Vehicle Characteristics --> Transit Vehicle OBE:
vehicle characteristics

Definitions

vehicle characteristics (Information Flow): The physical or visible characteristics of individual vehicles that can be used to detect, classify, and monitor vehicles and imaged to uniquely identify vehicles and characterize their performance (e.g., speed, occupants, emissions).

Vehicle Characteristics (Source Physical Object): 'Vehicle Characteristics' represents the external view of individual vehicles of any class from cars and light trucks up to large commercial vehicles and down to micromobility vehicles (MMVs). It includes vehicle physical characteristics such as height, width, length, weight, and other properties (e.g., magnetic properties, number of axles, occupants, emissions) of individual vehicles that can be sensed and measured or classified. This physical object represents the physical properties of vehicles that can be sensed by vehicle-based or infrastructure-based sensors to support vehicle automation and traffic sensor systems. The analog properties provided by this terminator represent the sensor inputs that are used to detect and assess vehicle(s) within the sensor's range to support safe AV operation and/or responsive and safe traffic management.

Transit Vehicle OBE (Destination Physical Object): 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.
