The rapid pace of urbanization and economic prosperity have led to a dramatic increase in car population worldwide over the past few decades. The negative externalities associated with car dependency, e.g., traffic congestion, environmental pollution, oil dependence, are of increasing concern among transport researchers and policymakers. Various policy interventions have therefore been proposed in order to accommodate the fast growth of mobility needs while mitigating the negative effects of high car dependency. Examples include transport pricing, land use planning and neo-traditional neighbourhood design. Using the case of Singapore, this talk will focus on two policy interventions — vehicle quota control and transport infrastructure investment. It will discuss their influence on travel behaviour and effectiveness in regulating individual vehicle usage. Specially, the interconnections among individual characteristics, the built environment, transport infrastructure provision, vehicle quota control, and individual mobility choices will be explored using a pseudo panel dataset created with three travel surveys and Structural Equation Modelling.

Siqi is a Postdoctoral Research Fellow at the Lee Kuan Yew Centre for Innovative Cities. She received her PhD in Geography from National University of Singapore and Bachelor’s degrees in both Urban Planning and Economics from Wuhan University, China. Her research interests fall broadly under transportation, urban planning, GIS application, public health, spatial and quantitative analysis, with a special focus on sustainable transport policies and the interaction between the built environment and travel behaviour. Currently, she is working under the Lee Li Ming Programme in Ageing Urbanism, where she explores the role of built environment in shaping health and wellbeing among older adults in Singapore.
