Kilometer post data
MapFan DB 's kilopost data is precise distance reference point data that records the location information of road reference point markers (kilometer posts/distance markers) installed on expressways throughout Japan at 100m intervals.
Based on actual distance markers installed along the roadside and in the median strip, the data is compiled as location information (point data). Because the kilometer post data is precisely matched to our road network, accurate display on maps is possible.
By leveraging the "accurate location identification capabilities" and "precise distance information" of kilometer post data, advanced data utilization is possible in a wide range of fields, including GIS, such as identifying and managing accident and breakdown locations, and providing distance guidance in navigation systems.
How can kilometer post data transform your business? We present specific use cases and examples that offer hints for solving challenges in our case studies section.
Data Details
- Kilometer post data is compiled for the entire national highway network.
- Each point contains information about the direction of travel and distance from the starting point, which can be used for accurate location determination in GIS and navigation systems.
- While maintaining consistency with the road network, the system is updated 12 times a year to adapt to changes in route conditions.
*This data is provided as an option for the road network.

Expected usage
- Navigation, information provision, and safety support
In navigation systems and traffic information services, it plays a crucial role in perfectly synchronizing digital information with local signs. By identifying precise locations on the road using a common standard such as "XX kilometer post," and linking this with local conditions (broken-down vehicles, accidents, road closures due to disasters, rest stops, etc.), it provides specific and highly accurate guidance. This allows drivers to quickly grasp the situation with intuitive information that matches local signs, such as "the next rest stop is near the 152.0 kilometer post," leading to safer driving without confusion or anxiety.
- Expediting emergency response and insurance operations
When an accident or breakdown is reported on a highway, the system can instantly determine the precise latitude and longitude of the scene by linking the "XX kilometer post" value provided by the caller with this data (location information of the kilometer post). This enables accurate navigation and routing in systems that support road services and the dispatch and arrival of emergency vehicles, significantly reducing emergency response time.
Furthermore, automobile insurance companies can expedite accident response and enhance risk analysis using geographic information through accurate data analysis based on the location of accidents (kilometer post values).
- Improving the efficiency of road management and infrastructure maintenance (for administrators)
This system is useful for highway administrators in accurately managing target sections based on kilometer posts during road infrastructure inspection and repair work. By recording and visualizing equipment requiring repair and deteriorated road surface areas on a map using kilometer post information, the process of considering countermeasures can be streamlined.
- Analysis for traffic safety and policy planning (for planners and analysts)
By visualizing the precise location information of kilometer posts on a GIS, it can be used for detailed risk analysis of specific sections, such as traffic volume, accidents, and the concentration of facilities between arbitrary kilometer posts (e.g., from 100.0 km to 110.0 km). This allows for identification of accident-prone areas and near-miss areas.
Furthermore, the areas where incidents (accidents, near misses, etc.) occur can be accurately represented and visualized for each route using kilometer post information. This allows for the identification of routes and sections requiring countermeasures, and can be used for evidence-based policy planning, such as considering traffic regulations.
FAQ
Is it possible to manage and analyze vehicle accident locations and road infrastructure management information using kilometer post values?
Yes, data linkage and analysis using distance information from kilometer posts as the key is possible.
・Location:
By using the kilometer post values recorded in accident information and equipment data (e.g., 125.4km point on the uphill lane) and linking them with the precise location information (latitude and longitude) included in this data, the location of the incident can be instantly identified on a map.
• Efficient management:
By linking road infrastructure inspection and repair history with kilometer post information, efficient section management and risk analysis become possible, such as determining "which infrastructure is located in which kilometer post section" and "which sections have a high number of accidents."
How often is the data updated?
Kilopost data is updated regularly 12 times a year (monthly). We always provide data that matches the latest network configuration.
Please tell me the range of routes included in the data.
This data covers major intercity expressways.
How can kilometer post data be used in navigation system guidance?
Kilopost data allows for the precise identification of locations along roads in the form of "Kilometer Post XX." Local conditions such as accidents, broken-down vehicles, traffic congestion, and rest stops are linked to the kilometerpost values and displayed on the navigation system. In other words, it can provide not only abstract distance information such as "10km to the next service area," but also intuitive and accurate guidance that matches local signs, such as "The next rest stop is near kilometer post 152.0."
Furthermore, drivers can instantly grasp their current precise location and direction of travel by comparing the information on local kilometer markers with the information on the navigation screen.
I would like to find the location of a specific kilometer post or the distance from a certain point to a kilometer post. Is this possible by purchasing GeoTechnologies, Inc.' "Kilometer Post Data"? Also, what is the data format?
Yes, it is possible. Our "kilometer post data" is provided in a data format (Shapefile or PostGIS format) that can be easily displayed and visualized using GIS software. Therefore, the precise location and distance information (in 0.1 km increments) of kilometer posts can be easily displayed and visualized on a map, and used for location identification and distance calculation.
Furthermore, when combined with our road network data, it is possible to simultaneously acquire and utilize detailed attribute information such as route names (e.g., XX Expressway)and inbound/outbound lanes, allowing for smooth use in advanced applications such as road asset management, operation analysis, and accident analysis.
