###### Abstract  
In the area of smart cities, great emphasis is placed on many different fields such as energetics, information systems, and transportation. All of these should lead to a simplification of life thanks to smart technologies. If we talk about the transportation field, the main issues related to this area are safety, traffic efficiency, or the environment. Another condition is the successful acceptance of any new technology by its users. Cooperative systems prove to be a suitable solution for these issues, especially in urban areas. Today, pilot implementations of cooperative systems in European countries are being carried out. However, before they are put into full operation, they need to be tested, evaluated, and assessed. This article focuses on the latter two points, i.e., evaluation and assessment of the cooperative systems. For this purpose, a methodology was created, which describes the procedure chosen in the evaluation and assessment of cooperative systems in the Czech Republic and a demonstration of its use by example. The methodology is focused on three main areas, which in this case are functional evaluation, user acceptance, and impact assessment. For the area of user acceptance, the main source was questionnaires, impact assessment relied on measured data while functional evaluation was based on discussions with the drivers, evaluating the cooperative systems, the measured data, and the expert observations. All collected and measured data were then processed and some of the results of the evaluation of the selected service are presented at the end of this article.

this event. Before C-ITS is put into full operation, C-ITS must not only be tested but also evaluated and assessed.  
One of the largest pilot projects dealing with individual aspects of C-ITS in Europe is called C-Roads. The C-Roads is a joint initiative of states with road operators and other partners involved in the testing and implementation of C-ITS with a focus on interoperability and harmonization at the European level. C-Roads addresses all fundamental issues related to C-ITS, including evaluation and assessment, which are the main subject of this article.  
At the national level, C-ITS can be deployed and tested at selected pilot sites. Furthermore, there can be an evaluation and assessment of these systems in the form of selected use-cases.  
The evaluation process could be deployed after the successful field testing is completed. Therefore, the evaluation is no longer focused on standards and specifications within the evaluation. The evaluation process is performed to determine the benefits of C-ITS.  
This article deals with the methodology of C-ITS evaluation and assessment in the Czech Republic and demonstrates its use in practice in the form of the performed evaluations.  
The presented methodology and example results have the advantage of working with real data from an existing C-ITS system in the field with test drivers, not just simulation or data from test circuits. Furthermore, the concept of two runs (with and without C-ITS technology) proved to be useful to compare these two approaches. The inclusion of additional sensors to evaluate the runs is also beneficial.
