Multiple connections ：the vehicle only selects the outermost lane

[xianyang94]

Hi! I am trying to set up an entrance lane to connect multiple exit lanes. The connection form of lanes in SUMO is shown in the following figure.Lane 04_1 can be connected to Lane 14_0、14_1 and 14_2.

When vehicles are loaded into the above road network, they always choose the outermost lane 14_0, which is not consistent with the real vehicle driving behavior. The routes chosen by all vehicle are shown in the following figure.

In real traffic scenarios, vehicles can randomly select any downstream lane. What are the methods to achieve vehicle accessibility for the above connection methods14_0, 14_1 and 14_2, instead of just selecting lane 14_0. Alternatively, can i set the probability that the vehicle chooses to arrive downstream?

You can reproduce the connection problem by runing the test_demo.sumocfg script in the zip file uploaded below.

Thank you in advance! SUMO-version:1.16.0 operating system: Windows 10

You can influence lane choice through:

• lane change model configuration
• waypoints (vehicles must pass on a certain lane at a given speed)
• arrival lane (vehicle definition)

If some vehicles turn left after passing the presented junction, it may be beneficial to increase the lcStrategic value of the lane change model. If the network ends shortly right of the intersection, you can define arrival lanes for sets of vehicles.

I get the some problem like you, can you solve this problem?

the latest development version provides a new model parameter to configure the lane choice. See #15579
