Evaluating the effects of a transport infrastructure improvement on heterogenous household groups using an urban cge model

Topuz, Yunus Bulut
This study evaluates the economic effects of urban transportation policies on different household groups utilizing a CGE model integrated with a discrete choice model and a traffic model. The London Travel Demand Survey (2004) data is utilized basically in this study and two alternative transport policies which are an improvement in public transportation infrastructure and a price increase in the congestion charge are examined. Households are heterogenized according to their living locations, working places, income groups, transport modes and additionally some characteristics of themselves such as having one or more school children or one or more retired persons. Results show that the heterogenization of the households may give crucial insights to the policy makers. Contrary to the general trends, some sub-groups may be affected in different ways as a result of the policy actions.
