[sumo-user] fixing bugs in a jammed simulation

Hello all,
I was hoping to get some help from you regarding different settings in my simulation of downtown Seattle, in which some links get highly jammed and many vehicles teleport.

1- My demand file has trips in the format below:
  <trip id="1" depart="18008.0" fromTaz="5000" toTaz="5003" type="passenger" departLane="free" departSpeed="max"/>
Since od2trip command assigns departing and arriving links to each id, I did not use it. However, like the 'different-source-sink' option in od2trip, I would like to make sure that trips with same origin and destination TAZs are not only in one link.

2- There are some unusual behaviors in my simulation. I would appreciate any advise to correct them. 
for example, a) in the bottom link, vehicles are not going forward in the middle lane, and vehicles that want to turn left, ONLY turn to most left lane of the adjacent link.

and b) vehicles in the south use a hight congested road with lower priority to reach the north, instead of using the link with higher priority and more lanes. Shouldn't higher priority mean a higher probability of being used in routing?

By the way, below are some hyperparameters of my sumocfg file and defintion of passenger vehicles in my simulation:

<vType id="passenger" vClass="passenger" accel="3.2" color="yellow" decel="3.5" length="4" maxSpeed="200" lcStrategic="2000" lcSpeedGain="5" lcCooperative="1" lcSpeedGainLookahead="5" minGap="1.5" cc1="0.9" cc2="4" cc3="-8" cc4="-0.1" cc5="0.1" cc6="11.44" cc7="0.25" cc8="3.5" cc9="1.5"/>

Thank you in advance for your comments.
