Hello,
hello, by default vehicles start with speed 0 at position 0 in the
rightmost lane of a random network edge (you can change all these by
setting vehicle attributes). If that edge is a motorway, it may indeed be
unrealistic. In an urban scenario, this could simply be their previous
parking spot.
You have several options:
- let vehicles start with high speed (see option --trip-paramters at
http://sumo-sim.org/wiki/Tools/Trip#randomTrips.py)
- use a high --fringe-factor to let vehicles only start at on-ramps or at
the border of your network

regards,
Jakob
