Home Page

By default, Home shows the overview of all locations that are available.

Trajectory Trace Home – location overview with diagnostics timestamps and live status

Map View​

Clicking Show Map in the top right corner switches from the card grid to a map overview. All locations are shown as markers on the map. Clicking a marker opens the location. Click Show Dashboard to return to the card grid.

Login and New Locations​

The top right corner also shows your login status:

  • Not logged in: only public locations are visible. Click Sign In to log in.
  • Logged in: the account icon shows up to three letters from your email. You see public locations and locations covered by your location, organization or overall permissions. Open the account menu for Users and, where available, Organizations.

New Location is available when you own an organization or have overall owner permission. Choose the destination organization and enter the location details. The new location inherits that organization's permissions and appears in the overview after creation. See New Source to connect a data source.

Location Diagnostics​

Each location card shows the timestamps of the first and last data for each data type, if available:

RowWhat is counted
EntitiesTraffic objects (vehicles, cyclists, pedestrians)
SensorsTraffic lights, detector loops, weather masts
EventsAccidents, dangerous conditions, other events

Clicking a timestamp navigates directly to that time range in the location view.

The timestamps are refreshed periodically and automatically adjust their update frequency based on how recently a location was active.

The Home page also reloads location information once per minute to pick up updated timestamps. To recalculate the first and last timestamps for entities, sensors and events immediately, click on a location card. The card reloads when the calculation finishes. Recalculating timestamps requires maintainer or owner access, including for public locations.

Live indicator​

When live data is arriving, the last column shows a green • live chip instead of a static timestamp. The displayed count differs per data type because each uses a different active window:

  • Entities — unique objects seen in the last 500 ms
  • Sensors — sensors that reported in the last 2 minutes
  • Events — events received in the last 5 minutes
