Maybe limiting a race to 100 "Danger Points" (or whatever number fits) which the government can use to put on systems.  If you want to add DPs to a system and have already spend all 100 you have to decrease them from those systems to use in the new one.

Maybe make it so that the more "danger points" you allocate around, the more likely civilians are to ignore the government warnings and pick, say, a danger 3/4 route instead of sticking to a 0 danger route.  Then you could make it so that the more fighting there is with aliens/ the more commerical ships are destroyed, the less likely they are to go to danger-flagged systems even if you've spammed too many danger signs.

I feel like this would be a neat approximation of the way oversaturation of warnings can cause people to disregard them, as well as stop you from controlling the civvies to hard, but also means they get "scared straight" for a while when someone breaks the rules and gets glomped by the Things From Beyond the Jump Gate

Patrolling sounds like an interesting solution.. and could maybe also be used to keep neutral aliens out/away from specific jump points.

Agree that governments have restricted civilian traffic. However, in this case that could be abused to exactly direct civilian traffic to a desired destination bu placing every other route out of bounds. If you can come up with a mechanic to implement your suggestion on an emergency basis without the potential for full-scale abuse, then I will add something on those lines.

Well, there's two problems here. The first is that for some systems you really want to more or less indefinitely keep them from being used by civilians. Like with Jumpgate linked systems when there's [spoilers] or an NPR making a mess of it when you've got colonies at either end. It would be inconvenient to have half your civilian cargo fleet commit suicide because the danger rating lapsed but you haven't managed to clear out the threat.

That could be handled by having danger rating not reduce automatically, but only when your own warships are in the system and there is no sign of enemy contacts. So you have to be in effective control for a while before civilians would consider entering.

The other problem is that the ability to precisely define the interstellar movements of civilian ships is apparently not desired.

There's two possible solutions I see, both of which are to do with the cost of enforcing a danger rating. The first is that you add PVV/tonnage of friendly military ships to civilian routing/danger level calculations for restricted systems. The bigger the difference in distance the less civilian ships care about danger/restriction ratings, so as that difference increases you need to add more and/or bigger ships to maintain the barrier. Having to dedicate half your fleet on sitting on a system so civilians do not do something they're not supposed to do is inconvenient.

The other option is that restricting a system costs wealth to impose, and an escalating amount of wealth to keep up while cancelling a restriction causes a cooldown based on how long a system has been restricted before it can be restricted again without eating a massive wealth penalty.

It is intended to portray a reluctance by civilians to enter dangerous areas so it won't be player controlled, as that would provide too much control over civilian traffic.

Governments have denied access to civilians to (potentially) dangerous areas for a long time though. It should be possible to declare a system off limits, adding any allied PPV in system to the Danger Rating, and if possible add the PPV on the other end of a given JP as well for routing calculations.

Will we be able to manipulate it in some way like increase or degrees it.

So we can set certain systems to be of limit?
