بخشی از متن مقاله:
The Transport Laboratory of the National Research Irkutsk State Technical University (TL-ISTU) has been participating in development of the Federal Manual “Quality Evaluation of Traffic Management” since 2014. This article considers a part of the criteria offered in these guidelines. In conditions of high level of saturation of the street and road network (SRN), quality evaluation of SRN projects surely has to include evaluation of conditions of traffic fow movement. Therefore, both projects of SRN sites and traffic management projects being evaluated on the basis of modeling have to get a uniform system of evaluation criteria (i.e. it is necessary to form something that got the name Traffic Analysis Tools in the international practice). Consequently, SRN functioning is characterized by two parameters — reliability and quality of traffic conditions provided to a user. It should be noted at once that the second indicator got an unambiguous definition as a level of service long ago. The approaches to reliability evaluation are much more various. One of the most widespread approaches to reliability determination is assessment of transport system behavior in conditions of congestion. In this context, we interpret congestion as a state (of both SRN and a route system of the public passenger transport, etc.) at which transport demand begins to exceed transport supply. As follows from the analysis of the international practice, special periodicals and literature [Bakhirev and Mikhailov (2015), Rumyantsev and Mikhailov (2010), Rumyantsev (2012), Sharov and Mikhailov (2014), Susilawati and Taylor (2010)] as well as considering the onrush of geoinformation technology, the following quantitative criteria have been chosen to assess reliability: • Time index • Herman–Prigogine criterion • Buffer time and buffer index In conditions of high loading levels of SRN and influence of random factors, time expenditures for trip begin to vary in a wide range of values and have to be considered as a random variable. Consequently, the time index TT1 is a ratio of time spent for passing the site in conditions of a rush hour to way time in conditions of a free flow.
