Urban agglomeration is a regional unit or spatial form of urbanization and economic integration development. Since governments attach more and more importance to the urban agglomeration, the development of urban agglomeration has been rapidly advanced. However, the problem of insufficient and disequilibrium development of urban agglomeration is becoming very outstanding. Therefore, scientific assessment of the urban agglomeration development equilibrium can identify problems and rationally plan for their coordinated development in the future. We use the passenger car data which can better reflect the economic interaction between urbans within an urban agglomeration as the basic data. Then we extract the origin and the destination (OD) of each car trip by combining with the point of interest data close to the road network. Each car trip can be regarded as an interaction between the OD point. In this paper, we take the Changsha-Zhuzhou-Xiangtan Urban Agglomeration (CZX UA) as the research object. We select car interaction intensity, urban GDP per capita, urban road mileage per unit area and car ownership per capita in CZX UA as the indicators to comprehensively evaluate the development equilibrium of CZX UA. The result reflects that there is a big difference between the interaction in urbans and the development degree from the eastern to the central regions of CZX UA is gradually decreasing, which can proffer advice for the future coordination and sustainable development of CZX UA.
