Invensys Rail Group. November 2007.

Over the last 10 years road traffic, in vehicle km, has increased by 1.5% p.a. and demand for road space has also increased. It is projected that traffic levels will increase 1.4% p.a. between 2000 and 2025.Demand for rail has increased in recent years. Passenger demand is predicted to increase by 2.7% p.a. by 2014. However this could even be higher and Network Rail in its recent Strategic Business Plan has suggested that growth could be as high as 6-7%. Rail capacity needs to be increased, both in order to meet current demand levels, and in order to meet future demand growth.
