Stated preference survey methods are being used more in transportation planning to predict travel behavior when traditional methods can't provide enough information. These methods help forecast how people might react to new transport options or policies. Designing these surveys accurately is crucial to get realistic results. Errors and biases can occur, but as these issues are addressed, stated preference techniques are becoming an important part of transport forecasting. Studies in the Netherlands, Australia, France, and the UK have shown the potential of these methods in predicting travel behavior across different populations.
