What is the preferred method of communication for the SMDT system?

The preferred method of communication for the SMDT system is text message. This method is favored because it allows for quick, clear, and concise communication, which is crucial in the fast-paced environment of transit operations. Text messages can be sent and received without the need for immediate verbal interaction, reducing the risk of miscommunication that can occur with phone calls. Additionally, text messaging provides a written record of communications that can be referred back to as needed, which is beneficial for both operators and management in maintaining accurate logs of communications. The SMDT system relies on text messages to enhance efficiency and ensure that important messages reach bus operators promptly while preventing distractions associated with other communication methods.
