Three specific research areas are studied: ll} to describe the process of urban transport planning as it operated in Christchurch; (.2)_ to identify the nature of the relationship between transport and urban development in Christchurch; and (3} to assess how this relationship, and the urban transport planning process has adapted to change during the course of the Master Transport Plan. The study showed that the perception of the decision situation in the Christchurch case was largely subjective but played a major role in the decision-making process. A 'rational' master planning methodology was inapplicable, incremental planning decision seemed more important to the plan product. CHAPTER I 1 CHAPTER 1 INTRODUCTION The provision and maintenance of an efficient network of transport routes has long been one of the major concerns of city planners. McConnell (1981) cites the co-ordination of the use of urban spaces and the channels of movement as 11 ... a functional reason for planning. 111 Indeed with the modern urban form being a 11 ... concentration of people and activities such that movement and communication among them may be achieved at low overall cost, 11 2 the need for efficient linkages is paramount, and the role of the transport planner crucial. Modern prescriptive urban planning has indeed recognised this. The concept of the city as an 'urban system', with transport as the link between this system's component parts, has been a common theme in planning literature.3 The most frequently used analogy in this respect is that of the city as an organic complex. 4 Wheeler (1974) went so far as to describe the city as an 'urban corpus' within which the transport network acts similarly to the human vascular system. 5 Such an analogy serves to highlight the role transport plays within the urban complex. Study Aims This thesis attempts to examine the place of transportation planning within the broader tapestry of planned urban development in the Christchurch 1. McConnell (1981) p.3. 2.

The aims are threefold: (1) To describe the attempts of a range of public bodies to co-ordinate the process of transport planning within the Christchurch metropolitan area. (2) · To identify the nature of the relationship between the forces of transport and development in the Christchurch case, over time, and (3) To assess the manne~ in which both this relationship and the urban transport planning process itself has changed and how these changes have been articulated in Christchurch. This thesis is concerned primarily with the evolution of a Master Transportation Plan for Christchurch (M.T.P.). In this respect attention is concentrated upon urban transportation planning in the period from the 1950's to the 1970's. Thesis Structure Urban transportation planning has been described as "The appraisal of conditions within the community (leading to) a choice among alternative actions within government and the alleviation of unsatisfactory conditions through the implementation of a chosen action, 11 6 - it therefore involves decision-making in the selection of a strategic choi.ce. Such a process can be represented diagrammatically as below (Figure 1.1). 6. Hutchison (1974} p.6. 3 Situation ------Change COMMUNITY SUBSYSTEM GOVERNMENTAL SUBSYSTEM Perception of choice of Decision Field Action Formulation and Comparison of Possible Actions Adapted from: Friend and Jessop (196 9 ) p . 104 . Figure 1.1 Urban Transport Planning Process This circuit involves interaction between the governmental subsystem, where such strategic choices are generally made, and the coITTnunity itself, where the 'choice' would be applied. Information and influence are passed between these two subsystems. For example, a persistent state of congestion in a road network calls for a response from concerned governmental bodies. Their decision - whether it be to 4 act in a certain manner or not act at all to alleviate the problem - has its effects felt back in the community subsystem. The process of selecting the type of response involves therefore the making of decisions, based on available information. It is to how this process has operated and the results achieved in terms of Christchurch urban transport planning that this thesis is addressed. The remainder of this Chapter provides an introduction to the general aspects of master transportation planning methodologies, after which the study begins to examine how the various elements of the model introduced above were articulated in Christchurch. The first element - perception of the decision field - involves the development of the initial understanding amongst concerned public bodies of the type of transport problem they were confronted with. Faludi 7 has argued that such perceptions or 'definitions of the decision situation' are subjective, thus influencing the range of choices available. Whether this is the case in Christchurch will be determined by analysing the evolution of the problem and the call for a planning response (Chapter 2). The type of response selected is a product of the subjective perceptions outlined above. The formulation and comparison of alternative courses of action, the changes in the exogenous planning and political environments and the choice selected as the M.T.P. 'solution' are described in the third chapter. Since the planning process itself is not 'immediate' - solutions to transport problems are generally not developed and produced instantaneously, but rather evolve over some time - then conditions in the environment in which such a process operates may themselves change. Chapters 4 and 5 examine this period of 'lag' between M.T.P.
