Evaluating pedestrian areas with area measurements

You can define or generate area measurements that record data of pedestrian areas with sections. You can display and store result attributes in evaluations and lists. To allow an area measurement to record data, the following conditions must be satisfied:

At least one section must be defined in the network (Modeling sections). If sections are placed on top of pedestrian areas, they can record pedestrian area data.
At least one area measurement must be defined or generated and assigned to at least one section (Defining an area measurement in lists), (Generating area measurements in lists).
At least one pedestrian input and one pedestrian route must be defined in the pedestrian area (Modeling pedestrian inputs), (Modeling routing decisions and routes for pedestrians).

On a ramp, you can collect data from an area measurement with a section. To do so, in the Additional Level ( AddLvl ) attribute of the section, you must select the level leading to the ramp (Attributes of sections).

by default, the data for all pedestrian classes is entered together. You can also show the data for certain pedestrian classes separately in the evaluation (Configuring evaluations of the result attributes for lists).

Saving results of area measurements

You can save the following data and data formats:

Output	ASCII file	MDB table	Attribute file from attribute list

Output file of pedestrian area result

Structure of output file:

Element	Description
File title
File	Path and name of network file
Comment	Comment on simulation
Date	Time of evaluation
PTV Vissim	Version number, service pack number, build number
List	List of evaluated areas
Column names	Column headers and units
Data block	Data block with measurement data

Column	Meaning
MeasurementAreaNo	Number of section
tEnter	Time pedestrian entered the section [simulation second]
tLeave	Time pedestrian left the section [simulation second]
PedNo	Pedestrian number
PedType	Pedestrian type
DwellTime	Dwell time [s] pedestrians spent in section
vDes	Desired speed in the currently selected unit for the speed: average, minimum and maximum
v	Speed in the currently selected unit for the speed: average, minimum and maximum
DevSpeed	Deviation of pedestrian speed in the currently selected unit for the speed
Density	Pedestrian density in the sections [ped/m²] or [ped/ft²], depending on the unit set for short distances
AvgXOri	Average of x values of orientation vector
AvgYOri	Average of y values of orientation vector
WorldX WorldY WorldZ	World coordinate X World coordinate Y World coordinate Z
TimeGain	Time gain [s]: Total time gain is determined based on the delay time. The total time gain is determined only if the pedestrian is faster than desired.
TimeDelay	Time delay [s]: Total time delay is determined from the "time lost" per time step. This is determined from the difference between actual speed and desired speed if the pedestrian is slower than desired. Delays through using a detour are not taken into account in the delay.
Dist	Distance traveled so far in the sections, in the current unit set for short distances
DistNetwork	Total distance traveled so far in the network in currently selected unit for short distances
