East Nippon Expressway Co., Ltd., Central Japan Expressway Co., Ltd., West Japan Expressway Co., Ltd. have expanded the parking space to the congestion of the parking area that has become apparent in the rest facilities of Expressway. We are proceeding with our efforts.
We are pleased to inform you that we have summarized the expansion results for 2020 and the expansion schedule for 2021.

<Expansion of parking space>

　* The total value of the number of regular car squares and the number of large car squares including dual-purpose squares
　2020 results: Approximately 550 units
　Scheduled for 2021: Approximately 600 units

Please note that traffic restrictions may be involved during construction. For the status of each rest facility, please check the attached sheet [PDF: 167KB] or the website of each company.
In addition, since many customers will use the parking lot, we ask for your understanding and cooperation in the proper use of the parking lot, such as refraining from parking for a long time in the service area (SA) or parking area (PA).

1. 1. Parking area challenges

I. Congestion of large vehicles at night on weekdays

The situation of congestion due to lack of parking space for large vehicles, especially at night on weekdays, is still occurring. For example, at E1 Tomei Ebina SA (In-bound), long-term parking of 8 hours or more occupies about 60%, mainly at night on weekdays, and one parking space occupies a long time, so many vehicles can be used. As it disappears, it is one of the causes of the shortage of parking space for large vehicles.

II. Congestion due to concentrated parking use (mutual SA / PA, time zone)

Parking of large vehicles is biased towards SA/PA, which is close to major metropolitan areas such as metropolitan areas, and SA/PA, which is a certain distance away from major metropolitan areas. In addition, since the use of these SAs and PAs concentrates at the same time, it is difficult to properly utilize the SAs and PAs and the parking mass effectively.

III. Inappropriate use of parking space

Due to improper use, such as when a normal car is parked in a large car mass or a large car is stopped in a normal car mass, there is a situation where a vehicle that can be parked cannot be parked.
Also, the dual-purpose mass is designed to be used when the parking mass of a normal car or a large-sized car is full, but since it has not been used in such a way, the original function cannot be exhibited. You can see an example.

2. Major initiatives in 2020

I. Maintenance of parking space

A) Expansion of large vehicle mass

[Case of E19 Chuo Expressway Enakyo SA (In-bound
　On the E19 Chuo Expressway Enakyo SA (In-bound), a shortage of large vehicle mass became apparent mainly during the night hours on weekdays. Therefore, in addition to changing the arrangement of parking lots on the existing site, we will increase the number of large vehicles that can be parked by increasing the number of parking spaces that can be used by both large vehicles and ordinary vehicles by about 1.4 times. We have solved the shortage of large vehicle mass.

By expanding the mass of large vehicles, the shortage of mass of large vehicles during the night hours on weekdays has been resolved. However, long-term parking is one of the causes of lack of parking space, so please refrain from long-term parking and ask for your understanding and cooperation so that many customers can take breaks efficiently.

B) Maintenance of a "combined mass" that can be used by both ordinary and large vehicles

In order to use the limited parking area efficiently, we are proceeding with the development of a "combined mass" that can be used by both ordinary and large vehicles (in NEXCO CENTRAL, the "combined mass" is clearly indicated by the blue line). When using the "combined space", please give priority to the parking spaces for ordinary cars and large vehicles, and use the "combined space" when each parking space is full. If one ordinary car is parked in the "combined space", large vehicles cannot be parked, so please cooperate in parallel parking of ordinary cars so that more customers can park.

C) Expansion of large vehicle mass utilizing the land of rest facilities

[Example of E2 Sanyo Expressway Fukuyama SA (Out-bound
NEXCO WEST, on the E2 Sanyo Expressway Fukuyama SA (Out-bound), the park area has been changed to a large vehicle mass, and the number of large vehicles that can be parked has been increased 1.2 times from 80 to 97 to alleviate congestion. I will. In addition, a total of 9 parking spaces for double-connected trucks have been newly installed.

D) Installation of "normal holiday operation switching mass" based on the actual usage

[Case of E4 Tohoku Expressway Chojahara SA (Out-bound
NEXCO EAST, E4 Tohoku Expressway Chojahara SA (Out-bound) has set up a "weekday operation switching mass" that switches the operation of parking masses on weekdays and holidays, based on the fact that the actual usage by vehicle type differs between weekdays and holidays. An orange frame is attached to the parking space to distinguish it from other parking spaces, and the LED guidance display board displays "large car" on weekdays and "small car" on holidays to guide customers to park in an easy-to-understand manner. doing.

II. Call for proper use of parking space

Traditionally, the proper use of parking spaces for large vehicles and regular vehicles has been called on the websites of Expressway companies, posters on SA/PA, and road patrols.
In particular, regarding the dual-use mass, which has been under development in recent years, we paid attention to the difference between the peak demand for parking for ordinary cars mainly during the daytime on holidays and the peak demand for parking for large vehicles during the night on weekdays. As an initiative, we are calling on the websites of Expressway companies and posters on SA/PA to spread the understanding of the purpose.

III. Maintenance of reserved parking lot exclusively for double-connected trucks

NEXCO3 is in the process of gradually developing parking spaces for double-connected trucks in response to the relaxation of special vehicle traffic permission standards in January 2019, but vehicles other than double-connected trucks will park. Challenges are occurring. In addition, the parking lots for large vehicles are crowded mainly at night at the rest facilities of the Shin Tomei Expressway, and the parking lots of the rest facilities cannot secure sufficient parking space for double-connected trucks. Therefore, in NEXCO CENTRAL In-bound a parking lot exclusively for double-connected trucks that can be reliably parked outside the Hamamatsu Inasa Interchange and Ashigara SA (up) by prior reservation. The operation started on the 1st of the month. NEXCO3 will continue to make efforts to secure break opportunities for truck drivers.

3. Efforts to prevent congestion in 2021

I. Maintenance of parking space

In 2021, we plan to install about 600 new parking spaces at 44 SAs and PAs nationwide.

Number of expansions in FY2020 (actual) and number of major expansions in FY2021 (planned)

1. : () Indicates the number of vehicles including the dual-purpose mass (counted as two ordinary vehicles per dual-purpose mass)
2. : Number of large vehicle masses including dual-purpose masses

Note) The number of parking spaces in the table is the current plan, and may increase or decrease as concrete design and construction progresses in the future.
Note) By increasing the number of dual-purpose masses, congestion is alleviated even during times when there are many ordinary cars.

II. Efforts to further level the use of parking lots

　At some rest facilities of E1 Tomei and E1A Shin Tomei, the road-to-vehicle wireless communication device (free flow antenna) utilizing ETC is used to grasp the full-vacancy information of each parking lot in real time, and it is displayed on the information board or website. We have been trying to equalize the use of parking lots by providing detailed information on the availability of parking lots and the congestion status of rest facilities.
From 2021, NEXCO CENTRAL Large similar efforts to E1 Tomei, E1A New​ ​Tomei, E19 / 20 Chuo Expressway, E1​ ​Meishin, E1A New Meishin, E1A Isewangan Expressway and E23 Tomei Expressway. ..

III. Other considerations

A) Examination of the impact of late-night discounts

The midnight discount was introduced in November 2004 as a discount for vehicles used at midnight for the purpose of improving the roadside environment of general roads, such as improving the noise environment due to the decrease in night traffic on general roads. The effect has been confirmed. On the other hand, there are issues such as long-term parking by vehicles waiting for the late-night discount at rest facilities near the Tokyo metropolitan area before midnight when the late-night discount is applied, and staying of vehicles waiting for the discount at tollbooths on the main line. In the future, in order to alleviate congestion in the parking area, we will consider in cooperation with related organizations based on discussions such as calling for the appropriate use of large vehicle mass and reviewing the discount application conditions at the National Land Trunk Road Subcommittee.

B) Consideration for securing break opportunities by Large

Expressway, the Ministry of Land, Infrastructure, Transport and Tourism aims to halve the 100 sections where the distance between rest facilities is approximately 25 km or more from February 2017. , ETC2.0-equipped vehicles are being tested at 23 roadside stations nationwide. From March 2020, we have increased the time available for temporary evacuation from the previous 1 hour to 3 hours, and are continuing the demonstration experiment, based on the opinion that "the time is too short to take a sufficient break". In the future, in order to secure a good driving environment, including securing break opportunities for large vehicles, we will consider collaborating with the Ministry of Land, Infrastructure, Transport and Tourism to Large
