Smart Transportation and IoT


Srinidhi Murthy

Thanks to laptops and smartphones, human beings are able to stay connected to the Internet more often that ever before, but yet there are still some notable dead spots, particularly in cars, buses, and trains. Anyone with a daily commute can speak to lapses in coverage on the subway or when going through a tunnel.

But the Internet of Things is looking to change all that and keep people connected at every moment of every day. Connected cars, buses, trains, and even planes will allow people to have a stable Internet connection at almost all times.

And the transformation won’t stop there, as the IoT will make transportation itself more efficient and help us get from place to place more quickly.

A new term called as “Internet of Transportation” has been coined and it will create the new era of connected transportation and change how we travel.

With Internet of Transportation assets we can:

  • Reduce congestion by monitoring and controlling traffic lights.
  • Send alerts to drivers and emergency responders on trip conditions, then offer alternative routes.
  • Reduce fuel consumption and vehicle emissions.
  • Provide smart parking solutions that identify and communicate available spaces.
  • Improve safety for motorists, pedestrians, and bicyclists.
  • Identify structural issues of bridges, roadways, and tunnels.
  • Provide smart lighting and security monitoring for city streets.

Let’s look at some of the use cases of Smart Transportation and how they are implemented.

Fleet Management:
Fleet telematics solutions help businesses, transportation carriers, and governments improve economics, safety, and compliance by intelligently monitoring and controlling their vehicles.

Specific or Generic Smart Applications gather and analyze data from on-board instrumentation and GPS sensors to track vehicle status and location, optimize routing, and monitor driver and equipment performance and productivity.

Connected Cars:

In the last few years, connected cars or smart cars have surged in popularity thanks to the IoT. Today, car companies are connecting their vehicles in two manners: embedded and tethered. Embedded cars employ a built-in antenna and chipset, while tethered connections make use of hardware to let drivers connect to their cars through their smartphones.

On top of this, app integration is becoming more and more standard in the car of today. Google Maps and other navigation systems have started to replace built-in GPS systems in dashboards.

Apps such as GasBuddy show the driver where he or she can locate the cheapest fuel in their area. And music apps such as Spotify have started to away the need for traditional and satellite radio.

Transport Logistics:


Intelligent transport logistics solutions help long-haul cargo operators and last-mile delivery providers efficiently manage the transportation and distribution of freight and merchandise.

Smart applications gather and analyze data from onboard sensors to track containers and packages, and to monitor environmental conditions, ensuring goods arrive on time, at the right place, intact.

Traffic and Parking Management:



Integrated Traffic and Parking Management Systems can reduce congestion and save fuel in Business Districts and City Centers. Sensors built into Parking Meters can indicate to a server when a parking slot becomes available. A car User with a Smart Phone App can request to find a parking space within a designated radius based on the GPS location and the server responds with the available parking spaces. This saves fuel and congestion caused by Simply using visual parking search methods.

Traffic Management systems can use sensors, cameras, to find out intersection that has become congested and Use smart algorithms to determine which direction the traffic needs to be moving too quickly clear congestion. It can also act as an Emergency response systems in case of accidents or emergencies.

Renewable energy business is continuing to grow all over the world as the entire world is looking for clean and alternative energy source to control the pollution.

IOT solutions are helping this business to improve operational excellence, efficiency, cut cost, fix issues proactively, increase productivity and profitability. The effective use of IOT is the differentiator among the competitors. Real-time analytics can make a significant difference to act quickly to identify and fix issues and improve operational excellence. The challenge in the system is the amount of data being collected from the power sources, it is huge. This challenge is common for both wind and solar energy systems where the wind turbines and solar panels are many in number and are spread across various places. As the amount of data being generated is huge from these sources, the cost of sending these data to the cloud and using big data infrastructure are increasing the overall cost of operations. And it impacts the network latency and performance.

Wind energy
In a large Wind energy farm, the IOT system is collecting data from sensors that includes Acceleration, Temperature and Vibration data from turbines. These data need to be collected and analyzed in real-time or near real-time for quick analysis and actionable insights for performance optimization to increase productivity and predictive maintenance to avoid downtime.

The challenge with this IOT system is transferring huge data from various locations in real-time to a central location to run queries on the data and perform analytics. This makes the cost of data transfer much higher than the benefits it is giving.

Solar Energy
In solar energy infrastructures, the essential data that can be collected from the sensors by IOT system includes Irradiance (Solar panel tilt angle), wind factors. Ambient temperature and location. This data can be used for performing analytics, compute predictive algorithm, calculate the energy that is being generated in all the connected solar energy system, analysis of energy generation pattern, Fault/ Problem detection and Real-time visualization of the solar systems. The data need to be collected and analyzed in real-time

Like IOT system for wind energy, the challenge of transferring huge data in real-time to cloud exists in this IOT system also as the size of the data from each Solar unit is huge.

Decentralization – Edge analytics

Decentralization of data storage, processing and analytics can solve the problem of sending huge data to the centralized cloud. Ability to run queries at any given time can be achieved by Edge analytics. The data generated from the solar panels or wind turbines can be filtered at the edge and send only the meaningful data to the cloud to run queries for analytics, this will help to reduce the data transfer cost. Real-time and post-mortem analytics can also be done completely in Edge gateway or with cloud analytics whichever is the best suitable and cost effective for the specific renewable energy use case.

So, the existing challenges in IOT systems of renewable energy can be handled by implementing a decentralized IOT solution with data filtering, processing, and analytics done in Edge side of the IOT solution.
