The study aims to prepare a neural network model considering predictor variables such as big data in urban planning, effective governance, resource management, and knowledge based economy for sustainable development in smart cities. A sample of 212 survey responses was collected randomly from Oman and analysed in a neural network model. The predictors' contributing to sustainable development in smart cities are big data in knowledge based economy (.299), big data in governance (.251), big data in urban planning (.225), and big data in resource management (.224). Overall the neural network model consisting of predictors' was able to predict 60.0% correctly during training and 72.6% during testing for sustainable development in smart cities.
