深圳市公交车行驶工况研究

Study on Shenzhen Bus Route Driving Cycle

  • 摘要: 车辆在特定道路工况条件下的性能能够为汽车系统的设计和改进提供参考。目前, 深圳市还没有建立起典型的城市道路工况。文章基于深圳市 M347 路公交车的行驶数据, 利用主成分分析法和聚类分析法来构建公交车线路行驶工况。由聚类分析将原始短行程数据分为两类, 可以体现公交线路中拥挤和畅通两种不同行驶状况。文章所构建的综合工况能较好地反映该线路的道路工况, 对于研究分析具有深圳特点的行驶工况和优化车辆性能具有一定参考意义。

     

    Abstract: The performance of automotive under specific drive cycles can provide a reference for the development and improvement of vehicle systems. At present, there is no representative typical driving cycle in Shenzhen. In this paper, the development of M347 bus route driving cycle in Shenzhen was reported, combining principal component analysis and clustering analysis methods, and the rationality and the validity of the driving cycle were tested and verified. The original micro-trips are divided into two series by the clustering analysis method, which may explain traffic jam and smooth traffic driving conditions of M347 bus route. The M347 route multiple driving cycle constructed at last can reflect the real-world road conditions.
