Visualizes the connections between lanes and provides accurate guidance even at complex junctions.
- We clarify the lane-by-lane connections at junctions, merges, and intersections, and organize which lane connects to which lane.

Lane Connectivity
Lane connection information data is a dataset that defines the connection relationships at the lane level on expressways, including lane inflow and outflow at junctions and merges.
This describes the leakage relationship.
By understanding the direction of travel and connectivity within each lane, it becomes possible to provide drivers with advanced guidance such as voice guidance and lane illustration displays, resulting in safer and more accurate navigation.
The structure, which visualizes the relationship between preceding and succeeding lanes, allows for detailed determination of "which lane can be accessed from which lane" at intersections, and can be used to optimize voice guidance and lane selection.
Data Details
Detailed information such as lane number, direction of travel, and travel section is provided.
- Each lane is assigned a lane number, direction of travel, and direction codes such as straight ahead or left/right turns, allowing for detailed understanding of actions at junctions and merge points.
*This is optional data to be used in conjunction with the "Road Network Data".
Monthly updates adapt to changes in road structure.
- Through 12 regular updates per year, we quickly respond to changes such as newly constructed roads and alterations to junctions and merges, ensuring that we always provide data that reflects current realities.
*This is optional data to be used in conjunction with the "Road Network Data".

Expected usage
To enhance lane guidance in navigation systems, based on lane connections at junctions and merge points,
The system clearly indicates which lanes are passable through voice guidance and lane diagrams, helping drivers select lanes smoothly.To improve the accuracy of guidance in ADAS (Advanced Driver-Assistance Systems), more precise lane selection, warnings, and driving guidance are provided based on lane-level connectivity information. This also contributes to traffic congestion avoidance and accident prevention.
FAQ
What are the potential uses of Lane Connectivity?
Lane Connectivity allows us to visualize the inflow and outflow relationships at lane-by-lane levels at junctions and merging points,
It can be used to enhance lane guidance displays and voice guidance in navigation systems.
For example, it becomes possible to optimize visual and audio guidance such as, "Please proceed straight in the second lane from the left."
Yes, it will.
How often is this data updated?
Regular updates are carried out 12 times a year (monthly), including new road construction, changes to lane structure, and changes to the structure of intersections.
We have a system in place to quickly reflect changes. Our system can always be operated based on the latest transportation environment.
How detailed is the information regarding lane numbers and direction of travel?
Each lane has detailed attributes recorded, including lane number, direction of travel, possible connecting lanes, and traffic classification (straight, right/left turn, etc.). This improves the accuracy of lane guidance for drivers.
