The New Zealand experience in restructuring road administration New Zealand road reform

Reform in the public sector in New Zealand saw the abolition of the Ministry of Works and Development in 1988, with the commercial activities being transferred into a Government owned company. Further reform saw the client function of roads transferred initially into the Ministry of Transport and then into an independent Crown agency known as Transit New Zealand. Transit New Zealand is led by an Authority of six members, appointed by the Government, and it administers the strategic (national) road network (10,500 kilometres).In 1996 a separate funding body, Transfund New Zealand, was established to distribute funds to Transit New Zealand and local authorities. Transfund New Zealand is funded through a share of the petrol excise, all vehicle registration and licensing fees and all road user charges (an axle-weight/distance charge levied on diesel vehicles, especially trucks). These revenues are paid into a dedicated National Roads Fund, which allows a measure of transparency in funding the road system. The reforms in New Zealand have resulted in large efficiency gains, with no measurable lowering in level of service.The road agency of the future is discussed, along with possible changes in road management.

A NEW URBAN FORM AND ITS INNOVATIVE TRANSPORTATION STRATEGY TO ACCOMMODATE URBAN GROWTH

If we are to accommodate the rate of urban growth which North America will face in the first half of the twenty-first century, it is the contention of this paper that we must build new cities, not new towns, beyond commuting distance of existing cities. These can be located in open countryside on virgin land, or they can grow around existing small towns, all in conjunction with the construction of an innovative personal transportation system. In this paper a hexagonal modular structure, in which self-contained urban units can be combined and added to over time, is proposed as a new urban form and AVCS maglev — which will serve the new cities efficiently — is proposed as a key transportation strategy.
