Vehicles and telemetry

Vehicle — a unit of the fleet. It reports nothing by itself: telemetry comes from the device bound to it.

Device (tracker) — a GPS receiver bound to a vehicle by a unique identifier. A vehicle can have a history of several devices; the current one determines where telemetry comes from.

Telemetry — the data stream from a device: coordinates, speed, course, signal quality.

Course — the direction of travel in degrees.

Lag — how old the most recent data is. High lag with an "online" status means a connectivity problem, not a stop.

Vehicle status — Moving, Idle, Stopped, Loading.

Trip — an unbroken stretch of movement from start to stop. The basis for distance, average speed and time-moving calculations.

Speed profile — a chart of speed along a trip's track, with maximum and average markers.

Simulation — a virtual device streaming telemetry along a route you draw. It produces real events.

The map

Layer — a group of like objects on the map: vehicles, geofences, cameras, cargo, traffic.

Basemap — the background cartographic imagery.

Layer style — the rendering settings: colour, size, labels, ring, halo, fill, border, stacking order.

Z-order — which layer draws on top of the others.

Destination — an assigned arrival point for a vehicle. A route is built to it and an arrival forecast computed.

ETA (arrival forecast) — the estimated time of arrival. Recomputed as the vehicle moves; the Forecast built … stamp records when.

Arrival radius — the area around a destination; entering it counts as having arrived.

Geofences

Geofence — a named area on the map.

Operational zone — a yard, depot or site.

Speed zone — an area with a speed limit.

Restricted zone — an area whose entry raises an alert.

Crossing — an entry or an exit. The record holds the entry time, the exit time and the duration.

Dwell — how long an object spent inside a zone.

Peak occupancy — the largest number of objects inside at the same time.

p95 — the value below which 95% of measurements fall. Sturdier than the average: it shows how the fast end of the traffic behaves without single outliers.

Cameras and recognition

Fixation — a camera's detection of a vehicle: snapshot, time, camera, recognised plate.

Detection — the detection of an object of any class (vehicle, person and so on). A fixation is a detection taken as far as matching a vehicle.

Confidence — an estimate of recognition quality, in percent. Vehicle confidence and plate confidence are measured separately.

Class — the type of the detected object.

Uptime — the share of time the camera was reachable.

Node — the server handling a camera's video stream.

WebRTC — the low-latency live video delivery protocol. Streams are published per resolution.

Archive — recorded video, reached by scrubbing the timeline.

Cargo

Shipment (cargo) — the whole logistical unit, with an origin and a destination.

Package — a physical item inside a shipment, with its own barcode. It is the package that binds to a vehicle.

Binding — the interval during which a package was on a particular vehicle. The binding history shows transfers.

Milestone — a landmark on a shipment's journey: received, loaded, transferred, delivered.

Public transport

Stop — a boarding point, with a code and coordinates.

Route — an ordered sequence of stops and the line built through them.

Costing — the routing profile the line is built with, depending on the vehicle type.

Assignment — binding a route to a vehicle with service days and a schedule.

On-time rate — the share of arrivals that met the schedule.

Data and integrations

Data source — the store the application works against: local sample data, the local database or the live API.

Outbox (change queue) — the edits made in local-database mode that are waiting to be sent to the server.

API token — a key letting an external program act in the system on your behalf, with your permissions.

MCP endpoint — the address compatible clients connect to, authenticating with an API token.

Webhook — a notification delivery method: the system POSTs a description of the event to a URL you supply.

Events and notifications

Event — a recorded fact: a zone entry, a start, an overspeed, an alarm and so on. Always recorded, regardless of subscriptions.

Subscription — your instruction about which events on which object should reach you. Personal to each user.

Delivery channel — where notifications go: email, Telegram, the app, a webhook.
