3.7 Intelligent Transport System (ITS)

Transport policy measure (TPM)

Deployment of roadside-based ITS infrastructure for information services (provision of warnings and dynamic speed harmonisation)

Description of TPM

The increasing demand for mobility (both people and goods), the environmental problems and road safety require a high performance road transport system where drivers, vehicles and infrastructure are integrated into one reliable, efficient and smart transport system. Theseobjectives can be realised by services and systems supported by an integrated approach of intelligent vehicles and intelligent infrastructure supporting the driver. These intelligent systems and the interaction between vehicles and roadside are today enabled by advanced information and communication technologies.
These services/systems are dealing with:
• Up-to-date traffic information, traffic management, congestion reduction, improved mobility
• Increased road safety and security,
• Reduction of environmental problems,
• Development of sustainability.
The intelligent infrastructure is the key component in the support, management and interaction between the drivers/vehicles and the network operator. [1,2,4]

Implementation examples

- SMART highway R&D project, launched in 2008, Korea
- Harbin, China: autonomous road side infrastructure based system

Objectives of TPM

- Reduce congestion
- Avoid accidents
- Increase road safety and security
- Reduce environmental problems [2,4]

Choice of transport mode / Multimodality

Origin and/or destination of trip

Trip frequency

Choice of route

Timing (day, hour)

Occupancy rate / Loading factor

Energy efficiency / Energy usage

Increase in energy efficiency due to traffic management and increased free flow of road vehicles.

Implementation phase

The works during the implementation may affect traffic badly up to a very limited level.

Operation phase

See below

Summary / comments concerning the main impacts

The measure mainly influences traffic addressing the following elements through the management of traffic: reduction of congestion (also reduction of transport time), avoiding accidents (improvement of safety, improvement of mobility). [4]

Overall impacts on social groups

Implementation phase

Implementation costs for public bodies is an issue.

Operation phase

Operation costs for public bodies should also be considered.

Summary / comments concerning the main impacts

The measure has very limited economic impacts, however the system definitely reduces transport costs, accident related costs (health and insurance, because of reduction of accidents) and makes road transport much more competitive. [3]

Summary / comments concerning the main impacts

Roadside based ITS infrastructure helps traffic avoiding extreme situations, congestions, accidents, and other anomalies. These effects make possible to reduce air pollution, noise emission, and climate change, (especially for residents living nearby) while the built infrastructure affects visual quality badly. [3]
