This is high-precision road network data for GIS and car navigation systems, compiled from road information covering approximately 1.3 million km nationwide.
In addition to information on road types, number of lanes, intersections, and structures such as bridges and tunnels, the database also includes a wide range of traffic regulation information, such as road closures, one-way streets, and restrictions on right and left turns.
We respond quickly to new road openings and road improvements, ensuring that our maps always reflect the latest road conditions.
In addition to routing applications such as car navigation systems, logistics systems, urban planning, and traffic simulations, it is also ideal for various GIS analyses utilizing road networks.
In optimizing logistics routes, traffic regulation information, along with the latest New road information list and width information, can be considered and utilized.
In urban planning and traffic simulations, the extensive road attribute data enables detailed analysis.
This can be used in local government road management operations to identify road types and restricted areas.
By distinguishing between smart interchanges and ETC-only roads, the accuracy of access routes to expressways can be improved.
This can be used to visualize and organize local roads and tourist routes in tourism and regional revitalization initiatives.
In addressing aging infrastructure in local governments, repair plans can be prioritized based on bridge and tunnel information.
Our map service can accurately display road types, names, and structures (bridges, tunnels, etc.).
The road network data includes a wide range of major traffic restriction information relevant to actual driving, such as road closures, one-way streets, no-turn/right-turn restrictions, and time-based restrictions. This information is assigned to each road link, allowing for route calculations that avoid restrictions during route searching.
Road network data is updated monthly, 12 times a year. Newly opened roads and roads that have been widened or renovated are promptly reflected in the data after thorough review based on on-site surveys, official documents, and information from relevant organizations. This allows for route calculations and map displays that reflect the latest road conditions.
ETC toll data can be used to accurately calculate tolls along routes on expressways and toll roads. Additionally, optional Vehicle type regulation contains information on restrictions for large vehicles and specific types of vehicles, enabling route determination and the creation of restriction-avoidance routes based on vehicle type. These contribute to highly accurate route design in navigation and logistics systems.
