Problems with future provision of freight infrastructure There are 3 types of future growth Problems with future provision of freight infrastructure There are 3 types of future growth that cause problems: Ø unforeseen or exceptionally rapid growth, leading to infrastructure bottlenecks Ø un-(or under-)funded growth, leading to chronic constraints on the networks Ø growth in confined spaces, which leads to congestion on the networks

Unforeseen growth Øcoal ports at the moment Øcurrent throughput is mostly at, or beyond, Unforeseen growth Øcoal ports at the moment Øcurrent throughput is mostly at, or beyond, normal measures of capacity Øunsatisfied demand Øsuch periods not infrequent Øcapacity is eventually expanded

Un-(or under-) funded growth Subject of much of the infrastructure debate currently Ø not Un-(or under-) funded growth Subject of much of the infrastructure debate currently Ø not only freight transport (eg hospitals, technical training, urban rail systems, etc) Ø running down of freight infrastructure or lack of investment in necessary expansion Ø rapid truck growth = more expensive construction costs and more maintenance

Similarly, the run-down rail network will probably need at least ‘restoration’ funding. But bear Similarly, the run-down rail network will probably need at least ‘restoration’ funding. But bear in mind that even if the interstate rail system were rejuvenated and, say, doubled its mode share by 2020. . . national non-bulk road tonne-kms would still double in 20 years vs. more than double without rail rejuvenation

Growth in confined spaces Traffic in our capital cities grew about 40% in last Growth in confined spaces Traffic in our capital cities grew about 40% in last 15 years. This increased traffic was handled in 3 ways: Ø building freeways Ø building intelligence into the road network Ø peak spreading All 3 ways of coping with growth in our cities will start to run out of puff eventually

Øanother 30 per cent growth in traffic expected in the next 15 years – Øanother 30 per cent growth in traffic expected in the next 15 years – same absolute increase Øarticulated truck traffic = almost doubling, but heavy trucks a small part of the traffic stream Øcars and light commercial vehicles = traffic increase. Øcongestion => trucks, not trucks => congestion

Types of freight infrastructure pressure So there are 3 types of growth that present Types of freight infrastructure pressure So there are 3 types of growth that present problems for freight infrastructure provision : Ø rapid and/or unforeseen growth Ø un-(or under-) funded growth Ø growth in the confined spaces of our cities None of these pose insoluble problems Some major shifts in policy and planning may be required
