Апстракт:
Traffic flow speed is one of the main causes of the increased risk of traffic accidents and severe consequences, which is why it represents one of the key factors for the traffic safety level increase. Speed limit posting is key part of speed management, but inadequately posted speed limits causes their disregard. In this paper, using analytical models and methods, the new concept of speed limit credibility analysis, based on the analysis of operating speed in function of different traffic flow classes, is introduced. A total of 17 road segments with various traffic flow characteristics was analyzed, for one of which field research was conducted. It was found that the resulting values of speed are closer to traffic flow 85th speed percentile. Also, resulting values are closer to target drivers group which should be integrated in speed management policy. On the basis of the above mentioned, it can be concluded that the new concept represents an adequate measure for speed limit credibility analysis and defines the basis for further operating speed model improvement.
