  Evaluation of controlled airspace capacity based on the controllers’ workload is the most wildly used theoretical evaluation method of controlled airspace capacity currently in China. This method uses the aircraft sorties to be the only metric. It identifies some quantitative relationship between the metric of aircraft sorties and controllers’ workload. The method then figures out the controllers’ workload and evaluates the capacity value limited by the controllers’ workload ability in the controlled airspace according to the DORATASK method. But in actual operation, aircraft sorties is not the only Influencing factor of controllers’ workload. Therefore, a new evaluation method of controllers’ workload based on the metric of traffic complexity is proposed. This new method uses a group of multidimensional metric of air traffic complexity to research and solve the problem of evaluating the controllers’ workload, Instead of using a traditional single traffic measurement- aircraft sorties. The method is applied in the capacity evaluation project of control sector 02 in Shanghai. The evaluation results are recognized by the front-line ATC experts. Meanwhile they also verify the feasibility and correctness of the method applying to the airspace capacity evaluation.

  The controller’s performance directly affects the safety and the efficiency of ATC at any moment. It’s a reasonable and feasible method to get the sorting results of the different planning schemes through the assessment of the sector controller workload. However, all planning schemes can not be implemented until it passed the practice test for the first-line controller. This study brings forward integrated evaluation of the controller’s workload based on improved integrated evaluation model which combines the quantitative and the qualitative analysis. The condition set is constructed and the correlation value of the sample with practical data is calculated. The correlation function and the weight function are built. By the calculated value, the category is selected. The sample in the terminal control area of Shanghai confirms that the method is feasible.
