Intelligent Transport Systems
Trucks that sense when to increase or decrease speed and street lighting that comes on when a car approaches. Intelligent transport systems and ICT with wireless communication has numerous benefits. Perhaps soon you’ll even be able to catch a bus without a driver.
Today sensors are everywhere. They collect large quantities of data – data from which society and industry can derive benefit. Time, energy and money can be saved. Wireless communication enables the information from the sensors to be collected and used in new ways. In ordinary cars it saves fuel and provides a safer traffic situation.
Intelligent transport systems are a newly established priority area within KTH EE. We are also developing new technology for more fuel-efficient hybrid cars powered by hydrogen gas, which can deliver higher efficiency than internal combustion engines, as well as electric roads.

Examples of research
- Long-distance trucks in convoy is a project that is being conducted in collaboration with Scania. Wireless communication and sensors in the infrastructure and in the lorries transmit information in real time enabling the lorry’s system to regulate when it is time to start, increase or decrease speed and stop. The system judges the distance to the vehicles in front and behind, and senses when a hill is approaching or traffic lights are about to change to red or green. Further reading is available in the article “ ”.
- Automated road lighting. Imagine what a saving in energy and costs we would make if the lighting on streets and in road tunnels only came on when a vehicle was approaching. Today our street lights and tunnels are lit whether there is a vehicle there or not. Just as the lighting in a room is switched on by a sensor when we cross the threshold, researchers are developing techniques to enable this to become reality in traffic.
