This data covers the nationwide implementation of "Zone 30" speed limit measures on residential streets.
It can be utilized in car navigation systems, ADAS (Advanced Driver Assistance Systems), and traffic safety simulations for visualizing speed-control zones and providing driver alerts.
It can be used in navigation systems and ADAS (Advanced Driver-Assistance Systems) to provide safety driving support on residential roads, such as alerting drivers who enter a Zone 30 area to be careful about their speed.
Visualizing Zone 30 areas on a map allows for analysis of the extent and distribution of speed limit measures, which can be useful in formulating safety measures that take into account their location relative to accident hotspots and school routes.
In traffic safety simulations, it can also be used to verify changes in vehicle speed due to the setting of a Zone 30 area, and the effect of reducing the risk of collisions with pedestrians.
Zone 30 is a traffic safety zone located in residential areas and around schools, where the maximum speed of vehicles is limited to 30 km/h. This information is publicly available as open data from the National Police Agency.
This data is intended to be used in conjunction with road data, with the aim of providing users with safe and secure guidance during route planning.
It can be used to detect when a vehicle is entering a Zone 30 area and to warn drivers about their speed.
