Showing delay measurements in lists
In a delay measurement, the average delay is calculated for all observed vehicles compared to a trip without any other vehicles, signal controls or other required stops. Reversing vehicles are not taken into account.
- At least one vehicle travel time measurement on a link must be defined in the network (Defining vehicle travel time measurement).
- At least one delay measurement must be defined and at least one vehicle travel time measurement must be assigned to it (Defining delay measurement in lists).
- At least one vehicle input and one vehicle route must be defined on the link (Defining vehicle inputs), (Modeling vehicle routing decision, vehicle routes and partial vehicle routes).
All vehicles that pass the vehicle travel time measurements are recorded by delay measurement.

Note: If a vehicle is recorded by several travel time measurements, it is correspondingly often entered in the delay measurement. |
Vehicle classes are grouped together
By default, the data for all vehicle classes is entered together. You can also show the data for certain vehicle classes separately in the evaluation (Configuring evaluations of the result attributes for lists).

Result of evaluation of delay measurements
A delay measurement may include the following attribute values:
| Column | Description |
|---|---|
|
SimRun |
Simulation run: Number of simulation run |

TimeInt |
Time Interval: Duration of the evaluation intervals during which the data is aggregated |
|
DelayMeasurement |
Delay measurement: Number and name of delay measurement |
|
StopDelay |
Average stopped delay per vehicle in seconds without stops at PT stops and in parking lots |
|
VehDelay |
Vehicle delay: Average delay of all vehicles The delay of a vehicle in leaving a travel time measurement is obtained by subtracting the theoretical (ideal) travel time from the actual travel time. Negative delay cannot occur. The theoretical travel time is the travel time which could be achieved if there were no other vehicles and/or no signal controls or other reasons for stops. Delay does not account for deceleration in reduced speed areas, negative delay cannot occur (Using reduced speed areas to modify desired speed). To calculate the delay caused by a desired speed decision, Vissim calculates a theoretical speed and compares it with the current speed (Using desired speed to modify desired speed decisions). The actual travel time does not include any passenger service times of PT vehicles at stops and no parking time in real parking lots. The delay due to braking before a PT stop and/or the subsequent acceleration after a PT stop are part of the delay. |
