After finding a bug that I created a thread for, and not seeing a suggestion for this.
Have a procurement option to increase the size of the entry road. Since roads are not one-way, certain vehicles can go around a line of trucks/ cars in the current build. This causes traffic jams that crash the game.
An example of what I am talking about. 4 lane wide road for entry will help alleviate the traffic concerns. Increasing the width of the entry road can potentially mitigate this issue allowing vehicles that aren’t waiting or stuck to still come into the airport.
Potential other applications is adding a second entry point at a different location and creating 2 entrances/ exits.
Allowing for traffic to pass by the airport.
external businesses, if implemented could benefit from non airport related traffic. But things would need to be optimized a lot better for this to occur.
