Final answer:
Traffic technicians are responsible for evaluating info, communicating with team members, updating their knowledge, and gathering info. Selling or influencing others can also be part of an engineer's role, though it is not the core task of traffic technicians.
Step-by-step explanation:
Traffic technicians undertake a variety of common work activities in order to improve commuting issues faced by the engineering team, often looking into aspects such as traffic congestion, accidents, and pollution. Some of the tasks they perform include:
Evaluating information to determine compliance with standards (A)
Communicating with supervisors, peers, or subordinates (D)
Updating and using relevant knowledge (E)
Getting information (F)
While not typically associated with traffic technicians, selling or influencing others (B) can be a part of an engineer's responsibilities, particularly when making presentations or interacting with clients. The repairing and maintaining mechanical equipment (C), though it can be related to their work, is often more specific to the hands-on maintenance of traffic-related equipment, which may only sometimes be part of their duties. Engineers utilize their communication skills broadly, from applying for jobs to making presentations and interacting with customers.
