Hello, when you start a simulation you cannot only define flows but also individual vehicles with their positions and speed. This allows you to initialize your network with any desired traffic state. (If you only have the number of vehicles on an edge you need to make up plausible positions). You will need to write a script to transform your information table into suitable input files.
When running your simulation under control of a TraCI script you can also place vehicles on any position and with any speed you desire. Thus you could fill your simualation in the first step and then continue your simulation from there. regards, Jakob 2014/1/11 Pieter Loof <[email protected]> > While working with SUMO, so far I see that each simulation starts with an > empty road network.
