Yes, it's possible to adjust the road network in PTV VISSIM during the simulation using the COM interface. Through COM (Component Object Model) development, you can dynamically modify the properties of the road network, such as the number of lanes or link lengths, during the simulation process.

Here is a general outline of the steps you might take:

Remember to refer to the VISSIM COM interface documentation for details on available commands and properties. The ability to dynamically adjust the road network parameters can enhance the flexibility of your simulation and allow for more realistic scenarios.

In Azerbaijan, in 16 regions, a study was conducted to improve Mobility using simulation on PTV VISSIM. Using this program, you can organize flexible management of traffic flows.
