Cultivating undergraduates’ engineering practice ability is to meet the needs of social development for high quality talents. The practice teaching of traffic engineering based on professional projects will reduce the gap between students’ ability and enterprises’ demand. A survey of employers for college graduates in traffic engineering was conducted in Beijing. The results show that the practice application ability is the employers’ uppermost concern. All employers agreed to conduct the practice teaching of traffic engineering based on project. They also gave suggestions for the project form, content and cooperation form of college and enterprise in the practice teaching based on project. The analysis conclusions will contribute to the improvement of practice teaching mode and the comprehensive practice ability of undergraduates in traffic engineering.
