI can reflect the fluctuation tendency of traffic performance under different signal timings. The sensitivity analysis showed that the TECOPI can outperform the exiting single index.
