I would like to know smart cities (concrete and successful) projects that have used sensors and crowdsourcing together to collect and present data using mobile applications. What is your experience?
You can find useful information in the following publications:
[1] Vakali, A., Angelis, E., and Giatsoglou, M. 2013. Sensors talk and humans sense towards a reciprocal collective awareness smart city framework. In Proceedings of the IEEE International Conference on Communications (IEEE ICC) 2013: Workshop on Beyond Social Networks: Collective Awareness

SEN2SOC and EADIC projects can also be useful to your queries. You can have an executive summary at the
Vakali, A., Srdjan, K., and Anthopoulos, L. (2014). Smart Cities Data Streams Integration: experimenting with Internet of Things and social data flows. In the European Data Forum 2014 (EDF2014), March 19-20, Athens, Greece
You should find references there on their work on smart cities, public transportation and crowdsourcing.
