For ultimate cohesion/immersion with your background non-law enforcement vehicles, I scrapped and cobbled together this set.
Transit Police liveries are the only ones I did NOT put together myself. Those are from Chief1234, and I highly recommend their CVPI file (attached below) with their livery. I just adapted it to fit other vehicles. 
The bus liveries are enhanced (from the ground up) vanilla Transit liveries by me. I added ads to the sides and rear, and designed the Rapid Line blue liveries to add some variety to the buses. 
I don't have a link to the F150's used, and the liveries are transparent. I used the orange color base, or 38 in carvariations to make it always spawn same color. Supervisor livery is white or 111 for carvariations.
The old RTS bus already had a similar livery, I linked that as well despite not attaching any liveries for it. They're included with the original and it's quite good.
