Promotion of new technological developments

STAGE1STAGE2Leveraging latest technologies
in new construction and renovation works

We will promote electricity efficiency through the use of new equipment and construction equipment in new-build and renovation projects. We will also reduce CO2 by using construction materials created by new technologies.

  • ○In the short term, promotion of ICT in construction (Stage 1)
  • ○Over the long term, promote increased use of innovative construction equipment (electric, hydrogen, biomass, etc.) through usage rules, including harnessing construction materials created by new technologies

STAGE2Preparing for the popularization of fuel cell vehicles

When it comes to preparing for the popularization of next-generation vehicles and fuel cell vehicles (FCVs) in particular, we will investigate the possibility of building hydrogen stations, based on automotive industry trends and the state of uptake of FCVs.

STAGE1Installation of renewable energy generation facilities
to power the Metropolitan Expressway

In addition to procuring from zero-emission electricity suppliers, we will also pursue renewable generation facilities to supply the Metropolitan Expressway, such as solar installations.

Introduction of renewable energy

We are installing solar and wind generation in parking areas and tunnel entrances, for example.
The electricity produced is used to supplement the power required for tunnel ventilation,
in parking area buildings, to light bathrooms and more.
We will continue to increase our adoption of renewable energy.

STAGE2Upgrading of traffic control system

We will provide traffic information adapted to diverse needs.

  • ○Facilitation of traffic flow and network optimization through installation of a next-generation mobile communication system that leverages large volumes of data such as individual vehicle location data and images
  • ○Provision of information using probe data, etc
  • ○Information support for driverless vehicle operation

STAGE2Strengthening nodal functions

We will consider ways of strengthening nodal functions such as piloting mobility hubs,
adapting further to the MaaS society and support more efficient human mobility.

*1 MaaS :
Mobility as a Service. A service that seamlessly connects the user to transportation options other than their own vehicle, using ICT

Development of eco-friendly Parking Areas

STAGE1Upgrading of EV chargers and conversion
to clean energy sources

In addition to upgrading our EV chargers, we will pursue the use of clean energy by harnessing renewable power sources.

Promoting the Use of ZEV

ZEV (Zero Emission Vehicle) refers to a vehicle that does not emit CO2 during vehicle operation, such as plug-in hybrid and electric vehicles. We have installed quick chargers to support and promote ZEVs. To encourage the use of electric cars, quick chargers for electric vehicles are provided in eight parking areas (Heiwajima (inbound), Yoga, Yoyogi, Shimura, Yashio, Ichikawa, Daikoku, and Kawaguchi). Therefore, electric vehicle users can use Metropolitan Expressway with peace of mind.

STAGE1STAGE2When renovating parking areas,
we look to adopt eco-friendly spatial design,
materials and equipment

We will seek energy efficiency by installing new equipment when renovating facilities.

○With a focus on the carbon sequestration capacity of wood - and for the sake of healthy and robust domestic forestry - we will pursue the timber construction of facilities such as toilets and information kiosks as part of the "Second Urban Afforestation"(STAGE1)
○Use EFTE (a heat-resistant fluorine-based plastic) *1 film to allow in more natural light and reduce lighting requirements (Stage1)
○Reduce energy consumption by adopting passive design concepts *2 in spatial design(STAGE2)

*1. EFTE (a heat-resistant fluorine-based plastic): UV-resistant, weather-resistant and transparent material suited to long-term outdoor use
*2. Passive design: A design methodology that reduces environmental footprint by using the natural energy of solar heat and light as well as wind instead of machinery in a building

Eco-friendly Parking Areas

The Bayshore Route Oi Parking Area (westbound and eastbound), Yoyogi Parking Area and Kahei Parking Area are Eco-friendly Parking Areas, equipped with environmental technologies such as water-saving toilets, solar LED blocks and LED downlights. We will continue to implement eco-friendly initiatives at other parking areas going forward.

Water-saving toilets

We use water-saving toilets and various measures to prevent odors and stains.

Solar LED block

Solar energy is stored during the day, and the LED blocks light up automatically to guide customers safely after dark.

LED down power

LED downlights are used for indoor lighting to save electricity.

STAGE1Promotion of greening of road space

We are also planting vertically in narrow sites.

Greening of road spaces

We are planting out road spaces with the goals of improving the urban landscape and motoring conditions,
alleviating the heat island effect and preventing global warming.
Along roads, parking areas and junctions, we are working to establish greenery without neglecting the surrounding environment and maintenance.

STAGE1Food loss reduction initiative

We will reduce emissions of CO2 arising from disposal of food by reducing food losses, which constitute 8-10% of the world's greenhouse gas emissions.

STAGE2EVs and PHVs as a source of emergency power

We will harness EV and PHV batteries as emergency sources of electricity in case of power cuts, vehicles in need of charging, etc.

Shutoko vision for 2050

  • Adoption of renewable energy in parking areas to supplement electricity supply
  • Promoting use of timber in building
  • Reduced use of plastics in Parking Area shops, simplified packaging
  • Food loss reduction initiative
  • Table service, cleaning performed by robots
  • Remote working facilities installed

Improved roadside environments

STAGE1Noise and vibration countermeasures

We will implement measures against noise and vibration
in order to protect the comfortable living conditions of local residents.

Installation of sound insulation walls

Sound insulation walls are installed for the purpose of reducing noise along the road in order to maintain a comfortable living environment.
We are currently working on adopting sound insulation walls to not only reduce noise but also take landscape into account.

Installation of backside sound absorbing plate

The back side sound absorbing plate is a plate installed on the underside (back side) of the viaduct. By installing a sound absorbing plate on the back side, it is possible to reduce the noise from the street reflected on the underside of the viaduct.

Maintenance of high-performance pavement

Normal pavement

High-performance pavement

By using a material with many voids in the pavement material, the compression of air between the road surface and the tire is reduced. There by the noise (air pumping noise) generated when the compressed air is released due to the friction between the tire and the road surface of the automobile is reduced. We will proceed with the maintenance of high-performance pavements.

Implementation of non-joint construction

Non-joint construction

By eliminating the joints on the road surface, we will realize smooth running without shocks, reduce noise and vibration, and proceed with non-joint construction. After construction, there is no need to repair the joints (replacement of joints), so it is possible to reduce traffic congestion associated with repair work.

Please avoid overloading because it can damage the roads and cause noise and vibrations

STAGE1STAGE2Harmony with nature through
green space development

When procuring electricity for the Metropolitan Expressway, we will give priority to generation from renewable sources.
We will continue to provide technical consulting services.

STAGE1Countermeasures for air pollution

We are trying to improve air quality for residents living near the Kanagawa Route No.1 Yokohane Line,
which runs through highly built-up residential areas, by applying an environmental road pricing discount.
This is being used to divert extra-large and large vehicles to the Bayshore Route instead.

Environmental road pricing discount

We are promoting the use of the Bayshore Route instead of the Yokohane Line to improve the environment along the Highway by applying an environmental road pricing discount to large and extra-large vehicles using the Bayshore Route or the Kawasaki Route.
