RTC ACCESS Paratransit Vehicles - Transit Vehicle OBE Functionality
Subsystem Description
The Transit Vehicle On–Board equipment (OBE) resides in a transit vehicle and provides the sensory, processing, storage, and communications functions necessary to support safe and efficient movement of passengers. The types of transit vehicles containing this physical object include buses, paratransit vehicles, light rail vehicles, other vehicles designed to carry passengers, and supervisory vehicles. It collects ridership levels and supports electronic fare collection. It supports a traffic signal prioritization function that communicates with the roadside physical object to improve on–schedule performance. Automated vehicle location enhances the information available to the transit operator enabling more efficient operations. On–board sensors support transit vehicle maintenance. The physical object supports on–board security and safety monitoring. This monitoring includes transit user or vehicle operator activated alarms (silent or audible), as well as surveillance and sensor equipment. The surveillance equipment includes video (e.g. CCTV cameras), audio systems and/or event recorder systems. It also furnishes travelers with real–time travel information, continuously updated schedules, transfer options, routes, and fares. A separate 'Vehicle OBE' physical object supports the general vehicle safety and driver information capabilities that apply to all vehicles, including transit vehicles. The Transit Vehicle OBE supplements these general capabilities with capabilities that are specific to transit vehicles.
Functional Object: Transit Vehicle On-Board Fare Management
'Transit Vehicle On–board Fare Management' supports fare collection using a standard fare card or other non–monetary fare medium and detects payment violations. Collected fare data are made available to the center.
Functional Object: Transit Vehicle On-Board Information Services
'Transit Vehicle On–board Information Services' furnishes en–route transit users with real–time travel–related information on–board a transit vehicle. Current information that can be provided to transit users includes transit routes, schedules, transfer options, fares, real–time schedule adherence, current incidents, weather conditions, non–motorized transportation services, and special events are provided. In addition to tailored information for individual transit users, it also supports general annunciation and/or display of general schedule information, imminent arrival information, and other information of general interest to transit users.
Functional Object: Transit Vehicle On-Board Maintenance
'Transit Vehicle On–Board Maintenance' collects and processes transit vehicle maintenance data on–board the vehicle, including mileage and vehicle operating conditions. This maintenance information is provided to the management center and used to schedule future vehicle maintenance and repair.
Functional Object: Transit Vehicle On-Board Paratransit Operations
'Transit Vehicle On–board Paratransit Operations' forwards paratransit and flexible–route dispatch requests to the operator and forwards acknowledgements to the center. It coordinates with, and assists the operator in managing multi–stop runs associated with demand responsive transit services including paratransit. It collects transit vehicle passenger data and makes it available to the center.
Functional Object: Transit Vehicle On-Board Trip Monitoring
'Transit Vehicle On–Board Trip Monitoring' tracks vehicle location, monitors fuel usage, collects operational status (doors opened/closed, running times, etc.) and sends the collected, time stamped data to the Transit Management Center.
Functional Object: Transit Vehicle Schedule Management
'Transit Vehicle Schedule Management' monitors schedule performance and identifies corrective actions when a deviation is detected. It provides two–way communication between the transit vehicle and center, enabling the center to communicate with the vehicle operator and monitor on–board systems.
