Quality Assessment of Passenger Transportation by Urban Transport while Using Various Number of Fixed-Route Transport Facilities
The quality of services which are offered by urban passenger transport determines a living standard of country’s inhabitants. The executed analysis of methods for quality assessment of passenger transportation service by urban transport has shown that it is expedient to use complex indices for such assessment. The existing methods for quality assessment of urban passenger transport do not fully take into account subjective passengers’ evaluation of service quality criteria. The investigations conducted with the purpose to estimate significance of quality assessment criteria pertaining to urban passenger transport operation for passengers have made it possible to formalize importance of the given significance. A complex index of urban passenger transport quality has been prepared that includes such isolated quality indicators as pedestrian motion component, waiting time, travel time, dynamic factor of capacity usage. It has been determined that it is possible to plan quality of passenger transportation while using transport process simulation. Influence of technological parameters on quality parameters can be determined with the help of the developed simulation model for quality assessment of transportation process on route of urban passenger transport. While using the simulation model regularities in changing a complex quality index of urban passenger transport have been analyzed according to number of transport facilities operating on route. Simulation results have shown that changes in number of transport facilities significantly exert an influence on the value of dynamic factor of transport facility capacity usage, waiting time for transport facility and time travel. This leads to changes in quality of transportation process. Analysis of the obtained results has permitted to make a conclusion that every route with certain parameters has such rational number of transport facilities that ensures maximum efficiency of urban passenger transport with appropriate quality. It has been revealed that any change in number of transport facilities is described with a reasonable degree of accuracy by a nonlinear regression equation where parameters of transport facilities, passenger traffic flows and route are used as independent variables.
