This study introduces the concept of linking together the Urban Transportation Planning (UTP) and urban Dynamic (UD) models by means of some key indices, such as transportation accessibility, population and economic development (i.e. Gross Provincial Project, GPP). It is found that, by repeating the procedure several times, a certain level of socio-economic development can be achieved which will reflect future transportation conditions in the city. In addition, this study also found some new MOE’s (Measures of Effectiveness) concerned with socio-economic development which can be used to measure and evaluate the effectiveness of transportation investment policies on urban growth.
