Evaluating vehicle travel time measurements
A vehicle travel time measurement consists of a From Section and a To Section. The mean travel time from traversing the From Section up to traversing the To Section, including the waiting time and/or holding time, is calculated as well as the distance traveled between the start section and destination section. Reversing vehicles are not taken into account.
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).
You can also evaluate delays with travel time measurements (Showing delay measurements in lists).

|
Note: Vehicle travel time measurements must be defined in the network (Defining vehicle travel time measurement). |

- Show result attributes in result lists (Showing result attributes in result lists)
- Save result attributes to files or databases (Configuring evaluations for direct output)
For calculation of result attributes set the marker for aggregation by time of passing
1. From the Evaluation menu, choose > Configuration > Result Attributes tab.
2. In the Vehicle travel times row, select the option Collect data.
3. If desired, change the time and interval (Configuring evaluations of the result attributes for lists).
4. Click the More button.
The Vehicle travel times window opens.
5. Select the time at which the travel time measurement results are aggregated to time intervals if the two times at which the vehicle crosses the start section or the destination section are in different time intervals.
Result of evaluation of travel time measurements
The results list Vehicle Travel Time Results contains the following attributes:
| Result attribute Long name |
Short name |
Description |
|---|---|---|
| Vehicles | Vehs | Number of vehicles recorded |
| Vehicle travel time measurement | VehTravTmMeas | Name of vehicle travel time measurement |
| Travel time | TravTm | Average travel time [s] of vehicles in the network |
| Simulation run | SimRun | Number of simulation run |
| Distance traveled | Dist | Average distance traveled [m] between the start section and destination section of travel time measurement. If there is only one path leading from the start section to the destination section, its value corresponds to attribute Distance value of travel time measurement (Attributes of vehicle travel time measurement). Distance traveled in reverse is not taken into account. |
| Time interval | TimeInt | Duration of the evaluation intervals in which the data is aggregated |
