[sumo-user] Make lane available when needed

[Manuel P. <man...@ho...>]

Hello SUMO community,


I'm trying to simulate a three lane highway, but I know for a fact that if
the traffic density is high enough, the cars will take the shoulder as a
fourth lane. Knowing the hours of peak traffic (because of the flows) is it
possible to make a four lane highway, but closing that extra lane and only
make it available until a certain time in the simulation?


I know you can do it by allowing/disallowing certain vehicle types on
certain lanes within the net file, but how can it be done when the
simulation has already started? In other words: how can I modify the net
file on the fly?  Could TraCi do this?


In the future I will use this to simulate a HOV lane, so I will be very
thankful for any suggestions.


Thank you beforehand for your help, and a happy new year!
