Typical environment inspection practices are manual operations that rely heavily on

Problem 1: The visual database is not necessarily the same as that used for simulation calculations. Thus, a visual inspection may not even focus on appropriate data. Ex: Road centerlines are not visible on visual databases.
“Solution” to problem 1: Simulate use of “all” of the data, prior to an actual simulation event, by moving simulation entities repetitively across the database.
- Problems with “solution”:
  - Only a small percentage of relevant data is examined in most cases
  - Cannot be used in areas where simulation entity movement is prohibited
  - Cannot describe any problem cause
  - Only locates general areas
  - May be influenced by errors in the simulation control software
  - Does not provide any guide to appropriate corrective actions
  - May not be repeatable
  - It can also be very time consuming …...
