Traffic incident missing on HERE map – how to report and why it happens

Short Description
---------------------

When a traffic incident does not appear on a Traffic Vector Tile map, how to report it through the correct HERE support channels.

Applies To
--------------

HERE Traffic Vector Tile API
HERE Traffic API v7
HERE SDK (Android, iOS, Flutter, Web)
HERE Maps API for JavaScript

Issue
---------

A traffic incident (e.g., accident, road closure, or roadwork) is missing or not displayed on the map.

You may find the following issues like:

Traffic incident not shown
Missing traffic data
Incident not returned by API
Traffic layer incomplete

Cause
---------

The Traffic Vector Tile API is a read-only visualization service.
It displays traffic data that has already been processed and published by HERE backend systems.

Traffic incidents shown on the map:

Are aggregated from multiple data sources
Undergo verification, filtering, and deduplication
Are published only after processing

Therefore, an incident may be missing if:

It has not yet been detected or verified
It is not covered by available data sources in that region
It has been filtered or merged as part of quality control
It has expired or been removed from the active dataset

Resolution
--------------

### Important

The Traffic Vector Tile API does not support reporting or submitting traffic incidents directly.

It is a read-only service, and no API endpoint exists for submitting new incidents.

### How to Report a Missing Traffic Incident

#### For HERE Platform Customers

1. Log in to the HERE Platform and navigate to Support Portal: https://platform.here.com
2. Create a support ticket
3. Include the following information:
Location (latitude/longitude or map link)
Date and time of the incident
Type (accident, closure, roadwork, etc.)
Additional details (screenshots, logs, external references)
4. The HERE Support team will:

+ Validate the request
+ Escalate it to the traffic data team for review

#### For End Users

If you are using a HERE-powered application (such as HERE WeGo), use the in-app feedback functionality where available.

Alternatively, HERE Map Creator can also be used for reporting map errors including but not limited to missing traffic incidents.

Expected Behavior
---------------------

Traffic incidents are displayed only after verification and processing
Not all real-world incidents are immediately available in the system
Data availability varies by region and source coverage

Additional Information
--------------------------

Traffic data in HERE services is processed through:

Multi-source ingestion (government, partners, sensors)
Automated and manual validation
Deduplication and aggregation

This ensures consistent and reliable traffic information across APIs and map services.
