摘　　要：为了提高出租车运量投放的科学性,基于出租车运行参数(包括出租车平均营运收入、空驶率、平均出行距离、平均行驶速度、平均工作时间以及其他城市环境估计参数)提出了出租车运量投放计划模型,并使用出租车营运收入对模型进行了约束。利用该模型,基于某市2010年的出租车运行数据,对该市2015年的出租车运量投放进行预测。结果表明:到2015年该市需要逐步增加5000veh左右的出租车;2010年底该市增加的1 000veh出租车缓解了部分出行压力,空驶率由0.177增加到0.198;出租车运量增加后营运收入仍略有上升,验证了模型的有效性。In order to improve the scientificity of taxi quantity schedule, a precise schedule model of urban taxi quantity was proposed based on the quantitative parameters of taxi trade from taxi service and management information system pilot project, including taxi average income,unloaded ratio, average traffic distance, average speed and average work time, as well as the other estimated parameters of urban environment. Moreover, the model was constrained by the taxi income. The taxi quantity of a city in 2015 was scheduled with the model based on the taxi service and management information system data of this city in 2010. The results indicate that about 5 000 taxies should be put into the market by 2015. When 1 000 taxies are put into market at the end of 2010, the running result shows that the increase of the taxi quantity has reduced the traffic pressure, and the unloaded ratio of taxi has increased from 0. 177 to 0. 198. In the meantime, the income of taxi drivers has increased a little. The results show that the model is effective.
