摘要/Abstract

摘要： 为揭示出租车碳排放时空分布特征，本文基于出租车GPS(GlobalPositioningSystem)轨迹数据提取轨迹点间的平均速度和行驶里程等参数，构建COPERT(ComputerProgrammetoCalculate Emissions from Road Transport)微观排放模型量化出租车排放。在此基础上，采用分布拟合分析排放在时间、空间和车辆上的分布特征。最后，基于分析结果提出出租车限行和速度管控两项交通管理措施，并通过数值模拟对措施的减排潜力进行评估。以长治市为例进行实证研究，结果表明，出租车行业存在零和博弈现象，排放更加均匀分布于8:00-13:00和14:00-22:00之间。节点和路段上集聚的排放量服从截断幂律分布，排放量最高的前10%的节点和路段分别汇集了95.59%和74.71%的排放量。评估结果表明，出租车限行政策最高能减少约20.35%的排放量；出租车行驶速度为15m·s-1左右时，排放因子最低，且将速度保持在15m·s-1时，最高能减少21.43%的排放量；选取排放量最高的前10%的路段进行速度管控能减少16.23%的排放，而随机选取相同数量的路段仅能减少2.37%的排放。结果可为城市交通制定精细化的碳排放管控策略和节能减排措施提供支持。

Abstract: To investigate the spatiotemporal distribution characteristics of taxi carbon emissions, this study extracts parameters such as average speed and travel distance between trajectory points from taxi Global Positioning System (GPS) data and constructs the Computer Programme to Calculate Emissions from Road Transport (COPERT) micro- emission model to quantify taxi emissions. Based on this, distribution fitting is used to analyze the distribution characteristics of emissions over time, space, and among vehicles. Based on the analysis results, two traffic management measures—taxi restriction and speed control—are proposed, and their emission reduction potential is evaluated through numerical simulations. An empirical study in Changzhi City shows that the taxi industry exhibits a zero-sum game phenomenon, with emissions more evenly distributed between 8:00-13:00 and 14:00-22:00. Emissions aggregated at nodes and road segments follow a truncated power-law distribution, with the top 10% of nodes and road segments accounting for 95.59% and 74.71% of emissions, respectively. The evaluation results indicate that the taxi restriction policy can reduce emissions by up to 20.35%, maintaining a taxi speed of 15 m ⋅ s-1 results in the lowest emission factor, potentially reducing emissions by up to 21.43%. Implementing speed control on the top 10% of road segments with the highest emissions can reduce emissions by 16.23%, while randomly selecting the same number of segments for speed control can only reduce emissions by 2.37%. The results can support the development of refined carbon emission control strategies and energy-saving measures for urban transportation.
