Modeling green vehicle adoption: An integrated approach for policy evaluation

This article employs an integrated discrete-continuous car ownership model to jointly forecast households’ future preferences on vehicle type, quantity and use, and to estimate greenhouse gas (GHG) emissions. The model system is estimated on a dataset collected from a web-based stated preference survey conducted in Maryland in 2014. The data contain vehicle purchase decisions and sociodemographic information of 456 households who were requested to state their future preferences over a 9-year period (2014–2022). In each time period, a respondent is faced to four alternatives that include the current vehicle, a new gasoline vehicle, a new hybrid electric vehicle, and a new battery electric vehicle. Intertemporal choices between conventional and “green” vehicles such as hybrid and electric cars capture dynamics in vehicle purchase decisions. Short run and medium-long run situations were predicted and compared based on the first 4-year data and the entire 9-year data of the dynamic panel. Vehicle GHG emissions were calculated correspondingly. We find the introduction of “green” vehicles makes a positive impact on car ownership and use, especially in a medium-long run. Two “green” taxation policies, gasoline tax and ownership tax, were proposed and their impact on vehicle use and emission reductions was evaluated. Results indicate that: (a) gasoline tax is a more effective way to reduce vehicle miles traveled and GHG emissions and (b) gasoline tax makes a higher impact on car use and emission reductions in the medium-long run, while ownership tax makes a higher impact in the short run.     

Reducing the ecological footprint of urban cars

This study develops the policy-making capabilities of the Ecological Footprint. The new capabilities we introduce in our Ecological Footprint model allow us to clarify policy options in the face of the increasing management complexity due to a more interconnected and uncertain world. We investigate the effectiveness of three illustrative policy options for reducing the Ecological Footprint of urban car transport: (1) improvements in efficiency/technology, (2) substitution with alternate fuel mixes, and (3) the reduction in demand by altering urban form. We investigate the success of policy options for a subnational case study jurisdiction in Australia, but in the uncertain global context. We use a resilience framework that considers critical social, economic, and environmental variables, multiple scales, and multiple possible futures. We find that delaying policy options to mitigate CO₂ emissions from the transport sector will increase the risks borne by society as a result of future global uncertainty, the uncertain timing of globally coordinated action on climate change and the timing of peak oil. We also find that the success of local policy is affected by the global future which prevails. The use of the Ecological Footprint allows policy to be informed by the consequences of both CO₂ emissions and increasing demand for land. The study provides a decision-making framework that allows local decision makers to make robust policy despite global uncertainty. This framework has wider applicability to other nations and/or subnational jurisdictions worldwide.     

Yours,mine, and ours: A user-centric analysis of opportunities and challenges in peer-to-peer asset sharing

The sharing economy is growing globally in terms of user numbers, service providers, and novel concepts. Peer-to-peer (P2P) asset sharing, or asset rental between private individuals, has attracted the attention of entrepreneurs and researchers alike. P2P asset-sharing networks need to focus on two distinct customer groups: (1) asset owners willing to rent out their assets, and (2) renters interested in renting others’ assets. Despite consumers’ high interest in P2P asset sharing, participation rates lag projections, which is mainly attributable to lack of participating asset owners. This could be problematic for P2P networks as they do not own assets; instead, they rely on a sufficient number of asset owners to participate. Detailed indications on the participation motives of users are required to distinctly position P2P asset sharing and enhance communication of consumer-relevant benefits. To this end, we have engaged in a detailed investigation of participation motives in the P2P car-sharing context. We have conducted in-depth interviews with car owners and renters to derive usage types that represent consumer decision profiles that participate in P2P car-sharing services. Based on our findings, we provide extensive recommendations to entrepreneurs in the P2P asset-sharing market.

Public transport and car-sharing—benefits and effects of combined services

The article presents the results of a German research project, where recommendations for the synthesis of public transport and car-sharing/car clubs are given. In order to determine effects and factors of success of combined services, the adoption process, the mobility behaviour and customer satisfaction were investigated within the context of model projects in two German cities. The results prove that car-sharing is suitable as a supplement to public transport.

Adolescent injuries in relation to economic status: An international perspective

The primary objective of the study was to examine the relationship between patterns in car-to-car crashes involving young drivers and car and driver characteristics and the research design was a national register-based prospective cohort study. Individual records in a cohort born 1970 – 1972 are linked to road-traffic-crash data (1988 – 2000). Subjects' first police-registered two-car crash leading to severe or fatal injury (n = 4875) are identified. Typical crash patterns are highlighted and associations between pattern and both car and individual socio-demographic characteristics are tested. Four crash patterns are highlighted. Male drivers and those with lower educational attainment are over-represented in all patterns. Pattern-based risk levels vary considerably according to car safety level and driver's age at time of injury and socio-economic status. Crash patterns might be considered in young adult driver education systems, bearing in mind the consistent higher risks of male drivers and of drivers with lower educational attainment.
