Transport Rules can be crucial for managing the flow of resources around your colony. Rules can be applied at the following locations:

Road Posts

If you apply a rule to a road it will affect all resources arriving from all connected roads.

Harbours & Train Stations

For transport buildings rules can be applied to resources that are imported (unloaded from boats/trains), exported (loaded onto boats/trains), or both.

Boats & Trains

For each stop that a boat or train makes, rules can be applied to affect which resources are loaded onto the boat or train.

Rule Types

There are different types of rules that can be applied:

• Blacklist - If you blacklist a resource it will not be able to pass through under any circumstance.
• Blacklist Except Storage - This option means accept the resource if it's going to a storage yard.
• Whitelist - means only the selected resources will be able to pass through.
• Whitelist Storage Only - This option means only whitelisted resources will be able to pass through and only if they're going to a storage yard.

Note: A ruleset cannot hold both blacklist and whitelist as they would conflict, so once you have set a rule of one type, the other type will be disabled.

Examples

Here is a simple, common example of using resource rules at a road post to ensure that food and water are only delivered to the nearby houses. This not only maintains regular supply to these houses but it also helps clears your roads clear.
