Singapore Road Vehicle Fleet Evolution

چکیده
Vehicle fleet modeling is a useful tool to analyze the dynamics of motor vehicles and their environmental impact at a macroscopic level, and has been applied in the USA and Europe. In this article, a road fleet model is constructed for the city-state Singapore. Policies that control vehicle ownership and congestion road pricing employed since 1998 differentiate Singapore’s vehicle market from other markets, making it a particularly interesting case to investigate. The fleet model is constructed using spreadsheets that track vehicle age, vehicle population, vehicle kilometers travelled, fleet fuel use and greenhouse gas (GHG) emissions. The authors hope that the model can be used as a tool to help stakeholders assess the social and environmental impact of relevant policies like capping vehicle growth, scrappage policy, reducing vehicle mileage and adopting green vehicles.

Projecting effects of improvements in passive safety of the New Zealand light vehicle fleet.
OBJECTIVES In the year 2000, as part of the process for setting New Zealand road safety targets, a projection was made for a reduction in social cost of 15.5 percent associated with improvements in crashworthiness, which is a measure of the occupant protection of the light passenger vehicle fleet. Since that document was produced, new estimates of crashworthiness have become available, allowing...
متن کاملA survey of models and algorithms for winter road maintenance. Part IV: Vehicle routing and fleet sizing for plowing and snow disposal
This is the last part of a four-part survey of optimization models and solution algorithms for winter road maintenance planning. The two first parts of the survey address system design problems for winter road maintenance. The third part concentrates mainly on vehicle routing problems for spreading operations. The aim of this paper is to provide a comprehensive survey of optimization models and...
متن کاملBlack carbon, particle number concentration and nitrogen oxide emission factors of random in-use vehicles measured with the on-road chasing method
The chasing method was used in an on-road measurement campaign, and emission factors (EF) of black carbon (BC), particle number (PN) and nitrogen oxides (NOx) were determined for 139 individual vehicles of different types encountered on the roads. The aggregated results provide EFs for BC, NOx and PN for three vehicle categories: goods vehicles, gasoline and diesel passenger cars. This is the f...
متن کاملA Model for Considering the ‘total Safety’ of the Light Passenger Vehicle Fleet
This report describes the results of research to develop and apply a comprehensive model to consider the influence of the mix of vehicle types on the total safety of the light passenger vehicle fleet in Australia. Key inputs to the model are estimates of the crashworthiness and aggressivity of light passenger vehicles in the key crash types representing the majority of crashes in which these ve...
متن کاملSafety related attributes of registered vehicles and of vehicles that crash in South Australia
The objective of this study was to characterise and compare a registered fleet and a crashed vehicle fleet with respect to vehicle attributes related to safety. Two samples of vehicles were examined: a random sample of 2000 passenger vehicles registered in South Australia and all passenger vehicles involved in serious casualty crashes in South Australia in 2008-2009. Vehicles were linked with s...
