How to market a new invention for use worldwide that is a need and a safety related device?

Question

The idea is already in a patent pending status. The device would need to be installed along the highways worldwide.

Answer 1

Based on your brief description, this sounds like a technology that would not be purchased by the general public or by typical industrial customers. It sounds like your market would be the organizations responsible for highway safety. The Federal, State and Municipal governments are responsible for design, construction, maintenance, and safety of public roads and highways. I suggest you contact your local state department of transportation. The division responsible for safety or design or engineering may have people you could discuss your invention with. Good luck.
