urban density and climate change a stirpat analysis using city level data
Journal of Transport Geography, 2013Co-Authors: Brantley LiddleAbstract:Two important, increasing trends for those concerned about climate change to consider are urbanization/the importance of cities and energy used in Transport—particularly energy used to achieve personal mobility. While national urbanization levels are not a good indicator of urban Transport demand, there is an established negative relationship between urban density and such demand. This paper uses a consistent, well-known population-based framework (the STIRPAT model) and three separate, but highly related, datasets of cities from developed and developing countries (with observations from 1990, 1995, and 2001) to examine the relationship among Private Transport energy consumption, population, income, urban density, and several variables (e.g., network size and prices) that describe the nature of the public and Private Transport systems of those cities. The paper confirms the now well-established result that urban density is negatively correlated with urban Private Transport energy consumption. In terms of policies, improving Private vehicle fuel efficiency, in particular, and increasing fuel price as well as other ownership/operating costs for Private Transport could have a substantial impact on lowering Transport energy consumption. On the other hand, there is no evidence that further lowering the cost to riders of public Transport would lower Private Transport energy consumption. For cities in developing countries, demographic variables (population size and urban density) are particularly important in determining Private Transport energy consumption. Also, Private Transport energy consumption is considerably less price sensitive in those developing country cities compared to cities in the most developed countries.

Study of Modes Transformation Preferences of Private Transport Based on Travel Characteristics and user Behavior
2018Co-Authors: Nur Khaerat Nur, Lawalenna Samang, M. Isran Ramli, Sumarni HamidAbstract:This research is a study to explore the transformationpreferences of modes of Private Transport (four-wheeled andtwo-wheeled) based on travel characteristics and userbehavior. The design of the analysis approach consists ofdescriptive statistical method to obtain the travelcharacteristics and behavior of Private Transport user in termsof travel costs, vehicle operating costs, mileage and traveltime, accessibility, mobility, service. It also uses Partial LeastSquare (PLS) SEM modeling to obtain the interactive travelcharacteristics of Private Transport preferences, publicTransport services quality to modes of transformation. Fromthe results based on data analysis, it is found out that the travelcharacteristics of the commuters for Private Transport userswith variable indicators of mileage and travel time is expectedto affect the determination of modes of Transport that is fastand time-efficient. In the case of Private Transport preferences,most respondents think that the prestige and traffic culturefactor in using the modes of Private Transport have lessimpact. Next, for prestige factor in using public Transport,most respondents think that it has less impact on the publicTransport service quality. Then for the transformation ofmodes of travel, the Private Transport users prioritize more ontravel time, waiting time and total rate factor to be willing tomove to modes of public Transport which is also followed byother factors.Based on the hypothesis test results, it is found that PublicTransport Service Quality (KPAU) does not significantlyaffect to Transformation (TRF) of 1.644. Commuters travelcharacteristics (KaerPerj) do not significantly affect to PrivateTransport Preferences (PAP) endogenous variable of 0973.Commuters travel characteristics (KaerPerj) do notsignificantly give direct effect to Public Transport ServiceQuality (KPAU) of 1.471. Commuters travel characteristics(KarPerj) significantly give direct effect to Public TransportService Quality (KPAU) of 5,461. Private TransportPreferences (PAP) does not significantly affect to PublicTransport Service Quality (KPAU) of 0.224. Private TransportPreferences (PAP) significantly give direct effect toTransformation (TRF) of 7.401.

THE PREFERENCE STUDY ON Private Transport MODE OF TRANSFORMATION BASED ON USER BEHAVIOR
2018Co-Authors: Nur Khaerat Nur, Lawalenna Samang, M. Isran Ramli, Sumarni HamidAbstract:One of the causes in congestion that the number of vehicles are not proportional to the volume increase.Nowadays, common people prefer to use privite vehiches than public Transport and various reasons such asconvenience, faster travel time, the capacity of public Transport is not operating as it should and so forth. This study is astudy exploring perceptions of transformation preference for personal Transport users (four-wheel and two-wheel) interms of the behavior of the user journey mode. Draft analysis approach consisted of descriptive statistical methods toobtain the user travel behavior and perceptions of personal Transport modes, as well as structural equation modeling(SEM) to obtain travel behavior user interaction modes of Private Transport towards the transformation of modes ofperception. The Expected results are: (1) the characteristics of travel behavior and user perception of personal Transportmodes, (2) interaction model the characteristics of travel and travel behavior user and its relation to perceptiontransformation of Private Transport modes

Can the Electrification of Private Transport Lead to Economic Prosperity
2020Co-Authors: Oluwafisayo Alabi, Karen Turner, Christian Calvillo, Antonios Katris, Jamie Stewart, Constantin BrodAbstract:The UK has set binding targets to meet net zero emissions by 2050 and Transport is one of the key sectors where emissions will have to significantly reduce. While a range of options exist to decarbonise Transport, electrification is currently, seen as a leading option for Private Transport in particular. To facilitate the rollout of electric vehicles (EVs), significant electricity network reinforcement is likely to be needed. However, not least because any investment in the electricity network will have to be paid for by consumers through electricity bills, a key question remains as to how this will impact economic prosperity in the long term. This policy briefing builds on a foundation of CEP research, to report on the impacts on wider economy and economic well-being indicators of investing in the electricity network to facilitate the rollout and of the subsequent impact of shifting from conventional vehicles to the extent of 99% EV penetration by 2050.

Can Private motor vehicle-augmenting technical progress reduce household and total fuel use?
Ecological Economics, 2018Co-Authors: Gioele Figus, J. Kim Swales, Karen TurnerAbstract:This paper demonstrates the importance of modelling energy-intensive household services in general, and Private Transportation in particular, as combinations of energy and other inputs. Initially a partial equilibrium approach is used to analyse Private Transport consumption as a self-produced commodity formed by household vehicle and fuel use. We particularly focus on the impact of Private vehicle-augmenting technical progress in this framework. We show that household fuel use will fall if it is easier to substitute between vehicles and fuel in the household production of Private Transport services than it is to substitute between Private Transport and the composite of all other goods in overall household consumption. The analysis is then extended, through Computable General Equilibrium simulation, to investigate the wider implications of similar efficiency improvements when intermediate demand, prices and nominal income are endogenous. The subsequent reduction in the price of Private Transport service (not observable in market prices) allows the wage measured relative to the CPI to rise whilst the wage relative to the price of foreign goods falls. This simultaneously increases UK international competitiveness, encouraging increased exports and reduced import penetration whilst allowing employment to rise. This provides an additional supply-side stimulus to production, employment and household income.

Can a reduction in fuel use result from an endogenous technical progress in motor vehicles? A partial and general equilibrium analysis
2017Co-Authors: Gioele Figus, J. Kim Swales, Karen TurnerAbstract:In this paper we employ a partial equilibrium approach to model Private Transport consumption as a household self-produced commodity formed by vehicle and fuel use. We show that under certain conditions vehicle-augmenting technical improvements can reduce fuel use. We then extend the analysis through Computable General Equilibrium simulations for the UK in order to investigate the wider implications of vehicle-augmenting efficiency improvements when prices and nominal income are endogenous. With a conventional macroeconomic approach, improvements in the efficiency of household consumption simply change the composition of household demand. However, when we adjust the consumer price index for changes in the price of Private Transport service (not observable via a market price), as advocated in Gordon (2016) there is an additional supply-side stimulus to competitiveness.

Transport cost analysis a case study of the total costs of Private and public Transport in auckland
Environmental Science & Policy, 2006Co-Authors: Astrid Jakob, John L Craig, Gavin FisherAbstract:Abstract The current level of motorised Transportation worldwide is increasingly a social, environmental and economic problem. Transport benefits come alongside injuries and death, unproductive travel time, energy dependence, and environmental damage. One reason for the increasing problem results from externalising various impacts on society. Many of these external – or ‘unpaid’ – costs have only gradually been recognised and most have either been under-valued or are considered impossible to estimate since they have no value in a market. This research assesses the external (unpaid) and internal (user paid) cost of Transport. It focuses on estimating the total cost of both Private and public Transport, using a case study for Auckland, New Zealand's largest city. The external costs are significant −2.23% of the GDP produced by the 1.2 million Auckland region residents in 2001. Of this Private Transport generated 28 times more external cost than public Transport. The internal cost assessment showed that total revenues collected did not even cover 50% of total Transport cost. The research has shown that not only are the external costs of vehicle Transport high, but that contrary to popular belief the total costs of Private Transport are subsidised by public Transport users. This has implications for successful Transport policy options.
