Which of the following technologies is NOT commonly used for evidence collection in traffic incident management?

In the context of traffic incident management, technologies used for evidence collection play crucial roles in documenting incidents, assessing situations, and informing response strategies.

GPS, drones, and surveying are all effective tools for gathering critical data and evidence. GPS technology is integral for accurately determining the location and movement of vehicles during incidents. Drones provide aerial perspectives that can capture images, video, and details that may be overlooked from ground level, aiding in comprehensive documentation of the scene. Surveying involves measuring and mapping sites to gather quantitative data about the surroundings and the incident itself.

On the other hand, while radio communication is essential for coordinating responses and relaying information among responders, it does not directly contribute to the collection of evidence. Instead, it facilitates communication and operational coordination rather than gathering tangible data or visual documentation. Thus, radio communication stands out as the technology that does not align with the evidence collection objective in the traffic incident management framework.
