An important problem is the lack of harmonized data, tools and practices in order to guide urban planning teams, politicians and managers to the desired direction. Urban planning is managed by experts, usually assigned by politicians, who apply individual practices according to their experience and the local circumstances.
Lack of reliable and detailed enough data is a major problem touching the problem analysis, planning and monitoring phases. The use of many new tools such as models and various evaluation techniques requires high-quality data on inter-linked urban phenomena and flow of interactions. The lack of comparable data also makes benchmarking and the use of other comparative methods and tools very difficult.
