In several years we will need to rely on something other than fossil fuels for our transport needs. One possible alternative is for our vehicles to run on electricity supplied along the road. In autumn 2014, VTI partnered with the Swedish Transport Administration and Viktoria Swedish ICT to test...
A limited pilot study conducted at VTI shows that engine heating is more fuel efficient via coolant than via lubricant. Cold starting a motor vehicle results in higher fuel consumption and more emissions than if the engine is started when hot. Engines have traditionally been pre-heated by...
Most tunnels rely on a complex web of power cables feeding electricity from distant energy sources to power light fixtures mounted in the ceiling. At the same time the tunnels are surrounded by daylight. A new pilot project at the Norwegian Public Roads Administration (NPRA) aims to challenge this...
The Norwegian Parliaments target to reduce new passenger vehicles average CO2-emission to 85 g/km (type-approval value) in 2020, can be achieved by reforms in the vehicle registration tax. In three out of four scenarios, described in this report from Institute of Transport Economics, the...
