OPTIMIZATION PROBLEMS ON SUBURBAN TRANSPORT SYSTEMS

By T. M. Grigorovа

Abstract

<p>The paper considers problems that permit to solve such issue as organization of  transport service for suburban population with due account of passenger transport fatigue which is considered as one of subconscious criteria for selection of a travel mode. Improvement of transportation process entails an increase in demand for such service. Demands predetermine transport supply and situation on the market depends on supply-and-demand balance.  The paper presents an analysis of approaches to the estimation of  parameters for a suburban transport system with due regard for influence of transport process parameters on the rate of passenger transport fatigue.  This rate is estimated through value of an index which demonstrates an activity of passenger’s regulatory systems while performing every element of motion process. Nonlinear regression equation has been used to describe changes in the activity index of the passenger’s regulatory systems when a passenger is taking a standing position in a passenger compartment of a suburban transport facility. In this case value of activity index of regulatory systems  before transportation, passenger age, transportation duration,   operation factor of transport  capacity and ratio of new bus cost to nominal capacity have been taken as variables for calculations.</p><p>The paper proposes an index change model for assessment of passenger’s transport fatigue when a passenger has a standing position in a transport facility. The model has shown that an impact of the activity index of passenger’s regulatory systems before  making any elemental motion is rather pertinent because this index provides information on an initial condition of a person before executing any other elemental motion. The influence of the activity index of passenger’s regulatory systems before  making any elemental motion is considered as an important characteristic because it has an impact on passenger’s condition after executing previous elemental motions.  Effects of age on  organism adaptive properties are negative. Transport duration has also negative effect on the activity index of regulatory systems. It has been determined that a higher level of transport facility ergonomics helps to reduce fatigue during the travel.</p
