I want established company that make turnkey solutions for car wash traffic management systems. That include signaling when to move next and when to move out to facilitate flawless traffic. Perhaps by using any number of systems such as but not limited to License plate recognition cameras automatically logging incoming cars and linking it to queue management system to track their progress. Note also to include linking the queue management system to interior cleaning cleaning system operated by systems such as but not limited to pressure sensors in cleaning bays detecting when car has left. These are the simple systems I need. So I need established Chinese companies that can adopt these systems to my two bay car wash business
