[sumo-user] Route override after dispatchTaxi()

[Jay Patel <jayyyyp2416@xxxxxxxxx>]

I am using the dispatchTaxi() and trying to re-route the taxi route after onboarding the passenger, I had specified the route it should follow, but I am getting the error of "no connection edge between B0B1 and B0B1". I am attaching my code with this email

I don't want to use the default route set by traci dispatchTaxi(). How can I safely override the route after dispatchTaxi()? but I want to use my custom route after onboarding the passenger. Plz help me with this issue. 

Thanks, 

Jay
