Urban Mobility and the Future of Smart Transportation

Cities are overcoming congestion and increasing mobility with smart city Internet of Things (IoT) technologies.

Urban Mobility Takeaways

  • The pressures of growing populations; increasing vehicle volume; and aging, physically constrained transportation infrastructure are creating urban gridlock that impacts productivity, public safety, and public health.

  • Cities are using smart city technologies to improve traffic flow and public safety on existing roadways and extracting insight that is informing traffic engineering and infrastructure improvements.

  • Intelligent transportation systems, open data frameworks, and AI-assisted applications are transforming urban driving into on-demand Mobility as a Service (MaaS) that is helping reduce congestion and increase mobility.


Smart city technologies and intelligent transportation systems are helping cities absorb growing populations, overcome congestion, and create sustainable futures.

What Is Urban Mobility?

At its core, urban mobility is about how people and goods move through a city. It seems simple, but as you consider all factors—infrastructure, technology, politics, culture—how we navigate cities is a complex subject with an ancient history and an increasingly sophisticated technology-fueled future.

Urban Mobility Challenges

The fundamental challenges of getting around a city have been with us since humans began living in urban environments. How do we balance congestion, ease of movement, and pollution?

The tensions between innovation in transportation, constantly growing urban populations, and civic government’s ability to keep up with limited resources are timeless. But the pressure today’s cities face is unprecedented.

Urban population growth will continue to strain urban mobility:

  • 4.6 billion city dwellers by 20251
  • 41 megacities by 20302
  • 67.1 trillion passenger kilometers on mass transit by 20502

Time spent sitting in traffic is a major drain for individual commuters and the overall productivity of the world’s cities. According to a 2019 Global Traffic Scorecard from INRIX,3 the US lost an average of 99 hours per driver to congestion in 2019, costing nearly USD 88 billion in lost productivity.

Public Safety
Congested roadways do more than waste time. Traffic accidents kill 1.35 million people around the world each year and leave between 20 and 50 million people with nonfatal injuries. More than half of all road traffic deaths and injuries involve pedestrians, cyclists, and motorcyclists and their passengers.

Public Health
Congested stop-and-go traffic increases the volume of microscopic particulates in vehicle exhaust.4 According to the World Health Organization, exhaust particulates are “capable of penetrating deep into lung passageways and entering the bloodstream causing cardiovascular, cerebrovascular, and respiratory impacts.”5

Environmental Impact
Cities everywhere are concerned about environmental sustainability, and transportation is a major contributing factor.

An estimated 22 percent of global carbon dioxide (CO2) emissions are attributed to the transportation sector,6 which will rise as cities grow and individual citizens adopt carbon-burning transportation.

For example, without major investments in public transportation and smart road technologies, CO2 emissions in India are projected to rise from 70 megatons in 2015 to 540 megatons by 2050.7

Meeting Urban Mobility Challenges Today with Smart City Technology

Cities are improving mobility, saving energy, and reducing pollution today with smart city IoT technologies.

Smart cities take in data from every available input—traffic signals, cameras, embedded devices on public transit—then analyze the data with AI and share it through open data pools. This creates a constant awareness of conditions that can be used for traffic management, route planning, public safety, and emergency response.

Smart City Technologies Can Be Embedded Throughout a City’s Infrastructure

  • Smart pavement can monitor weather, road conditions, and even road wear and share the information with drivers and traffic controllers.
  • Smart parking can alert drivers to available spaces, reducing time spent circling and searching for a spot.
  • Smart traffic signals can respond to traffic conditions and retime themselves to relieve congestion.
  • Smart streetlights with cameras, microphones, and sensors can dim themselves when no one is around and gather intelligence on traffic, public safety, and air quality.
  • Smart cameras can keep an eye on traffic and public safety. When problems arise, they automatically alert transportation systems.
  • Smart intersections can optimize vehicle and pedestrian traffic, detect risks, and warn against imminent accidents, reducing crashes and injuries.
  • Smart tolling can assess tolls on free-flowing traffic, support specific road congestion pricing or per-mile tolls, and collect fees electronically.
  • Smart public transportation can count passengers, track vehicle locations, and automatically share status.
  • Smart fleets, including public police vehicles and fire engines plus private delivery trucks, taxis, and trains, share their location, watch over their drivers, and listen to their engines, brakes, and wheels for signs of wear and tear.

Smart traffic systems can save commuters up to 60 hours a year.4

Together, these intelligent sensors, microphones, and cameras can power a model of what’s happening on a city’s streets, highways, and rail lines in near-real time. With the help of AI, this awareness can transform passive traffic management into active intelligent transportation systems.

These systems can anticipate congestion, automatically reroute traffic, retime lights, and apply dynamic tolling to help keep the city moving. The city of Bangkok, Thailand, is saving over 51,000 commuter hours a year and reducing traffic delays up to 24.5 percent with just three smart intersections.8

The Future of Urban Mobility

Multiple technologies are coming online that will fundamentally change how people and goods move through cities. Increasing vehicle intelligence, autonomous systems, and vehicle communications will improve safety, traffic flow, and emissions.

Vehicle Communication and Orchestrated Traffic
Vehicle communications technologies will turn the current state of unpredictable, “dumb” vehicles into smart, active players within the smart city’s intelligent transportation system.

Vehicle communication—between individual smart vehicles and from smart vehicles to central traffic management systems—will help traffic flow as an intelligent, unified whole that maintains consistent speeds and set vehicle distances. Throughput and fuel efficiency will increase dramatically as accidents drop and pollution eases.

Researchers in Germany have built an experimental two-kilometer test field on the autobahn that communicates with vehicles and orchestrates traffic. It uses overlapping radar sensors to model traffic in near-real time. The system shares this information with oncoming cars, signaling them when it is safe to change lanes, when to reduce speed, and when to avoid critical situations.8

Smarter, More-Flexible Public Transportation
Bus and rail will continue to be fundamental elements of urban mobility. Incremental technological upgrades, using open platforms consolidated onto standard x86 hardware, can support smart security video, monitor vehicle systems, and deliver AI-powered predictive maintenance.

These platforms can also support better rider experiences by providing Wi-Fi, onboard entertainment, and interactive information displays.

Mobility as a Service (MaaS)
Getting around a city today takes planning and effort, whether you are driving your own car, ride sharing, or navigating public transportation. Smart cities with intelligent transportation systems and open data platforms are changing mobility from a chore into a service.

Commuters today can choose from multiple apps, like Moovit, that can plan routes and schedules across public transit. As cities grow smarter, and the number of autonomous, connected vehicles increases, mobility as a service (MaaS) applications will be able to weave every available transportation option into a seamless, multimodal trip. Commuters will save time while the system optimizes traffic flow, energy efficiency, and vehicle use across the city.

Urban Mobility Technology Requirements

Reaching the highest levels of intelligent transportation and smart, energy-efficient urban mobility requires many, many technologies. Thankfully, upgrading a city is not an all-or-nothing proposition. Many of the technologies are already in place; others only need incremental upgrades. The biggest challenges—privacy, data security, data ownership—lie at the intersection of technology and public policy.

Key Technologies for Upgrading Urban Mobility

Embedded Smart City Devices and Systems
Cities already collect massive amounts of data through existing systems like traffic and public safety cameras. Incremental upgrades can transform them into intelligent nodes in a smart city fabric.

Everywhere AI
To function in near-real time, intelligent transportation systems need immediate insight and analysis. That requires processing AI workloads at the edge, on a smart device itself, or on a nearby AI appliance.

Faster, More-Reliable Connectivity
5G promises to speed cellular data transfer rates and improve stability. Software can help orchestrate and manage edge network services for even better performance.

Open, Integrated Data Pools
Smart city and intelligent transportation data isn’t worth much if citizens, first responders, and businesses can’t access it. Ingesting, cleaning, aggregating, and sharing data through a single shared pool is critical to improving mobility and reducing congestion and pollution.

Hardware-Based Data Security
As intelligent technologies spread and interconnect, cities have to secure thousands of embedded devices and protect public and private data as it moves through the system. Hardware-based security protocols harden systems and help protect data.

Urban Mobility Policies and Standards

Public policies and industry standards are critical for developing smart city technologies for urban mobility and for deploying the IoT technologies that make them possible. Public policy sets the goals and defines the ground rules for the public agencies, private citizens, and businesses that make the city’s vision for a smart, highly mobile community a reality.

  • Open standards so that every smartphone, car, traffic cam, and smart pavement monitor can plug and play with any smart city technology.
  • Open data platforms so that every player has access to the data they need to do their job.
  • Open processes that include all stakeholders so that people buy in and help drive the city’s technological vision.
