Final answer:
Active warning signs or markings should be used to mark the presence of a barrier and make it visible to oncoming traffic.
Step-by-step explanation:
The correct answer is option active warning signs or markings.
Active vehicle barriers, such as those used at tollbooth stations or certain security checkpoints, can pose serious risks if activated inadvertently. To mitigate the danger, it is important to mark the presence of a barrier and make it visible to oncoming traffic. This can be accomplished through the use of active warning signs or markings, which alert drivers to the barrier and help prevent accidents.
For example, tollbooth stations often have a wire stuck in the pavement before them. When a car approaches, the wire touches the vehicle, serving as a warning to the driver. This simple, inexpensive measure helps ensure that drivers are aware of the barrier ahead, reducing the likelihood of accidental activation and the potential for serious injury.
The correct answer is that active vehicle barriers should be marked with highly visible signage, bright lighting, and possibly reflective materials to ensure that they are clearly visible to oncoming traffic, and to help prevent accidental activation and potential injury. High-visibility stripes or warning signs can be very effective.
Furthermore, installing rumble strips or other tactile warning devices before the barrier can alert drivers of its presence. It's also important to have clear signals that indicate when the barrier is active or down.
In areas with frequent pedestrian traffic, such as near a campus, ensuring the visibility of active barriers is crucial for pedestrian safety, as well.
Moreover, traffic signals play an important role in managing vehicle speeds and pedestrian crossings, contributing to a reduction in the number of accidents and enhancing overall traffic safety.
Technology like cameras, transponders for toll collection, and GPS systems are part of a broader trend to improve traffic management and public safety through surveillance and data analysis.
