11 Evaluation Types for Simulations of Vehicles
11.2 Delay Times
Based on travel time sections VISSIM can generate delay data for networks.
A delay segment is based on one or more travel time sections. All vehicles
that pass these travel time sections are captured by the delay segment,
independently of the vehicle classes selected in these travel time sections.
If a vehicle is detected by more than one of these travel time sections then
it will be counted multiple times in the delay segment.
Definition
A delay time measurement is defined as a combination of a single or several
travel time measurements; regardless of the selected vehicle classes, all
vehicles concerned by these travel time measurements are also regarded for
delay time measurement. As delay segments are based on travel times no
additional definitions need to be done. For definition of travel time
measurements please refer to section 11.1.
A delay time measurement determines - compared to the ideal travel time
(no other vehicles, no signal control) - the mean time delay calculated from
all vehicles observed on a single or several link sections.
Configuration
In order to get the desired output format additional information is needed.
This is to be provided within the Delay Segments window which ca be
accessed by pressing the CONFIGURATION button in EVALUATION – FILES…
once the option Delay is ticked. The following configuration data can be
defined:
● No. [active] (Travel Times): List of all defined delay segments with the
active state flag x [in brackets].
Inactive delay measurements are not regarded for evaluation.
Selected travel time measurements are shown in parentheses.
