Since the topography checker is extended to the other tabs, here is a place to add in your ideas / wishes on what the Scenario Checker could do:

Simulation

• ERROR: Bounds for simTimeStepLength - Suggestion: [0.01 - 1]
• WARNING: realTimeSimRatio != 0 - only if started from console (Maybe this could also be realized by visualizationEnabled = false -> then automically realTimeSimRatio is set to 0)

Model

• WARNING: OSM + optimizationType = DISCRETE AND varyStepDirection = False -> Background: Pedestrians might not be able to walk through small passages
• WARNING: loadingType "CONSTANT_RESPECT_TARGETS" and "DYNAMIC" because they are deprecated (compare: https://conwiki1.cc.private.hm.edu/confluence/display/FK07PD/VADERE+Input+Parameters)
• WARNING if the parameters deviate from the default configuration - to avoid accidental "mis-"settings
• WARNING if groupSizeDistribution of any source is different from [1.0] but AttributesCGM is not present in Model tab (no groups will be simulated)

Topography

• ERROR: No target that has absorbing = true (that means pedestrians will never leave the simulation)
• WARNING: if a list of targets is defined but one (which is not the last one) has the attribute absorbing = true -> pedestrians won't reach their final target
• WARNING: if radius != 0.2 (because at the moment all potentials are calibrated for this radius)
• ERROR: If in a source a group distribution is given where something other then groups of 1 are produced and the group submodel is not given throw an error.
• ERROR: If a pedestrian has no target (separate pedestrian)
• ERROR: If distributionParameter of the source is 0.0 - leads to Exception (Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException)
• WARNING: if the source is too small for the amount of agents spawning. Some formula to estimate the pedestrian density required here, e.g. sourceArea / spawnNumberInSeconds < alpha => warning!
• WARNING: if footStepsToStore is zero (position interpolation and computing speed does not work then properly)
• WARNING: if lineCrossProcessor is within obstacle (flow will not be calculated correctly!)
  -> maybe also, LineCrossProcessor attribute Line line can be defined as Measurement Area
• ERROR: agents might stop suddenly in front of non-absorbing targets if agent's minStepLength and target's deletionDistance are in conflict. Therefore, check minStepLength < deletionDistance or minStepLength + eps < deletionDistance. See #140.
• ERROR: if area of obstacle == 0

TargetChangers

• NO WARNING: If a TargetChanger is present, some targets might be used only by it. In this case, a warning is currently displayed that the target is unused.
• WARNING: If a TargetChangeris present but useMinimumStepLength is ´´true``. Recommend to set to ´´false´´.

Free-flow speed

• ERROR: In attributesPedestrians: When the speedDistributionMean is set larger or smaller than the minimumSpeed and maximumSpeed (NOTE: same as in Topography checker for single placed peds)
• ERROR: Negative (maybe even non-positive?) minimumSpeed && The maximumSpeed set larger than 12 m/s (12.4 m/s is the world record by Usain Bolt) (NOTE: same as in Topography checker for single placed peds)
• ERROR: minimumSpeed is larger than maximumSpeed
• WARNING: If the free-flow std is larger than the limits for minimumSpeed and maximumSpeed allow.

Data processing

• WARNING if writeSimulationData = false even though output processors are added and files are defined in which their output should be saved
• ERROR if group model is active groupId Processor must be selected
• ERROR if PedestrianPositionProcessor is set and footStepsToStore is 0. Bachground: The pedestrian position processor uses the latest foot step for interpolation, so it always needs the latest footstep and therefore a capacity of minimum 1.
