Hello SUMO community,
It’s been a while since I last used SUMO, so I may have forgotten some of the functions. I’m using TraCI to evaluate the impact of a lane changing vehicle over the users on the target lane. During initial tests I noticed that after the maneuver is completed, the distance between the vehicles involved (behind and in front of the one that changed lanes) doesn’t change up until the end of the simulation (straight road with two lanes). This led me to do a few tests involving TraCI. Having the same road, but with all of the vehicles on the same lane, I redefined the maximum speed for the edge every certain amount of time with the objective to find if their respective gaps varies with the traveling speed. As you can see in the charts, the vehicles respond and slowly adjust their top speed, but the distance they keep between them remains the same up until 60m/s where it widens. I may be doing something wrong, but is there a way for the vehicles to surpass the edge’s max speed for them to close the gap, adopting a sort of “rubber band” behavior? Attached you will find the files requited for the simulation (start with start_sim_VG.py) and the graphs I used. The changes in speed are indicated with the “*” following: · 20m/s when 20s<=time<40s · 30m/s when 40s<=time<80s · 40m/s when 80s<=time<120s · 50m/s when 120s<=time<160s · 60m/s when 160s<=time<200s Thank you beforehand and I hope you have a pleasant week Regards Alex
