Abstract: There were some typical problems , including safety, driver behaviors feedbacks , vehicle interactions and scenario settings when the simulation experiments and fi!ed tests were used to investigate the speed guidance issues. A new multi-vehicles coordinating speed guidance experiment platform was established by using the program-oriented multi-driving simulator and VIRTOOLS software. And the individual speed guidance strategy for highway system was programmed on the base of the programmable platform. 18 typical drivers were recruited to attend the speed guidance experiments on Cao' an highway (Lianqun Road-Xianghuang Road) in Shanghai. The experiments included single vehicle without speed guidance (SVWOSG) , single vehicle without speed guidance (SVWSG) , two vehicles without speed guidance (TVWOSG) and two vehicles with speed guidance (TVWSG) and 350 driving samples were obtained finally. The temporal-spatial trajectory analysis and ANOVA analysis were used to comp缸e 4 types of experiment. The results show that both SVWSG and TVWSG can decrease the intersection stops effectively and have no significant effects on travel time compared with the SVWOSG and TVWOSG. TVWSG may have certain safety effect on the vehicle at the restricted lane-changing scenarios.

摘要： 针对传统的仿真试验以及实地试验在安全、驾驶行为反馈、斗三辆交互、场景设置方面存在的典型问题，利用开 发型驾驶模拟器以及VIRTOOLS建模软件，开发了面向主干道的多车协同速度引导驾驶试验平台;以此平台为基 础，设计了针对公路干道的个体车辆主动速度引导策略;招募了18名有代表性的驾驶员，以上海市曹安公路(联群 路-翔黄路)路段车速动态引导为例，进行4组速度引导试验，共获得350份试验数据集，运用时空图分析及方差统 计进行对比研究。结果表明:无论是单车还是双车速度引导场景，停车次数均大幅降低，行程时间则无显著差异;在 限制变道场景下，双车速度引导可能会对被引导车辆安全产生一定影响
