One of the key issues in road and urban transportation to all managers, experts, and governments is “SAFETY”. Safety is directly associated with lives, health and properties of each country citizens. Every year great number of events related to deviated vehicles happen in roads and urban areas which cause people maims and death. Thus using guardrails will be effective to prevent vehicles from deviating roads, increasing aboard and pedestrian safety in the surrounding environment of path. It’s obvious that types of guardrails being used are very effective on reducing the damage severity. The relation between safety and sound pollution reduction is an interesting issue in various fields. Using an intelligent protection system at highway margins could be studied as a safeguard for deviated vehicles and also acting as a sound barrier. This hybrid system can reduce costs and damages to the sound barriers (observed in the crash tests) and also decrease the space being occupied. Sound pollution is a serious problem in modern machine societies and lack of attention to it might lead to more direct and indirect costs which finally return to the society. So this article attempts to study the “hybrid antideath guardrails and sound barrier system” in order to reduce sound pollution and providing safety on and around highways in urban communities.
