Improvement of Technique for Assessing Dedicated Bus Lane Efficiency in Large Cities
This article examined and analyzed the existing conditions for introducing a dedicated bus lane for urban transport in foreign countries using the case study of South Korea, the USA and the UK and Russia, and determined the optimal parameter by which it is advisable to evaluate the effectiveness of the transport system of any large city. The paper gave an overview of the existing methodology for introducing a dedicated bus lane on the parameter of total delay time with formulas and explanations for them, and description of the benefits and drawbacks of this approach. A new technique was proposed allows for more accurate calculations and draw conclusions about the need to introduce a dedicated bus lane for urban transport based on a parameter list that should be obtained from surveys of the road network of a large city. The performance parameters of the dedicated bus lane were calculated according to the proposed and existing algorithm and according to surveys of the volume of traffic of urban transport and private vehicles, the speed of traffic in a busy and free network, ridership and others. The calculations performed gave the identical qualitative result about the need to use dedicated lanes, but led to different quantitative values differing more than 10 times. This is very important for assessing the effectiveness of the organization of urban traffic using dedicated lanes.
