Potential Obstacles --> Transit Vehicle OBE:
physical presence

Definitions

physical presence (Information Flow): Detection of an obstacle. Obstacle could include animals, incident management and construction elements such as cones, barrels and barriers, internal structures such as pillars and poles, rocks in roadway, etc.

Potential Obstacles (Source Physical Object): 'Potential Obstacles' represents any object that possesses the potential of being sensed and struck and thus also possesses physical attributes. Potential Obstacles include roadside obstructions, debris, animals, infrastructure elements (barrels, cones, barriers, etc.) or any other element that is in a potential path of the vehicle. Note that roadside objects and pieces of equipment that can become obstacles in a vehicle's path can include materials, coatings, or labels (e.g., barcodes) that will improve the performance of the vehicle-based sensors that must detect and avoid these obstacles. See also 'Vulnerable Road Users' that more specifically represents the physical properties of shared users of the roadway that must also be detected.

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.
