NET Trans Demand Response 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 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 Security
'Transit Vehicle Security' provides security and safety functions on–board the transit vehicle. It includes surveillance and sensor systems that monitor the on–board environment, silent alarms that can be activated by transit user or vehicle operator, operator authentication, and a remote vehicle disable function. The surveillance equipment includes video (e.g. CCTV cameras), audio systems and/or event recorder systems. The sensor equipment includes threat sensors (e.g. chemical agent, toxic industrial chemical, biological, explosives, and radiological sensors) and object detection sensors (e.g. metal detectors).
