[sumo-user] vehicle Lane changing issue

[sandesh u. <san...@in...>]

Hi users and  authors,

I have a small problem here which resulted in a big obstruction in my simulation .

I am simulating a large data set with sumo . 

To keep it simple let me put this problem this way . 

there is long motor way and there are motorway link which connects it . the motor way is 3 lanes and link is one lane . this motor way has  links connecting it and departing from it at both ends and the distance between these points (where links  connect and leave) are very far . 

 1 \  |

       |3
       | \
       |   \5

the vehicles coming from motorway_link 5 enter the motor way and leave from motorway_link 1 but the portion of the motor way i,e 3 is very long . vehicles coming from link 5 wait for long time to enter the motor way because there are vehicles coming in the motor way in the lane which joins motorway_link 1 . 

But in reality vehicles enter the motorway at any lane and later changes the lane when the lane leading to exit is free . But in the simulation vehicles wait in the link till the lane (of the motorway)which leads to exit link is free , this waiting results in a lot of congestion in my network . 

This situation is also in junctions controlled by traffic light . 

If there is any solution for this issue .. Thank you very much in advance ..
