Estimation of the traffic flow parameters based on the processing of navigation data on the vehicles movement

Kapski D., Pashkevich A.

Transport Miejski i Regionalny

2018

nr 5

25--32

The article describes the method to estimate the parameters of traffic flows using the two-fluid mathematical model of Herman-Prigogine, which was developed on the base of the proposed method to estimate the system parameters with the passive processing of navigation data on the movement of vehicles. Efficiency of the proposed algorithms as well as mathematical models to estimate the parameters of road traffic flow and system as a whole was confirmed during its testing with the use a set of vehicles on the main highways of Belarus.

Artykuł opisuje metodę oceny parametrów potoków transportowych za pomocą dwupłynowego modelu matematycznego Herman-Prigogine, która została opracowana w oparciu o zaproponowaną metodę oceny parametrów systemu za pomocą biernego przetwarzanie danych nawigacyjnych o ruchu pojazdów. Skuteczność proponowanych algorytmów oraz modeli matematycznych do oceny parametrów potoków ruchu drogowego i systemu jako całości została potwierdzona podczas testu przy użyciu zestawu pojazdów na głównych autostradach Białorusi.

The analysis of various measures of the speed control of the traffic in the cities and settlements of the Republic of Belarus

Kapski D., Korzhova A.

Journal of Sustainable Development of Transport and Logistics

2017

Vol. 2, No. 2

26--34

The results of the analysis of various measures of calm of movement in cities and settlements are presented in the article. The alternative measures of physical and psychological effects on the traffic participants are considered. Particular attention is paid to the application of speed humps. They are installed on the streets of cities and settlements widely. The statistics of road traffic accidents at sites with humps in Minsk are considered. Various aspects of the effect of speed humps on accident rate have been established. And experimental studies of the instantaneous speeds of road vehicles in the installation area of speed humps have been performed. New modifications of speed humps are proposed, the design of which was developed on the basis of research of interactions with the car. Also the study investigated the effect of hump on the accident rate, delays in transportation, changes of speed and flow density. In addition, specific proposals have been developed. They are included in the technical normative legal acts in our country partially. That proposals allows to increase the overall quality of traffic (minimize the total economic, environmental and emergency losses from installation of speed humps). For example, alternative variants of design decisions on improvement of quality traffic safety are considered. In addition, the article considers other measures of forced speed control on streets network of cities and settlements in the country.
