Modelling traffic accident causality and built environment in major world cities


Research Centre: Healthy High Density Cities Lab

Project title: Modelling traffic accident causality and built environment in major world cities.

HKUrbanLabs research cluster: Healthy CitiesHD

Project Team: Chinmoy Sarkar (PI), Chris Webster (Co-I), Sarika Kumari (Research Assistant).

Project Funder: None

Abstract:

The objective is to examine associations between various attributes of built environment density, form, street level physical structures, carrying capacity and various aspects of traffic accident casualty (including frequency and severity). The study includes three major cities of London, Hong Kong and Melbourne.

Anticipated outcomes: A series of four publications in high impact journals. Dr Sarkar will put in a book proposal to Edward Elgar or Routledge in June-August 2016.

“The entire layout of all newly developed areas must, if necessary, be made dependent on that safety factor; it would be rather futile to plan, by means of layout, for hygiene and amenity, but at the same time to overlook that this same layout is likely, daily and hourly, to cause death or maiming”.
