Traffic Demand Management In Three Historic Cities: Results Of A Multivariate Analysis of Business Attitudes.
The problem of traffic congestion and pollution in cities has become a major focus of UK transport policy in recent years. The government consultation paper, Breaking the Logjam (DETR, 1998), considered two specific traffic demand management policies: road user charges (RUC) and workplace parking levies (WPL). Legislation is now before Parliament to allow local authorities to introduce these policies. A major issue affecting the introduction of traffic demand management policies is the possible economic impacts on the urban business sector. There has been little research on the link between transport factors and urban business performance. There is general evidence that firms located in conurbations tend to perform more poorly than firms located in other areas (see, for example, Moore et al., 1980; Fothergill and Gudgin, 1982; Fothergill et al., 1984). There is also evidence that inner city firms perform more poorly than those in outer city locations. For example, Dobson and Gerrard (1991) find that engineering firms located in the inner Leeds area tend to have a lower level of profitability than engineering firms located in the outer Leeds area. Transport problems are one possible important cause of these location effects on business performance. This is supported directly by evidence that transport factors are an important influence on commercial location decisions (Nelson et al., 1994). Of all of the possible business reactions to the introduction of traffic demand management policies in urban areas, the potentially most important in economic terms is the relocation of businesses out of the urban core. Any significant degree of business evacuation of the urban core would have a profound impact on the ability of the urban economy to support the local population. In addition, any spatial restructuring of the local economy would have implications for traffic flows, shifting the locations of major traffic attractors from the urban core to the periphery. Although this may alleviate congestion in the urban core, it may serve only to create congestion elsewhere rendering traffic demand management policies somewhat counter-productive in the long run. The objective of this paper is to report the results of a multivariate analysis of business perceptions of current transport conditions and attitudes to traffic demand management policies based on a survey of firms in three historic cities - Cambridge, Norwich and York. A key component of the survey is the information provided on whether firms are currently considering relocation and the likely impact of the introduction of RUC and WPL on the next location decision. Basic data analysis of the survey responses indicates that the overwhelming majority of firms would definitely or possibly consider relocation as a response to the introduction of traffic demand management. The multivariate analysis seeks to identify those factors that have a statistically significant effect on the probability of relocation as a response.
The structure of the paper is as follows. Section 2 briefly outlines the methodology of the multivariate analysis. Section 3 provides details of the data set used for the multivariate analysis. Section 4 presents the results of the multivariate analysis of the factors influencing the perception of acute transport problems, current relocation considerations, and relocation as a response to RUC and WPL. The final section provides a summary of the findings and a discussion of the policy implications
Programming matrix optics into Mathematica
The various non-linear transformations incurred by the rays in an optical
system can be modelled by matrix products up to any desired order of
approximation. Mathematica software has been used to find the appropriate
matrix coefficients for the straight path transformation and for the
transformations induced by conical surfaces, both direction change and position
offset. The same software package was programmed to model optical systems in
seventh-order. A Petzval lens was used to exemplify the modelling power of the
program.Comment: 15 page
Territoriality, Risk Perception, and Counterproductive Legal Structures: The Case of Waste Facility Siting
The siting of hazardous and nuclear waste facilities has proven to be a task of enormous difficulty in our federal system. In this Article, the Author argues that one of the major causal factors for this difficulty is that the legal regime surrounding waste facility siting decisions is not structured in a manner sensitive to the human factors involved. The siting of a hazardous waste facility is likely to generate a negative community response where the imposition of externally made decisions and externally generated wastes fails to take into account the innate human trait of territoriality. Territoriality is a powerful and instinctive trait embedded in the dynamics of all human communities. When laws attempt to run counter to such a basic aspect of the human psyche, they are likely to be unable to accomplish their purpose. This has been the outcome of the current waste facility siting legal regime. The Author addresses these concerns and ends this Article with a model of comprehensive waste facility siting legislation which takes into account the territorial instinct of states and local communities and would therefore be much more effective in achieving the national goal of providing safe long-term disposal of waste material in a fair and equitable manner
Environmental Law in 2049: A Look Back
December 22 marks the 40th anniversary of the National Environmental Policy Act, which started the modern era of environmental law, and the 40th anniversary of the Environmental Law Institute, which was founded to monitor the new field and to create a profession around the emerging discipline. To mark this anniversary, we asked a range of luminaries to forecast how environmental law and the profession dedicated to its successful implementation will mature over the next four decades. Will environmental protection still be the product of a social movement, or will it have become incorporated as part of the cost of doing business? Will businesses go beyond their legal requirements and lead the movement to sustainability, or will government still be wielding carrots and sticks? Will individuals modify their lifestyles, or will technology make increased environmental quality a natural outcome of economic improvement

Environmental Justice and Natural Areas Protection Trends & Insight
There are 3,119,963 square miles in the continental United States. That sounds like plenty of space to put just about anything. However, when the facility seeking a home is environmentally controversial, finding even one square mile can seem almost impossible.
This country is now in its third major era in making siting decisions. The first era – unconstrained siting – lasted until the late 1960s. Then began the second era – protecting natural areas. In the early 1990s, we embarked upon a third era – environmental justice. The growing tensions between protecting natural areas and achieving environmental justice suggest that we should strive for a fourth era, in which these two important goals are reconciled and allowed to work together
Direct Air Capture: An Emerging Necessity to Fight Climate Change
The Paris Agreement of 2015 declared that we must keep global average temperatures well below 2.0°C (3.6°F) above preindustrial levels, and as close to 1.5°C as possible. However, a 2018 report from the Intergovernmental Panel on Climate Change (IPCC) showed that even 2.0°C would be catastrophic; 1.5°C should be the firm goal. We are now around 1.0°C and are already seeing wildfires, hurricanes, inland precipitation, and other events of unprecedented magnitude
Reflections on Environmental Justice
Environmental justice is a very hot topic. Yesterday\u27s New York Times on the front page of the Metropolitan section had a story stating: Mid-Sized Plants Headed to Poor Areas. The story stated, The Pataki administration acknowledges in its own study that the electric generators that it wants to install around New York City would go into poor heavily minority communities, a finding that supports some of the arguments of the project\u27s opponents. This is quoting an unreleased environmental justice analysis that may or may not be valid, but it certainly shows how hot a topic it is. This morning I would like to say a couple of words about what environmental justice is, on what is the over-arching law on the subject at the federal level, and then to speculate a little bit – we\u27re still at such an early stage that only speculation is warranted – as to how it will affect SEQRA [State Environmental Quality Review Act] and related processes.
Reducing Legal Hurdles to Combined Heat and Power in New York
Combined heat and power (CHP or cogeneration) is the simultaneÂous production of electricity and thermal energy from a single fuel source. Most CHP systems in New York City use natural-gas fired turbines or reciprocating engines to generate electricÂity and then capture heat from the comÂbustion generator’s exhaust stream and cooling systems
Environmental and Energy Legislation in the 112th Congress
When Barack Obama succeeded George W. Bush in January 2009, backed by solid majorities in both the House and the Senate, the country seemed poised for the first major environmental legislation since 1990, the year of the Oil Pollution Act and the 1990 Clean Air Act amendments. Under the leadership of Rep. Henry A. Waxman (D-CA) and Rep. Edward Markey (D-MA), the House passed a comprehensive climate change bill based on an economywide cap-and-trade system. The House also passed a bill to lift oil spill liability caps and adopt additional reforms in the wake of the Gulf of Mexico spill. But both bills languished in the Senate
