Video: How to use View Modes to calibrate vehicle behavior in Aimsun Next

Technical Note #39

A short video by Martin Hartmann on how to use View Modes in the capacity calibration process to model bottlenecks more realistically.

 

• Use View Modes in the capacity calibration process to model bottlenecks more realistically.

 

• This highway scenario models a 3 to 2 lane reduction.

 

• For a better overview, use the Polyline and Text tools to sketch the distances upstream from the bottleneck.

 

• Next, label the upstream sections.

 

• Visualize accelerations greater or less than 1 m/s2 to identify
major accelerations upstream from the bottleneck.

 

• To visualize longitudinal behavior, right-click on View Modes and create a new mode called CALIBRATION: Merging.

 

• Add new View Styles: Acceleration (Color) and Acceleration (Attribute).

 

• For a better overview put the most important parameters in a Text box.

 

• Turn on the View Mode and study the driving behavior under various traffic flow regimes.

 

• Visualize the total number of lane changes upstream from the bottleneck.

 

• Add a section Dynamic Attribute ‘Total Number of Lane Changes’ represented by ‘Color’,

 

• Add a condition to limit the View Mode to the sections upstream of the bottleneck.

 

• Use the same technique to add ‘Color opacity’ and ‘Attribute’ View Styles to the View Mode.

 

• Switch between the statistical intervals to compare outputs.

 

• Add Real Data Sets and follow the national guidelines to validate the simulated bottleneck capacities.
