I like the roadworker incidents and think it's a neat job that makes the city more vibrant but it would be cool for the police to be involved. Most of these incidents need traffic control and this would be a good way to give police officers something regular to do as well.
So the idea is that when there's an incident, a call goes out (however it works script wise for dispatches with police) about the incident requesting a unit for traffic control and so any on-duty officer can accept the call and will need to go to the scene and use a command like /onscene for the duration of the incident (RP-wise, they would choose a position that blocks traffic). To incentivize officers to respond to this, they can get a bonus to their paycheck that we can consider akin to working an off-duty gig for road work. In Texas, if there is roadwork on a highway, it is required that licensed peace officers are used (usually off-duty officers) with their lights going on their POVs while work is on-going so it wouldn't be unrealistic.
Plus it would help keep roadworkers not only safe (slow down crazy drivers) but have them feel more involved in the city by having police officers around them.
