Nakayama-machi, Midori-ku

　In the Nakayama-cho district of Midori-ku, many cars pass through the target section (in zone 30 area and school road) avoiding the surrounding arterial roads, and pedestrians were difficult to cross at the pedestrian crossing. . In addition, the analysis results of ETC2.0 big data also confirmed that the speed was exceeded, and it was dangerous for commuters, commuting to school and local residents, and it was necessary to take immediate action.
　In response to local issues, we established a "Traffic Safety Measures Council" consisting of local residents and elementary schools, police, the Ministry of Land, Infrastructure, Transport and Tourism, Yokohama City, etc., was established in 2018, and decided to proceed with the study of safety measures.

　In 2018, we exchanged opinions at the "Traffic Safety Measures Council" and conducted a demonstration experiment (test construction of smooth pedestrian crossings, humps, etc.).

What is a Smooth Crossing?
Raising the pedestrian crossing to the height of the sidewalk makes it easier for drivers to recognize, reduce the speed of the car, and allows pedestrians to cross safely.

What is a hump?
By installing trapezoid convexes on the road, the speed of the car.

What is the narrowness?
By narrowing the road, the speed of the car is reduced by passing each other without passing.

What is Intersection Color Pavement?
The driver is painted in red to alert the driver.

　Since we were able to confirm the speed suppression effect of the demonstration experiment (test construction of smooth pedestrian crossings, humps, etc.), we exchanged opinions with local residents on the measures and installed smooth pedestrian crossings and humps in March 2020. did.

　In order to verify whether the speed suppression effect of installing smooth pedestrian crossings and humps is being demonstrated, the driving speed of the car before, 1 month, 3 months, 6 months, 1 year, 1 year and 6 months after the countermeasures. Data was analyzed.
　As of September 2021, one year and six months after the implementation of the measures, it has been confirmed that the effects are still continuing.

　 Zone 30 Plus is an area regulation "Zone 30" with a maximum speed of 30 km / h and a "physical device" such as humps and smooth pedestrian crossings in order to further promote the development of safe and secure traffic spaces with priority on living roads. Road managers and police are working together to improve traffic safety by appropriate combination with "devices".
This time, "Midori-ku Nakayama-cho district" has been set to "Zone 30 Plus".
