Fifty-five percent of the world’s population already live in cities. By 2050, that is expected to increase to 68 percent, representing 2.5 billion more urban residents, according to the United Nations.i As populations grow, cities are faced with the challenge of how to accommodate this growth and manage their transportation systems. There are constraints in funding, in dealing with infrastructure and development, and in retaining a great quality of life that includes ever safer, more convenient and more sustainable mass transportation solutions within and between cities.
Urbanization will continue. With billions of people moving between home and work or school every day, plus the need to transport goods in a safe and efficient way, solving these issues in a sustainable manner is essential for vibrant societies.
Smart cities will prioritize sustainable mobility.
Intelligent rail plays a key role in meeting these challenges. Rail provides high-capacity, low-emission solutions to high-density urban areas, transporting suburban commuters to and from metropolitan areas, and making multimodal connections to airports and ferries. Smart cities can become more sustainable with autonomous, on-demand and networked rail services.
Although the transition to electric and autonomous vehicles may improve sustainability, it won’t address more pronounced problems such as congestion or the stresses to aging infrastructure. Electric vehicles can improve environmental conditions in cities, but the positive impact is limited if the power to charge these vehicles is generated from fossil fuel–based power plants. Autonomous vehicles can improve mobility, with the caveat that more vehicles will equal more congestion.
Rail, on the other hand, is a safe, effective way to move large numbers of people quickly and reliably — and modern, intelligent rail systems are evolving to be economically sustainable and are more environmentally friendly. Intelligent rail is a key asset for end-to-end, multimodal service.
Intelligent rail systems strive to deliver environmental, economic and social value to customers, whether they are passengers, transit operators or the public sector. In partnership with these three critical groups of stakeholders, the rail industry must continue to conceive, design, build, co-create, implement and otherwise offer solutions that relieve congestion and reduce pollution. To ensure the livability of a smart city, the industry must deliver intelligent rail solutions that run efficiently, reliably and safely — and improve the quality of life for everyone.
Modern rail systems are much more than just well-built, safe trains — they’re intelligent, fast-moving ecosystems. Intelligent rail delivers end-to-end, multimodal service that solves mobility problems while making the best use of available funds.
For example, Hitachi developed intelligent asset management in answer to a customer’s need for integrated digital rail solutions. As a result, Hitachi can provide seamless support to transit authorities or rail operators with on-train and wayside digital solutions, real-time monitoring and supervision, alarms and warning notifications, condition-based maintenance, data management, analytics and advanced data processing, remote control and management, life cycle asset management, and planning and decision support.
Intelligent rail helps cities optimize investments that have already been made so that they can deliver “the mobility of tomorrow.” The goal is to improve the end user’s experience without compromising on sustainability.
Even more exciting for today’s transit operators is the mobility-as-a-service model of public-private partnerships that leverages limited budgets in ways that improve the operation and maintenance of transport systems. Rather than having to make large, upfront expenditures, in the public-private partnership model, cities partner with companies like Hitachi to build, operate and maintain these intelligent rail systems. Not only does this model change the funding model for key projects, it also means that private companies have a long-term, vested interest and investment in the outcome. The better the system performs, the more passengers will want to use it, which results in continuing revenue for the operators.
An example of this model in practice can be found in Ontario, Canada, where Hitachi is a member of a consortium that is implementing such a project. The consortium is designing, building, financing, operating and maintaining the Hurontario LRT, a light-rail system in the Toronto area. The system, due to open in 2024, will better connect passengers to other modes of transport in a cost-effective manner.
Similarly, Hitachi is building a new driverless metro in Honolulu with the Honolulu Authority for Rapid Transportation (HART) in Hawaii. Designed as the heart of the island of Oahu’s multimodal transport system, HART will be America’s longest automated, driverless, urban light metro system. By 2030, it is expected to handle more than 120,000 passenger trips each day while reducing significant use of motor vehicles. ii
Hitachi brings decades of expertise and experience to enable such intelligent, modern rail systems — not only in railway signaling and systems technology but also in information technology, electronics, software development and IoT technology. With our long history of successful systems design, engineering, integration and operation, we are helping smart cities everywhere to implement and run sustainable, integrated transportation systems.
One of the most exciting elements of intelligent rail systems is their ability to collect and analyze data to help the customer better predict when and exactly where to concentrate their maintenance and repairs — and even warn if a failure is imminent. When a physical device requires repair, intelligent rail systems help the operators understand where the wear and tear on the system is located so that they can plan for the repairs ahead of a breakdown. Hitachi’s intelligent rail systems can deliver predictive maintenance that helps the operator avoid potential shutdowns — reducing the inconvenience to passengers while saving money. In manufacturing, McKinsey estimates that predictive maintenance will create between $500 billion and $700 billion of value for businesses. iii
The diagnostics tools in predictive maintenance solutions not only identify issues but can help operators fix software issues remotely. This means the system can detect and adjust to real-time conditions. For example, a major cause of train delays in subway systems is when the doors won’t close. With IoT components such as sensors added to the doors, intelligent rail systems can self-diagnose, identify and locate the problem that needs to be fixed, dramatically reducing such delays.
An integrated, connected intelligent rail system can also use its data to meet increases in passenger demand. For example, Hitachi’s driverless metro system in Copenhagen adjusts the frequency of service by monitoring passenger numbers in real time. It detects people flow, adjusting the schedule of trains at peak times by sensing the number of people on the train platforms. It automatically sends more trains as needed. That means shorter waits, less congestion and a much smoother trip home after a big sporting event, for instance. And this translates to happier passengers who are more likely to use that transit system again.
Transit authorities could also reduce congestion and improve the travel experience for passengers by partnering with local vendors in creative ways. Imagine getting an alert on your smartphone offering a free cup of coffee while you wait for the next train. Additionally, dynamic scheduling in this mobility-as-a-service model means your phone can sync bus and train times, so passengers can step off the train and quickly onto their bus for home. It also adjusts these multimodal schedules by taking into account road conditions, traffic patterns and the weather.
By sustainably managing the movement of people and goods across different modes of transport, cities can dramatically improve service to their citizens. The quality of urban life is also enhanced when citizens can attend and participate in their rich mix of culture, arts and sports without having to worry about their trip home. Hitachi Rail meets these needs through intelligent rail systems.
Hitachi works to deliver social innovation in transport as a partner to its customers and by investing in innovative solutions. Our goal is to improve the journey for passengers, operators and public authorities. We collaborate with our customers to co-create solutions through continuous value engineering to identify the approach that best meets their needs. Our focus on social innovation is at the heart of the design, implementation and operation of our systems with our commitment to powering good.
Hitachi estimates that its intelligent rail services and solutions helped 18 billion people travel from one point to another last year. But that’s just the beginning: By leveraging our social innovation business model, it’s believed that carbon emissions can be reduced by as much as 10 percent, congestion by as much as 20 percent, and road traffic accidents by 25 percent.iv By improving their mobility systems in scalable, sustainable ways, our cities can now enrich the quality of life for all citizens.
