Models and Sustainability

Transportation planning, or transport planning, has historically followed the political bargaining.

Planners are increasingly expected to adopt a multi-disciplinary 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.[1] For example, in Hanoi the increasing number of motorcycles is responsible not only for environmental damage but also for 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.[2]

United Kingdom

In the United Kingdom transport planning has traditionally been a branch of civil engineering. In the 1950s and 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 else impose traffic containment and demand management to mitigate congestion and environmental impacts. These 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 this 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),[3] followed by A New Deal for Transport[4] in 1998 and the white paper Transport Ten Year Plan 2000[5] 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 jeopardising the success of the Transport Ten Year Plan [1].

During 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.[6]

The following key roles must be performed by transport planners:

  • take account of the social, economic and environmental context of their work
  • understand the legal, regulatory policy and resource framework within which they work
  • understand and create transport policies, strategies and plans that contribute to meeting social, economic and environmental needs
  • design the necessary transport projects, systems and services
  • understand the commercial aspects of operating transport systems and services
  • know about and apply the relevant tools and techniques
  • must be competent in all aspects of management, in particular communications, personal skills and project management.[6]

The UK Treasury recognises and has published guidance on the systematic tendency for project appraisers to be overly optimistic in their initial estimates.[7]

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 singular 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[8] 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.[9] 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.[10] The recent pushes for advancing transportation planning has led to the development of a professional certification program by the Institute of Transportation Engineers, the Professional Transportation Planner, to be launched in 2007. An advanced form of certification - the Advanced Specialty Certification in Transportation Planning was developed by the American Planning Association thereafter in 2011. The Certified Transportation Planner credential is only available for those professional planners (AICP members) whom have at a minimum of eight years of transportation planning experience.

In recent years, there has been a movement to provide "complete" transportation corridors under the "[11]

The Technical Process

Most regional transport planners employ what is called the rational model of planning. The model views planning as a logical and technical process that uses the analysis of quantitative data to decide how to best invest resources in new and existing transport infrastructure.[12]

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 weren’t just cities anymore, but parts of a complex regional system.[13]

Integration with Urban planning

Although a transportation planning process may appear to be a rational process based on standard and objective methodologies, it is often influenced by political processes. Transportation planning is closely interrelated to the public nature of government works projects. As a result, transportation planners play both a technical and a coordinating role. Politicians often have vastly differing perspectives, goals and policy desires. Transportation planners help by providing information to decision makers, such as politicians, in a manner that produces beneficial outcomes. This role is similar to transportation engineers, who are often equally influenced by politics in the technical process of transportation engineering design.

Politics and Transportation Planning

The post-analysis phase involves plan evaluation, programme implementation and monitoring of the results. Johnston notes that for evaluation to be meaningful it should be as comprehensive as possible. For example, rather than just looking at decreases in congestion, MPOs should consider economic, equity and environmental issues.[13]

Ideally, these models would include all the different behaviours that are associated with transport, including complex policy questions which are more qualitative in nature. Because of the complexity of transport issues, this is often not possible in practice. This results in models which may estimate future traffic conditions well, but are ultimately based on assumptions made on the part of the planner. Some planners carry out additional sub-system modelling on things like automobile ownership, time of travel, location of land development, location and firms and location of households to help to fill these knowledge gaps, but what are created are nevertheless models, and models always include some level of uncertainty.[13]

In mode choice, trips are assigned to a mode (usually auto or transit) based on what’s available in a particular zone, the characteristics of the household within that zone and the cost of the mode for each mode in terms of money and time. Since most trips by bicycle or walking are generally shorter, they are assumed to have stayed within one zone and are not included in the analysis. Finally, in route assignment, trips are assigned to the network. As particular parts of the network are assigned trips, the vehicle speed slows down, so some trips are assigned to alternate routes in such a way that all trip times are equal. This is important because the ultimate goal is system-wide optimization, not optimization for any one individual. The finished product is traffic flows and speeds for each link in the network.[13]

The actual analysis tool used in the US is called the Urban Transportation Modeling System (UTMS), though it is often referred to as the four-step process. As its nickname suggestions, UTMS has four steps: trip generation, trip distribution, mode choice and trip/route assignment. In trip generation, the region is subdivided into a large number of smaller units of analysis called traffic analysis zones (TAZs). Based on the number and characteristics of the households in each zone, a certain number of trips is generated. In the second step, trip distribution, trips are separated out into categories based on their origin and purpose: generally, these categories are home-based work, home-based other and non-home based. In each of three categories, trips are matched to origin and destination zones using the data that has been collected.

The second phase is technical analysis. The process involves much technical maneuvering, but basically the development of the models can be broken down as follows. Before beginning, the MPO collects enormous amounts of data. This data can be thought of as falling into two categories: data about the transport system and data about adjacent land use. The best MPOs are constantly collecting this data.[13]
