Which of the following factors is NOT typically considered when selecting traffic barriers?

When selecting traffic barriers, the primary factors typically considered include road alignment, deflection space, and sight distance. Each of these elements plays a critical role in ensuring the safety and effectiveness of the barriers in a traffic control situation.

Road alignment is important because barriers must be placed in a way that complements the curvature and configuration of the road. This helps to ensure that the barriers provide adequate protection to vehicles while also maintaining the natural flow of traffic.

Deflection space is crucial because it refers to the amount of space needed for a barrier to absorb the impact of a vehicle without causing additional hazards. A barrier must be designed to allow for this deflection to minimize the risk of injury or damage in the event of a collision.

Sight distance is also a significant consideration, as it dictates how far ahead a driver can see and react to possible obstacles, including barriers. Adequate sight distance helps drivers make informed decisions, thereby reducing the likelihood of accidents.

In contrast, vehicle weight is not a primary factor usually examined when selecting traffic barriers. While the weight of vehicles may inform the design aspects of the barriers themselves (such as their durability and ability to withstand impact), the selection process generally focuses on the physical environment and the traffic patterns rather than the weight of individual vehicles
