Eco-Driving

The practice of driving in such a way as to minimize fuel consumption and emissions.

Eco-Lane

A dedicated lane(s) optimized for the environment similar to high-occupancy vehicle lanes; however, these lanes are optimized for the environment using connected vehicle data. These lanes would be targeted toward low-emission, high-occupancy freight, transit, and alternative-fuel vehicles (AFV). Drivers would be able to opt in to these dedicated eco-lanes to take advantage of eco-friendly applications such as eco-speed limits, eco-cooperative adaptive cruise control and connected eco-driving applications.

Electronic On-Board Recorders

A device on-board a commercial vehicle used to record driver information such as hours of service.

Element

1) a constituent part of something; 2) any thing that is one of the individual parts of which a composite entity is made up; 3) an identifiable component, process or entity of a system.
In terms of CVRIA and project specific architectures derived from CVRIA, an element is a connected vehicle system or piece of a system (e.g., device or component) named as the name used by stakeholders in a region. Elements are the basic building blocks of connected vehicle project architectures, developed using SET-IT, and are mapped to a physical object in CVRIA.

Encrypt

To convert readable data to unreadable, encrypted data using an encryption algorithm and a key. See Decrypt.

End-User

The ultimate user of a product or service, especially of a computer system, application, or network.

Engineering Object

An implementation or realization of some abstract function. It may be implemented as hardware or as software.

Enterprise Object

An organization or individual that interacts with other Enterprise Objects and/or physical objects. An Enterprise Object may be a component of another larger Enterprise Object, which may in turn be a component of a third, even larger, Enterprise Object (e.g., a Traffic Management Center Manager is a component of State DOT is a component of State Government). Enterprise Objects may participate wholly or in part in other Enterprise Objects (e.g., a Device Developer is a component of Auto Manufacturer but also participates in Standards Body).

Enterprise View

Describes the relationships between organizations and the roles those organizations play within the connected vehicle environment. This enterprise view provides the basis for understanding who the stakeholders will be and the roles these implementers could take in implementing architecture-based connected vehicle systems.

Entity

Any physical or abstract thing of interest. For example, an entity may be a computer, an organization, a piece of software or a set of functions performed by a system.

Environment

The circumstances, objects, and conditions that surround a system to be built; includes technical, political, commercial, cultural, organizational, and physical influences as well as standards and policies that govern what a system must do or how it will do it.

Event Snapshot

A snapshot generated when the connected vehicle when a sensor value exceeds a specific threshold.

Extensibility

The ability to add or modify functionality or features with little or no design changes.

Extensibility

The ability to add or modify functionality or features with little or no design changes.

External Support System

An entity that provides a service the connected vehicle system needs to support or deliver. This service is provided by the ESS because it makes more sense to manage, maintain and share the service between multiple connected vehicle systems due to overriding institutional, performance or functional constraints.
