Information & communication technologies - panacea for traffic congestion?

As road pricing, telematics and logistics evolve, information and communication technologies (ICT) aim directly at making traffic flow more efficiently in a given infrastructure. Furthermore, the virtual world gives rise to new business fields and decentralised structures which affect the development of transport indirectly. While technological progress continues to drive qualitative improvements in traffic conditions, e-business and telework in particular have, for structural reasons, a much less pronounced effect on traffic than widely presumed. ICT helps in organising traffic flows more efficiently and plays a supplementary role as transport-relevant instrument, but it is not a panacea for traffic congestion.
