The experience of optimization of route network of the city by ecological and economic indicators

Abstract

The article presents a linear programming method (transport problem) applied to simulate the route network of a city. Optimization criteria are indicators of economic, environmental and social assessment. The objective function has indicators of economic costs, environmental and social losses when performing passenger transportation with weight coefficients. Weighting indices choose for each route the importance of economic and environmental indicators, depending on the characteristics of transportation. The scheme of transportation is chosen by the integral indicator (calculate the plan optimal for economic or environmental indicators, or compromise).
The developed approach is applied for improvement of the Kyiv public transport route network on the ecological and economic basis. Optimization of the route network only for individual routes allowed to increase the income and reduce the costs of commuting while reducing the emissions of harmful substances.
Key words: city transport system, itinerary network, passenger transportation, optimization, ecological and economic indicators.
