- Abstract:
- The goal of using speed humps is to reduce the velocity of cars to allowable value. Reducing the speed more than necessary before arriving at the hump, causes losing kinetic energy whose compensation needs consuming more fuel. In fact, the total fuel consumption of vehicles is noticeable and it expresses the need for allowable speed definition to prevent wasting fuel. In this project, using different methods in engineering design and by defining allowable speed, an intelligent speed hump is designed and selected from different patterns which may remain protuberant or become like the road surface in level. The parts considered for this hump are selected simple to lower the cost of construction process. Simplifying the structure of the hump not only does not weaken the structure but also will help to use simple and commercially available profiles to make a strong mechanism. The strong structure could last in contact with severe impulses and also, it can result in the stresses to be spread through the hump. There is a locking part in the structure of mechanism which is controlled by an electrical circuit. The circuit responds to the pulse received from an electrical key installed in road surface before the hump. The designed speed hump was tested and by putting the electrical key in different distances, different results were obtained. These results were evaluated and finally the best distance of the key from the hump was obtained
