Velocity of personal vehicles or traffic flow for a certain period of time and on a certain section of the road is the main indicator that characterizes the impact of road conditions, environment, technical condition of the car and psychophysiological factors on the driver.
To evaluate the each factor impact of on the velocity, survey was conducted on the M-06 Kyiv – Chop road. A cluster analysis of field observation data was performed using the Statistica 12 software, connections were established in the middle of the data set, and the obtained data were organized into certain structures. As a result of the clustering, groups of clusters that have the greatest impact on speed were identified. Determining the hierarchy of factors influencing the speed and safety of the transport process shall improve approaches for modeling traffic flow velocity dependences. The paper describes an analysis of road safety risk factors.
Problem Statement. The need to modernize approaches for traffic flow prediction, traffic volume distribution on the road network, means and methods of traffic management, traffic management systems in connection with quantitative and qualitative changes in the transport sector of Ukraine.
Purpose. Road safety risk factors validation and ranking.
Materials and method. Mathematical modeling and cluster analysis using survey data.
Results. The dependence of speed on road conditions was improved using mathematical modeling.
Conclusions. The hierarchy of factors influencing the speed and safety of the transport process is determined.
