Welcome to the transit of the future

Intelligent connectivity – taking transit into the future

The sensors, analytics and pervasive connectivity transforming many sectors have vast potential to make transit safer, more efficient, sustainable and cost-effective —across an entire transit system, above and below ground.

By providing fine-grained, real-time control over every aspect of transit operations, virtualised network communications enable a wide range of applications and solutions that benefit transit authorities, passengers, as well as other municipal stakeholders.

Safer for everyone, everywhere

Most transit systems protect passengers and property with on-site security staff and closed-circuit television (CCTV). But security teams are largely reactive and CCTV on its own is always passive.

Injecting data analytics into transit operations can increase safety and strengthen security, enabling CCTV systems to actively notify security teams when unauthorised personnel enter off-limit areas or maintenance crews are onsite without mandatory safety gear. It also allows staff and emergency personnel to respond more efficiently when help is needed and make on-the-fly service adjustments, as required. Push notifications can then be used to inform passengers and recommend alternate routes to prevent station overcrowding. In Toronto, the Toronto Transit Commission (TTC) developed a solution to measure passenger volumes based on anonymised association data from the Wi-Fi network. This application has been configured to generate alerts when platform conditions indicate overcrowding. This solution was further adapted to support physical distancing measures due to the COVID-19 pandemic – giving TTC operators the information needed to make safer trip planning decisions.

Seamless flow with minimal downtime

Even with regularly scheduled maintenance, equipment can fail without warning, causing costly and time-consuming breakdowns that congest platforms and frustrate passengers. Intelligent connectivity makes it possible to integrate systems and deploy smart sensors to monitor vehicles, equipment, and infrastructure, in real-time.

This proactive maintenance approach not only minimises downtime but also helps extend asset lifecycles for a longer, better return on investment. Smart monitoring has applications beyond maintenance that enhances every aspect of transit operations. It can be used to connect transit control, maintenance management facilities and vehicles to generate comprehensive real-time operational insights to keep things running smoothly.

In Tokyo, Internet of Things (IoT) sensors are combined with advanced data analytics to help identify weaknesses, forecast failures and schedules repairs – to keep its 34 million weekly passengers moving around the city. This use of ‘condition-based maintenance’ reduces the need for maintenance-related closures and allows the operators to pivot from inefficient periodical maintenance system to intelligent scheduling.

Sustainable environmentally and financially

System-wide connectivity also gives transit authorities new tools to manage environmental impacts while controlling costs and boosting ridership. Sensors to monitor passenger counts in stations and on vehicles make it possible to adjust temperature controls dynamically — conserving energy while improving passenger comfort. The greener, cleaner, and more comfortable the rider experience, the more it will appeal to passengers. Barcelona is capitalising on this trend with a city-wide smart strategy that includes hybrid buses and smart bus shelters with solar-powered digital screens that show waiting times.

Smart technologies can also help make system operations more financially sustainable. The legacy approach of investing in one-off ‘point’ solutions often ends up requiring duplicate, parallel technology infrastructures or equipment for individual capabilities, adding costs instead of streamlining. Using a converged network enables multiple applications at once, creating opportunities to consolidate infrastructure and gain long-term efficiencies.

Leveraging anonymised aggregated data gathered from the network can help transit authorities plan more effectively for the future by correlating ridership trends, fare revenue, operational expenses, and hardware depreciation. This helps operators gain an integrated, accurate, predictive picture of where investments will deliver the biggest returns to improve system performance and passenger experience.

The good news is that many transit authorities already have the building blocks for this future transit vision through their deployments of wireless network technologies. The opportunity now is to turn those building blocks into a sustainable platform for evolution.

In our next blogs, we will delve further into how ‘transit of the future’ can improve the passenger experience, digitising transit operations and mobility as a service.

Transit of the future: deliver the data-driven experience passengers expect

Passengers increasingly expect connectivity to keep them informed, productive and in touch with family and friends throughout their public transit journeys.

As smart communities evolve around transit systems, this expectation will only rise. Driving increasing demand for value-added services or applications that make the passenger experience safer, more comfortable, and more enjoyable from start to finish.

One of the most important benefits connectivity across transit networks offers is safety. The COVID-19 pandemic has heightened expectations that services should proactively protect people’s wellbeing. In an environment as dynamic and fluid as public transit, passengers want (and expect) to receive updates in real-time. Including notifications related to trip delays, security incidents and other shifting conditions, with clear guidance on what they should do next.

How does a transit authority meet those expectations? Having the right network in place is key. With intelligent connectivity, sensors and insights-driven data analytics, transit authorities can push real-time alerts directly to passengers’ mobile devices. Helping them make informed decisions to avoid overcrowded stations and/or plan alternate routes.

People want to stay connected

With smartphones being a cornerstone feature of modern life, people expect to stay connected everywhere they go. Transit systems that offer public Wi-Fi can help meet that expectation with their existing networks. Having the supporting platform already in place makes it easy to integrate add on ‘connected capabilities’ to enrich the passenger experience.

Take ticketing, for example. A mobile app can help passengers calculate fares accurately for a route on the spot, improving trip planning. Smart biometric barriers could eliminate the need for swipe cards, tickets or tokens, allowing passengers to move seamlessly through stations and board vehicles, with fares deducted automatically through Wi-Fi.

Beyond the point of payment, transit authorities in Auckland, London, Paris and Calgary are experimenting with — or have implemented — zone-based pricing. With the use of digital connectivity, they can adjust fares automatically according to time of day, distance travelled or other parameters. This not only provides an opportunity to boost revenues in peak periods but also to stimulate ridership and optimise usage patterns by incentivizing off-peak or alternate route travel. Applying data analytics to monitor flows would allow authorities to fine-tune consistently the movement of passengers through the system — and enhance the passenger experience at the same time.

Connectivity also enables digital and interactive help points, on-board vehicles or in stations, that can update in real-time to deliver responsive navigational information to passengers. In Barcelona, for example, interactive billboards and signage keep riders current on timetable changes and congestion. This same connectivity is leveraged during emergency situations, where their operations teams synchronize signage with in-station lighting to facilitate passenger way-finding.

In Vienna, where the transit system has the reputation of being among the world’s best. Authorities use multi-sensory guidance systems, out-of-order notices and custom-designed route planners to help people with hearing and visual impairments navigate the transit system easily.

Protecting passenger privacy

While there are rich opportunities to leverage passenger data to enhance the commuting experience, transit authorities need to implement safeguards to protect their riders’ information. Adherence to privacy legislation, such as the European Union’s General Data Protection Regulation (GDPR), is critical.

Fortunately, the value in transit network data can be gained from anonymized device associations that do not contain any personally identifiable information. The Connectivity outlook report 2020 found that 80 per cent of passengers are comfortable with transit authorities using their data anonymously to improve the transit experience.

With anonymized device data, transit authorities can help passengers monitor their preferred routes for service changes or nudge them toward alternate routes when volumes are high. In Toronto, authorities implemented an application that leverages this type of data to optimize passenger flows and identify overcrowding before conditions become hazardous. In the wake of the COVID-19 pandemic, this solution was quickly adapted to facilitate safe social distancing protocols on station platforms.

Ready for growth

Tapping into the enhanced data insights of authorities’ networks can shift to a proactive transit planning approach, enabling the most efficient use of resources. This is going to become increasingly important as cities continue to grow — and from New Delhi to Dhaka, that’s the forecast for many years to come. By 2050, the United Nations estimates nearly 70 per cent of the world’s population will in cities — up from 55 per cent today. As urban planners think about increasing demands on their infrastructure, transit authorities can leverage insights derived from their transit networks to support planning efforts and position themselves to meet passengers’ evolving expectations.

Transit of the future: How can data optimise your operations?

In smart communities of the future stations and vehicles will be more than just physical assets.

They’ll connect smart hubs that make operations run smoother and elevate the passenger experience, supporting a vast range of applications. From real-time monitoring and onboard predictive maintenance to energy efficiency and temperature control.

Vehicles need continuous connectivity to support these kinds of applications. With a combination of cellular and Wi-Fi networks, connectivity can be provided through various technologies, such as outdoor macro cell sites, small cells, in-station and trackside coverage networks — augmented by onboard and in-station Wi-Fi networks. With that seamless connectivity, every vehicle becomes a moving data hub able to exchange a rich set of real-time information about its location and speed, physical condition, passenger load and other attributes sourced from the sensors embedded throughout.

Every vehicle is a hub

Uninterrupted connectivity will transform every vehicle in the fleet into a rolling digital hub. Opening up a wealth of insights to operations teams by providing live monitoring of a vehicle’s status and alarms, as well as longer-term perspectives that can convert into actionable insights.

Terabytes of vehicle status data, stored in the cloud, could provide a basis for long-term historical analysis and predictive maintenance algorithms. Triggering alerts about wear and tear on brakes, doors and other equipment before outright failures occur. Vehicle data such as axle temperature, vibration and alignment could correlate with factors like equipment age and external information sources, such as weather reports, to further predict equipment reliability for efficient maintenance and spares management.

All this data could also support service planning. Knowing the total passenger weight of any single car, line or entire transit network, for example, would make it possible to understand accurately service demand on any day. Combined with population growth and density projections, this would give route planners a greater ability to identify and plan for seasonal variations in passenger volumes. Providing them with greater insights for adjusting fares, schedules, or capacity to increase overall efficiency.

Additional applications could include integrated environmental sensors, smart ticketing and online fare payments to allow passengers to get on and off any vehicle without passing through physical bottlenecks, such as turnstiles. Live data feeds can push notifications to mobile devices or to onboard messaging systems so passengers can adjust their route choices on the go; helping operations teams better manage everyday congestion and guide passengers in case of emergencies. Similarly, traffic volume and condition data can go directly to in-station help points for passenger way-finding and decision making.

And of course, there’s the matter of connecting passengers themselves. Onboard live TV, news and Wi-Fi access all rely on the highest-quality mobile connectivity.

In Hong Kong, BAI is using innovations like these to support fully automatic and driverless trains on the Mass Transit Railway’s (MTR) South Island Line. BAI‘s communications infrastructure provides real-time video surveillance of the track ahead as well as the carriages themselves, feeding directly into the MTR’s control centre. With smoke alarms, closed-circuit TV (CCTV) connected, the train’s alarm system automatically scans its surroundings to provide operations teams with live footage of the area. Connectivity also supports the onboard helpline system for passengers.

In partnership with BAI, the MTR has begun a project to upgrade its train-to-ground networks across the entire system. The upgrade will provide higher data throughput between trains and the core network. This will support more extensive and higher resolution in-train CCTV and will provide connectivity for train-borne infotainment, train status data offload, alarms reporting, and passenger Wi-Fi services.

Every station is a node

Connecting key assets to the network — such as doors, elevators, and temperature control systems — presents operations teams with many opportunities to both increase efficiencies and improve the passenger experience.

Smart CCTV provides safety teams with a more detailed view of platform conditions across the system and alerts operations to crowding or congestion issues. It can also help passengers identify lost items or alert security staff to potential hazards concealed in unattended bags. It’s even possible to deploy ambient noise sensors that ‘listen’ for abnormal sounds to identify dangerous situations quicker.

In addition, passenger comfort can be controlled through smart air quality and environmental sensors that trigger heating and cooling dynamically, depending on the conditions of each site. Helping authorities save energy and realise long-term cost efficiencies.

Combining vehicles and stations into a transit system network

With passengers, vehicles, and assets connected to each other, interactional, anonymised data gives transit authorities a comprehensive, real-time view of their operations and performance — as well as the ability to control and adjust systems as required.

This was precisely the case in Milan, where the local authority, Azienda Trasporti Milanesi (ATM), increased passenger safety by transforming its various disjointed solutions into a single converged IP network. The network has allowed ATM to install CCTV cameras throughout its underground metro lines to provide better coverage and enhance passenger safety. The centralised architecture has allowed ATM to cut costs and streamline its operations – requiring fewer technicians to carry out routine maintenance across the system.

By integrating operational and passenger-facing solutions onto a single platform, with analytics delivering comprehensive insights, authorities reduce short and long-term costs and can reinvest those savings elsewhere for even greater impact. Investing in converged connectivity will allow transit authorities to meet the growing demand for transit services in a way that’s flexible, integrated, and economically sustainable.

By connecting stations and vehicles together in an end-to-end transit network, transit authorities can make the entire system more efficient, cost-effective and higher performing than ever before.
