Roadblock: Is it an Effective Tool Against a Car Bomb?

This article serves as a short preview to the history of roadblocks (road obstacles), and also as an outlook to modern and future technologies, and challenges they face in this particular field of science. At this moment, it is a real problem to stop the car immediately (if possible), before it causes damages, or threats any civil or military objects. It does not necessarily have to be only an accident, it can be a terrorist attack, which can cause enormous collateral damage and also life losses. The contemporary problem is not only the combat with fire explosive systems, but it is also important to focus on avoiding damaging of important devices, road objects or spots called “soft targets”. All this combined presents the essential challenge for roadblocks development.
