Intelligent transportation systems

Sensors and data manage traffic and tolling.

In depth

ITS applies sensors, communications and analytics to manage traffic: adaptive signals, variable message signs, ramp metering, electronic tolling, incident detection and connected vehicles. Improves safety and capacity without new roads. Data privacy and cybersecurity are concerns.

Key points

  • V2X communication
  • Dynamic pricing
  • Smart parking
Example

Ramp meters on freeways smooth merging and increase throughput.

Why it matters

Intelligent transport systems use sensors and data to manage traffic, so they can reduce congestion and improve safety at lower cost than new roads.

Where this is used

  • Adjusting signal timings in response to live traffic data.
  • Charging road users dynamically through electronic tolling.
  • Warning drivers of incidents with variable message signs.

Frequently asked questions

What is Intelligent transportation systems?

Sensors and data manage traffic and tolling.

Why is it important to understand intelligent transportation systems?

Intelligent transport systems use sensors and data to manage traffic, so they can reduce congestion and improve safety at lower cost than new roads.

What do ITS systems use?

Sensors, cameras, communications and control systems that gather data and act on it in real time.

What are the risks of ITS?

Reliance on technology, cyber security, privacy of data, and the need for maintenance of the equipment.

How is Intelligent transportation systems used in practice?

Typical applications include adjusting signal timings in response to live traffic data, charging road users dynamically through electronic tolling and warning drivers of incidents with variable message signs.
