The present paper uses microsimulation softs to identify the main problems regarding the speed humps location and proposes some improved solutions, with effects on traffic, pollution and safety. This paper also defines the notion of "speed hump", its main advantages, disadvantages and some implementation requests. The most accessible measures to increase road safety, both in economic and design terms, are the traffic calming measures, such as speed humps in different shapes and sizes, low-price solutions with sati...
