Transportation planning

trains use elevated tracks for a portion of the system, known as the Loop, which is in the Chicago Loop community area. It is an example of the siting of transportation facilities that results from transportation planning. , Poland Transportation planning, or transport planning, has historically followed the rational planning model of defining goals and objectives, identifying problems, generating alternatives, evaluating alternatives, and developing plans. Other models for planning include rational actor, transit oriented development, satisficing, incremental planning, organizational process, collaborative planning, and political bargaining. Planners are increasingly expected to adopt a multidisciplinary approach, especially due to the rising importance of environmentalism. For example, the use of behavioural psychology to persuade drivers to abandon their automobiles and use public transport instead. The role of the transport planner is shifting from technical analysis to promoting sustainability through integrated transport policies. For example, in Hanoi, the increasing number of motorcycles is responsible for not only environmental damage but also slowing down economic growth. In the long run, the plan is to reduce traffic through a change in urban planning. Through economic incentives and attractive alternatives experts hope to lighten traffic in the short run. While quantitative methods of observing transport patterns are considered foundation in transport planning, the role of qualitative and mixed-methods analysis and the use of critical analytical frameworks has increasingly been recognized as a key aspect of transport planning practice which integrates multiple planning criteria in generating, evaluating, and selection policy and project options. == United Kingdom ==

In the United Kingdom, transport planning has traditionally been a branch of civil engineering. In the 1950s and the 1960s, it was generally believed that the motor car was an important element in the future of transport as economic growth spurred on car ownership figures. The role of the transport planner was to match motorway and rural road capacity against the demands of economic growth. Urban areas would need to be redesigned for the motor vehicle or impose traffic containment and demand management to mitigate congestion and environmental impacts. The policies were popularised in a 1963 government publication, Traffic in Towns. The contemporary Smeed Report on congestion pricing was initially promoted to manage demand but was deemed politically unacceptable. In more recent times, the approach has been caricatured as "predict and provide" to predict future transport demand and provide the network for it, usually by building more roads. The publication of Planning Policy Guidance 13 in 1994 (revised in 2001), followed by A New Deal for Transport in 1998 and the white paper Transport Ten Year Plan 2000 again indicated an acceptance that unrestrained growth in road traffic was neither desirable nor feasible. The worries were threefold: concerns about congestion, concerns about the effect of road traffic on the environment (both natural and built) and concerns that an emphasis on road transport discriminates against vulnerable groups in society such as the poor, the elderly and the disabled. These documents reiterated the emphasis on integration: • integration within and between different modes of transport • integration with the environment • integration with land use planning • integration with policies for education, health and wealth creation. This attempt to reverse decades of underinvestment in the transport system has resulted in a severe shortage of transport planners. It was estimated in 2003 that 2,000 new planners would be required by 2010 to avoid jeopardizing the success of the Transport Ten Year Plan. In 2006, the Transport Planning Society defined the key purpose of transport planning as: ::to plan, design, deliver, manage and review transport, balancing the needs of society, the economy and the environment. The UK Treasury recognises and has published guidance on the systematic tendency for project appraisers to be overly optimistic in their initial estimates. == United States ==

Transportation planning in the United States is in the midst of a shift similar to that taking place in the United Kingdom, away from the single goal of moving vehicular traffic and towards an approach that takes into consideration the communities and lands through which streets, roads, and highways pass ("the context"). More so, it places a greater emphasis on passenger rail networks, which had been neglected until recently. This new approach, known as Context Sensitive Solutions (CSS), seeks to balance the need to move people efficiently and safely with other desirable outcomes, including historic preservation, environmental sustainability, and the creation of vital public spaces. The initial guiding principles of CSS came out of the 1998 "Thinking Beyond the Pavement" conference as a means to describe and foster transportation projects that preserve and enhance the natural and built environments, as well as the economic and social assets of the neighborhoods they pass through. CSS principles have since been adopted as guidelines for highway design in federal legislation. Also, in 2003, the Federal Highway Administration announced that under one of its three Vital Few Objectives (Environmental Stewardship and Streamlining) they set the target of achieving CSS integration within all state Departments of Transportation by September 2007. In recent years, there has been a movement to provide "complete" transportation corridors under the "complete streets" movement. In response to auto-centric design of transportation networks, complete streets encompass all users and modes of transportation in a more equitable manner. The complete streets movement entails many of the CSS principles as well as pedestrian, bicycle and older adult movements to improve transportation in the United States. Since World War II, this attitude in planning has resulted in the widespread use of travel modelling as a key component of regional transport planning. The models' rise in popularity can also be attributed to a rapid increase in the number of automobiles on the road, widespread suburbanization and a large increase in federal or national government spending upon transport in urban areas. All of these phenomena dominated the planning culture in the late 1940s, 1950s and 1960s. Regional transport planning was needed because increasingly cities were not just cities anymore, but parts of a complex regional system. The US process, according to Johnston (2004) and the FHWA and Federal Transit Administration (FTA) (2007), generally follows a pattern which can be divided into three different stages. Over the course of each of three phases, the metropolitan planning organization (MPO) is also supposed to consider air quality and environmental issues, look at planning questions in a fiscally constrained way and involve the public. In the first stage, called preanalysis, the MPO considers what problems and issues the region faces and what goals and objectives it can set to help address those issues. During this phase the MPO also collects data on wide variety of regional characteristics, develops a set of different alternatives that will be explored as part of the planning process and creates a list of measurable outcomes that will be used to see whether goals and objectives have been achieved. Johnston notes that many MPOs perform weakly in this area, and though many of these activities seem like the "soft" aspects of planning that are not really necessary, they are absolutely essential to ensuring that the models used in second phase are accurate and complete . == See also ==
