What are Intelligent Transport Systems?
ITS is the umbrella term for technology that makes road transport safer, more efficient and more sustainable without building new roads. Instead of adding capacity with asphalt, ITS uses information: where traffic is, how fast it moves, which vehicles are on the road and what is about to happen.
An ITS installation always combines four layers: equipment in the field, a communication network, central software that turns data into decisions, and services for operators, road users or other systems.
The building blocks of an ITS system
- Field equipment: traffic signal controllers, detection (inductive loops, radar, video, thermal cameras), weigh-in-motion sensors, ANPR cameras, variable message signs and parking sensors.
- Communication: fibre, mobile networks (4G/5G), LoRaWAN for low-power sensors and short-range radio for vehicle-to-infrastructure (V2X) messages.
- Central systems: traffic management platforms, urban traffic control, enforcement back-offices and data platforms.
- Services and data exchange: dashboards, travel information, open data and interfaces to other operators, for example in DATEX II.
Main application areas
- Traffic signal control and corridor management in cities.
- Traffic management and incident management on motorways and regional roads.
- Freight: weigh-in-motion, overload enforcement and protection of bridges and pavements.
- Road safety and enforcement: section control, speed and red-light cameras, safer school streets.
- Smart mobility: parking guidance, access control, EV charging and mobility hubs.
- Cooperative ITS (C-ITS), in which vehicles and infrastructure exchange data directly.
Standards and the European framework
Interoperability is what keeps an ITS investment useful for decades. Open standards such as DATEX II for traffic data, NTCIP, OCIT and UTMC for communication between centres and field equipment, and OCPI for charging infrastructure make it possible to combine equipment from different manufacturers and to replace parts without starting over.
In the European Union, the ITS Directive (2010/40/EU, revised in 2023) and its delegated regulations set rules for data availability, for example the publication of road and traffic data through National Access Points. Many ITS installations are also part of essential or important services under the NIS2 Directive, which brings cybersecurity obligations.
From study to long-term operation
A successful ITS project follows a lifecycle: a study or feasibility phase to define the need, design and specifications, procurement, installation and integration, testing and commissioning, and finally operation and maintenance. Decisions made early — open interfaces, a clear data model, maintainable equipment — determine the cost and flexibility of the system for many years.
Planning an ITS investment
- Start from the policy goal — safety, reliability of public transport, freight, air quality — and translate it into measurable functional requirements.
- Take stock of what already exists: equipment, networks, software, contracts and data. Reusing what works is often cheaper than replacing it.
- Specify functions and open interfaces rather than brands, so that several suppliers can compete and the system can grow later.
- Plan operation from day one: who monitors the system, who maintains it, which service levels apply and how performance is reported.
- Include cybersecurity, data protection and accessibility as requirements, not as afterthoughts.
Common pitfalls
- Closed systems that only one supplier can extend or maintain.
- Data that is collected but never used, because nobody owns the analysis.
- Projects that end at commissioning, without budget for maintenance and updates.
- Separate systems for signals, parking and enforcement that cannot exchange information.
