摘　　要：采用广深珠高速公路调查点7 d的实测交通数据,以每天的实测交通数据为研究对象得到基于每天实测交通数据的多车道横向折减系数,以考虑不同时段实测交通数据对横向折减系数的影响,结果表明:不同时段实测数据对多车道横向折减系数的影响较小;同时,通过与内蒙古调查点实测数据的对比分析,研究不同地域对横向折减系数的影响,结果表明:1~5车道横向折减系数受地域影响非常明显,而超过5车道之后,地域对横向折减系数的影响极小。Based on the measured traffic data of Guang-Shen-Zhu Expressway survey points in 7 days, the daily measured traffic data were taken as the research object to obtain the multi-lane transverse reduction factors, and the influence of the measured traffic data in different periods on the multi-lane transverse reduction factors was considered.Results show that the measured traffic loading data in different periods have little influence on the multi- lane transverse reduction factors.At the same time, according to the comparative analysis on the measured traffic data of survey points in Inner Mongolia, the influence of different regions on the multi-lane transverse reduction factors was researched.The results show that different regions have obvious influence on the transverse reduction factors for 1-5 lanes and almost no influence for more than five lanes.
