ATMS is here! The Advanced Transportation Management System (ATMS) is installed on the entire Metro Bus fleet and the fleet is becoming one of the smartest in the world. A major part of ATMS is the new radio system, but ATMS is also a new dispatch system, a new vehicle location system, a new passenger counting system, an Americans with Disabilities Act (ADA)-compliant annunciator system, an improved video camera system - and more. Learn more about ATMS through the overview below. ATMS Overview Metro’s ATMS is the largest and most feature-packed system of its type in the world. Known in the industry as Smart Bus technology, ATMS is a high-tech system composed of hardware and software communication and fleet management tools. At its core are brand new transit radio and computer-assisted dispatch systems. Also included in Metro’s ATMS are vehicle location, passenger counting, voice annunciation, and visual monitoring systems. ATMS is installed on all Metro Buses, with various radio antenna sites throughout the Metro service area. On-vehicle ATMS systems and a Vehicle Area Network (VAN) are used to link all the various ATMS pieces together. This works much the same way that a computer network operates in a business office, connecting desktop computers to each other and to printers, scanners, fax machines and other equipment. The new ATMS Transit Radio System (TRS) uses three types of radios: data, voice, and Wide Area Network (WAN). The data radio provides real-time fleet management and text-based radio messages. The voice radio is used for all voice communication, such as when an operator uses the bus radio. The WAN radio is used to transfer data files and system updates. Computer Assisted Dispatch (CAD) is a collection of hardware and software that turns the TRS into a powerful multi-featured communication and management tool. The Automatic Vehicle Location (AVL) system relies on Global Positioning Satellites (GPS) to provide the location of every ATMS-equipped vehicle. The AVL system is used for immediate location of a bus, for example: during an emergency. Automatic Passenger Counting (APC) is used to quantitatively monitor Metro Bus service and to provide information used for planning future services. Sensors mounted in bus doorways count passengers getting on and off. Location and time information from the AVL system is added. At the end of the day, the WAN is used to transfer the data from the bus to Metro’s central computer system for processing and reporting. Automatic Voice Annuciation (AVA), part of Phase II and soon to be implemented, will provide next bus stop announcements for all Metro Bus passengers. It is fully ADA-compliant, using both audio (public address system) and visual (electronic message sign) announcements. The AVA system uses information from the AVL system and the AVA database to determine when to make the announcements and what announcement will be made. Video Surveillance System (VSS), also part of the Phase II implementation, uses video cameras to monitor events on Metro Buses to enhance passenger and employee safety.
