Evaluating pedestrian travel time measurements

With the evaluation of the pedestrian travel time, you record pedestrians when they are added in the start areas until they enter the associated destination areas.

Note: Pedestrian travel time measurements must be defined in the network (Defining pedestrian travel time measurement).

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).

You can save the following data and data formats:

Output	ASCII file	MDB table	Attribute file from attribute list
Aggregated data	-	-
Raw data	*.rsrP	-	-

• Show result attributes in attribute lists (Displaying result attributes in attribute lists)
• Show result attributes in result lists (Showing result attributes in result lists)
• Save result attributes to a file (Using the Direct output function to save evaluation results to files)

Result of pedestrian travel time measurements

The file with pedestrian travel times *.rsrp contains the following data:

Element	Description
File title	Name of evaluation
File	Path and name of network file
Comment	Optional comment from the simulation parameters
Date	Time of evaluation
Vissim	Version number, service pack number, build number
Attribute names	Description of evaluated data
Data block	Measurement data

Tip: You can also save an evaluation based on the pedestrian origin-destination matrix (Saving pedestrian travel time measurements from OD data to a file).

Column	Description
t	Time pedestrian entered destination area of travel time measurement [simulation second]
No.	Travel time measurement number
PedNo	Pedestrian number
PedType	Pedestrian type
Dist	Distance traveled from the start area to the destination area
TravTime	Travel time from the start area to the destination area [s]
TimeDelay	Delay [s] from the start area to the destination area: The total TimeDelay when traveling this distance results from the "lost time" per time step. This is determined from the difference between actual speed and desired speed if the pedestrian is slower than desired. Pedestrians might walk slower than desired when they have to slow down because of other pedestrians, for instance when pedestrian density increases. Delays through using a detour are not taken into account in the delay.
TimeGain	Time gain [s] from the start area to the destination area: The total TimeGain when traveling this distance is determined accordingly like the delay. The total "time gain" is determined only if the pedestrian is faster than desired. Pedestrians might walk faster than desired when they are required to do so because of other pedestrians.
DevSpeed	Difference in [km/h] between the actual speed and desired speed while walking from the start to the end of the section.
