Most, if not all of APRS is done via Amateur Radio. However, there are some commercial systems that do what you want and the few that I have seen are in police cars. You might check with some of the police departments in your area to see if they could give you a lead that way. 

Do you already have a licensed frequency you can use?  That will help a bunch.
