Dynamic traffic management for sustainable mobility!

What is the correlation between urban traffic and the quality of urban life?


Urban population growth, congestion of urban traffic and pollution are correlations that give rise to unpleasant projections!

The UN estimates that more than 70% of the population on land will live in cities in 2050. In European countries, according to Eurostat, it is already 72% of the population on average that is urban!

At the same time, according to INRIX calculations, traffic congestion is a global phenomenon which has averaged 9% of driving time in 2016. According to their ranking, for Parisian drivers for example, this represented 65.3 hours in the corks in 2016.

Correspondingly, according to the European Environment Agency, air pollution causes 403 000 premature deaths in Europe per year, 50% of which are due to motor vehicle traffic (EEA).

Before going any further, let’s look at Wikipedia’s definition of sustainable mobility: “The notion of eco-mobility or sustainable mobility is a recent concept that emerged after the crises of energy and global warming climate change, in the wake of sustainable development issues. It combines the design, implementation and management of modes of transport deemed to be less harmful to the environment, safe and sober, in particular with a lower contribution to greenhouse gas emissions “

Smart mobility for environmental preservation


In the light of these findings, the European Union has set itself the overall objective of reducing the environmental impact of transport in Europe by reducing 80 to 95% of greenhouse gas emissions by 2050 (EEA).

Together, the “Assises de la Mobility”, launched by the French government on September 19, 2017 in Paris, invite companies, local authorities, associations and the general public to reflect and co-construct changes in transport, by 2030.

In a context where all our resources are limited, optimizing the use of infrastructures rather than building new ones is undoubtedly an essential lever. Technologies for smart management of transport networks exist and have been proven for several decades now.

They represent a key link in the optimization of the use of transport infrastructures, which undoubtedly contributes to reducing the environmental impact. In urban areas, dynamic traffic regulation clearly contributes to the transition to sustainable mobility by streamlining traffic, optimizing priorities for public transport, reducing pollutant emissions and contributing to noise reduction in cities.

IoT offers solutions that deserve more attention


Among many relevant measures, such as encouraging carpooling, the use of soft modes, the transition to electromobility; in order to better exploit and sustain the existing road infrastructure, real-time traffic regulation proves that it is in many ways a key option with a significant impact.

Today’s technological advances offer the power and agility of wireless vehicle detection systems, which are useful for informed decision-making, optimal traffic management and the operation of related infrastructure, or to inform automated traffic control processes.

Specifically, smart sensors, embedded in the roadway, detect the vehicles by measuring the earth’s magnetic field variation and, in real time, transmit the necessary data to PLCs for field equipment for the dynamic control of the flows on the road network.

Thanks to these systems, it is possible to act quickly on many levers:

  • Facilitate the local management of traffic junctions,
  • Improve the flow of traffic on the road network,
  • Implement strategies for coordinating neighborhood and city-level traffic lights,
  • Manage priorities for public transport.

Wireless Vehicle Detection Systems for Sustainable Mobility


The interest of miniature wireless sensors lies in their minimal invasion of the infrastructure as well as in their energy autonomy but also in their onboard computing capacity and their synchronization mechanism for the real-time ascent of useful data, to the control automation of the traffic lights or to the central control unit.

Here is the core of advanced traffic control systems!

Based on robust radio networks with urban interference, broadband, low power consumption and extended range, such as those implemented by HIKOB, wireless vehicle detection systems guarantee the transmission in real time of an unprecedented quantity and accuracy of information to interact directly in the field with the equipment (light controller, PMV, etc.) or to feed the calculation algorithms of the central PC.

It is this continuous, centralized and remote access to crucial information, distributed locally, which allows a fine and dynamic control of the simplest intersection, the most complex crossroads, a set of crossroads on a scale of a neighborhood up to the management of the entire city junctions.

Wireless technologies are driving real-time traffic control into an unparalleled level of service and intelligence to optimize the operation of road networks and induce:

Direct benefits:

Smart mobility

  • reduced travel times
  • Fluidification of urban traffic
  • Improved driving comfort
  • Securing traffic

Indirect improvements:

A best-preserved environment

  • Increased air quality
  • Reduction of noise

A fostered economy

  • Control of operating costs
  • Reduced transportation costs
  • Easy access to city services

Combined with other measures, the urban traffic management in real time is undoubtedly contributing to meet the challenges of the city, as of now and for the future.
