Re: [sumo-user] Adding Warmup time

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

An alternative is to let randomTrips generate warmup vehicles that all depart in the first few seconds (by setting -e 1 and compensating with a higher number of vehicles per hour).

It will help to set vehicle attributes departSpeed="max" and departPos="last".

Hello,

 

all vehicles entering before the specified begin time are skipped. If you want to begin the simulation with traffic, you might use the state saving/loading feature.

 

Best regards

Hello,

 

I'm trying to create a scenario using the randomTrips tool. I want to simulate a scenario such that the network is not empty at the beginning; I want some traffic to be already there when I begin the simulation (non-empty network).

what I did is:
- used randomTrips to generate some traffic (route files) for a warm up period (time from 0 to 3600), then the actual simulation should start from 3600
-in sumocfg file, I set the begin time to 3600 rather than 0

 

However the simulation starts with an empty network. Any help with that? 

 

kind regards,

Rehab
