What is a key responsibility of a TTC technician during road construction?

Answer: B — Planning work zone setups

A key responsibility of a TTC technician during road construction is planning work zone setups. This involves developing layouts and configurations that ensure safe traffic flow through construction areas while protecting both workers and drivers. The technician must consider various factors such as traffic volume, road characteristics, and the specifics of the construction activity when designing these setups. Effective planning includes determining the appropriate placement of signs, barriers, cones, and other devices that will guide drivers safely through or around the work zone. This role is vital because proper work zone planning helps minimize traffic disruptions and reduces the risk of accidents, thereby maintaining overall road safety. The other tasks listed, such as designing new road features, managing traffic lights, and enforcing local laws, fall outside the primary responsibilities of a TTC technician, who focuses specifically on traffic control measures related to construction activities.
