The NC of the assessment standard cloud
| Risk level | Score interval | NC | Risk description |
|---|---|---|---|
| I High Risk | [0.691, 1] | (1,0.103,0.0131) | The CTC system has basically lost all its functions and is extremely prone to major accidents and casualties |
| II Slightly High Risk | [0.499,0.883] | (0.691,0.064,0.0081) | The CTC system risk has reached a critical level, and certain improvement measures must be implemented for the risk |
| III Medium Risk | [0.407,0.593] | (0.500,0.031,0.0050) | The CTC system has the risk of reduced system performance and reduced transportation efficiency |
| IV Slightly Low Risk | [0.117,0.501] | (0.309,0.064,0.0081) | The CTC system operates well, risks in the system can be dealt with in a timely manner, and the main functions of the system can be realized |
