Abstract
Major cities in developing countries are undergoing massive transportation infrastructure construction, which has significant impacts on the land use and economic activities in these cities. Standard Cost–Benefit Analysis (CBA) is applied to quantify the user benefits of transport projects, but does not provide an answer as to who will obtain the benefits and who will lose out and excludes the calculation of Wider Economic Impacts (WEIs) which can sometimes be large and hardly negligible. This paper introduces thoughts and experiences obtained through the design and development of an integrated land use transport model for the assessment of the WEI of a transport infrastructure project. The development and application of such an integrated model for WEI analysis should help decision-makers understand not only the “direct or immediate” impact of transport infrastructure on mobility, but also those “indirect or long-term” impacts on the distribution patterns of economic activities, corresponding land use, and resulting urban structure.
Highlights
For the past two decades, the study of a range of Wider Economic Impacts (WEIs) or Wider Economic Benefits (WEBs) associated with transport infrastructure projects has caught the attention of many researchers
Researchers argue that large transport projects, together with the appropriate policies, can generate additional benefits over the user benefits calculated in the traditional Cost–Benefit Analysis (CBA) method
This paper introduces thoughts and experiences obtained through the design and development of an integrated land use transport model for the assessment of the wider economic impacts of a transport infrastructure project, especially the agglomeration effect
Summary
For the past two decades, the study of a range of Wider Economic Impacts (WEIs) or Wider Economic Benefits (WEBs) associated with transport infrastructure projects has caught the attention of many researchers. This paper introduces thoughts and experiences obtained through the design and development of an integrated land use transport model for the assessment of the wider economic impacts of a transport infrastructure project, especially the agglomeration effect. An integrated land use transport model for the City of Wuhan, China, which is developed based on a PECAS model, is used to analyze the agglomeration effect of a metro line construction project. The development and application of such an integrated model for WEI analysis should help decision-makers understand the “direct or immediate” impact of transport infrastructure on mobility, and those “indirect or long-term” impacts on the distribution patterns of economic activities, corresponding land use, and resulting urban structure.
