NEXCO EAST Tohoku Regional Head Office (Sendai City, Miyagi Prefecture) has been operating the E4 Tohoku Expressway (hereinafter "Tohoku Expressway") Adatara Service Area (hereinafter "SA") Out-bound line and Kunimi SA Out-bound line since March 2021. We would like to inform you that we have started a demonstration experiment of "short-term limited parking space" from the 1st (Friday).
``Short-time limited parking spaces'' is a part of the parking spaces for large vehicles (5 spaces for each of Adatara SA (Out-bound) and Kunimi SA (Out-bound)) that can be used for up to 60 minutes. The purpose is to ensure drivers have more reliable opportunities to take breaks. In this demonstration experiment, "short-term parking spaces" will be set up at rest facilities where large vehicles often leave the SA/PA (parking area) without being able to park due to the presence of vehicles parked for long periods of time. We will examine changes in rest opportunities, congestion conditions including surrounding rest facilities, and effective maintenance locations. Customers using Adatara SA (Out-bound) and Kunimi SA (Out-bound) are requested to follow the information signs in the parking lot and use them appropriately.

1. Maintenance status of Adatara SA Out-bound line and Kunimi SA Out-bound line "Short-time limited parking space"

Information signs (see Figure 1) have been installed in the parking lot to guide you to the location of the short-term parking spaces. In addition, road markings (see Figure 2) have been placed to make it clear that the parking spaces are limited to short-term parking spaces.

2. Request for use

Customers using the "short-term parking spaces" are asked to follow the information signs and road markings inside the rest facility and leave within 60 minutes after parking.
Additionally, if you will be parking for more than 60 minutes, please use a parking space other than the short-term parking spaces.

3. Background to the introduction of “short-term parking spaces”

NEXCO EAST, NEXCO CENTRAL, and NEXCO WEST are working to expand the number of parking spaces in their SAs and PAs. However, in SA/PA areas, mainly in urban areas, there is a large proportion of vehicles parked for long periods of time, and the area remains congested. As a result, some vehicles are leaving SA/PA without being able to park, and it is thought that they are missing out on a much-needed opportunity to take a break.
By establishing "short-term parking spaces," we will ensure that more vehicles have the opportunity to park reliably.
In addition to Adachi Tara SA (Out-bound) and Kunimi SA (Out-bound), which will begin operation within NEXCO EAST jurisdiction, Kamikawachi SA (In-bound) will begin operations on November 28, 2020, and Hasuda SA (In-bound) will begin operations in Reiwa 5. It started operation on December 21st.
