Mobile Data Terminals
display short written dispatch messages. They replace voice radio communication between the driver and the dispatcher except in emergencies or other exceptional cases. MDTs serve as the communication hub between the vehicle and computers at the control center. They automatically send vehicle location, passenger counts, engine performance, mileage, and other information. Some information like passenger boardings and alighting may be sent when the passengers’ “swipe” their smart cards as they enter or depart the vehicle or when the driver pushes function keys on the MDT. The driver can use other function keys to send pre-recorded digital messages regarding vehicle and passenger status or in response to questions or prompts displayed on the MDT screen. Thus, the MDT can virtually replace note taking and written manifests. It becomes the entry point for data to perform system wide passenger accounting and vehicle peformance analysis.
Mobile Data Terminal (MDT) allows drivers to send and re
ceive messages, trigger alarms and monitor their schedule adherence. Supervisor vehicles are also equipped with mobile data terminals (notebook computers) that allow the supervisors to view a subset of the CAD/AVL displays, fill out reports, and receive emergency alarms. The MDT and the supporting communications infrastructure can offer the transit industry the opportunity to change its business in response to consumer demand. Many of the MDTs that are currently deployed use Wi-Fi network to communicate. s
