Transit Pedestrian Indication

The Transit Pedestrian Indication application provides vehicle to device communications to inform pedestrians at a station or stop about the presence of a transit vehicle. In addition, this application would inform the transit vehicle operator about the presence of pedestrians nearby and those waiting for the bus. It would help prevent collisions between transit vehicles and pedestrians.

Resource Description
Application Component Certification Requirements The requirements that define the functionality, performance and operational environment of an application component. Certification Requirements must be met in order for an application to be installed in the CVE.
Device Certification Requirements The requirements that define the functionality, performance and operational environment of a connected vehicle device. Certification Requirements must be met in order for the device to be granted the credentials necessary to operate in the Connected Vehicle Environment.
Mobile Component Development System The system used in a backoffice environment to develop and test the mobile component of the application.
Mobile Component Installation System The system that interacts with the Vehicle OBE other mobile device and installs the mobile component of the application.
Mobile Component Maintenance System The system used to configure changes and updates to the mobile component of the application. This system is capable of acquiring and reporting diagnostic information about the application's configuration and performance.
Personal Information Device The 'Personal Information Device' provides the capability for travelers to receive formatted traveler information wherever they are. Capabilities include traveler information, trip planning, and route guidance. Frequently a smart phone, the Personal Information Device provides travelers with the capability to receive route planning and other personally focused transportation services from the infrastructure in the field, at home, at work, or while en-route. Personal Information Devices may operate independently or may be linked with connected vehicle on-board equipment.
Personal Pedestrian Safety The "Personal Pedestrian Safety" application improves pedestrian safety by providing pedestrian location information to the infrastructure that can be used to avoid collisions involving pedestrians. The application may also alert the pedestrian of unsafe conditions, augmenting or extending information provided by signals and signs. The information provided and the user interface delivery mechanism (visual, audible, or haptic) can also be tailored to the needs of the user that is carrying or wearing the device that hosts the application.
Personal Trip Planning and Route Guidance "Personal Trip Planning and Route Guidance" provides a personalized trip plan to the traveler. The trip plan is calculated based on preferences and constraints supplied by the traveler and provided to the traveler for confirmation. Coordination may continue during the trip so that the route plan can be modified to account for new information. Many equipment configurations are possible including systems that provide a basic trip plan to the traveler as well as more sophisticated systems that can provide transition by transition guidance to the traveler along a multi-modal route with transfers. Devices represented by this application object include desktop computers at home, work, or at major trip generation sites, plus personal devices such as tablets and smart phones.
PID Component Development System The system used in a backoffice environment to develop and test the PID component of the application.
PID Component Installation System The system used to install the PID component of a connected vehicle application.
PID Component Maintenance System The system used to configure changes and updates to the PID component of the application. This system is capable of acquiring and reporting diagnostic information about the application's configuration and performance.
Transit Vehicle The vehicle that provides the sensory, processing, storage, and communications functions necessary to support safe and efficient movement of passengers. This includes buses, paratransit vehicles, light rail vehicles, other vehicles designed to carry passengers, and supervisory vehicles.
Transit Vehicle Databus The 'Transit Vehicle Databus' represents the vehicle databus that interfaces with on-board equipment on a transit vehicle. It is a specialized and extended form of the Vehicle Databus that is subject to different vehicle databus standards and hosts a broad range of components that are unique to a transit vehicle including the farebox and associated electronics, passenger counters, and transit security systems. As a specialized form of the Vehicle Databus, it also provides access to the general-purpose sensors (e.g., radars, cameras), GPS, drive train monitoring and control systems, and vehicle safety features that support connected vehicle applications. The Transit Vehicle may represent a bus, paratransit vehicle, light rail vehicle, or other vehicle designed to carry passengers. In CVRIA, the 'Transit Vehicle Databus' is used to represent the onboard interactions between the Transit Vehicle OBE and the other systems included in a host transit vehicle.
Transit Vehicle OBE 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. In CVRIA, a separate 'Vehicle OBE' physical object supports the general V2V and V2I safety applications and other applications that apply to all vehicles, including transit vehicles. The Transit Vehicle OBE supplements these general capabilities with capabilities that are specific to transit vehicles.
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.
Transit Vehicle V2V Safety "Transit Vehicle V2V Safety" exchanges current vehicle location and motion information with other vehicles in the vicinity, uses that information to predict vehicle paths, and notifies the driver when the potential for an impending collision is detected. Information from on-board sensors (e.g., radars and image processing) are used to augment the V2V communications, if available. In addition to notifying the driver, control information can also be provided to support automated control functions that can avoid the collision. This object is similar to the "Vehicle Basic V2V Safety", but it accounts for crash scenarios that are unique to transit vehicles (e.g., Vehicle Turning Right in Front of Bus). It is also stop-aware since stop locations pose specific crash threats for transit vehicles. Finally, the detection and control algorithms, filters, and timing account for bus performance and risk profiles associated with remote vehicles that are unique to transit.
