Roads Management Insights release notes

Updates to real-time traffic information data formats and schema: You should migrate to the new fields before November 9, 2026, to ensure uninterrupted service.

• Replaced the speed_reading_intervals field with a speed_reading_offsets field in both real-time Pub/Sub messages and the recent_roads_data BigQuery table. The new field records speed readings based on the offset in meters from the start of the route (for example, "start_offset:0, end_offset:50, speed:NORMAL", "start_offset:50, end_offset:80, speed:TRAFFIC_JAM").
• Introduced a fourth speed reading bucket, TRAFFIC_JAM_HEAVY, within the new speed_reading_offsets field. The speed readings align with the four colors shown in the Google Maps traffic layer.
• Added a new retrieval_timestamp field to real-time Pub/Sub messages, formatted as an RFC 3339 string, enabling native BigQuery TIMESTAMP auto-casting for customer subscriptions. This will replace the current retrieval_time field.
• Converted the nested travel_duration field in real-time Pub/Sub messages to two separate fields (duration_in_seconds and static_duration_in_seconds), to be consistent with the BigQuery schema. These fields will replace the current travel_duration field.
• Both the new and old fields will be populated until the deprecation of the current fields.

Added support for the patch, batchUpdate and batchDelete endpoints in the Road Selection API. Developers can now update or delete SelectedRoute resources either individually or in batches of up to 1,000 at a time.

Introduced Google road segment IDs (represented as Place IDs) for Roads Management Insights historical and real-time route traffic data. Specifically, a new road_segment_ids field is added as a repeated string field into the following locations:

• Historical Data: historical_travel_time and recent_roads_data tables in your BigQuery dataset.
• Real-Time Data: Pub/Sub topics (rmi-roadsinformation-*).

General Availability of IAM Roles.

Resolved rounded duration_in_seconds discrepancy. What used to be rounded to an integer is now returned as a granular floating point value.
