Analyses: metrics, objects, and outputs
This topic lists all the possible metrics and outputs for each of the Analysis Objects (including 'Entire model', which does not require an Analysis Object). Once you have decided on the metric or metrics you wish to apply, you can work out which, and how many, Analysis Objects to place.
Crowd Metrics
Click the following metrics to reveal a drop-down list of the Analysis Objects they require and the types of graph which can be generated from the metrics.
| Metric | Analysis object | Graphs available |
|---|---|---|
| Count Inside | Analysis Zone | Instantaneous, Average |
| Egress | Analysis Zone | Instantaneous, Cumulative, Average |
| Ingress | Analysis Zone | Instantaneous, Cumulative, Average |
| Space Density | Analysis Zone | Instantaneous, Average |
| Generalised Journey Time (GJT) | Analysis Zone | Instantaneous, Average |
| Entity Count/Flow Rate | Analysis Line or Lines
Also, automated flow-rate analyses for Stair and Escalator objects. |
Instantaneous, Cumulative, Average |
| Normalised Flow Rate | Analysis Line | Instantaneous, Average |
Entity Metrics
Click the following metrics to reveal a drop-down list of the Analysis Objects they require and the types of graph which can be generated from the metrics.
| Metric | Analysis object | Graphs available |

| Discomfort | Analysis Zone | Instantaneous, Average, Advanced Average, Distribution (histogram), Distribution over time (%), Distribution over time (values) |
| Dissatisfaction | Analysis Zone | Instantaneous, Average, Advanced Average, Distribution (histogram), Distribution over time (%), Distribution over time (values) |
| Distance | Analysis Zone, Analysis Line or Lines | Instantaneous, Average, Advanced Average, Distribution (histogram), Distribution over time (%), Distribution over time (values) |
| Entity Density | Analysis Zone | Instantaneous, Average, Advanced Average, Distribution (histogram), Distribution over time (%), Distribution over time (values) |
| Frustration | Analysis Zone | Instantaneous, Average, Advanced Average, Distribution (histogram), Distribution over time (%), Distribution over time (values) |
| Inconvenience | Analysis Zone | Instantaneous, Average, Advanced Average, Distribution (histogram), Distribution over time (%), Distribution over time (values) |
| Journey Time | Analysis Zone, Analysis Line or Lines | Instantaneous, Average, Advanced Average, Distribution (histogram), Distribution over time (%), Distribution over time (values) |
| Speed | Analysis Zone, Analysis Line | Instantaneous, Average, Advanced Average, Distribution (histogram), Distribution over time (%), Distribution over time (values) |
Count Remaining
If you are analysing a zone or the Entire model, the tab 'Count Remaining' is available. Here you can instruct your analysis to generate a graph which displays the number of Entities remaining in the zone or model over time. To do so, check the box labelled 'Enable the Count Remaining statistic'.
If you are analysing the Entire model, all origin objects will be considered. If you are analysing a zone, you will be able to select a specific origin object. See Setting up analyses.
- Journey Time replaces metrics previously known as Time Taken and Time Spent Inside.
- Inconvenience, Frustration, Discomfort and Dissatisfaction are only available on-line or if included as an option when the 'res' file was recorded.
- Category definitions in histograms are dynamically adjusted when a Colour Range is used.
- Histograms are now cumulative, not instantaneous as in earlier versions.
