城市出租汽车发展规模理论与评价指标的确定

Determination of taxi developing scale theory and its assessment indexes in a city

出租车的总量规模及其控制是出租汽车发展规划中的一个重要环节，也是行业决策管理人员最困难的问题．结合我国几个出租汽车运营状况良好的城市调研数据，运用随机系统理论中的生灭过程法，提出了合理规模下的空驶车与载客车的比例应该在0．2～0．5的范围内，该数值可以为城市出租车现状发展规模是否合理提供参考依据．

The quantitative scale of taxis as well as its control is an important issue and is also the most troublesome problem for the decision-making board. According to the survey statistics from several cities in which the taxi operating status is good, the method of birth and death process in random system theory was used and the proportion of vacant taxies and occupant ones in a reasonable scale should be from 0. 2 to 0.5 was suggested, the suggested figures provide reference for judging whether the present taxi developing scale is reasonable in a city.
