TY - JOUR AB - Purpose The purpose of this paper is to study the unexpected consequences in the operation of urban environments. Prediction within the urban planning process often presents difficulties and unintended consequences. It is not enough to develop a good project. Unexpected consequences are possible because of the environment. The authors argue that these problems of uncertainty can be minimized with citizen participation and the use of new technologies.Design/methodology/approach The problem of how urban planning initiatives result in unexpected consequences is described. These effects are determined by studying a series of cities and real urban environments. A case study on urban accessibility is developed for a better understanding of the problem.Findings Avoiding unexpected consequences in the operation of urban environments is strongly linked to the concept of Smart City 3.0. This concept is based on the co-creation. In this line to address the problem, a citizen-centric methodology using the latest information and communications technologies and internet of things technologies is presented. As a practical application, different categories of unexpected events related to the Faculty of Education building at the University of Alicante have been identified as a consequence of the impact of its environment. An uncomfortable or non-accessible environment causes unforeseen behaviour of individuals.Originality/value There are no analytical tools to investigate how aspects of the urban environment cause uncertainty about the acceptance of projects by future citizen users. This work takes a step forward in that direction.
