Your model has exceptions - it's good practice to remedy those before posting.

At a junction you need to stop and resume the items - that's easily done on a conveyor - and you can coordinate a number of cars that are stopped with a process flow.

Also consider using the TaskExecuter flowitem and network nodes with a traffic controller.

Thank you! In addition, when the straight car is blocked by congestion, how to let the lateral car see the traffic jam in front and stop instead of passing the car

Using network nodes? Set the network path to non-passing.

If I use a conveyor belt, can I set it to non-passing?
