To deeply explore the educational elements in experimental teaching of road simulation using VISSIM， the ideas and processes of experimental teaching design are analyzed by layers and sections. By optimizing professional courses and the "ideological and political education" system and improving the content of teaching design， our target is to effectively and flexibly integrate "ideological and political education" into every section of experimental teaching. Taking the teaching design of the pedestrian crossing system in the road simulation experiment course as an example， we introduce the “ideological and political factors” flexibly by paying close attention to the practical problems encountered by vulnerable groups in the traffic system. In doing so， we inspire college students to respect the elderly， love the young， and care for others and emphasize the idea of “contributing to the fame of motherland with scientific talents and achievements” . Including the concept of fostering virtue through education in the whole process of road simulation experiments， this teaching design aims to clarify and highlight the teaching objectives of “ideological and political education” and professional courses.
