Abstract:From the perspective of commuters, the commuting distance was divided into three groups including long, medium and short commuting distance and a unified evaluation criteria about the acceptability of travel time was used in this article. From five dimensions of door-to-door travel speed, general cost, reliability, satisfaction and choice ratio, various traffic mode chains in three group of distance are analyzed. Based on the results of correlation analysis between the travel speed, reliability, general cost and satisfaction for each group of commuting distance, judgment criterion of the adaptability was established and the traffic mode chain with good adaptability was selected. Finally, with the characteristic of the traffic mode chain with good adaptability as reference objects, optimization guidance for each traffic mode chain in long, medium and short commuting distance was proposed under the constraint on prior development of public transport, which was used to provide decision reference for the improvement of commuting traffic service.
