Simulation/Variable Speed Signs

One of the trigger objects that may be specified within an additional-file allows the simulation of variable speed signs. The syntax for such an object is: " lanes="[ ]*" file=""/>.

A file name must be supplied, called  within the schema above. This file must contain the information about when a certain speed shall be set onto the lane. This file has the following format: " speed=""/> " speed=""/>

... further entries ...

" speed=""/>

Each step is a combination of the time the next new speed shall be set and the speed to set itself.

A small example for usage of vss' may be found in the SUMO directory under "examples/sumo/variable_speed_signs".
