Hanshin Expressway Route 11 (Ikeda Route Osaka bound) nearby the Tsukamoto Junction

Overview of the target sections

The Hanshin Expressway Route 11 (Ikeda Route) is one of the major routes that connect the Osaka International (Itami) Airport (ITM), Meishin and Chugoku Expressways, and other trunk routes with Osaka City. The Tsukamoto Junction (Osaka bound) is located on the right bank of the Yodo River, outskirts of Osaka city center. Roads around the junction carry a large amount of traffic with two lanes for each direction with a complicated road environment with S-shaped curves, sags, and Tsukamoto interchange. Shock waves frequently occur at convergences, curves, and the bridge over the Yodo River.

Hanshin Expressway Route 4 (Wangan Route Osaka bound) at the Ohama-Sambo section

Overview of the target sections

The Hanshin Expressway Route 4 (Wangan Route) is one of the major routes that connects the southern part of Osaka, including Kansai International Airport (KIX), with the center of Osaka City. It is also an access route to Yumeshima, the venue of Expo 2025 Osaka, Kansai. The traffic volume rises in the morning hours at the Ohama-Sambo section, which holds two lanes for each direction. Because of the complicated road environment such as Ohama Junction, left-hand curves, and sags, we occasionally observe shock waves at these locations.
