Environmental Benefits of Smart City Traffic Management

Awareness of the need for improved sustainability in densely populated urban areas has been greatly heightened in the 21st century, particularly as the information age has enabled mankind to measure quantitative data in relation to the environment.

Furthermore, many cities do not have the ability to add infrastructure and expand horizontally. This can lead to increased levels of traffic congestion, or excessive crowding on public transportation.

That said, the findings from a recent market study by Juniper Research indicate that Smart City traffic management and parking projects will reduce cumulative global emissions by 164 million metric tonnes of CO2 between 2014 and 2019 -- that's equivalent to the annual emissions produced by 35 million vehicles.

Smart City initiatives can benefit the environment, while also positively impacting the quality of city dweller lives. With about 700 million automobiles projected to be on city roads across the globe by 2019, demand for innovative solutions to the challenges of growing communities has advanced.


The Juniper study also found that high levels of city traffic congestion -- combined with advancements in Internet of Things (IoT) sensors and software solutions -- has driven plans to reduce high traffic levels through smart initiatives.

Juniper analysts believe that the establishment of a sensor-networked and monitored city communications infrastructure -- efficiently phasing traffic lights, and providing real-time guidance to drivers -- can aid significantly in reducing urban congestion.

Furthermore, digitally monitored parking spaces able to dynamically alter prices according to available spaces help control time spent cruising for city parking.

Forming a Smart City Ecosystem is Key

Additionally, Juniper found that while purpose-built Smart Cities, such as Masdar and Songdo, can be considered a technological success, the benefits have not yet been fully realized owing to lack of citizen participation.

"Cooperation between all parties, as we have seen in Amsterdam for example, is essential," said Steffen Sorrell, research analyst at Juniper Research. "Furthermore, cities need standards and open data to avoid information roadblocks."

Other key findings from the study include:
  • Smart grids will dramatically reduce energy consumption in cities through rapid smart meter deployment and intelligent distribution automation.
  • Smart street lighting is also expected to produce significant cost savings, aided by the fall in LED fixture costs. Smart networked control systems will further add value.

IoT Device Management Demand Gains Momentum

More forward-thinking CIOs and CTOs are focused on the adoption of the Internet of Things (IoT). Management challenges are top of mind for those who have already deployed a large number of sensors and associated network edge devices. Device management services are evolving in response to a greater breadth of new device technologies such as edge intelligence and related connectivity solutions, as well as the customer scalability and security of IoT deployments. But forward-looking suppliers are also preparing for a world where 41.3 percent of the connected devices will be using some form of Low Power Wide Area (LPWA) technologies by 2026. IoT Device Management Market Development Since IoT customers increasingly need to manage a larger fleet of connected devices, ABI Research now forecasts that IoT device management services will exceed $36.8 billion in revenues by 2026. Standardization is beginning to play a bigger role in device management services, as more connected devices use LPWA t

Anywhere, Anytime Workplace Demand for SASE

The ongoing adoption of flexible working models within the enterprise market has significant implications for typical IT organizations that must now support knowledge workers and front-line employees that operate outside the corporate network perimeter. The global COVID-19 pandemic created IT networking and security challenges. The expansion of the distributed workforce, an increasing reliance on cloud computing infrastructure, and the requirement to securely connect online employees -- wherever they choose to work, at any given moment in time. Legacy IT solutions that have rigid network underlays and a requirement for on-premises infrastructure cannot adequately deal with these trends. This 'Anywhere, Anytime Workplace' led to demand for new Secure Access Service Edge (SASE) solutions, with networking and security delivered as-a-service. Anywhere, Anytime Workplace Market Development   Although converging networking and security capabilities offer enterprises a promising solut

Cloud Edge Computing Demand Continues to Grow

Public cloud computing solutions are moving closer to the edge of networks where CIOs and CTOs are hosting new apps. The edge journey is well underway for forward-looking organizations as they seek to connect with customers, improve operational efficiency, and adopt digital business technologies to drive innovation. The latest worldwide market study by International Data Corporation (IDC) found that three-quarters of organizations plan to increase their edge computing spending over the next two years with an average increase of 37 percent. A combination of factors is driving this increased spending at the edge. Cloud Edge Computing Market Development The performance requirements of expanding workloads and new use cases that leverage artificial intelligence (AI) and machine learning (ML) demand greater compute capacity at the edge. In addition, the amount of data being stored in edge locations are rapidly expanding, and organizations plan to keep this data longer. As a result, the numbe
