Hi there. I’m encountering an issue with the CitySample project, where I’m setting up a few camera feeds to simulate a smooth traffic flow scenario on the freeway in CitySample. However, after some time, about 20 or 30 minutes, the freeway traffic stalls due to traffic jams and crashes. Are there any specific parameters or settings I need to adjust to prevent these issues altogether?
Here are some of the options I’ve tried:
-
Restrict Freeway Long Vehicles (Trucks and Buses) to the right-most lane only.
-
Lower Freeway Speed Limit from 60mph to 35mph
-
Reduce Spawn Count/Density from 17000 to 10000 or less
-
Plus, adjusting these Mass Avoidance Settings under Project Settings:
- IdealTimeToNextVehicleRange = 1.5 – 2.0 (Default) → 2.5 - 3.0
- ObstacleAvoidanceBrakingTimeRange = 1.5 – 3.0 (Default) → 3.0 - 4.5
The Unreal Engine version here is 5.6.1.
