Terms and abbreviations
This page contains relevant terms and abbreviations mostly used in this documentation.
| Term or abbreviation | Definition |
|---|---|
| Adapter | The software module of the SmartRoad hardware-software system designed to process and transform data, received from the detector for their further transmission to the system |
| Object | Traffic object identified by the detector |
| Server | A server that performs database maintenance and management and is responsible for data integrity and security, which also provides I/O operations when the client deals with information |
DB (PostgreSQL) | A database designed to store information, which is part of the SmartRoad hardware-software system. The database can be installed either on a mini-PC, in a separate traffic intensity metering point or on a shared server for the entire project. Database receives data processed by adapter from the queue RabbitMQ and stores them in a structured way. |
| Detector | Traffic detector |
| Mini-PC | A calculator on which the adapter is installed and analysis of data from detectors is carried out |
| Event Rule | Criteria for qualifying the parameters of individual objects or traffic flow as a specific event (traffic incident) |
| Picket | Distance marking point at highways |
| PNR | Commissioning works |
| PUIDD | Traffic intensity metering point |
| Real time mode | An information processing mode that ensures the interaction of the Information Processing System with external processes at a rate comparable with the speed of these processes. |
SmartRoad system | Software-hardware system for traffic flow monitoring SmartRoad |
| Event | The fact of compliance with the event detection rule |
| TS | Transport facility or vehicle |
| Trigger | A set of conditions for the event occurrence when parameters of the traffic flow change. When a trigger event occurs, the relay is actived |
| Relay | Device for closing and opening an electrical circuit |
JSON | Text-based data exchange format based on JavaScript |
| PVR (Per vehicle record) | The basic statistical unit of recording a moving object. Vehicle registration |
RabbitMQ | Software message broker based on the AMQP standard. Sends processed data from the adapter to a queue |
SQLite | Compact embedded DBMS, installed on a mini-PC |
WebSocket | Bidirectional communication protocol between the client (browser) and the server, which allows to exchange messages in real time mode |
| Browser | A computer program designed to view pages, web-documents content information via the Internet. The main browser function is to display web pages, as well as to interact with them |
Web interface (WebUI) | A web page or a collection of web pages that provides user with an interface to interact with a service or a device via HTTP protocol and a web browser. The interaction environment between a user and a program or an application running on a remote server |
| "Sorb Engineering" LLC | Сompany name |
| Pop-up window | A window that opens on the computer screen as a result of an operation. |
| Interactive map | An e-map that works in the mode of bidirectional dialog interaction between the user and the System web interface |
| Logs | Records of events and messages created by the System during its operation |
| WebUI module | Sustainable to changes part of SmartRoad hardware-software system WebUI, which is able to work autonomously or with the integration with other modules |
| WebUI section | Part of a WebUI module |
| Engineer`s ARM | Automated engineer's workstation. This is a personal computer with the SmartRoad hardware-software system installed |
| Detection area | Detector coverage area in which objects are identified |
| Configuration file | File used to configure detector or adapter quickly |
| Raw goals | Raw data received from the detector |
| Detector sensitivity | Value, which determines the dependence of the number of points for target setting (raw goals), that are necessary for the detector to identify an object in the detection zone (for example, with a detector sensitivity of 0.8, the detector will define an object by 80 points, of 1.2 by 100, of 1.7 by 180) |
| Object ID | Unique object identifier |
| IP address | A unique address that identifies a device on the internet or on the LAN |
| Resource | Program code located on the SmartRoad server at a specific URL for processing RESTfulAPI requests, which accepts the request parameters as input and returns the corresponding processed data result |
